变电运检自动挂接接地线机器人的研发

Research and Development of Automatically Connecting Grounding Wire Robot for Substation Operations Inspection

本文介绍了接地线是电力系统中为了在已停电的设备和线路上意外地出现电压时,保证工作人员安全的重要工具,其作用是在高压设备进行停电检修或进行其他工作时,防止设备突然来电和邻近高压带电设备产生感应电压对人体的危害,同时泄放断电设备的剩余电荷。针对以上情况,研发了一种适用于220 kV及以上电压等级的变电设备接地装置,能够通过自动设备挂接地线的方式,对设计高度较高的超高压、特高压户外敞开式电气设备进行安全接地。

This paper introduces that grounding wire is an important tool to ensure the safety of workers when voltage unexpectedly appears on the outage equipment and line in power system.Its function is to prevent the sudden incoming of equipment and the induction voltage generated by adjacent high-voltage live equipment from coming to people when the high-voltage equipment undergoes outage overhaul or other work.At the same time,the residual charge of the power-off equipment is released.In view of the above situation,a grounding device for 220 kV and above voltage level substation equipment is developed.The device can safely grounding the high-designed UHV and UHV outdoor open electrical equipment by hanging the grounding wire with automatic equipment.
