在实际工作中,相当一部分电工对低压断路器、低压接触器等设备的维护、检修很重视,而对漏电保护器的维护则形同虚设。然而,实际上,漏电保护器好比医生的听诊器一样,可以正确的发现一些线路故障,提高服务质量,缩短停电时间。在实际工作中,只是由于不正确的整定了漏电保护器动作 In practical work, a considerable number of electricians attach great importance to the maintenance and repair of low-voltage circuit breakers, low-voltage contactors, and other equipment, while the maintenance of leakage protectors is in name only. However, in fact, the leakage protector is like a doctor’s stethoscope, which can correctly find some line faults, improve the service quality, and shorten the power outage time. In actual work, just because of incorrect setting of the leakage protector
