The key technology of SF6 circuit breaker for switching capacitor banks
2018 International Conference on Advanced Mechatronic Systems (ICAMechS)(2018)
摘要
The paper contains a wealth of experimental experience of the SF
6
circuit breaker switching capacitive current, the common problems in the test are summarized. Through theoretical Research and Simulation Analysis, find out the key Technology that affects the switching Capacitor Bank, such as sparking phenomenon of main contacts, the pre/re-striking between the main contacts, the punctures in the nozzle. Put forward specific measures to improve the circuit breaker capacitor bank switching performance, further enhance the transmission reliability of UHV power grid.
