山东干电工这么卷?叫三个人上门,两个人白等一天?
😊謝謝分享
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
厉害
您好.如果是逆变器交流电零火都带电压!怎么办呢?请求指导
PROFESSIONAL
所以到底怎麼修好的 看完也不明白
應該是漏電保護器本身有問題。
@@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?
其实就是漏保漏电。
@@user-vh8tu2ez5q 怎樣能測出?是零線出入通路所以判斷為漏電嗎?
@@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。
这电笔在哪买?牌子?
@@user-ok1su2pn6j 我拼多多买了一个,二十来块钱吧。
