Abstract 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.
