摘　　要：保护接地系统的应用,可以实现对低压电气装置的有效保护,从而降低设备故障率,保障设备及人员安全。保护接地系统在运行原理和结构上具有一定的复杂性,因此在应用过程中应该进行针对性设计,改善系统运行性能,应对电力生产中的突发性状况。主要对低压电气装置保护接地系统进行介绍,分析需要保护接地和不需要保护接地的低压电气装置范围,明确低压电气装置保护接地系统的问题及解决措施。The application of the protective grounding system can realize effective protection of low-voltage electrical installations,thereby reducing the failure rate of equipment and ensuring the safety of equipment and personnel.The protective grounding system has a certain degree of complexity in the operating principle and structure,so it should be designed specifically in the application process to improve the system’s operating performance and deal with unexpected situations in power production.This article will introduce the protective grounding system of low-voltage electrical installations,analyze the scope of low-voltage electrical installations that require and do not require protective grounding,and clarify the problems and solutions of the protective grounding system of low-voltage electrical installations.
