摘要
避雷器是一种在电力系统中应用十分广泛的电气元件,主要用于对变电站和输电线路设备进行过电压保护。文章对历史的和现有的避雷器带电测试方法进行了系统地比较,针对生产单位的实际情况对各种方法进行了实用性分析;依据近年来试验技术和仪器制造技术水平的提升,对避雷器带电作业开展的硬件条件进行了设计改造,对电网生产单位的避雷器D类检修策略提出了建议。文章的分析内容和研究结论对于电网生产运行单位制定避雷器检修策略具有较大的参考价值和指导意义。
Arrester as an important electrical component is widely used in electric power system. It is mainly used for over-voltage protection of substation and transmission line equipment. This paper compared the historical and current arrester live testing methods systematically. In view of the actual situation of the operation enterprises,the practicabil- ity of various methods was analyzed. Based on the improvement of the test technology and equipment manufacturing technology level in recent years, the design and modification of hardware conditions of lightning arrester for live work- ing was carried out and the suggestions on class D arrester maintenance strategy for the operation enterprises were puts forward. The conclusion of this analysis and research is of great reference value and guiding significance for lightning arrester maintenance strategy for power grid operation enterprises.
