Transformer with dustproof and heat-dissipation function

Abstract

The invention discloses a transformer with a dustproof and heat-dissipation function. The transformer is composed of a transformer, wherein a fixed base plate is arranged at the bottom of the transformer; the fixed base plate and the transformer are of an integrated structure; a filter screen is arranged on the transformer, and the filter screen is fixed on the transformer through screws; side plates are arranged at the two sides of the transformer respectively, and heat dissipation holes are formed in the side plates; dust-proof plates are arranged on the heat dissipation holes, and the dust-proof plates are embedded into the heat dissipation holes through rotating screws at the two ends; connecting plates are arranged on the dust-proof plates, and the connecting plates are welded and fixed on the dust-proof plates; and springs are arranged on the connecting plates, and spring fixing buckles are arranged at the two ends of the springs. The dust-proof plates on the side plates at the two ends of the transformer, so that under the action of external wind power, the dust-proof plates can be quickly closed, and the heat dissipation openings can be shielded, and therefore, dust is prevented from entering the interior of the transformer; and when wind power disappears, the dust-proof plates can be automatically returned through the springs, so that the heat dissipation of the transformer can be realized.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a transformer with dust-proof and heat-dissipating functions. 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. According to the purpose, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). [0003] Since the traditio...
