摘　　要：针对一起关闭10 kV开关柜门引起的异常跳闸问题,通过操作回路原理分析和抗冲击性能极限试验,发现操作回路中的跳位保持继电器受到强烈冲击时会误动。提出了一种通过调整继电器排布提高操作回路抗冲击性能的方法,为继电保护装置操作回路开发提供参考。This paper introduces an abnormal trip problem caused by closing the door of 10 kV switch cabinet.Through the analysis of the principle of the operating circuit and the ultimate test of the anti-shock performance,it is found that the skip holding relay in the operating circuit will misoperate under strong impact.A method is proposed to improve the anti-impact performance of the operating circuit by adjusting the relay layout,which provides a reference for the development of the operating circuit of relay protection devices.
