利琦泉1000求解:(电工知识)请问火线、零线、相线、地线分别指什么线?一般是什么颜色? -
屈楠怎17797765754 ______ 火线和相线实际上是相同的线,就是火线是单相电源的叫法,相线是在三相电源中的叫法,这个你用验电笔一试就明白了,他们都能使电笔亮哈,也绝对不能用手去触摸,极度危险了,零线是以前的叫法,在现在普遍采用的供电系统中都是采用三相五线制,其中就有中性线了,这个一般来说也就叫零线了哈,还有一根线就是接地线了,也就是接地保护线,火线一般在单相应用中用红色了,在三相应用中用红绿蓝了,零线可以用黑色了哈,接地保护线就是专门规定的了,黄绿相间的颜色,这个你一定不要搞错了哦,千万不要和零线搞混了,要不你一用电就掉闸(现在多用漏电保护开关哈),要不就会产生危险了.
