摘　　要：描述了万能式断路器用欠电压脱扣器增大脱扣力的设计方法。设计中将正弦交流电整流为脉动电压,有效地避免了欠电压脱扣器的振动。利用有限元分析软件,对电磁力进行了仿真分析,结果证明能有效地增大脱扣力,满足脱扣器的设计要求。This article described the common technique of under-voltage release in conventional circuit breaker. In design the sinusoidal AC power was rectified for the pulsing voltage, which can effectively avoid the vibration of under-voltage release. With Ansys finite element analysis software, it optimized and analysed the electromagnetic force, which can reach the aim of increasing release force.
