摘　　要：为适应塑壳断路器体积越来越小型化、功能越来越集成化,设计了一种简单的自带稳压检测、脉宽可控的交直流分励脱扣器模块。分励脱扣器模块的动作机构借用塑壳断路器内部的电子脱扣器,分励模块既可以保持长期在电状态,又不影响电子式塑壳断路器内部的线圈控制电路。In order to adapt to the more and more small size and integrated function of molded case circuit breaker,a new simple AC/DC shunt trip module with stable voltage detection and controllable pulse width was designed.The action mechanism of shunt trip module borrows the electronic release in the molded case circuit breaker.The shunt trip module can keep in the electric state for a long time without affecting the coil control circuit in the electronic molded case circuit breaker.

关 键 词：分励脱扣器 控制电路 稳压检测 脉宽调控
