剩余电压是指用插头连接的电器 ,当拔掉电源插头的瞬时 ,插头上各插脚之间的残余电压 ;或是当断开电气设备电网供电的瞬时 ,内部贮能元件 (如电容器 )上的残余电压。此时人如果触到插头或贮能元件就有触电的危险。许多有关电气设备的国家标准条款中都从不同角度定量地提出了剩
Remaining voltage is the electrical appliance connected by the plug, the residual voltage between the pins on the plug when the plug is unplugged, or the voltage on the internal energy storage element (such as a capacitor) when the power supply of the electrical equipment is disconnected Residual voltage. At this point, if people touch the plug or energy storage element there is the danger of electric shock. Many of the national standards for electrical equipment have been quantitatively proposed from different perspectives
