重复接地与等电位联结对降低电击造成人身伤害的效果对比分析

Comparative analysis of the effect of repeated grounding and equipotential connection on reducing personal injury caused by electric shock

以常见的住宅配电为例,通过计算各接地故障回路的接触电压值,以及通过人体的电流实际值,再转化为等效路径电流,并将电流对人体的生理效应作对比,总结各种电击防护措施的应用效果,从而提高从业人员对等电位联结的重视程度。

Taking common residential power distribution as an example,by calculating the contact voltage value of each grounding fault loop and the actual value of the current passing through the human body,and then converting it into the equivalent path current,the physiological effect of the current on the human body is compared,and the application effect of various electric shock protection measures is summarized,so as to increase the attention of practitioners to the equivalent potential connection.
