The utility model relates to a temperature monitoring system for electric power equipment in a substation. The wireless communication terminal of the system includes IPC, and IPC connected and a wireless temperature measuring unit; the wireless communication terminal for wireless communication with the wireless temperature measuring unit; the wireless temperature measuring unit comprises a wireless transceiver module CPU and CPU respectively with the temperature signal input and calibration signal input end connected temperature sensing unit and a temperature adjusting unit with CPU, the communication terminal two-way electric connection. Due to the sensor in the high voltage environment easily lead to premature aging, temperature measurement accuracy of large deviation, so the system adopts dual sensor can almost synchronous aging online calibration, sensor solves the problem of big deviation of temperature after aging.
