Abstract

The invention discloses a dry-type electric reactor temperature detection system. According to the system, the temperature of a dry-type electric reactor is detected through a temperature detection device embedded in the dry-type electric reactor, and the detected temperature value is sent to a monitoring terminal through a data transmission device. When the monitoring terminal determines that the temperature in the dry-type electric reactor exceeds a preset temperature value, a warning signal is output. The system can detect the temperature of the dry-type electric reactor in real time so that the dry-type electric reactor can stop operating in advance before the dry-type electric reactor catches a fire and accordingly lose is reduced to the maximum extent.
