Abstract
The utility model relates to a transformer, in particular to a special transformer for skin-effect heating cables. The transformer comprises an iron core, two sides of the iron core are respectively provided with a post, an A-phase coil is wound on one of the posts, a B-phase coil and a C-phase coil are wounded on the post on the other side of the iron core, winding directions of the coils are the same, and tails of the A-phase coil and the B-phase coil are in short connection with the head of the C-phase coil. Compared with the prior art, the transformer has the advantages of reasonable design, simple structure, low manufacturing cost, wide applicable range and high balance.
Description
Technical field
The utility model relates to a kind of transformer, specifically provides a kind of kelvin effect accompanying-heat cable dedicated transformer.
Background technology
Transformer under the prior art, the especially employed transformer of kelvin effect accompanying-heat cable, its iron core winding mode can only make two single-phase transformers and satisfy use, and coiling can cause elementary three-phase imbalance under the situation that two loads are arranged.
Summary of the invention
The utility model is at above problem, and a kind of kelvin effect accompanying-heat cable dedicated transformer is provided, and it passes through the reasonable coiling to A phase coil, B phase coil and C phase coil, thereby makes three-phase electricity be converted into the two-phase electricity of balance, is applicable to two phase loads.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of kelvin effect accompanying-heat cable dedicated transformer, comprise iron core, described iron core both sides are provided with a column cap separately, the A phase coil is wound on the column cap, B phase, C phase coil are wound on the column cap of an other side, its coiling direction is identical, and the afterbody of A phase coil, B phase coil is with the head short circuit of C phase coil.
Kelvin effect accompanying-heat cable dedicated transformer of the present utility model, it passes through the reasonable coiling to A phase coil, B phase coil and C phase coil, thereby makes three-phase electricity be converted into the two-phase electricity of balance, is applicable to two phase loads.The primary balance is applicable under the situation of two-phase balanced load more than 98%.Elementary three phase winding internal resistance differences, and the number of turns is also different.Transformer can be divided into two kinds of dry type and oil immersions.
Compared with prior art, kelvin effect accompanying-heat cable dedicated transformer of the present utility model has more characteristics reasonable in design, simple in structure, that cost of manufacture is low, the scope of application is wide, balance is strong.
Description of drawings
Fig. 1 is the structural representation of kelvin effect accompanying-heat cable dedicated transformer.
Embodiment
Below in conjunction with the drawings and specific embodiments kelvin effect accompanying-heat cable dedicated transformer of the present utility model is further described.
As shown in drawings, a kind of kelvin effect accompanying-heat cable dedicated transformer, comprise iron core 1, described iron core 1 both sides are provided with a column cap 2 separately, A phase coil 3 is wound on the column cap 2, B mutually 4, C phase coil 5 is wound on the column cap 2 of an other side, and its coiling direction is identical, and the afterbody of A phase coil 3, B phase coil 4 is with the head short circuit of C phase coil 5.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
