当人体和带电的电线或设备等接触时,电流就会从人体中通过而造成触电。但是,当人体靠近较高电压(3,300伏以上)的带电电线或设备时.虽末直接接触,由于电弧放电也会造成触电。人体触电。一般可分为单相触电、两相触电和跨步电压触电三种。一、单相触电如果触电者接触一根带电的电线。电流从一根电线通过人体流入大 When the body comes into contact with live wires or equipment, electric current can pass through the body and cause an electric shock. However, when the human body approaches charged electric lines or equipment at a higher voltage (3,300 volts or more), electric shock may be caused by arcing even though the end is in direct contact. Human body electric shock. Generally can be divided into single-phase electric shock, two-phase electric shock and voltage step-by-step three. A single-phase electric shock If the electric shock contact with a live wire. Current flows from a single wire through the human body
