Transformers are devices that use electricity to change one form of energy into another. They’re used in a lot of different devices, from electric cars to power grids. But all these transformations can be dangerous if the transformer isn’t properly protected from overheating. In this blog post, we’ll talk about how thermal protection can help keep your transformers safe.

How does a thermal protector work?


Bimetallic plates are used to create switches or relays according to the Thermal Protector Switch design idea. Bimetallic plates are created by laminating two layers of alloys with various thermal expansion coefficients. The expansion coefficient of the active layer is high, whereas that of the passive layer is low. Because the active layer and the passive layer have different expansion coefficients, the bimetal will flex and deform as the temperature rises. The bimetal will resume its original shape after the temperature is stabilized, creating a switch that responds to temperature fluctuations by closing and opening. The thermal protection must be placed as close to the heat source as possible when being installed.


Benefits of Thermal Protection for Transformers


Transformers are typically designed to operate at certain temperatures, but if the temperature rises too high, the transformer can become damaged. Thermal protection can help prevent this by monitoring the temperature and shutting down the transformer when it reaches a dangerous level.


Some benefits of using thermal protection include:


-Reduced damage from overheating.

– Increased lifespan of the transformer.

– Reduced energy costs.
