A Zero Distance Between MAXGE ELECTRIC and AI

“There will be only two kinds of enterprises in the future, artificial intelligent  and unprofitable.”——TCS 《2017 Annual Report of Global Trend》

Today, as an ordinary worker, how far is it from artificial intelligence?

Last night, Mr.Zhang saw an American movie called “Western World” when he  could only touch the artificial intelligence by artistic imagination.

.In the morning, Mr.Zhang browsed news on the way to work and saw a variety of information about AlphaGo. Now the distance between him and the artificial intelligence is just as the one between news and life.

As a warehouse keeper working for 10 years in MAXGE ELECTRIC, he found that everything in the warehouse was placed in an updated position. In the evening, he also found it very smooth and easy to move goods today, the workload of which was equal to that of the past half-day. At this time, artificial intelligence has affected his work and become his vital colleague and partner that he can’t even see or touch.

Cases above are not far away, and it is just happening today. In the field of AI for enterprise service, there are cases that it has helped enterprises achieve the warehousing system optimization by a deep calculation. Results shows that after the optimization, the warehouse keeper walks from 30,000 steps reduced to 20,000 steps and working efficiency is improved by 30%.

Artificial intelligence also has happened to Mr. Zhang’s wife, Mrs. Wu, who is engaged in production management for 10 years in MAXGE Electric. She is responsible for orders management every day. Tracking the orders becomes her top priority, taking up two-thirds of her working time.However, today when coming to the office, she found a new AI smart module, ERP system, through which she just needs to knock the keyboard at the seat for production  management, as well as her assistant, who just stops calling and urging the human resources for recruit.

This may indicates that the distance between artificial intelligence and people is infinitely close to zero.

The annual report global trends from a world-renowned consulting firm,TCS, reveals that 84% of the enterprises surveyed around the world regard artificial intelligence as a key element of competitiveness.

From the amazement at AI to the utilization of AI, what else do we need to do?

1、Production Efficiency Optimization

Artificial intelligence entering the enterprise is to optimize the data structure by  understanding the enterprise data, and work out the reasonable manufacturing model by intelligent calculating. Therefore, the efficiency of intelligent artificial  is more greatly improved than that of manual judgement.

For example, in the case of sample testing, in the past, MAXGE Electric was always mainly relied on manual inspection and experience judgment,which led to higher mistake and lower efficiency due to the manual technical ability and lack of the talent. However, in the era of intelligence, MAXGE Electric accurately judges the equipment and products through image recognition and automatic correction system, which has greatly improved its efficiency.

Costs Reduction

By the artificial intelligence technology, the enterprise can not only improve the product qualification rate, reduce labor costs, but also can increase the production safety. What’s more, It is also available to improve the quality of manual by the tool of artificial intelligence and reduce the costs on many aspects of the enterprise.

For example, for the Finance department of MAXGE, filling all kinds of invoices is quite essential. However, traditional manual filing is very labor intensive and easy to make mistakes. MAXGE,with the intelligent OCR system, can quickly convert the invoice document into an electronic version, which has saved a lot of labor time and cost for efficiency improvement.

In addition, artificial intelligence can also contribute to reducing social costs and improving social efficiency and ecological environment. In the process of product testing, the constant temperature of the testing room is an important factor for inspection. Through the artificial intelligence technology, it can precisely adjust the heating of the testing room according to the indoor and outdoor temperature, and finally achieve that the power consumption could be reduced by 10% under the condition of 30℃ in the room. It is a big advancement of temperature adjustment compared to the traditional manual operation.

From “Concept” to “Application”: MAXGE has an access to it.

It should be noted that in the process of artificial intelligence moving from concept to reality, it is still not clear how to apply the concept to the industry. Many enterprises have invested a lot of resources to build artificial intelligence, but the results are not so satisfactory.

In such a fast updated trend, when faced with the clear future and difficulties as well, MAXGE is entering the intelligent world by several appropriate ways.

1、 Get a quick access to artificial intelligence through cloud service.

2、looking for mature intelligent solutions.

3、Improve the intelligence by academic advantages.

