摘要
The present invention relates to an oil-immersed transformer having a double cooling structure. The oil-immersed transformer having a double cooling structure comprises: an external case which forms an external appearance; a winding part which is installed inside of the external case and includes a cylindrical core and a winding surrounding a peripheral surface of a coil an oil inlet part which introduces cooling oil into the winding part; an oil discharge part from which the oil is discharged after cooling the winding part; a radiator which communicates with the oil inlet part and the oil discharge part and is installed in the outside of the external case to perform heat exchange with respect to the oil; and a separator which is disposed between the winding and the winding and separates the winding into a plurality of windings along the longitudinal direction of the coil. According to the present invention, it is possible to efficiently cool the inside of the transformer through the double cooling structure to increase a component life and a transformer life, thereby improving reliability of the transformer.;COPYRIGHT KIPO 2016
