Research on Fixed Separated Low Voltage Switchgear Based on Electronic Sensing Technology

Abstract

In order to solve the problem of poor accuracy of traditional partial discharge identification methods for switchgear, this study introduces the control principle of single chip microcomputer and designs a new partial discharge identification method for switchgear. Firstly, the partial discharge characteristic data of the switch cabinet are collected to detect the operation state of the switch cabinet and the abnormal values therein. Then, according to the acquisition results, the characteristic types of partial discharge in the switch cabinet are judged, thus realizing the identification of partial discharge in the switch cabinet. The simulation results show that the recognition method has high recognition accuracy and the recognition process takes less time, which proves that the method is practical and reliable.
