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-loss fault 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 carried out 2 field experiments in 330 kV Ningxia Yingan line I successfully. Field operation and experiments show 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, which mark a breakthrough on fault current limiter technology.
