Abstract

The utility model provides a three-phase combination transformer, belongs to the technical field of three-phase combination transformers and solves the problems that the whole weight of the conventional three-phase combination transformer is heavy, and the conventional three-phase combination transformer is difficult to operate on the site. The three-phase combination transformer comprises connection arms for fixedly connected different single-phase transformers. By the connection arms, the three single-phase transformers are connected into a whole, the single-phase transformers can be simultaneously taken in place accurately, and the whole weight of the three-phase combination transformer and the on-site operation difficulty are reduced.

Description

Three-phase combined transformer

Technical field

The utility model belongs to the transformer technology field, is specifically related to a kind of three-phase combined transformer.

Background technology

In existing three-phase combined transformer, for guaranteeing the mutual alignment between each single-phase transformer, the general locate mode that adopts three-phase combined transformer as illustrated in fig. 1 and 2, as seen from Figure 1, for the relative position that guarantees that three-phase combined transformer three is alternate, place a base 1 in the bottom of this three-phase combined transformer and be used for fixing three single-phase transformers 4, this base 1 is positioned on the on-the-spot basis 2, and three single-phase transformers 4 are fixed in respectively the relevant position of base 1 with bolt.But so just need to increase the overall weight of product to base 1 of each single-phase transformer 4 configurations, need simultaneously to make base 1 and single-phase transformer 4 usefulness bolts to fix, increase the difficulty of execute-in-place.

Summary of the invention

The purpose of this utility model is that the syndeton that solves existing three-phase combined transformer exists the problem that overall weight is large, the execute-in-place difficulty is large that causes product, and a kind of three-phase combined transformer is provided.

The technical scheme that solution the utility model technical problem adopts is a kind of three-phase combined transformer, comprises three single-phase transformers, also comprises: for the linking arm that different described single-phase transformers is fixedly connected with.

Preferably, at least one end of described linking arm is link, described link have for the link of another linking arm or the syndeton that removably connects with described single-phase transformer.

Preferably, an end of described linking arm is link, and the other end is the stiff end that is fixed on the described single-phase transformer.

Preferably, described stiff end is fixed by welding on the described single-phase transformer.

Preferably, the stiff end of described linking arm is fixed on the side of described single-phase transformer, and described linking arm is perpendicular to the side of described single-phase transformer.

Preferably, the described syndeton that removably connects is that bolt connects, sells any one in connection, the key connection.

Preferably, the described syndeton that removably connects is that bolt connects, and described link has the through hole that passes for bolt.

Preferably, connection metal bellows between described single-phase transformer is provided with in the described metal bellows for the interconnective electrical wiring of described single-phase transformer.

Preferably, described three single-phase transformers are arranged along a straight line, and described linking arm is fixedly connected with the adjacent side of adjacent single-phase transformer.

In the three-phase combined transformer of the present utility model, to utilize linking arm that three single-phase transformers are joined together to form an integral body, simultaneously can guarantee three accuracys that single-phase transformer is in place, save base, reduced the overall weight of product, reduce the execute-in-place difficulty.

Embodiment

For making those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment 1

Present embodiment provides a kind of three-phase combined transformer, and it comprises: three single-phase transformers;

For the linking arm that different single-phase transformers is fixedly connected with.

Embodiment 2

Present embodiment provides a kind of three-phase combined transformer, shown in Fig. 3 and 4, it comprises three single-phase transformers, when assembling at the scene, three single-phase transformers independently are seated in the transformer user to shift to an earlier date on the ready-made on-the-spot basis 2, connects fixing as a whole by the linking arm 3 between three single-phase transformers.

Preferably, three single-phase transformers 4 are pressed " one " word arrangement setting; Certainly, also can adjust according to actual needs the ordered state of three single-phase transformers 4 during practical application.

Preferably, above-mentioned linking arm 3 is arranged between the adjacent single-phase transformer 4, certainly, also can according to circumstances between non-conterminous single-phase transformer 4 linking arm 3 be set; Preferably, above-mentioned linking arm 3 is arranged on the middle and upper part of adjacent single-phase transformer 4 sides, and certainly, linking arm 3 also can be arranged on the bottom of above-mentioned single-phase transformer 4 sides; Preferably, above-mentioned linking arm 3 is 2, and certainly, the number of linking arm 3 also can be 3-4.

Preferably, wherein each linking arm 3 all has stiff end and movable end, and stiff end wherein is welded on the single-phase transformer 4, certainly, also can be riveted on the single-phase transformer 4; Preferably, above-mentioned stiff end is fixed on the side of single-phase transformer 4, and these linking arm 3 integral body are perpendicular to the side of above-mentioned single-phase transformer 4.
