摘要
文章通过将隔离断路器与传统断路器、隔离开关进行对比,阐述了隔离断路器的设计理念、结构和技术特点,分析了隔离断路器上隔离开关、接地开关、电子式电流互感器、闭锁系统、在线监测装置的功能集成化情况。并针对隔离断路器隔离功能的特殊型式试验要求,分析了隔离断路器组合功能试验要求与分立的断路器和隔离开关的独立要求之间的差异。
By comparing disconnecting circuit breaker(DCB)with traditional circuit breakers(CB) and open-air disconnectors(DS),this paper introduced the design concept,structural and technical features of DCB.The functional integration of DS,earthing switch(ES),electronic current transformer(ECT),blocking system and on-line monitoring device are analyzed.According to the special requirements of the type test of DCB,this paper introduces DCB's special combination functional requirements and the differences from traditional CB and DS.