It will become one of the main themes in the next long time for MAXGE from intelligence concept to practical application.

Causes of leakage of the leakage protector

Causes of leakage of the leakage protector

一:the wiring error

If the electrical equipment is not properly wired. The adjacent branch power supply line neutral lines are connected to each other. The wrong method of using the number of poles of the leakage protector is incorrect (such as the three leakage protection switches used in a single power grid). It is easy to cause the leakage protector to malfunction.

二: improper grounding

This situation includes: zero line repeated grounding. Self-divided transformer grounding point shunt. There are several reasons for improper grounding of the metal outer layer of the metal armored cable in the zero-sequence current transformer detection circuit.

三:the malfunction caused by overvoltage

When there is lightning overvoltage or overvoltage in the power supply line. Because the overvoltage amplitude is large and the frequency is high. The cable/line-to-ground equivalent capacitance impedance is small. This causes the charging current to be large, causing the leakage protection to malfunction. This is why the surge protector is installed in the grid.

Malfunction

四:electromagnetic interference

If there is a high-powered appliance near the leakage protection switch or there is such an industrial control electronic device such as a soft starter of the inverter. The interference magnetic field (or electromagnetic pollution) generated by this part of electrical equipment. Sometimes it will lead to missed mistakes. To this end, this part of the circuit is often equipped with an electromagnetic absorption or suppressor. To avoid this happening.

五:Implicated by the attached overload and short circuit protection functions

Some of the leakage protection switches now have overload protection. Short circuit protection. In operation, it is common to improperly set the action current of the trip unit due to overload or short circuit protection. The misoperation caused by the leakage protection switch is involved.

六:the circulation impact

If there are two power transformers running in parallel in the power supply system. If each transformer’s neutral point has its own ground wire. And when the impedance difference between the two transformers is large. Then there will be circulation in the grounding wires of the two transformers. When the circulation reaches a certain value. This will cause the leakage protection switch to malfunction.

What is an Residual Current Device(RCD)?

Residual Current Device (RCD) is a leakage protection device. The leakage protection device is a low-voltage safety protection device, and its functions are as follows:
1. Used to prevent single-phase electric shock accidents caused by electric leakage;
2. It is used to prevent fires and equipment burning accidents caused by electric leakage;
3. Used to detect and cut off various phase-to-phase faults;
4. Some leakage protection devices can also be used for overload, overvoltage, undervoltage and phase loss protection.

Residual Current Device

Its working principle: When electrical equipment leaks, it will show abnormal current and voltage signals. The leakage protection device detects the abnormal current or abnormal voltage signal, and the signal processing causes the actuator to operate. The power supply is quickly cut off by the switch device, and the leakage protection device is operated according to the fault current. The leakage protection device is a current-type leakage protection device, according to the fault voltage. The action is a voltage type leakage protection device.

The following mainly introduces the current type leakage protection device (RCD).
There are three main components in its composition, namely, detection components, intermediate links (including amplification components and comparison components), and actuators. Second, it also has an auxiliary power supply and test equipment.
(1) Detection component. It is a zero sequence current transformer as shown. In the figure, the phase line and the neutral line of the protected main circuit pass through the loop core to form the primary coil N1 of the transformer, and the winding uniformly wound on the loop core constitutes the secondary coil N2 of the transformer. The function of the detecting component is to convert the leakage current signal into a voltage or power signal and output it to the intermediate link.
(2) Intermediate links. Its function is to process the detected leakage signal. The intermediate link usually includes an amplifier, a comparator, a trip unit (or relay), and the like. Different types of leakage protection devices have different types of specific configurations in the intermediate links.
(3) Implementing agency. The mechanism is configured to receive an instruction signal of an intermediate link, perform an action, and automatically cut off the power source at the fault. The actuators are mostly automatic switches or AC contactors with shunt release.
(4) Auxiliary power supply. When the intermediate link is electronic, the auxiliary power supply serves to provide the low voltage power required for the operation of the electronic circuit.
(5) Test device. This is the device used to periodically check the running earth leakage protection device. A branch circuit in series with a check resistor is usually used to simulate the path of the leakage to verify that the device is functioning properly.

