摘　　要：紧凑型输电线路具有扩大输送容量、减少线路走廊、经济效益和社会效益显著等优点,近年来得到了大力推广和应用。然而,日渐增多的紧凑型输电线路结构复杂、空气绝缘间隙小,开展带电作业的技术难度较高,传统带电作业方法也存在诸多不足。为此,文章结合实际,研制了一种绝缘机械摇臂,作为紧凑型输电线路带电作业辅助进电位工具,从绝缘机械摇臂本体、带闭锁保护装置的导线侧挂钩、绝缘机械摇臂转动装置及绝缘机械摇臂连接装置四个方面介绍了该工具的装置原理,最后加以应用研究。结果表明,该工具可在带电导线与横担头之间搭设一个绝缘平台,作业人员可通过此平台安全、便捷、高效进出电场,不仅克服了传统带电作业方式应用的难题,还显著提升了带电消缺效率和电网运行的可靠性。Compact electricity transmission lines have the advantages of expanding transmission capacity,reducing line corridors,significant economic and social benefits,and have been vigorously promoted and applied in recent years.However,the increasing number of compact electricity transmission lines have complex structures and small air insulation gaps.It is difficult to carry out live working,and the traditional live working methods also have many shortcomings.Therefore,combined with the actual situation,this paper develops an insulated mechanical rocker arm as an auxiliary potential-feeding tool for live working on compact electricity transmission lines.The device principle of the tool is introduced from four aspects:the insulated mechanical rocker arm body,the wire side hook with locking protection device,the insulated mechanical rocker arm rotation device and the insulated mechanical rocker arm connection device.Finally,the application research is conducted.The results show that the tool can set up an insulation platform between the live wire and the cross arm head,and the operator can enter and exit the electric field safely,conveniently and efficiently through this platform,which not only overcomes the problems of traditional live working method application,but also significantly improves the efficiency of live defect elimination and the reliability of power grid operation.
