摘要
笔者介绍东莞供电局110 kV线路复合绝缘子防雷保护并联间隙的应用研究成果,对安装并联间隙后线路雷电性能进行计算,对其引导雷电放电、转移疏导工频电弧、均匀工频电场3种功能加以试验验证,并介绍所研制的110 kV线路复合绝缘子防雷保护并联间隙的现场运行情况。研究结果表明,设计的110 kV输电线路复合绝缘子用并联间隙满足要求,现场运行情况良好,能够作为现有防雷措施的有利补充,具有广阔的应用前景。
The application investigation on parallel gap lightning protection device of composite insulators for the 110 kV overhead transmission line used in Dongguan Power Supply Company is present in this article. The lightning performance calculation after the installation of parallel gap device is carried out. The functions of its guiding lightning discharge,transferring power frequency arc,uniforming power frequency electric field are verified by tests. The operation situation of the 110 kV line parallel gap lightning protection of composite insulator is introduced. The results show that the designs of the parallel gap for 110 kV transmission line composite insulators meet the requirements. The parallel gap is in good on-site operation condition, which can be used as the positive complement the existing lightning protection measures, and has broad application prospects.
