摘要
目前国内变电站户外母线隔离开关大量采用单臂垂直伸缩钳夹式结构,由于设计及工艺原因,近年来该型号隔离开关在运行中上导电管出现的问题尤为突出,以GW22A-252型隔离开关在运行中出现的主要问题为例进行分析,并提出具体改造方案,对实施后的方案进行了总结。
In the domestic substation,outdoor bus isolation switch uses a lot of single arm vertical telescopic clamp type structure,due to the design and technical reasons,the problem of this isolation switch in operation on the guide tube is particularly prominent in recent years. This paper lists some of the main problems in the operation of the GW22A-252 type isolation switch,the specific improvement of the reform program is put forward,implementation scheme is analyzed and summarized.
