空气开关总是跳闸,该怎么处理?

  空气开关总是跳闸,该怎么处理?

  1、如果是装了漏保的,漏保跳闸了,说明是线路上有漏电了引起的。比如楼道总开关到各屋分路开关的线路漏电了,或者某户漏电了,但是他屋子漏保失效了,这样直接在总漏保地方体现出来。还有一种情况,户内漏保是30毫安,而总漏保一般规格比较大,比如50毫安,如果出现3户内漏电,而漏电流平均只有20毫安,这样总的漏电流加起来,也超过了50毫安了,造成了总漏保跳闸,而户内漏保没有达到跳闸标准的情况发生。

  2、如果只有空气开关,是新装的,可能是空气开关容量过小了,几个户同时使用大功率电器,临界接近户内开关的保护值但是没有超过,这样造成总电流超过了空气开关保护电流引起过载跳闸,可以换大一号的空开试试。

  3、如果是老线路,开关用了很多年,估计是开关老化了,或者里边有元件过于灵敏引起的误动作,任何电器产品都有使用寿命的,这种情况更换一个就好了。

  4、楼道总开关到户内开外的线路上绝缘不好,或者老化了,引起短路造成的空气开关跳闸,这种情况是无法合闸的,一定要彻底清查出来短路的问题。

  5、开关进出线,可能存在接触不良,或者严重氧化了,直接发热导致空气开关保护了,需要重新把氧化的线头去掉,加上线耳,重新拧紧螺丝。
