Power transformer

Abstract

The invention provides a power transformer, and relates to the field of transformers. The power transformer comprises a base, a cylinder base is fixedly installed at the center of the top of the base,the top of the cylinder base is fixedly connected with the bottom of a hydraulic cylinder, a piston is arranged inside the hydraulic cylinder, and the top of the piston is fixedly connected with thebottom end of a pushing rod. According to the power transformer, through the arranged hydraulic cylinder, the arranged piston located inside the hydraulic cylinder, a fixing base fixedly connected with the top end of the pushing rod, a square cavity formed inside the fixing base at the same time, dampers evenly arranged at four corners of the bottom end of the square cavity at the same time and pressing rods fixedly connected with the bottom of an arranged support plate, the pushing rod is driven by the piston to act on the fixing base as required accordingly, the pressing rods conveniently drive the supporting plate to conduct position moving, the height of a transformer body is conveniently adjusted accordingly, and the working reliability of the transformer body is effectively improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a power transformer. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, or power grid for short. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage. The voltage change requires a transformer. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). A transformer is a device that transforms AC voltage, AC current, and impedance. When an AC current passes through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), which induces a voltag...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a power transformer, which solves the problem that most of the power transformer bases in the market mentioned above are fixed and the height cannot be adjusted. It is easy to generate accumulated water inside the power room, and the transformer is easy to contact with accumulated water, which will affect the reliability of the transformer.
