Assembling structure for power transformer iron core

Abstract

The invention relates to an assembling structure for a power transformer iron core. The assembling structure comprises an iron core and a high and lower pressure clamping members arranged on two sides of the iron core, wherein a grounding sheet is arranged on one side, where the upper end of the iron core is close to the low pressure clamping member; the lower end of the iron core is provided with a food pad; a foot pad insulating block is arranged between the foot pad and the iron core; one side of the high pressure clamping member is provided with a cover plate assembly; the high pressure clamping member is connected and fixed with the upper end of the low pressure clamping member via an insulated retractable belt; the iron core is rectangular; two sides of the iron core are provided with side columns; a middle column is disposed in the middle of the iron core; the cover plate assembly is formed by a cover plate, a lock sheet and a shaft all connected with each other; a foot pad cushion block is further placed between the iron core and the foot pad; the upper end of the iron core and one side of the low pressure clamping member are provided with a wood cushion block; side beams are arranged on the external sides of the side columns on two sides of the iron core; the upper end of the iron core is provided with an upper beam; and two sides of the upper end of the iron core are respectively provided with a paper plate. Compared with the prior art, the assembling structure for the power transformer iron core has compact structure and rational design, requires low manufacturing cost, and has great product heat radiation speed, low temperature increase, great reliability and low energy loss.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an assembly structure of a power transformer iron core. Background technique [0002] A transformer is a power device that uses the principle of electromagnetic induction to change the AC voltage. It can play the role of voltage conversion, current conversion, impedance conversion, and voltage stabilization in the circuit. It is widely used in many fields such as power supply, machinery manufacturing, metallurgy, and railways. . The iron core is an important part of the transformer. It is mainly composed of the iron core and the coil. During the working process, the iron core will generate loss to convert part of the electric energy into heat energy, resulting in waste of power supply. The loss of energy will also increase the temperature of the iron core. If the iron core works at high temperature for a long time, the insulating layer on its surface will age, which will fu...

The iron core is an important part of the transformer. It is mainly composed of the iron core and the coil. During the working process, the iron core will generate loss to convert part of the electric energy into heat energy, resulting in waste of power supply. The loss of energy will also increase the temperature of the iron core. If the iron core works at high temperature for a long time, the insulating layer on its surface will age, which will further increase the loss
