断路器分合闸线圈基本性能检测拓扑设计

The Basic Performance Detection Topology Design of Circuit Breaker Sub-closing Coil

断路器分合闸线圈是断路器的核心部件之一。近年来,频繁发生因断路器分合闸线圈烧毁而造成的短路事故扩大。分合闸线圈能否正常的工作,关系到断路器能否可靠稳定的动作。但是,对于断路器线圈关键性能的检测,目前缺少统一且标准的检测方法。因此,在分析断路器结构和工作原路的基础上,分别设计了针对断路器分合闸时间和出力大小的检测拓扑,可以有效检测出断路器分合闸线圈两个关键性能的状况,这对断路器可靠稳定动作有着十分重要的意义。

The opening and closing coil is one of the core components of the circuit breaker. In recent years,the shor t circuit accident caused by burned coils has frequently expanded. The normal operation of the closing and closing coils is related to the reliable and stable operation of the circuit breaker. However,as for the detection of the critical performance for the circuit breaker coil,there is currently a lack of a unified and standard detection method. Based on the analysis of the circuit breaker structure and the original working path,this paper designs the detection topology for opening and closing time and the force of the circuit breaker,respectively. It can effectively detect the two critical performances of the breaker＇s opening and closing coils,which is of great significance to the reliable and stable operation of the circuit breaker.
