Dry-type transformer frequency modulation heat dissipation system

Abstract

The embodiment of the invention discloses a dry-type transformer frequency modulation heat dissipation system, which comprises a base and two supports symmetrically arranged on the two sides of the top of the base, wherein a transformer and a heat dissipation device are sequentially installed between the two supports from top to bottom, and a dustproof assembly is installed on the heat dissipationdevice; the dustproof assembly comprises a driving shaft installed on one side of the heat dissipation device through a bearing and an annular groove formed in the surface of the heat dissipation device, one end of the driving shaft is connected with a driving motor mounted on the supports, and a first connecting plate is fixedly connected to the driving shaft. According to the invention, the first dustproof net is used for isolating dust out of a heat dissipation box, and the driving motor is used for driving the first dustproof net to rotate into a water storage tank for cleaning, dust is cleaned up through forward rotation and reverse rotation of the driving motor, manual cleaning is avoided, the labor intensity of workers is reduced, and the situation that the cooling effect is reduced due to the fact that dust blocks a heat dissipation dustproof opening of the heat dissipation device can be effectively avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of transformers, and in particular to a frequency modulation cooling system for dry-type transformers. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization ( Magnetic saturation transformer), etc., dry-type transformer refers to the transformer whose iron core and winding are not immersed in insulating oil, and is widely used in local lighting, high-rise buildings, airports and docks and other places. [0003] Working in a high temperature environment for a long time will affect the normal operation and service life of the transformer. The cooling methods of dry-type transformers are divided into natural air cool...
