On Line Monitoring System of Non-contact Infrared Temperature Measurement for Distribution Switchgear

Abstract

This paper proposes online monitoring and early warning system based on MLX90640 non-contact busbar temperature measurement switchgear. It uses MLX90640 infrared sensor module to measure the temperature of the switchgear busbar and then uses the E30-433T20D wireless communication method to transmit the temperature data to the local terminal. The practice test shows that the temperature measurement point terminal can accurately measure the bus temperature and feed the temperature back to the local switchgear terminal, which can achieve high-precision temperature measurement and early warning of the temperature of the switchgear busbar and can abnormally the temperature of the busbar in the cabinet. The position is accurately positioned to facilitate fault condition maintenance, improve the reliability of the switchgear operation, and ensure the safety of the switchgear system
