摘　　要：为了实现对架空输电线路地线的远程融冰,需对地线融冰自动接线装置进行改造。本文首先介绍了装置改造的整体方案和远程控制系统的操作流程,明确合闸操作在整个融冰操作中的重要性;其次通过对比现有的就地合闸操作方式,分析直接进行远程合闸操作可能出现的故障及引起故障的原因;最后提出保留现有控制方式对电机的停转控制和合闸信号的触发,增加合闸时间-电源通断管理和电机运行电流监测等措施来避免事故的发生,铁塔上增设图像采集设备辅助识别合闸状态信息,提高远方判断合闸到位的成功率。In order to realize the long-distance ice-melting of overhead transmission lines,it is necessary to reform the automatic ice-melting wiring device.First of this paper,the whole scheme of the device modification and the operation flow of the remote control system are introduced,and the importance of the closing operation in the whole ice melting operation is clarified.Secondly,by comparing the existing on-the-spot closing operation mode,the paper analyzes the possible faults and causes of the remote closing operation.Finally,some measures are put forward to avoid the accident,such as keeping the existing control mode to control the motor's stop-turn and trigger the closing signal,increasing the closing time-power on-off management and monitoring the motor's running current,an image acquisition device is added to the tower to help identify the closing status information,so as to improve the success rate of judging the closing position from afar.
