摘　　要：针对隔离开关引线及其弛度暂无固定检修标准导致开关引线安装方式多样、弛度长短不一、容易发生动态绝缘距离不足、引线从线夹抽脱等问题,从线索与温度变化的关系方面进行思考和推理,提出了通过测量安装长度来衡量引线弛度是否符合要求的方法,以及引线检修的注意事项,对隔离开关引线施工及检修具有一定参考意义。With regard to the problems of lack of unified criteria for maintenance of leads of disconnector and their sags,resulting in different installation methods,various lengths of sags,liability to suffer from insufficient dynamic insulation distance or falling off of lead from the clamp,the paper takes account of and infers the relationship between the leads and temperature changes,puts forward a methods whether the sag of lead weighted by means of measurement of installation length are meeting the requirements,proposes the precautions for inspection and repair of the leads,having certain value of reference for construction,inspection and repair of leads of disconnector.
