摘要
传统输电线路绝缘子需要并联避雷器,虽然保证绝缘子免受雷电过电压造成的闪络损伤,却加重了线路载荷、增加了线路复杂性以及检修难度。针对上述问题笔者研究并实现了一种具有绝缘子性能的避雷器,并通过电场计算、机械受力以及电气试验等分析了设备的性能,以及在承德供电公司宝寿线挂网试运行论证了此设备在简化线路设施、便捷线路检修以及保证电网安全稳定运行的优势。
Traditional transmission lines, which prevent the insulator from flashover lightning overvoltage zuu^u by injury, need insulator and lightning arrester parallel connection. But increased line load, increase circuit complexity and maintenande difficulty. In this study, a surge arrester with the performance of insulator was developed, and its characteristics were analyzed through calculation of electric field, analysis of mechanical forces, and electric test. Trial operation in Bao-Shou power transmission line verifies that this surge arrester can simplify the line＇ s facilities, facilitate the maintenance, and ensure safe and stable operation of the power grid.
