一起电源异常引起的继电器抖动事件分析

Analysis of a Relay Jitter Event Caused by Abnormal Power Supply

结合一起交流电源整流后引起跳合闸回路继电器抖动“呜呜”响的事件展开分析,通过对跳合闸回路的原理进行分析,然后反复测试,找到了事件发生的根源,并提出合理的解决方案。

An event that causes the jitter"whine"sound of relay in tripping and closing circuit after AC power supply rectification is analyzed.By analyzing the principle of tripping and closing circuit,and then repeatedly testing,the root cause of the event is found,and a reasonable solution is put forward.
