Converter transformer valve side bushing temperature monitoring device and monitoring method

The invention discloses a converter transformer valve side bushing temperature monitoring device comprising a temperature sensor, a coordinated control module, a GSM module and a control platform; thetemperature sensor comprises a temperature measuring chip with a device code and a transceiver antenna, uses the temperature measuring chip to measure temperature of different portions of the bushing, and uses the transceiver antenna to communicate with the coordinated control module; the coordinated control module uses the transceiver antenna to read the device code of the temperature sensor andthe measured temperature value, and uses the GSM module to communicate with the control platform; the control platform sends a control order to the coordinated control module, receives data read by the coordinated control module, and determines whether the valve side bushing has an overheating fault or not. The monitoring device can monitor the temperature of different portions of the valve sidebushing, can fast locate th