Home decoration wire connection

Home decoration wire connection

For house renovation. Hydropower projects are extremely important because they are always relevant to our future lives. And once there is any hidden trouble, not only maintenance is not easy. Still difficult to find. How to connect the wire connector in the house decoration to be less susceptible to damage and heat. If you have time, you can also compare the standard of wiring in your home.

First, the composition of the wire:

FireWire (English LIVE) L is generally red or yellow or green

Neutral (English NEUTRAL) N (neutral) is generally blue

Ground wire (English EARTH) E is generally yellow green (flower line) or black

Second, what is the wire connector

Wire connectors are also called wire ends. After the wires are laid. In order to make it a continuous line. Each line must be connected to the whole. These connection points are called cable connectors.

The cable joint in the middle of the wire line is called the intermediate joint. The cable joints at both ends of the line are called terminal heads.

wire

Third, how to connect the wire connector

4 to 6 square millimeters of wire, the length of the joint is not small and 6 times the diameter. The copper wire double-stranded outside the network cable was used to remove one. Then soldered. This does not hurt the line and maintains good electrical conductivity.

The phenomenon that the wire connector is hot. Generally speaking, there is an odor around the wire joint. It can be smelled that this is due to the heat generated by the wire joint causing the outer insulating layer to produce an odor. Secondly, the wire joints emit smoke, red, and the outer insulation layer is black, fire, or even broken.

The heat of the wire connector not only causes a large amount of power loss. Moreover, it will seriously affect the normal operation of electrical equipment, and the operating current in the line will increase. The life of electrical equipment is shortened. Heavy will suddenly interrupt ongoing production, research, medical procedures and other activities. It can also cause fires and electric shocks, and so on. Causes an incalculable loss.

The difference between knife switch, fuse, disconnector, load switch, circuit breaker

A low-voltage circuit breaker (also called an automatic switch) is a switching device that can turn on and off normal load current and overload current, and can turn on and off short-circuit current. In addition to the control function, the low-voltage circuit breaker has certain protection functions, such as overload, short circuit, overload, undervoltage and leakage protection.

1, knife switch

The knife switch is a manual electric appliance used in the low voltage circuit to invert and disconnect the circuit infrequently, or to isolate the power supply, so it is also called “isolation switch”.

The knife switch is a simple manual electric appliance, which is mainly composed of a handle, a contact knife, a static socket and an insulating bottom plate, as shown in the following figure. The knife switch generates an arc when the power is turned off, so the handle must be facing up when installing the knife switch, and must not be flipped or mounted.

When wiring, connect the power cable to the upper end and the load to the lower end. After the brake is opened, the blade is isolated from the power supply to prevent accidents.

Commonly used knife switches include HD series and HS series plate cutter switches, HK series open type load switches and HH series enclosed load switches.

2, fuse

The fuse is a short-circuit protection device with simple structure, convenient use, low price and effective control.

The structure and working principle of the fuse: The fuse is mainly composed of a melt (commonly known as a fuse) and a melt tube (or a fuse holder) in which the melt is installed. The fuse’s melt is placed in series with the protected circuit. When the circuit is operating normally, the melt is allowed to pass a certain amount of current without being blown.

When the circuit is short-circuited or severely overloaded, a large fault current flows through the melt. When the heat generated by the current causes the melt temperature to rise to the melting point, the melt blows and cuts off the circuit, thereby achieving the purpose of protection.

Classification of fuses: There are many types of fuses. According to the structure, they can be divided into plug-in fuses, spiral fuses, closed-tube fuses, fast-acting fuses and self-resetting fuses.

fuse

3, circuit breaker

A low-voltage circuit breaker (also called an automatic switch) is a switching device that can turn on and off normal load current and overload current, and can turn on and off short-circuit current. In addition to the control function, the low-voltage circuit breaker has certain protection functions, such as overload, short circuit, overload, undervoltage and leakage protection.

