Transformer shell structure with noise reduction function

Abstract

The invention belongs to the sealing pad technology field and relates to a transformer shell structure with a noise reduction function. The transformer shell structure comprises a transformer main body and a noise reduction frame. A first sliding groove is arranged in a lower surface of the transformer main body. A first spring, a telescopic rod, a corrugated plate, a limiting block, a first sliding block and a second sliding block are arranged in the noise reduction frame. A connecting plate, a second spring, a connecting rod, a convex block, a limiting circular ring and a sponge sleeve are arranged in a through hole. The limiting circular ring is located on an outer surface of the noise reduction frame. A groove is arranged in the lower surface of the second sliding block. Sound absorption cotton is arranged on an inner wall of the noise reduction frame, and the first spring and the second spring are arranged on outer surfaces of the telescopic rod and the connecting rod. By using the transformer shell structure with the noise reduction function, noises generated by the transformer main body are well reduced, and after noise reduction equipment is damaged, the transformer shell structure is convenient to install and dismount.

Description

technical field [0001] The invention relates to the technical field of gaskets, in particular to a transformer shell structure with a noise reduction function. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are a primary coil, a secondary coil and an iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. 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: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. [0003] When the...
