Abstract: During the operation of the high-voltage switchgears, The contact in the cabinet and the bus connection, the dynamic and static contact circuit generates too heat, which is easy to cause power failure and fire accident. Therefore, the temperature monitoring is very important in the high-voltage switch cabinet, especially the three-phase contact temperature monitoring. The traditional wired temperature measurement method can not be used because of the exposed voltage of high voltage equipment. The wireless temperature measurement system uses radio waves, no wiring, equal potential with high-voltage equipment, and no insulation measures. Therefore, the wireless temperature measurement system can solve the temperature measurement problem of high-voltage equipment.

01 Project overview

This project is the expansion project of the T1 terminal of Nanjing Lukou International Airport. It needs to be equipped with wireless temperature measurement products to realize the temperature rise monitoring of the circuit breakers in the cabinet.The working environment temperature of the sensor meets the requirement of -40℃ to +120℃. Choose ATE300 type CT inductive powered temperature sensor. And choose the ATC400 transceiver to connect to the background system.



02 Wireless temperature monitoring system introduction

The project has 11kV of switchgear need to detect cable temperature, customers consult Acrel wireless temperature measurement products, attending through Acrel ATE wireless temperature sensor and ATC receiver, the cable in the switchgear temperature detection, And through RS485 communication data transmission to the back platform for real-time monitoring, can effectively prevent overheating failure, affect the normal operation of equipment, avoid safety risks.
