Recently, the United States used infrared technology to monitor the temperature rise of transformers and made good progress.
The transformer of the Bmcher power station in the United States has installed more than 300 on-load tap-changer monitors to monitor the temperature rise of the tap-changer. With the monitor, the cooling characteristics of the transformer without circulating pumps can be analyzed. The infrared camera records the temperature profile of the heat sink assembly. For transformers in substations, the main components of the cooling system are cores and windings. Heat losses caused by iron cores and windings can affect transformer efficiency and life. Temperature rise can increase conductor resistance and can cause insulation degradation, resulting in transformer failure. Infrared cameras can act as a transformer for imaging, and can also show changes in temperature and color. It can directly provide visual analysis of transformer hot spots.
