摘要
介绍了小功率电动机接地装置安全电阻的限值问题,对人体的安全电压、电流及系统的接地电阻限值、接地电阻阻值的不同对人体所造成的危害进行了分析,得出电机内部接地电阻过大对人体具有较大的触电危害。
The safe resistance limit for small - power motor grounding is introduced .By analysing the safe voltage,current and grounding resistance limit as well as the harmness degrees of different grounding resistance on human body, it is concluded that larger internal grounding resistance of motor would result in shock.
