基于欠电压脱扣器的电气联锁设计

万能式断路器在联络系统中起到保护与联络的作用，同时也可作为大容量双电源转换系统的载流执行元件。瞬时欠电压脱扣器和辅助触头均是断路器的常配电气附件，可起到欠电压保护、提供远程信号的作用。在联络系统及双电源转换系统中，通过对附件的有效组合，可起到电气联锁的作用。由于接线简单、不增加零部件，故在运行过程中具有高灵敏度、高可靠度等特点。

Design of the Electrical Interlock Based on Under-Voltage Release

Conventional circuit breaker is the main electrical equipment in contact system,which plays the role of protection and communication.It also can be used as a large-capacity carrier actuator for dual-power conversion system. Instantaneous under-voltage release and auxiliary contacts are electrical accessories for circuit breakers,which play the role of protection and providing remote signals.Through effective combination they can also play the role of electrical interlock in the contact system and dual-power conversion system.Because of the simple wiring and no parts addition,the design has high sensitivity and high reliability characteristics.
