【Abstract】 Circuit breaker is a kind of switch－ appliance uslinged in elect ric power system for cutting－ in and cutting－ off the circuit as well as provi ding protection and controlling on all types of breakdown. Intelligent release i s an important component of the intelligent breaker, which has the ability to pr otect against failures such as overload, short circuit, leak electricity and gro und connection. Moreover , it has the function of display, store, recall, logica l analysis, judgement and selection as well. Adoption of network communication t echnology makes it possible that intelligent power supply system and distributio n system composing by many intelligent breaker and having the "four remote " fun ction. By analyzing system fault, the design principle and working principle of intelligent release and protection principle of multi－ breaker networking are c onfirmed, and the composition of intelligentized technology is confirmed also. T he design of the hardware circuit and the software system is completed in conseq uence .The protection performance is presented and the technological feature of intelligent release is analyzed at the same time in this paper.更多还原
