Abstract

The utility model relates to a dry type single phase power transformer, comprising an iron core 1, a coil winding and an outer insulator 2. The coil winding is made up of an A phase high and low voltage winding 3 and a B phase high and low voltage winding 4; the A phase high and low voltage winding 3 and the B phase high and low voltage winding 4 are abreast arranged on the iron core 1 and then the outer insulator 2 is poured on the A phase high and low voltage winding 3 and the B phase high and low voltage winding 4. The utility model has the structure of that the transformer has small volume and compact structure; the utility model utilizes two single phase power transformers to realize three phase transforming, having the advantages of simple and convenient assembling, easy operation and high function price proportion.

Description

A kind of dry type single phase poaer supply transformer

1, technical field:

The utility model relates to a kind of dry type single phase poaer supply transformer.

2, background technology:

At present, using in electric power system often is three phase mains transformer or single phase poaer supply transformer, but the shortcoming of these power transformer structures is: the core structure complexity, and volume is big, and it is many to take up room, and installs and uses inconvenience, and manufacturing cost is higher.

3, summary of the invention:

In order to overcome the deficiencies in the prior art, it is little that the purpose of this utility model provides a kind of volume, simple and compact for structure rationally distributed, and functional price is than high a kind of dry type single phase poaer supply transformer.

The utility model is achieved by the following technical solution:

A kind of dry type single phase poaer supply transformer comprises iron core, coil windings and outer insulator, coil windings by A phase high-voltage coil and low-voltage coil and B mutually high-voltage coil and low-voltage coil form, A phase high-voltage coil and low-voltage coil and B be high-voltage coil and low-voltage coil and come on the iron core and then outer insulator is gone up in cast mutually.This structure, volume is little, compact conformation; Utilize the combination of two single phase poaer supply transformers just can realize the three-phase transformation, make up simple and convenient, processing ease, functional price compares height.

Above-mentioned described A phase high-voltage coil and low-voltage coil and B high-voltage coil and low-voltage coil mutually are enclosed within on the iron core, can further dwindle small product size, simplified structure.

Above-mentioned described iron core is hollow or day font.

Lug is stretched out in above-mentioned described outer insulator both sides, and lug has installing hole, installs and uses very convenient.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is a profile of the present utility model;

Fig. 2 is the A-A profile of Fig. 1.

5, embodiment:

As shown in Figure 1 and Figure 2, the utility model comprises iron core 1, coil windings and outer insulator 2, coil windings by A phase high-voltage coil and low-voltage coil 3 and B mutually high-voltage coil and low-voltage coil 4 form, A phase high-voltage coil and low-voltage coil 3 and B be high-voltage coil and low-voltage coil 4 and come on the iron core 1 and then outer insulator 2 is gone up in cast mutually.A phase high-voltage coil and low-voltage coil 3 and B high-voltage coil and low-voltage coil 4 mutually can be to be enclosed within on the iron core 1.Iron core 1 is hollow or day font, and lug 5 is stretched out in outer insulator 2 both sides, and lug 5 has installing hole 6.
