1 事故经过 1999年6月,我村张某办的缝纫培训班里的空气开关跳了闸,张某没找电工。就自己查找跳闸原因。检查发现缝纫机电机进线不好,就去接线。刚一摸到电线,就被电击倒在地上,手掌当即被电击了两个洞,要不是距医院近抢救及时,差点丢了性命。 2 事故原因 2.1 为什么空气开关跳了闸还会有电呢?经检查发现,是缝纫机电机进线绝缘层磨破造成短路,空气开关跳闸,强大的短路电流使空气开关其中的—相动静触头严重烧结粘连在一起,外观看似跳闸,实际上有一相并没有断开,由于无法观察空气开关内部情况,张某认为宁气开关跳了闸没电,就去接线,结果造成触电。
1 accident After June 1999, my village Zhang Office sewing training classes in the air switch jumped gate, Zhang did not find electrician. Find your own trip reason. Check the sewing machine motor into the line is not good, go to the wiring. Just touch the wire, it was electric shock fell to the ground, the palm was immediately electric shock two holes, or rescue from the hospital in time for the near, almost lost his life. 2 Causes of the accident 2.1 Why the air switch to jump the gate will have electricity? The inspection found that the sewing machine motor line insulation caused by wear and tear short circuit, the air switch tripping, a strong short-circuit current so that the air switch which phase-static contact Serious adhesion with the sintering together, the appearance of seemingly tripping, in fact, there is a phase did not disconnect, due to the inability to observe the internal conditions of the air switch, Zhang think Ning switch does not switch off the gate, went to the wiring, resulting in electric shock.
