TN 系统的接地故障的保护

摘要

通过示例分析了接地故障造成危害的原因，提出了安装剩余电流保护器以切断电源以及设置等电位联结以降低接触电压两种保护措施，指出在设计过程中应配合使用各种保护措施，以防止接地故障带来的危害。%This paper analyzed the dangerous reasons caused by grounding faults through example,proposed installation of residual current pro-tector to cut off the power and setting of equip-potential connection to reduce the contact voltage two kinds of protective measures,pointed out that should use of various protective measures in design process,in order to prevent the harms caused by node failure.
