家用电器产生带电的原因,通常有三种:一、电器带电部分和外壳之间的绝缘被击穿或严重损坏。人体碰到壳体有强烈的电击感,往往不能自我控制脱离。二、电器的绝缘性能不良。这种情况下,人体触及壳体有“麻手”的感觉,但能自我摆脱。三、电器本身的分布电容和绝缘电阻引起的对地电 Household appliances have charged, there are usually three: First, the electrical parts of the insulation between the shell and the breakdown or serious damage. Human body hit the shell has a strong sense of electric shock, often can not self-control from. Second, the electrical insulation of poor performance. In this case, the human body touches the shell with the feeling of “hemp”, but can get rid of himself. Third, the distribution of electrical capacitance and insulation resistance caused by the electricity
