- 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:What are the general requirements for working on distribution equipment?
- Common type cable connector used in power distribution equipment
- Q:Transmission lines are not electrical equipment?
- Transmission lines are not electrical equipment? The answer is: the device is a function of the assembly
- Q:What is the power equipment in the distribution room?
- High voltage distribution room generally refers to the 6kV - 10kV high voltage switch room; low voltage distribution room is generally refers to the 10kV or 35kV station with variable line 400V distribution room
- 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: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: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:AC distribution equipment including distribution box
- protection of the power supply system is between the power supply and the load are connected, disconnected, conversion
- 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:Power distribution equipment should be prepared before the blackout?
- after the high and low voltage power failure, the work must be carried out before the first inspection
