Q: What are the distribution network equipment: suburbs, towns and rural areas, further allocation and supply industry, agriculture, commerce, industry and residents with special needs for electricity secto

Q: What are the general requirements for working on distribution equipment?: Distribution equipment including high voltage power distribution room, substation, power distribution transformer platform, low voltage power distribution room (box), ring network cabinet, cable branch box] outage maintenance,

Q: Transmission system and distribution system: Transmission system is based on the power supply to the same level or lower substation for the purpose of the general voltage level higher (35KV or more)

Q: An introduction to the interpretation of flexible AC transmission systems: The parallel compensation device, such as static var compensator (SVC), thyristor controlled braking resistor (TCBR), static

Q: Main equipment of high voltage direct current transmission: Converter also known as converter valve is the key equipment in the converter station, its function is to achieve rectification and inverter

Q: Rural high voltage transmission line equipment ownership: You do not want to what the transformer behind the high-voltage line,

Q: Transmission and transformation equipment: High voltage has a very high risk, and the target electrical appliances do not need such a high voltage, which needs to reduce the voltage through the transformer

Q: Difference between distribution voltage and supply voltage: Supply voltage refers to the supply point of the line voltage or phase voltage.

Q: Power distribution equipment should be prepared before the blackout?: Before the power failure, the person in charge or the electrical appliance technician should fill in the work order.

Q: CHINT group in the transmission and distribution equipment to do it?: The national grid is not purchasing some equipment of CHINT, CHINT group is now very powerful
