Abstract

A three dimensional wound core dry type transformer for a non-magnetic clamp piece comprises high and low voltage coils, a three dimensional wound core, and a clamp piece, the coils are wound on a column of the three dimensional wound core, the clamp piece fixes an iron core and the coils so that a transformer whole structure is formed, the clamp piece of the transformer is made of a non-magnetic material, the clamp piece is in the shape of a hexagon, adjacent sides are at an included angle of 120 degrees, and the adjacent sides are not equal to a corresponding side in length, the non-magnetic clamp piece is made of a glass fiber resin material in compression molding, and can be made of non-magnetic channel steel or non-magnetic steel plates in bend machining.

Description

A kind of three-dimensional wound core dry type transformer of non-magnetic folder

Technical field

The utility model relates to a kind of three-dimensional wound core dry type transformer, belongs to field of electrical equipment, particularly a kind of three-dimensional wound core dry type transformer of non magnetic folder.

Background technology

Folder is three-dimensional wound core dry type transformer important structure parts, is mainly used in fastening between high-voltage coil and low-voltage coil and iron core, forms the overall structure of transformer.Existing three-dimensional wound core dry type transformer clamp is channel-section steel or other shape steel are made, as Guangdong Haihong Transformer Co., Ltd.'s application number three-dimensional wound core dry type transformer clamp patent that is 200820189290.9 and 200920055845.5; The patent that JiangXi Han's Power Technology Co., Ltd.'s application number is 200620163597.2 dry-type transformer with three-dimensional rolled iron core folders; The patent No. is a ZL201120224204.5 delta transformer clip patent etc., and these steel folders can produce dispersion loss, therefore, during design of transformer, all adopt the way that increases conductor cross-section, compensate this loss, this way can increase the cost of transformer.

The utility model content

The purpose of this utility model is: propose a kind of three-dimensional wound core dry type transformer of non-magnetic folder, this transformer can not produce the folder dispersion loss.

The purpose of this utility model is achieved in that a kind of three-dimensional wound core dry type transformer, by high-voltage coil and low-voltage coil, three dimensional wound core and folder, formed, coil winding is on the column of three dimensional wound core, folder is the unshakable in one's determination and fixing transformer overall structure that forms of coil, the folder of transformer is that nonmagnetic substance is made, folder be shaped as hexagon, the angle of adjacent edge is 120 degree, adjacent edge and corresponding sides are that inequilateral is long.

In the utility model: described three-dimensional wound core dry type transformer, its non magnetic folder is the compression molding of fiberglass resin class material.

In the utility model: described three-dimensional wound core dry type transformer, its folder from top to bottom is respectively non magnetic channel-section steel or non magnetic steel plate Bending Processing forms.

In the utility model: described three-dimensional wound core dry type transformer, center pull rod is fixed on the geometric center position that the hexagon folder forms plane; Six roots of sensation peripheral bar is fixed on the center on the every limit of hexagon.

In the utility model: described three-dimensional wound core dry type transformer, fixedly the peripheral bar of upper clamping piece and lower clamping piece is three, is individually fixed in the centre position on three long limits of hexagon folder.

The non-magnetic folder of transformer does not have dispersion loss, saves the wire consumption of coil, can save 10% of transformer cost, the enforcement of this transformer, and the efficiency of not only having saved material but also improved transformer, meet the international trend of energy-saving and emission-reduction, and realistic meaning is great.

The accompanying drawing explanation

Fig. 1 is the three-dimensional wound core dry type transformer of non-magnetic folder

Fig. 2 is the schematic diagram that folder adopts 3 pull bars

Fig. 3 is the schematic diagram that folder adopts 6 pull bars

Accompanying drawing discloses basic structure of the present utility model without limitation, below in conjunction with legend, the utility model is described further.

In Fig. 1,1 is low pressure end line busbar; The 2nd, the low-voltage zero line outlet; 3 low-pressure line-outgoing busbars; The 4th, coil; The 5th, lower clamping piece; The 6th, upper clamping piece; The 7th, the high-voltage terminal binding post.

Fig. 2 and Fig. 3 are respectively the schematic diagrames that folder adopts 3 and 6 pull bars; In Fig. 2 and Fig. 3,5 is lower clamping pieces; The 6th, upper clamping piece; The 8th, center pull rod; The 9th, peripheral bar.

Embodiment

In above-mentioned figure, the iron core of transformer is placed on lower clamping piece 5, and center pull rod 8, through the geometric center of three dimensional wound core, utilizes center pull rod 8 that iron core and lower clamping piece 5 are further fixedly become to integral body; Coil winding is on the column of three dimensional wound core, and coil is held on lower clamping piece; The upper end of peripheral bar 9 is fixedly connected with upper clamping piece 6, and lower end is fixedly connected with the center of lower clamping piece corresponding sides; By the six roots of sensation or 3 peripheral bars, upper clamping piece 6 and lower clamping piece 5 are connected to form the transformer overall structure to parts such as coil and iron cores.
