Power transformer

Abstract

The invention relates to the field of transformers, in particular to a power transformer which comprises a transformer body, supporting columns are arranged at the four corners of the transformer body, cavities are formed in the supporting columns, sliding grooves are formed in the front surfaces of the supporting columns and communicate with the first cavities, and supporting devices are arranged in the cavities. Supporting rods are fixedly connected to the upper surfaces of the supporting columns, protective devices are arranged at the upper ends of the supporting rods, rolling wheels are arranged at the bottoms of the supporting columns, threaded grooves are formed in the bottoms of the supporting columns, and supporting circular truncated cones are arranged in the threaded grooves. According to the power transformer, when the transformer is transferred, the situation of collision does not exist, the situation that the transformer body is exposed in the air and is drenched by the rain can be avoided in rainy days, and the transformer body is protected.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a power transformer. Background technique [0002] Power transformer is a kind of static electrical equipment, which is used to change the AC voltage (current) of a certain value into another voltage (current) with the same frequency or several voltages (current) with different values. It is realized according to the principle of electromagnetic induction. Power transmission is a necessary equipment for power transmission and distribution, and power distribution for power users; [0003] An invention patent with the patent number CN211376352U discloses a power transformer, which includes a transformer main body and a fixing base. The bottoms on both sides of the transformer main body are fixedly connected with connecting bases, and the top of the connecting base is provided with two mutually parallel And the symmetrical connection slot, the position of the top of the connection seat ...

AI Technical Summary

Problems solved by technology

[0004] However, in daily life, power transformers are large in size and heavy in weight, which is inconvenient for short-distance movement and prone to bumps. When transferring power transformers over long distances, collisions between power transformers and forklifts or transfer tools often occur. The outer surface of the power transformer is damaged, and the surface of the power transformer cannot be covered. The power transformer is exposed to rain, which causes damage to its surface and internal components
