摘要
地下变电站内电缆终端渗水是目前电缆线路运行中比较严重的缺陷之一,而且近几年问题日趋严重。分析了电缆终端渗水的原因,讨论了上海市电力公司检修公司多年来对电缆终端渗水处理的常用方法及其利弊,提出了防治的综合封堵方案,并详细介绍了该方案的施工步骤。在上海地区电缆线路的运行实践,证明了该方案的有效性。
The water penetration of cable terminal set in the underground substation is one of the serious defect in the cable operation presently, and recently becomes serious gradually. The causes of the water penetration are analyzed. The ordinary methods used in Maintenance Company, SMEPC for many years are discussed, together with their advantages and disadvantages. The comprehensive sealing scheme to prevent the penetra- tion is presented, as well as its construction procedure in detail. Its application in cable lines in Shanghai has proven the effectiveness of this scheme.
