- 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
- Q:Transmission system and distribution system
- Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV
- Q:What are the general requirements for working on distribution equipment?
- Common type cable connector used in power distribution equipment
- Q:What is the role of transmission system and distribution system in power grid
- The power load center is more concentrated in the industrial zone and the big city,
- 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 are the two power distribution equipment?
- Such as generator, transformer, circuit breaker, isolating switch, bus, power cable and transmission lines, etc..
- 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:Main equipment of high voltage direct current transmission
- At present, most of the converter adopts thyristor thyristor rectifier, which is composed of three phase bridge rectifier.
- Q:Difference between distribution voltage and supply voltage
- A distribution within the cell, the high voltage side is 10KV, the low voltage side is 220V or 380V.
- Q:AC distribution equipment including distribution box
- so there will be in the power distribution cabinet a reference line and a zero line selection of single-phase 6A can switch.
