Abstract

The utility model provides a transformer core. The industrial demand for cores can be met, the design size is more reasonable and the materials are saved. The technical scheme is that the transformer core comprises two C-shaped cores, the external height of the cores is 100-250mm, the internal height h of the cores is 60-170mm, the thickness b of the cores is 20-40mm, the internal width c of the cores is 20-50mm and the side distance of the cores a is 18-40mm. The transformer core has the beneficial effects that the industrial requirements on the specifications of the cores are satisfied, the eddy-current loss is reduced, the temperature rise is decreased and the used silicon steel sheets can be saved because the design size is reasonable.

Description

A kind of transformer core

One, technical field

The utility model relates to a kind of transformer core.

Two, background technology

Be used as the iron core of transformer, cold-reduced silicon sheet, the size by required iron core is cut into microscler with it, then overlapping one-tenth " day " font or " mouth " font.If reduce eddy current, silicon steel sheet thickness is more thin, and the slip of splicing is more narrow, and effect is more good.This has not only reduced eddy current loss, has reduced temperature rise, can also save the materials of silicon steel sheet.But when in fact making silicon sheet core, mostly model is single, can't satisfy industry to the requirement of its size.

Three, summary of the invention

The utility model provides a kind of transformer core, makes iron core all satisfied to some extent to the demand of industry, and reasonably design size is arranged, and has saved material.

Technical solution adopted in the utility model is:

A kind of transformer core comprises 2 iron cores that are shaped as the C type, and described iron core external height is 100-250mm, and internal height h is 60-170mm, and thickness b is 20-40mm, and inner width c is 20-50mm, and back gauge a is 18-40mm.

Described iron core external height is 120mm, and internal height h is 80mm, and thickness b is 30mm, and inner width c is 35mm, and back gauge a is 25mm.

Also be sprayed with insulating varnish in described iron core outside.

The beneficial effects of the utility model are to make industry all be satisfied the specification requirement of iron core, have reduced eddy current loss, have reduced temperature rise, and because design size is reasonable, can also save the materials of silicon steel sheet.

(5) embodiment

Embodiment:

In Fig. 1,2, a kind of transformer core comprises 2 iron cores that are shaped as the C type, and described iron core external height is 120mm, and internal height h is 80mm, and thickness b is 30mm, and inner width c is 35mm, and back gauge a is 25mm.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
