Research on Condition Monitoring of Substation Heater Based on Internet of Things

Heater in box substation plays an increased body temperature, moisture, and expulsion of condensation and deicing effect, the operation of the power supply system are an important part of, because of the cabinet put oneself in another's scattered layout, monitor, hard times, the data cannot be exchanged, causes the heater control still is in a state of manual cutting, artificial maintenance, for the running state of the heater can't real-time monitoring and control, In this paper, the heater condition monitoring module is developed by means of series resistance in the heater loop, which can monitor the running state of the heater in real time and upload the running data to the monitoring background, through which the switching action of the heater can be controlled remotely. It can effectively solve the problem of heater fault troubleshooting difficulty and unable to monitor, improve the efficiency and safety of maintenance personnel maintenance, and provide a new idea and scheme for the research and design of substation heater, which has important guiding significance.
