摘　　要：当漏电开关N极为常通情况时,在进行剩余电流动作特性带载试验过程中,因现有的检测设备无法精确测出开关分断时间,需要配合其他附加设备进行动作特性分断时间测量。在此测试线路过程中会导致测量结果不准确,也无法更加精确地对更小的漏电电流值进行测量。因此,该文将在原有的测试线路工作原理中进行线路优化。并针对此现象设计一套能够满足检测更小的漏电电流与动作特性分断时间检测平台。使整个检测过程耗时缩短,减少手动测量带来的误差。并实现了对小漏电电流动作特性试验较精确的测量。Aiming at problem that auxiliary equipment needs to be utilized to measure the action break time due to working principle of the existing testing equipment itself, during load action characteristic test of N-pole normal y open leakage switch. The original test circuit is optimized, and a circuit which can satisfy the detections of small leakage current and break time is designed. So that time-consuming of entire detection process is shorten, the error caused by manual measurement is reduced, and accurate detection of smal leakage current is realized.
