摘要
特高压线路定期检修过程中需要挂接大量的接地线,现有的全铜鳄鱼嘴式接地线夹夹头处容易松开,导致线夹与导线接触不良,严重时会磨损、烧蚀导线。研制了一种电动接地夹头装置,无需操作人员下跳线即可通过无线控制快速实现挂、拆接地线,特殊情况下可通过手动操作打开接地装置。该接地装置在保证导线接地效果的同时,也保障了工作人员作业安全。
During the regular maintenance of UHV lines,a large number of grounding wires need to be hung.The existing all copper crocodile mouth grounding wire clamp is easy to loosen,resulting in poor contact between the clamp and the conductor,which will wear and ablate the conductor in serious cases.In this paper,an electric grounding chuck device is developed,which can quickly realize the grounding and removal of the ground wire through wireless control without the operator removing the jumper.If it is impossible to remove the grounding wire remotely and electrically under special circumstances,the grounding device can also be opened by manual operation.The grounding device not only ensures the grounding effect of the conductor,but also ensures the operation safety of the staff.
