摘要
四联耐张绝缘子串是上海地区500 kV线路中较普遍采用的形式,500 kV线路四联耐张串结构复杂,四分裂导线组合张力相当大,带电更换四联耐张绝缘子串难度大、工器具要求高,同时需充分考虑带电作业时500 kV线路安全距离,就带电更换500 kV线路四联耐张整串绝缘子的方案进行了分析与探讨。
The strain four-string insulator sets are widely used in 500 kV lines in Shanghai. Since the strain four-string insulator set for 500 kV lines is complex in structure and the combined tension of the four-bundled conductor is too large, the live line replacement of the insulator set is difficult and the requirements for the tools are also high. At the same time, the safety distance of the 500 kV lines should also be considered. The scheme of live line replacement of the strain four-string insulator set for 500 kV lines is discussed.
