新型绝缘子锁紧销拔销器的研制

输电线路在长时间运行后绝缘子会出现自爆、零值、闪络等损伤情况，需要对绝缘子进行更换，绝缘子型号众多、结构不同，更换过程中部分绝缘子锁紧销不易拔出。为此，对输电线路更换绝缘子工作中存在的问题进行分析，研制出一种轻便、通用、操作简便、安全可靠的新型绝缘子锁紧销拔销器，取得了良好的应用效果。

Development of New Pin Puller of the Insulator Connection Pin

After long operation of transmission lines, there may be explosion, zero value and flashover on in-sulator. Therefore, the insulators need to be replaced. The insulators are different in types and structures, so the connection pin can not be easily pulled. Hence , the paper analyzes problems in replacing insulators on transmission lines. A kind of portable, common, convenient in operation, safe and reliable pin puller of insu-lation connection pin is developed, the use of which has achieved favorable result.
