Abstract

The present invention relates to a cooling device, and in particular to a cooling device for an oil-immersed power transformer. The present invention provides a cooling device for an oil-immersed power transformer that is easy to disassemble to reduce the difficulty of maintenance. A cooling device for an oil-immersed power transformer includes a base frame, a box, a top plate, a movable plate, a support frame, a fan, etc. A box is provided on the top of the base frame, a top plate is provided on the top of the box, and four threading grooves are evenly opened on the left and right sides of the top plate for connecting cables to the transformer. A movable plate is rotatably provided on the right side of the box, and the movable plate is in contact with the top plate. A support frame is provided in the middle of the movable plate, and a fan is symmetrically provided in the support frame, and the fan can cool the transformer. By manually pulling the handle to drive the movable plate to open, the transformer can be installed inside the box, which is convenient for people to remove and repair to ensure the service life of the transformer.
