Transformer heat dissipation device

Abstract

The invention relates to a transformer heat dissipation device which comprises a fin shell and an oleophobic coating. A sealing ring is arranged above the exterior of the fin shell, a solar panel lifting assembly is fixed to one side of the exterior of the fin shell, and the oleophobic coating is located on the inner wall of the fin shell. The device has the beneficial effects that according to the transformer cooling device, oil liquid can pass through the filtering assembly when pumped back, a cylindrical filtering net in the filtering assembly can filter the oil liquid and remove impurities, so that the purity of the oil liquid is improved, when a pin rod is bounced into a fin type auxiliary tank body hole, a fin type auxiliary tank body and a fin type main tank body are connected and installed, the fin-type auxiliary tank body can be disassembled by pulling up a pin rod, later maintenance and repair are facilitated, an electromagnetic valve is closed, the two ends of the filter assembly are closed, the fin-type auxiliary tank body can be disassembled to replace a cylindrical filter screen under the condition that the transformer heat dissipation device is not shut down, a second flow meter can monitor the flow of the filter assembly, and when the flow of the filter assembly is abnormal, the blockage of the cylindrical filter screen can be known.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer cooling device. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions of the transformer are: voltage conversion, current conversion, impedance conversion, isolation, Voltage stabilization (magnetic saturation transformer), etc., can be divided into power transformers and special transformers according to their uses. The transformer needs to be used with a transformer cooling device to dissipate heat. [0003] The existing transformer cooling device has a single function, simple structure, no filtering function, and cannot be repaired and maintained during the operation of the transformer cooling device. The cooling oil will contain a large amount of impurities after l...
