Introduction to Immersed Transformers
An immersed transformer, also known as an oil - immersed transformer, is a type of power transformer where the core and windings are immersed in insulating oil. The insulating oil serves multiple crucial functions. Firstly, it provides electrical insulation between the different parts of the transformer, preventing short - circuits and ensuring the safe and efficient operation of the device. Secondly, it acts as a coolant, dissipating the heat generated during the transformer's operation. When the transformer is in use, electrical losses in the core and windings result in heat production. The insulating oil absorbs this heat and transfers it to the transformer's cooling surfaces, such as radiators or heat exchangers, where it is released into the surrounding environment.
Immersed transformers are widely used in power distribution networks, industrial plants, and large - scale commercial buildings due to their high efficiency, reliability, and ability to handle large power loads. They come in various sizes and voltage ratings to meet different application requirements.