The structure and working principle of the circuit breaker: The low-voltage circuit breaker is mainly composed of a contact, an arc extinguishing device, an operating mechanism and a protection device. The protection of the circuit breaker is realized by various trip units. The trip unit of the circuit breaker is in the form of an undervoltage release, an overcurrent release, a shunt release, and the like. A low-voltage circuit breaker (also called an automatic switch) is a switching device that can turn on and off normal load current and overload current, and can turn on and off short-circuit current. In addition to the control function, the low-voltage circuit breaker has certain protection functions, such as overload, short circuit, overload, undervoltage and leakage protection.

4, load switch

The load switch can be disconnected with load and has self-extinguishing function. Isolation switches are generally not capable of breaking with load. There are no arc-extinguishing covers on the structure, and there are also isolating switches that can break the load, but the structure is different from the load switch, which is relatively simple.

5, isolation switch

The isolating switch does not have a protection function, and the load switch has an overload protection function. The combination of the load switch and the fuse can automatically trip and have some functions of the circuit breaker. The circuit breaker can have short circuit protection, overload protection, leakage protection and other functions.

The essential difference between a load switch and a circuit breaker is that their breaking capacity is different. The breaking capacity of the circuit breaker can be made high during the manufacturing process, but the breaking capacity of the load switch is limited. The protection of the load switch is generally protected by a fuse, only quick-break and over-current. The circuit breaker mainly relies on the current transformer and the secondary equipment to protect the load switch is mainly used in opening and closing stations and distribution transformers with a small capacity (less than 800KVA).


Circuit breakers are mainly used in motors with frequent breaking loads and large-capacity transformers and substations.
The load switch can break the normal load current and has a certain arc extinguishing capability; the isolating switch does not have any breaking capacity, and can only be disconnected without any load current, which acts to isolate the electric. He is usually installed in the load switch. Or the two ends of the circuit breaker function to isolate the electrical load when the load switch or the circuit breaker is repaired; the circuit breaker has the function of breaking the accident load, and cooperates with various relay protection to protect the electrical equipment or the line;

The isolating switch is a switch that satisfies the isolation requirement in the disconnected position, and the load switch is a switch capable of breaking the normal load current. The circuit breaker is a protective device with overload, short circuit and under voltage protection.


The isolating switch, also called the maintenance switch, has an obvious breaking point during maintenance; it can only disconnect the small current, and generally does not allow the load to be isolated.

The circuit breaker is generally used in low-voltage lighting, the power part can play the role of automatically cutting off the circuit, and the isolating switch is used in the high-voltage part, in the substation, the high-voltage incoming line advanced isolation switch, and then connected to the primary side of the transformer In this way, the function of controlling the on and off of the high voltage incoming line can be realized.

The isolating switch acts as an obvious disconnect point in the electrical circuit and is electrically isolated to ensure safety during electrical maintenance. Can not operate in the event of a fault, no protection for the line and equipment. The circuit breaker has many functions such as overload and short circuit protection, but the load at the lower end has problems and needs to be repaired. The isolating switch functions as electrical isolation. The creepage distance of the circuit breaker is not enough.
There is now a circuit breaker with isolation function that combines the functions of a common circuit breaker and an isolating switch.


Circuit breakers with isolation function can also replace the isolating switch, as long as you are not afraid of more money and more burning, in fact, the isolating switch can not be operated with load. The circuit breaker has short-circuit, overload protection, undervoltage and other protection functions. The isolating switch is not only used at high pressure, but also has many useful isolating switches at low pressure. For overhaul, accident removal, etc.

It should be noted that the power transmission must be combined with the isolating switch and the circuit breaker. When the power is off, the circuit breaker should be disconnected and the isolating switch should be disconnected. In short, it is for operation without load. So use the order of switching.

The isolating switch is prepared for maintenance and the circuit breaker is prepared for protection.

