Abstract: In this paper,a remote diagnosis system of high-voltage disconnector based on edge computing architecture is designed.The angle,angular acceleration and battery power data of all high-voltage disconnectors in this network are collected through the edge computing server.Under the judgment and execution of the proposed intelligent decision-making mechanism,valid data are filtered and displayed.At the same time,valid data are transmitted to the remote server by wireless transmission for data summary,analysis and judgment and the on-off angle curve and angular acceleration curve of each high-voltage disconnector in the network are drawn.And according to the threshold judgment result and curve law,the on-off status of each high-voltage disconnector can be shown and the location and warning of the high-voltage disconnector with on-off faults can be carried out,which helps to realize the remote detection and status diagnosis of the high-voltage disconnector.
