L.N.PE对应那三个单词的缩写

Live, Neutral, Protective Earth
(Live 读如 Life)

谢谢,有知道了一个东西

翻译成中文是?

火线,零线,保护接地

應該是Line吧!!

随手抄一段

60950標準
Protective systems or devices in PRIMARY CIRCUITS shall be in such a number and located so as to
detect and to interrupt the overcurrent flowing in any possible fault current path (for example,
line-to-line, line-to-neutral, line to protective earth conductor or line to PROTECTIVE BONDING
CONDUCTOR).
請參考

火线又叫活线,是从 live 一字来的,又带电的部件叫 live parts,也是这个意思.L=Live 应该是没错的,当然 line 亦是有人用的.

L=LINE(相线,火线) N=Neutral(负线,零线),
PE=Protective Earth (保护接地)

Live 和 Line (尤其是三相)都有人用就是了
