超高压输电线路采用绝缘架空地线的节能意义和可行性

Energy Saving and the Feasibility of Insulated Overhead Ground Wire on Ultra high Transmission Lines

阐述了２２０ｋＶ及以上输电线路采用绝缘架空地线，每年减少架空地线电能损耗约２ＴＷ·ｈ，可降低功率损耗９９％；并论证了这项技术的可行性及应采取的技术措施；重点介绍了绝缘架空地线保护间隙的型式、技术条件和试验方法。

This paper describes about 2 TW·h electric energy or 99% of line losses were saved each year on transmission lines of 220 kV and above by using insulated overhead ground wires, it also discusses the feasibility and measures being taken for this techniques such as the type of protective gap, technical conditions and test method for insulated overhead ground wire.
