circuit.

- With specialized voltage arrester for PV. And both positive and negative pole

have function of lightning protection.

- Use four-pole breaker series connected by postitive and negative pole

separately to enhance DC withstanding voltage value.

- Monitor current as far as input array and display the value by RS485.

- Monitor voltage after combination, and display the value by RS485.

Q:What are the customer groups faced by power intelligent equipment?Products such as electric capacitor reactive power control (capacitor module), reactive power compensation controller, the series of electric power meter, active filtering equipment, power monitoring system, energy management system, operating system and DC power system accessory products.: Power capacitor is a kind of reactive power compensation device. Power system load and power supply equipment such as motors, transformers, transformers, etc., in addition to the consumption of active power, but also to absorb reactive power. If the reactive power is supplied by the generator, it will affect its active power output, not only uneconomical, but also lead to poor quality of the voltage, affecting the user's use.

Q:In order to obtain the qualification test of power equipment, the company needs to have a hard condition: The office, factory are required not less than the number of square and so on, the registered capital of the company scale is also in short, very troublesome, a pile of data. To prepare documents and construction safety license corresponding to the handle. In a word, money, have a lot of money money is easy,

Q:What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!: The necessity of power equipment testingPower equipment is the hub and channel in the transmission and distribution network, in the course of the use of equipment will be aging, disrepair, hidden trouble, etc.. However, these situations can not be ruled out by the eyes of the people, the staff of the experience, it is necessary to detect the special power equipment to check out these security risks and the organization of human resources in a timely manner to exclude.In the operation of electric power, the safety of electric power has always been a chord of the electric power. Power equipment testing is actually played a role in prevention and detection of hidden dangers. So it is very important to detect the electric equipment (i.e., the preventive test of electric equipment).

Q:Power test equipment sales to find power supply company which departments? Which departments of the power supply company will use the power test equipment?: The need to find a maintenance work area (a place called SF6, fix test area) switch belongs to them

Q:Is the GIS in the electric power high voltage switch cabinet: High voltage electrical (mainly above 35kV) exposed to the air, common substation circuit breaker, isolating switch, bus, phases, equipment, and equipment between between and so must have a relatively large safety distance. This area is relatively large, but also exposed to the outside of the security risks are more. GIS is a kind of technology, the bus CircuitBreakers isolating switch for high-voltage electric appliances shell pack, seal filled with six sulfur hexafluoride gas, according to the elements of seal, not a whole big box, such as every bus from the outside is a large cylinder etc.. This equipment can be very compact layout, and a sealed shell, but also more secure.High voltage switchgear is only a device installed in a cabinet, and this is generally high voltage 10kV, up to 35kV, and then there is no general high switch cabinet this form. Of course, you can also use GIS technology. But generally speaking, GIS is more than 110kV GIS switch station.You can Baidu image search GIS switch station". You can see that the big cylinder together is the GIS switch equipment, large cylinder which is the bus, circuit breakers and other equipment, see pictures more intuitive.

Q:In what way is it confirmed that the destroyer is an electrical device? Identification or what.: Not yet installed agricultural low-voltage lighting circuit, not in the use of electrical equipment. Even if the person who took part in the erection of the wire, it will not cause harm to public safety, its behavior should be qualitative theft.

Q:The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!: According to the line voltage, the neutral grounding is star type connection, line voltage is 3 times the square root of the phase voltage, so the choice of C

Q:Electric power equipment start-up and commissioning of the project there is a difference?: After a single commissioning, and then linkage test, after the test, such as no-load, put into operation in the above steps are completed, the test is no problem, start running with load.

Q:Electrical equipment classification: Electric power system in a lot of power equipment, according to their role in the operation of different, usually divided into electrical equipment and electrical equipment two times. Directly involved in the production, transformation, transmission, distribution and consumption of electrical equipment called electrical equipment

Q:What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.: The double name of equipment refers to the name and number of the equipment.The name of the equipment is Chinese, the number is Arabia. Together is a double name. The same station, will not appear the same name, or the same number, is the only. The only combination of the two can be more accurate.
