摘　　要：对柱上永磁机构真空断路器控制器的电源系统进行了研究,给出了电源系统中电源切换、电容器电压监测、IGBT全桥驱动等功能模块的实现方法。通过微控制单元(MCU)的I/O口发出的脉冲来控制IGBT导通时间,从而控制分合闸线圈通电时间,以此完成分合闸操作。对分合闸线圈的电流波形进行分析,通过实验测试确定可靠的分合闸脉冲时间。实验结果表明:采用所设计的电源后,柱上永磁机构真空断路器的可靠分闸脉冲时间为20 ms、合闸脉冲时间为40 ms,在保证动作成功率的同时有效地缩短了分闸时间和合闸时间。The power supply system for the controller of pole-mounted circuit breaker with permanent magnetic actuator is studied and the implementation methods of its functional modules are given,such as source switching,capacitor voltage monitoring,IGBT full-bridge driving,etc. The MCU （MieroController Unit） sends the pulse via its I/O port to control the IGBT conducting time of the open/close coil to realize the open/close operation. The current waveforms of open/close coil are analyzed and the reliable open or close pulse width is determined by experiments. Results show that,with the designed power supply,the reliable open and close pulse widths for the pole-mounted circuit breaker with permanent magnetic actuator are 20 ms and 40 ms respectively,which are effectively shortened while the operation success rate is guaranteed.
