Introduction to Oil Immersed Transformer
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, preventing short – circuits between different parts of the transformer. Secondly, it acts as a coolant, carrying away the heat generated during the operation of the transformer, ensuring its stable performance and long – term reliability. Oil – immersed transformers are widely used in power systems, from large – scale power generation plants to distribution networks, due to their high efficiency, good insulation properties, and relatively long service life.
