摘要
由于投运时间较长,原线路设计标准较低,部分110kV线路的对地距离、对交叉跨越距离严重不足,致使其安全稳定运行受到很大威胁。在110kV线路中,采用绝缘横担替代原钢质横担,提高了对地和对交叉跨越物的安全距离,增强了架空输电线路的安全、可靠性,达到了降低线路改造成本的目的。
Due to put into service for a long time, there is distance to the ground and to stride cross objects much less than the design standard in partial 110 kV transmission line, threatens the safe and steady operation of the transmission line. Using insulation crossarm substitutes for steel crossarm on the 110 kV transmission line tower, improves the safe distance of the crossarm to ground and to stride cross objects, reaches the aim of improving the safe and reliability of the overhead transmission line, decreases the cost of the transmission line reconstruction.
