Abstract:
Series of intelligent relays are applied in China Advanced Research Reactor(CARR)medium voltage power supply system to improve the reliability,safety and intelligence of this system.The constitution,performance,characteristics and function of intelligent relays are also expatiated in this paper.CARR medium voltage power supply system realizes the digitalization monitoring of power supply system,and the transducers,cables and protective relay device can be eliminated,to assure the economy,reliability and advance of the whole medium voltage power supply system.
