- 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 role of transmission system and distribution system in power grid
- Such as water resources are concentrated in the river basin water level drop larger place, fuel resources in coal, oil, gas.
- 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: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: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:AC distribution equipment including distribution box
- Connect the power supply, transformer, converter and other equipment for load distribution box, and monitoring
- 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:What is the transmission line, what is the power distribution equipment
- Usually an overhead line, a very small number of lines (or some of them) is a cable line
- Q:Transmission system and distribution system
- Simply put, you can distinguish between the end of the cable to the use of electrical equipment (motor, power box) is the distribution system to the substation, transformer is the transmission system
- 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
