CN206098099U - Metallic glass transformer iron core structure - Google Patents

Abstract

The utility model provides a metallic glass transformer iron core structure, includes frame iron core and inside casing iron core, frame iron core and inside casing iron core all are O shape, the inside casing iron core is fixed in the frame iron core is inboard, and both flush in one side of direction of height, just the inside casing iron core is less than at the opposite side of direction of height the frame iron core. The utility model discloses simple structure, it is convenient, with low costs to make, because the inside casing iron core is less than the frame iron core in one side, can make the coil of walking around this side form certain arc chord angle, has improved coil mechanical strength, and anti burst short circuit can the reinforce.

Description

Amorphous alloy transformer core structure

Technical field

This utility model belongs to transformer technology field, more particularly to a kind of amorphous alloy transformer core structure.

Background technology

Amorphous alloy transformer is the transformator using amorphous alloy material as iron core.

At present, amorphous alloy transformer is more and more, and its iron core is all high using a kind of piece on a transformator, causes Transformer coil must adopt rectangle, and this mechanical strength to product is very unfavorable.

Utility model content

Based on this, for above-mentioned technical problem, there is provided a kind of amorphous alloy transformer core structure.

To solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：

A kind of amorphous alloy transformer core structure, including housing iron core and inside casing iron core, the housing iron core and In O shapes, the inside casing iron core is fixed on the inside of the housing iron core inside casing iron core, and both are flushed in the side of short transverse, And the inside casing iron core is less than the housing iron core in the opposite side of short transverse.

The height of the housing iron core is 142mm, and the height of the inside casing iron core is 122mm.

This utility model simple structure, easily manufactured, low cost, as inside casing iron core is less than housing iron core in side, can Make the coil for bypassing the side form certain arc chord angle, improve coil mechanical strength, anti-sudden short circuit ability is strong.

Description of the drawings

This utility model is described in detail with reference to the accompanying drawings and detailed description：

Fig. 1 is structural representation of the present utility model；

Fig. 2 is cross section structure diagram of the present utility model；

Fig. 3 is the structural representation after this utility model core structure coiling；

Fig. 4 is the structural representation of existing amorphous alloy transformer core.

Specific embodiment

As Figure 1-3, a kind of amorphous alloy transformer core structure, including housing iron core 11 and inside casing iron core 12.

, in O shapes, inside casing iron core 12 is fixed on the inside of housing iron core 11, Liang Zhe for housing iron core 11 and inside casing iron core 12 The side of short transverse flushes, and inside casing iron core 12 is less than housing iron core 11 in the opposite side of short transverse, as shown in figure 3, When transformer coil 2 bypasses this utility model iron core 10, as inside casing iron core 12 is less than housing iron core 11 in side, can make to bypass this The coil 2 of side forms certain arc chord angle, and the anti-sudden short circuit ability of coil is higher.

Specifically, as shown in Fig. 2 the height H of the housing iron core 11 of the present embodiment is 142mm, the height h of inside casing iron core 12 For 122mm.

But, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally Utility model, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to The change of the upper embodiment, modification will all fall in Claims scope of the present utility model.

Claims (2)

1. a kind of amorphous alloy transformer core structure, it is characterised in that including housing iron core and inside casing iron core, the housing Iron core and inside casing iron core are in O shapes, and the inside casing iron core is fixed on the inside of the housing iron core, and both are the one of short transverse Side flushes, and the inside casing iron core is less than the housing iron core in the opposite side of short transverse.

2. a kind of amorphous alloy transformer core structure according to claim 1, it is characterised in that the housing iron core Highly it is 142mm, the height of the inside casing iron core is 122mm.
