Transformer cooling device

Abstract

The invention discloses a transformer cooling device, and provides a transformer cooling device that can automatically start the cooling device according to the temperature change of the transformer shell, and quickly reduce the temperature of the transformer to the working temperature range of the transformer. It includes metal water tank, water pump, conduit, sliding rheostat, thermal expansion and contraction mechanism and metal heat conduction block. The thermal expansion and expansion mechanism and metal heat conduction block are closely connected to the outer surface of the transformer shell; the piston chamber of the thermal expansion and expansion mechanism is equipped with thermal expansion and contraction. Liquid, the piston in the piston chamber is connected to the sliding piece of the sliding rheostat through a telescopic rod; the metal water tank is buried under the ground below the transformer, and the metal heat conduction block, the metal water tank and the water pump are connected in sequence through a conduit to obtain a closed cavity and fill it with water ; There are also rotational speed sensors, address distributors, wireless directional transceivers, displays and satellite locators respectively connected to the controller. The invention is mainly used in the transformer cooling technology.

Description

technical field [0001] The invention relates to the technical field of transformer cooling, in particular to a transformer cooling device. Background technique [0002] The transformer will generate a lot of heat when it is working, and the heat must be transferred out in time, otherwise it will cause the temperature inside the transformer to rise and affect the working efficiency of the transformer. If the temperature is too high, it may even cause the transformer to burn, resulting in an electrical accident, which will bring huge losses to the user. [0003] The publication date is January 16, 2013, and the patent document with the publication number 102881408A discloses a self-cooling transformer, including a first winding, a second winding and an iron core wound around the first winding and the second winding. The transformer body, the transformer body is installed on a PCB board through a bracket, and the PCB board is provided with a semiconductor cooling chip driven b...
