我曾遇到这样一件事:停了电的分路照明线路上,出现带电现象。 村民永习家因做家俱,使用电刨子时将本来就不算粗的导线,从电表集表箱出线端烧断一根。唤我去接线,当我爬上木梯开箱拉开电源闸刀正要拆线头,他想把断了的那根下垂线递给我,手刚触到线头,只听他一声“有电”,手就缩回去了。当时我心里还有点好笑说:“你出什么洋相?电源已经拉掉了。”他急忙又说:“真的有电!”看他那一本正经的焦急样子,我也不敢怠慢,立即停止工作,用万能表测量线路对地电压,电表指示值超过200伏。 空线路导线上的电是从哪来的呢?我从头到尾把集表箱线路检查了一遍,也未发现什么问题。但是,停电的导线上确实有电。经验告诉我,这电可能是从本箱用户家串来的外箱线路电源。为了弄明白,经逐户测验,测到朝习的进户线有电压,顺线继续查找,有一 I have encountered such a thing: the shunted electric shunt lighting lines, the phenomenon of electrification. The villagers never learn from home because of furniture, the use of electric planing will not be thick when the wire, from the meter set box outlet end of a broken. Call me to take the wiring, when I climb the ladder to open the power knife is about to demolish the thread, he would like to put that broken thread hanging down to me, just touch the thread, just listen to him “there is electricity ”The hand is retracted. At that time I was still a little funny in my heart and said: “What is your appearance? Power has been pulled out.” He was quickly added: “Really electric!” Look at his serious look anxious, I did not neglect to immediately stop working , With a multimeter to measure line voltage on the ground, the meter indicates more than 200 volts. Where do the wires on the empty wire come from? I checked the meter box all the way through, and I did not find any problems. However, there is power on the power cut wire. Experience tells me that this electricity may be from the user’s home string to the outer box line power. In order to make it clear, by household test, measured into the habitat line has a voltage, continue to find the line, there is a
