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?: When the high voltage line is not cut off, the person in charge of the work shall explain to the whole staff that there is electricity on the line and strengthen the monitoring

Q: DC transmission equipment: DC screen commonly known as intelligent maintenance free DC power supply screen, referred to as DC screen, the general model is GZDW.

Q: Are electric wires and cables belong to distribution equipment?: Distribution equipment (Electrical Equipment) is in the electric power system of HV switchgear, generator, transformer, power circuit, circuit breaker, low voltage switch cabinet, distribution board, switch box, control box and other equipment collectively.

Q: Distribution system equipment classification: Mechanical equipment is made up of mechanism, power mechanism, transmission mechanism, actuator and control system

Q: An introduction to the interpretation of flexible AC transmission systems: The series compensation device such as thyristor controlled series capacitor (TCSC), thyristor controlled reactor (TCSR), static synchronous series compensator (SSSC), active power flow is mainly used to change the system of distribution, improve the system transmission capacity and transient stability etc.;

Q: Main equipment of high voltage direct current transmission: It is composed of two or more converter bridges, which can realize the AC DC AC converter.

Q: Transmission and transformation equipment: Because of the need to change the current in the process of transmission, so the current transfer is called power transmission.

Q: Power distribution equipment should be prepared before the blackout?: The actual operation, one man operation, another voice.

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
