这种车床漏电一般多见于导轨下方的电线破损，而视频里车床需要用到冷却液，所以遇水跳闸

所以到底怎麼修好的 看完也不明白

[@wenfeng1000]

應該是漏電保護器本身有問題。

[@hongmander]

@@wenfeng1000 That's what I thought too after few tests, but still need to do all tests to get paid. Right ! 😁😁

是不是换了个漏保就好了？

[@user-vh8tu2ez5q]

其实就是漏保漏电。

[@andrewchan7472]

​@@user-vh8tu2ez5q 怎樣能測出？是零線出入通路所以判斷為漏電嗎？

[@user-vh8tu2ez5q]

@@andrewchan7472 不是的，1P+N的漏保零线有常通的，也有手动脱扣会断开的，但是零线不带保护和灭弧。他这个主要是漏保零火之间电阻不正常，正常应该是无穷大。
