1.事故情况 1993年7月12日,一吊车工到设备科领工资时,感到太闷,于是开窗透气,当手触及钢窗的推杆时,发觉有电。于是我用验电笔测试,发觉电笔很亮,与测试相线亮度差不多。这引起我的重视,改用万用表交流电压档测量钢窗与中性线之间的压降,结果为116V。用毫安档测时,为105mA。这个电流数值是非常危险的。查资料表明,人体通过工频电流超过20～50mA时,组织细胞受到破坏,控制心脏和呼吸器管的中枢神经会麻痹,造成
1. Accident Case On July 12, 1993, a crane operator was too bored when it came to receiving wages in the equipment section. So he was able to open the window and breathe. When he touched the push rod of the steel window he found that there was electricity. So I use the test pen test, found that the pen is very bright, almost identical with the test line brightness. This caused my attention, switch to multi-use AC voltage file to measure the pressure drop between the steel window and neutral, the result is 116V. Measured in milliamps, 105mA. This current value is very dangerous. Check the information shows that the human body through the power frequency current exceeds 20 ~ 50mA, the tissue cells are damaged, the control of the heart and respiratory tube of the central nervous paralysis, resulting
