中国人民电器分析断路器跳闸原理

2021/1/19 14:30:27点击:

家里断路器跳闸一般三个原因,第一是过载,第二是短路,第三是漏电

第一种,过载就是太多的大功率电器同时用超过断路器额定电流了,估计你不会计算,那就少开几个试一试。

第二种,短路可能是某个电器有短路,也可能是暗敷电线短路,不插任何电器试一试如果还跳就要考虑线路有短路,当然如果是带漏电保护开关也有漏电的可能。

第三种,如果是带漏电保护的开关,线路或电器有一点漏电就会跳闸,一般30mA。

如果是第一种情况,那就少开点电器,换大一点的断路器也可以,前提是你的线路不能太细,应该比断路器额定量大。

如果是第二种情况,某个电器部有短路,把这个电器修一修就可以了,如果暗敷线路短路那就一定要请专业人员查清楚。

如果是第三种情况,某个电器漏电,那就一个一个电器逐一插上去开机试一试,到那个跳了就是哪个电器的问题,如果是暗敷线路有漏电,非专业人士是查不出来的,换一个不带漏电保护的开关就行了,只是少一道安全保护。
