Abstract

The utility model discloses a three-phase transformer structure. The three-phase transformer structure comprises a long strip-shaped iron core, extending parts are formed in the middle, the lateral walls at two sides of the front portion, and the lateral walls at two sides of the rear portion of the iron core, the extending directions of the extending parts are stagger, a coil winding is wound on each extending part, and a separation plate is arranged between every two adjacent extending parts. The three-phase transformer structure can effectively prevent the problem of mutual inference among the coils, and improves the work stability of a transformer.

Description

A kind of three-phase transformer structure
Technical field
The utility model relates to field transformer, is specially a kind of three-phase transformer structure.
Background technology
Three-phase transformer is the power equipment commonly used of power transformation transmission, plays the effect of time variant voltage.The prior art three-phase transformer consists of three iron cores and the coil windings that is wrapped on iron core, is wound with respectively two coils of high and low pressure of homophase toward each other on each iron core, and there is between coil the easily problem of phase mutual interference in the three-phase transformer of this structure.
The utility model content
The purpose of this utility model is to provide a kind of three-phase transformer structure, to solve the problem of easy phase mutual interference between prior art three-phase transformer coil.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
a kind of three-phase transformer structure, include the iron core of strip, it is characterized in that: the front portion of described iron core, both sides, rear portion sidewall forms respectively the extension that extends straight down, both sides, the middle part sidewall of iron core forms respectively the extension that extends straight up, be wound with respectively coil windings on each extension, also include a pair of dividing plate of being made by exhausted magnetic material respectively, two dividing plate centers are respectively equipped with the installation through hole, one of them dividing plate is installed through hole by center and is arranged on the iron core front portion, on iron core between the extension of middle part, another dividing plate is installed through hole by center and is arranged on the iron core rear portion, on iron core between the extension of middle part, and each dividing plate height is all more than or equal to upwardly extending extension top and to vertical distance between the extension bottom of downward-extension.
Described a kind of three-phase transformer structure is characterized in that: described dividing plate is rectangular clapboard.
The utility model is the winding around winding on the extension of iron core, wherein the extension at middle part staggers with the extension bearing of trend of front and rear portions respectively, and between front, middle part extension and between rear, middle part extension, dividing plate is set, can effectively prevent the problem of phase mutual interference between coil, improve the transformer job stability.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.a kind of three-phase transformer structure, include the iron core 1 of strip, the front portion of iron core 1, both sides, rear portion sidewall forms respectively the extension 2 that extends straight down, 3, both sides, the middle part sidewall of iron core 1 forms respectively the extension 4 that extends straight up, be wound with respectively coil windings 5 on each extension, also include the dividing plate 6 of a pair of rectangle of being made by exhausted magnetic material respectively, two dividing plate 6 centers are respectively equipped with the installation through hole, one of them dividing plate is installed through hole by center and is arranged on iron core 1 front portion, on iron core 1 between the extension of middle part, another dividing plate is installed through hole by center and is arranged on iron core 1 rear portion, on iron core 1 between the extension of middle part, and each dividing plate 6 is highly all more than or equal to upwardly extending extension top and to vertical distance between the extension bottom of downward-extension.
