摘要(Abstract):
为了节约架空输电线路走廊距离,复合绝缘横担技术开始发展起来,近些年来在110 kV和220 kV等电压等级的架空输电线路中屡次应用。介绍了国内首基500 kV可踩踏复合绝缘横担塔基本情况,对其在线路上安装时的组装方式进行了分析,并根据其在500 kV超高压交流架空输电线路上运行一年多以来的情况,进行了总结和展望。
In order to save the corridor distance of overhead transmission lines, the composite insulation cross-arm technology was developed and has been repeatedly applied in 110 kV and 220 kV overhead transmission lines. The paper introduces the first 500 kV stepping composite insulated cross-arm tower and analyzes the method of its assembly on overhead transmission lines; based on the operation on 500 kV EHV overhead AC transmission lines, it makes conclusions and presents a prospect.
