AI Technical Summary

Technical Problem

The shielding effect of the existing transformer core shielding device is not ideal enough, making it difficult to achieve all-round shielding without dead angles, which affects the energy efficiency of the transformer and may lead to problems such as overheating and increasing noise.

Method used

The full iron core shielding device is adopted, including upper iron yoke shielding, side yoke shielding and core column shielding. These shielding layers form the full iron core shielding layer of the core column-iron yoke-side yoke. The principle of electric field shielding is used to induce and neutralize the electric field inside the transformer to achieve all-round shielding.

Benefits of technology

It significantly improves the stability and reliability of the transformer, reduces electromagnetic noise and energy losses, extends the service life of the transformer, and reduces maintenance costs.

Abstract

The invention discloses a transformer full iron core shielding device and a working method thereof, and belongs to the technical field of transformers. The device comprises an upper iron yoke shield, a side yoke shield and a core column shield, the upper iron yoke shield is positioned at the lower end of the upper iron yoke of the transformer; a plurality of upper iron yoke shields are arranged and are connected end to end, a circular gap is reserved at the joint, and the diameter of the circular gap is equal to that of a transformer iron core column; the core column shielding sleeve is arranged outside a transformer core column and is connected with the upper iron yoke shielding; the return yoke shield is located on the inner side of the iron core return yoke. The conductive shielding layer is arranged on the periphery of the transformer iron core, an electric field is stopped on the surface of the conductor through the conductivity of the conductive material, and inductive charges on the surface of the conductor are neutralized through the ground wire, so that mutual interference generated by electrostatic coupling is prevented. By adopting the design of the omni-directional shielding iron core, the stability and reliability of the transformer can be remarkably improved, and electromagnetic noise and energy loss are reduced.
