一般说来,人体触电有两种形式:一种是在日常生活中自行安装、修理电气设备时,人体直接触及到电压为220伏以上的带电体,电流通过人体而伤害其内部器官,如心脏、呼吸系统、神经系统等。这种触电我们称它为“电击”。另一种是人体接近高压带电体时,只要达到一定的距离,人体与带电体之间就会发生电弧放电,使人体皮肤烧伤,有时可深达肌肉、骨胳,甚至引起骨折及坏死。这样的触电形式我们称它为“电伤”。在实际生活中,多数情况是由于“电击”而造成死亡的。“电击”对人体的伤害程度,与触电电流的大小、触电时间与以及触电是交流电还是直流电有关。如果人体触及到交流电,这时只要触电电流达到0.4毫
In general, there are two forms of electric shock to the human body. One is that in the daily life, when the electric equipment is installed and repaired by oneself, the human body directly touches the charged body with a voltage of 220 volts or more. Current flows through the human body to injure the internal organs such as the heart , Respiratory system, nervous system and so on. This kind of electric shock we call it “electric shock”. The other is the body close to high-voltage charged body, as long as a certain distance, the body and charged body will occur between the arc discharge, the skin burns, and sometimes deep muscles, bones, and even cause fractures and necrosis. This form of electric shock we call it “electric injury”. In real life, the majority of deaths are caused by “electric shocks”. “Shock ” The extent of harm to the human body, and the size of the electric shock current, electric shock time and the electric shock is AC or DC. If the human body touches the AC, then as long as the electric shock current reaches 0.4 milliliters
