Research and Development of Switch-type Fault Current Limiter for High Voltage Power Network

Aiming at the serious problem of power network short circuit current overproof fault in?creasingly, the energy-saving fault current limiter based on large capacity fast switching release (FSR)with explosive fast breaking carrier bridge integrated by fault limiting reactor was developed and ap?plied in 220 kV Ningxia Buqiao transformer substation, furthermore, the 330 kV switch-type no-lossfault current limiter based on high-speed large-capacity vacuum breaker technology and short-cir?cuit current fast recognition technology and split-phase control technology was developed and carriedout 2 field experiments in 330 kV Ningxia Yingan line I successfully. Field operation and experimentsshow that The 2 switch-type high-voltage fault current limiters solves the key problems of the safety,reliability and economy in the power network fault current limiter practicality fundamentally, whichmark a breakthrough on fault current limiter technology.
