Simulation and Experimental Study on Thermoelectric Characteristics of High Voltage Disconnector

Thermoelectric generation technology can convert waste heat into electrical energy and is expected to become a new means of energy supply for power sensor nodes in future. In this paper, GW9 high voltage isolation switch and TEG1 thermoelectric generation module were taken as the objects, and the simulation model of high voltage isolation switch thermoelectric generation based on ANSYS was established. In addition, the corresponding experimental platform was built. The temperature difference between hot and cold ends and open circuit voltage characteristics of thermoelectric power generation modules were studied when the disconnector loads different working currents. When the thermoelectric module is connected to different load resistors, the variation of output power and energy conversion efficiency of the module was revealed. The simulation results are in good agreement with the experimental results, which provides an important reference for the application and development of thermoelectric generation technology in state-aware node power supply of high voltage switchgear.
