摘　　要：阐述了电击防护的两个重要措施。对重复接地和等电位联结在工程中的作用和效果进行分析。通过理论计算,定量分析了等电位联结减小人体预期接触电压的效果远优于重复接地,没有必要花费大量的人力物力设置人工重复接地。Two important protective measures against electric shock are described.The function and effect of repeated grounding and equipotential bonding in engineering are analyzed.Through theoretical calculation,the effect of equipotential bonding on reducing the expected contact voltage of human body is much better than repeated grounding is quantitatively analyzed,not necessary to spend a lot of manpower and material resources to set up manual repeated grounding.
