摘　　要：电力系统为我国社会经济的发展提供重要的电力支持,电力系统的安全稳定有效保证了我国生产、生活的电力需要,因此必须高度重视电力系统的安全性、稳定性.电力系统由多个设备系统组成,包括用电、配电、变电、输电和发电设备.电力系统的安全可靠运行需要每个设备环节的共同配合.为防止雷电对电力系统造成破坏,必须运用避雷器,因此,探究避雷器消除雷电对电压的影响尤为重要.在基于实际相角法的基础上,试验分析了避雷器现场带电测试应用情况,运用新型方法来测试避雷器的性能情况,特别是检测其阻性和泄漏电流的情况,通过测试来发现避雷器的缺陷,并验证相应解决办法的可行性,以期为工程建设提供一定的理论依据.The power system provides important power support for my country’s social and economic development.The safety and stability of the power system effectively guarantees the power needs of production and life in my country.Therefore,we must pay great attention to the safety and stability of the power system.The power system is composed of multiple equipment systems,including electricity,power distribution,substation,power transmission and power generation equipment.The safe and reliable operation of the power system requires the cooperation of every equipment link.In order to prevent the damage to the power system caused by lightning,it is necessary to use a lightning arrester.Therefore,it is particularly important to explore the lightning arrester to eliminate the impact of lightning on the voltage.Based on the actual phase angle method,the test analysis of the application of the lightning arrester on-site live test is carried out,and a new method is used to test The performance of the arrester,especially its resistance and leakage current,through testing to fi nd the defects of the arrester,and verify the feasibility of the corresponding solutions,in order to provide a certain theoretical basis for engineering construction.
