A transformer with explosion-proof function

Abstract

A transformer with explosion-proof function, comprising a transformer housing, a pressure relief hole is penetrated through the transformer housing, a pressure relief piston is slidably connected in the pressure relief hole, the upper end of the pressure relief piston and the connecting rod The lower end is fixedly connected, the side of the upper end of the connecting rod is hingedly connected with one end of the connecting rod, the upper end of the transformer housing is fixedly provided with a cylinder, and a buffer slide bar is slid inside the cylinder, and the buffer slide bar and Buffer springs are connected between the cylinders. In the present invention, when the temperature inside the transformer casing increases and the air pressure increases, the pressure relief piston slides to the upper end of the pressure relief hole, so that the high-pressure gas inside the transformer casing flows from the side of the pressure relief piston. The opening is discharged to relieve pressure. When the pressure relief piston slides upward, it drives the connecting rod to push the buffer slide bar. When the buffer slide bar slides, it squeezes the buffer spring, which can effectively reduce the impact force during pressure release.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer with an explosion-proof function. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. [0003] The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.).

AI Technical Summary

Problems solved by technology

[0004] Most of the transformers in the prior art are sealed structures with poor heat dissipation. When a fault occurs, the temperature inside the transformer rises sharply and cannot be discharged quickly, resulting in an increase in the pressure inside the transformer, which is prone to explosion accidents. Therefore, we A transformer with explosion-proof function is proposed to solve the above problems
