Abstract: In order to achieve remote control of the earth wire de-icing automatic connection device installed on the high-voltage transmission tower, suitable online energy extraction methods need to be provided. This paper compares the advantages and disadvantages of natural energy power generation and transmission line extraction of electric energy, and proposes that photovoltaic energy storage should be used to provide on-site energy for the system; the power consumption of remote control system in different operating stages is analyzed, and the battery capacity and photovoltaic square array of different materials are calculated; draw a conclusion to choose the NCM battery as energy storage battery, and point out that an intelligent power management system should be set up to ensure that the remote control system can operate without failure for a long time.
Key words: remote control; high voltage power extraction; NCM battery; intelligent power management system
