案例一小王在某小区的一栋新楼房做木工活,突然手电钻不转了,他以为是这个插座的电路没电了,于是就先拔掉插头,但没关闭电钻的开关,将插头插在另一面墙的插座上。当他的手捉着两芯插头(因原三芯插头坏了,后来就改用无接地的、小扁形的二芯插头)插入插座时很难插入,后来,他再用手猛地往里一插,就发生了触电事故。 A case of a small king in a district of a new building to do woodworking, sudden hand drill does not turn, and he thought it was the outlet of the circuit is dead, so first unplug the plug, but did not turn off the drill switch, the plug Plug in another wall socket. When his hand holding the two-pin plug (because the original three-pin plug is broken, then use ungrounded, small flat two-pin plug) is difficult to insert into the socket, and later, he then suddenly inside a hand Plug, there was an electric shock accident.
