Research and Application of Intelligent Monitoring Device for Opening and Closing Position of Isolation Switch of Overhead Distribution Line

With the continuous advancement of distribution network automation, the number of isolation switch and the number of operation increased year by year, and the people and property needed to send people to the site to check the switching position also increased greatly. In order to save the investment in human resources and property and allocate resources reasonably, this paper develops an intelligent monitoring device for the opening and closing position of the isolation switch of overhead distribution line to realize real-time monitoring of the isolation switch position.
