A transformer skeleton with shielding function

Abstract

The invention discloses a transformer skeleton with a shielding function. The transformer skeleton comprises a skeleton body, wherein the skeleton body comprises an upper transverse plate, a lower transverse plate and a middle winding frame; the upper transverse plate comprises a high-tension coil transverse plate and a low-tension coil transverse plate; the high-tension coil transverse plate is arranged on the left side of the upper part of the middle winding frame, and the low-tension coil transverse plate is arranged on the right side of the upper part of the middle winding frame; a shielding hole is formed in the middle winding frame; a shielding plate is arranged in the shielding hole; and the shielding plate comprises a transverse beam, a shielding clamping strip, a first shielding baffle plate and a second shielding baffle plate. The transformer skeleton is reasonable in structural design and low in production cost, coils are isolated from one another, the potential safety hazards such as coil short connection are eliminated, the shielding effect is good, the electromagnetic interference problem of a transformer is effectively improved, the shielding plate is simple and convenient to disassemble, manpower and material resources are saved, and the service life of the transformer is prolonged.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a transformer skeleton with a shielding function. 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.). Circuit symbols often use T as the beginni...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the structure of the transformer skeleton is complicated, the manufacturing cost is high, and the individual coils are not well isolated. When the transformer needs to move or work for a long time, the coils of each strand often contact each other, which is prone to Short circuit, there are serious safety hazards, and it is prone to fire and other dangers. When the transformer is working, the electromagnetic interference between the coils is serious, which is not conducive to the normal and safe operation of the transformer. The service life of the transformer is short, resulting in a waste of resources.
