Description

double-E-shaped silicon steel sheet for transformer

Technical Field

The invention relates to the field of transformer manufacturing, in particular to a double-E-shaped silicon steel sheet for a transformer.

Background

The transformer consists of an iron core and a coil, wherein the coil is provided with two or more than two windings, the winding connected with a power supply is called a primary coil, and the other windings are called secondary coils. The core acts to enhance the magnetic coupling between the two coils. In order to reduce eddy current and hysteresis loss in the iron, the iron core is formed by laminating a plurality of silicon steel sheets.

In the prior art, the heat dissipation performance of the silicon steel sheets is poor after the silicon steel sheets are laminated into the iron core, so that the temperature of the transformer is high after long-time high-power work.

Disclosure of Invention

The invention provides a double E-shaped silicon steel sheet for a transformer, which aims to solve the technical problem that after silicon steel sheets are laminated into an iron core, the heat dissipation performance is poor, so that the temperature of the transformer is higher after the transformer works at high power for a long time.

The technical scheme adopted by the invention for solving the technical problems is as follows: the double E-shaped silicon steel sheet for the transformer comprises a body, wherein the body is provided with two E-shaped winding grooves, the two E-shaped winding grooves are bilaterally symmetrical and are connected, and heat dissipation fins are arranged at the edges of the E-shaped winding grooves.

Further: the E-shaped winding groove is provided with heat dissipation holes.

Further: the number of the heat dissipation holes is multiple, and the heat dissipation holes are uniformly distributed on the E-shaped winding grooves.

Further: the body is provided with an installation positioning hole.

Further: the shape of the heat dissipation fin is E-shaped.

The double E-shaped silicon steel sheet for the transformer has the beneficial effects that the heat of the transformer can be effectively dissipated by arranging the heat dissipation holes and the heat dissipation fins, the overhigh temperature of the transformer is avoided, meanwhile, the laminating position precision can be ensured in the installation process of the silicon steel sheet by arranging the installation positioning holes, and the influence on the quality of an iron core caused by the deviation of the silicon steel sheet is avoided.
