A high-voltage and low-voltage transformer with high safety protection

Abstract

The invention discloses a high-safety and protective high-voltage and low-voltage transformer, which belongs to the technical field of transformers, and includes a transformer casing. The inner cavity of the transformer casing is provided with a modular adjustable iron core mechanism. The insertion mechanism for cooling oil noise reduction, and the insertion mechanism is fixed in the inner cavity of the transformer housing, and the top of the iron core mechanism is provided with a corresponding insulator, the outer wall of the iron core mechanism can be adjusted to install windings, and the top of the winding corresponds to the insulator The position is fixed with a self-cleaning wiring protection mechanism. In the present invention, it is beneficial to realize the heat dissipation control of the winding, and the main body of the iron core can enter the heat dissipation oil of the transformer through the openings on both sides, and the heat dissipation treatment of the winding and the main body of the iron core can be ensured under the cooperation of a plurality of interposed spacers. Therefore, the heat dissipation adjustment ability of the iron core mechanism and the winding can be effectively improved, and the follow-up maintenance universality can be realized through the adjustable insertion spacer, and the disassembly and maintenance efficiency can be improved.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the terminals and insulators at the wiring will still be affected by the existence of oil pollution after long-term use, and the lack of corresponding heat dissipation means between the internal windings of the transformer, when the oil circuit of the oil-immersed transformer is in operation It will produce a lot of noise, which will affect the night life of nearby residents, and a high-safety and protective high-voltage and low-voltage transformer is proposed.
