摘要
针对1 000 kV特高压变电站绝缘子串采用瓷绝缘子片具有片数多、结构长、重量大及运维工作量大的缺点,对合成绝缘子在1 000 kV特高压变电站悬垂绝缘子串中的应用进行分析。基于已有运行经验,给出了1 000 kV合成悬垂绝缘子串的组串方案,经分析,采用合成悬垂绝缘子串可节省变电站构架投资,具有一定的技术经济性。
Aiming at shortcomings of insulator strings using porcelain insulator in 1 000 kV UHV substations, such as a large amount of pieces, long structure, large weight and too much operation and maintenance work, the application of composite insulators in suspension insulator strings is analyzed in 1 000 kV UHV substations. Based on the present operating experience, an assembly, drawing of 1 000 kV composite suspension insulators is proposed in the paper. The analysis shows that the application of composite suspension insulators can save the substation structure investment and has certain technology ancl economy.
