Research on GIS Circuit Breaker Monitoring System Based on RFID Temperature Measurement for Alpine Regions

Aiming at the problem that the insulation performance of SF6 gas is affected in the low temperature environment of GIS circuit breakers in alpine regions. A GIS circuit breaker monitoring system based on RFID passive wireless temperature measurement is designed. The temperature field of GIS circuit breaker and temperature sensor is simulated and studied by COMSOL software, and the installation position of the sensor is determined. The RFID temperature measurement data gateway is developed to realize the data reading of 8 channels of RFID temperature measurement sensors at the same time. And upload the acquired temperature data to the remote server through WiFi or 4G to realize the real-time monitoring of the shell temperature of the GIS circuit breaker. The system has the characteristics of non-contact measurement, strong anti-interference ability and wireless data transmission. Has a good application prospect.
