今年夏天,我厂一位职工发现家里的日光灯关灯后灯管两端仍有微光,用手触摸灯管外壁微光增强。经检查,拉线开关控制的是零线。为了省事,他把配电盘闸刀开关下的相线与零线对调,上述现象排除了。可是过了一会儿,隔壁邻居在移动落地电扇时,突然触电倒地,幸好电扇倒向了另一侧,使触电者脱离了电源,才未发生死亡事故。后来一检查,该电扇的保护零线在调线后成了相线,使电扇外壳带电。
This summer, a worker of our factory found that the fluorescent lamp in the house turned off and the lamp was still glimmering at both ends of the lamp. After checking, pull switch control is the zero line. In order to save trouble, he switch the switch panel under the switch line and zero line, the above phenomenon is ruled out. However, a moment later, when a neighboring neighbor moved the floor-standing electric fan, he suddenly touched down with electricity. Fortunately, the electric fan turned to the other side, leaving the electric shocker out of power without any fatal accident. Later, a check, the fan’s zero line protection after the transfer line has become a phase, the fan shell charged.