Photovoltaic modules quality issues

In recent years, the photovoltaic industry has developed rapidly, and the number of installations of photovoltaic power plants is also increasing. The quality of photovoltaic modules will directly affect the power generation of photovoltaic power plants, and the failure of photovoltaic modules is also increasing.
As we all know, the entry of solar photovoltaic products into the market is basically through the certification requirements of various countries. Why are there such serious quality problems? There are several reasons:

photovoltaic modules

1. The test standard of photovoltaic modules is not perfect.

At present, the main component testing standards used in the industry are: “IEC61215:2005 Design and Identification of Crystalline Silicon Photovoltaic Modules for Surface Use”, “IEC61730-1:2004 Structural Requirements for Safety Identification of Photovoltaic Modules”, and IEC61730-2:2004 Photovoltaics Experimental Requirements for Component Safety Appraisal and UL1703:2004 Planar Photovoltaic Modules and Flat Panel Standards, and these standards are for single-component components, and the simulated outdoor environment is a single factor or two or three factors in the actual outdoor environment. The azimuth of the analog component is 25 years of outdoor power generation. Have you noticed that none of the test standards mentioned above have a test standard declaration or indicate that all items that have passed this standard prove that the component has a service life of 25 years.

Therefore, the International Electrotechnical Commission is also working on some new standards for the current industry, such as “IEC61701: 2011 Salt Spray Test Standards”, “IEC62804 (draft) Potential Induced Attenuation Effect Test Standards”, “IEC62716:2010 Photovoltaic Modules” Ammonia Corrosion Test Standards. China Quality Certification Center launched “CQC3303-2013 Ground Crystalline Silicon Photovoltaic Module Environmental Adaptability Test – Dry and Hot Weather Conditions” according to China’s different regional climate environment, “CQC3304-2013 Ground Crystalline Silicon Photovoltaic Module Environmental Adaptability Test – Damp Heat Climatic conditions and “CQC3303-2013 ground crystalline silicon photovoltaic modules environmental adaptability test – alpine climate conditions” and other test standards. All of these indicate that the test standards for PV modules are not comprehensive enough to prove the long-term reliability of the components of the components through testing.

2, the certification component is not representative

Third-party testing is expensive, such a high testing cost, which company will casually test out! And which company will randomly pump or send the worst products to third-party testing! This is destined for the company to send products to third-party testing. At the time, you will be very cautious, not only using high-quality materials, high-quality production processes, but also re-selecting in the final product, and finally sending the products that have been screened several times to third-party testing. Of course, the significance of this test is only to obtain a certificate of conformity, then how to guarantee the quality of the company’s products?

3, can not achieve continuous monitoring of product quality

The type inspection, supervision and inspection, supervision and inspection of the third party are very simple, and the inspected party will be notified before the inspection. After receiving the notice, the inspected party will conduct a “concentrated replenishment” in a short period of time; in addition, the photovoltaic industry circle Very small, the inspection agency will also give a “face” during the inspection, so the supervision and inspection by the third party is flawed. Then, everyone will ask, is there no quality control within the company? The answer is yes, every company will “do everything it can” to improve product quality, and this “doing what it can” means making full use of the company’s existing resources. Conduct product quality control. However, in general, there are only a few simple inspection and inspection equipment for production, and there are few equipments that study the structure, performance and service life of photovoltaic modules and materials. All in all, these products are not subject to more comprehensive and continuous quality control.

4, product updates fast, short-lived products become the fish of the net
In recent years, due to the overcapacity of photovoltaics, the entire photovoltaic industry chain has been transformed. Only rapid changes in enterprise products can adapt to changes in the market, and there is a possibility of survival. How to control the quality of products is particularly important in this frequent change. . According to the “61215:2005 Retesting Guidelines”, regardless of changes in the thickness of the silicon wafer, changes in the slurry for the battery, or changes in the backplane and EVA of the components, it is necessary to re-calibrate the corresponding items to ensure product quality. It is impossible to rely on third-party testing for such frequent changes. In addition, the general enterprises themselves do not have systematic testing methods. These inspection vulnerabilities are likely to bring these “revolutionary” unsuccessful photovoltaic products to the market.

5, other reasons
The transportation personnel, installation and use personnel of the components do not understand the products, and do not treat the photovoltaic products according to the standards of the semiconductor industry, resulting in product hidden troubles during transportation and installation. What’s more, some companies conduct malicious bidding for survival, and produce and criticize different products for impersonation. These will lead to uncontrollable quality of photovoltaic products.
