摘 要:针对以往分励脱扣器控制电路存在的不足,设计了一种简单的且符合国标要求的新的交直流分励脱扣器控制电路,介绍了各模块功能,并给出了最低成本控制电路图。仿真实验表明,该控制电路仅用14个元件,完成了可预置电磁铁动作时间,可长通电的分励脱扣控制。

Abstract: Aiming at insufficiency of control circuit for shunt release, this paper designed a simple new AC/DC shunt release control circuit in conformity with national standard requirements, introduced each module function of the control circuit and gave the lowest cost control circuit diagram. Simulation experiment shows that the control circuit only uses 14 elements to accomplish pre-setting electromagnetic iron action time, with long time power on shunt release control.
Key words: shunt release; control circuit; lowest cost; long time power on
