Abstract：High-voltage switchgear is one of the important equipment to ensure the safe operation of the power system in substations.Therefore, the stable operation of the switchgear is of great significance to the entire power system. The aging of equipment and long-term high-load operation may cause the local temperature of the equipment to be too high and cause fire.Therefore, temperature detection of sensitive equipment in substations becomes particularly important.
