Introduction to Oil - Immersed Transformers
Oil - immersed transformers are a type of power transformer widely used in the power grid. They use insulating oil as both an insulating medium and a cooling medium. The insulating oil has excellent dielectric properties, which can effectively prevent electrical breakdown between the windings and other components of the transformer. At the same time, it can transfer the heat generated during the operation of the transformer to the outside through convection and conduction, ensuring the normal operation of the transformer. Oil - immersed transformers are suitable for various power distribution systems, from small - scale industrial and commercial applications to large - scale power transmission and transformation projects. They are known for their high reliability, long service life, and good overload capacity.
