High-low voltage transformer with high safety protection

Abstract

The invention discloses a high-low voltage transformer with high safety protection, and belongs to the technical field of transformers. The transformer comprises a transformer shell, an inner cavity of the transformer shell is provided with a module adjustable iron core mechanism, the bottom of the iron core mechanism is fixedly provided with an insertion mechanism for cooling oil liquid noise reduction, and the insertion mechanism is fixedly arranged in the inner cavity of the transformer shell; and a corresponding insulator is arranged at the top of the iron core mechanism, a winding is adjustably installed on the outer side wall of the iron core mechanism, and a self-cleaning wiring protection mechanism is fixedly arranged at the position, corresponding to the insulator, of the top of the winding. According to the invention, heat dissipation control over the winding is facilitated, the iron core body can enter transformer heat dissipation oil through the openings in the two sides, heat dissipation treatment on the winding and the iron core body is guaranteed under cooperation of the multiple inserted spacers, and therefore the heat dissipation adjusting capacity of the iron core mechanism and the winding can be effectively improved; and in addition, the subsequent maintenance universality is realized through the adjustable inserted spacer, and the disassembly and assembly maintenance efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a high-voltage and low-voltage transformer with high safety protection.

The invention is provided with ...

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.
