Abstract
The utility model relates to a winding transformer with an elliptical section for a mine and a mobile substation provided with the transformer, and comprises a three phase iron core, and a high voltage winding and a low voltage winding which are sleeved on each iron core pole. A flame-proof shell body is arranged outside of the transformer. The low voltage winding is wound by the foil and arranged on the core pole of the three phase iron core, the shape of the cross section is close to an ellipse. Due to adopting the structure, compared with the prior art, the utility model has the advantages that the performance of the transformer and the production efficiency are improved, the cost is lowered, the product volume is reduced, etc. The utility model has the mobile substation that a high voltage switch and a low voltage switch are arranged on both sides of the flame-proof shell body, the mobile substation can be moved according to the requirements, and can be used in a coal mine conveniently.
Description
Technical field
The utility model relates to a kind of mining oval cross section coil transformer and has the mobile substation of this transformer.
Background technology
At present, most of mining transformer factory all adopts multistage circular cross-section laminated iron core to make transformer.Therefore, the shape of its coil also must be circular.Simultaneously, the structure of its low-voltage coil is that its mechanical strength of wire wound is lower, and production efficiency is low.And cause the duty ratio of transformer in circular flame proof housing relatively poor, and make the volume of product bigger, cost is higher.
The utility model content
Deficiency at the prior art existence, a kind of transformer performance that improves of providing is provided the purpose of this utility model, enhance productivity, reduce cost, reduce small product size and easily manufactured mining oval cross section coil transformer and have the mobile substation of this transformer.
For achieving the above object, the technical solution adopted in the utility model is:
1, a kind of mining oval cross section coil transformer, comprise three-phase iron core and the high and low pressure coil that is enclosed within on each core limb, the described transformer outside is provided with a flame proof housing, it is characterized in that: described low-voltage coil is with the foil coiling and is installed on the three-phase core limb that it is oval that its shape of cross section is approximately.It is oval that the shape of cross section of the stem of described three-phase iron core and iron yoke is approximately.
2, the high and low pressure switch is installed in a kind of mobile substation that has above-mentioned mining oval cross section coil transformer in flame proof housing both sides.
3, at described flame proof housing bottom mobile device is installed.
4, as further improvement of the utility model, above-mentioned mobile device can be roller.
The beneficial effects of the utility model are:
Because adopt said structure, the utility model compared with prior art has the raising transformer performance, enhances productivity, and reduces cost, reduce small product size and advantage such as easily manufactured.
Employing has the mobile substation of this transformer, can move as required, very conveniently uses in the colliery.
Description of drawings
Fig. 1 is the cutaway view of the utility model mobile substation.
Fig. 2 is the iron core and the coil section figure of the utility model transformer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1 iron core
2 low-voltage coils, 3 high-tension coils
4 flame proof housings, 5 high-voltage switch gears
6 rollers, 7 low tension switches
As Fig. 1, shown in Figure 2, a kind of mining oval cross section coil transformer comprises three-phase iron core and the high and low pressure coil that is enclosed within on each core limb.The described transformer outside is provided with a flame proof housing.Described low-voltage coil is with the foil coiling and is installed on the three-phase core limb that it is oval that its shape of cross section is approximately.It is oval that the stem of described three-phase iron core and the cross section of yoke are approximately.
In the described transformer outside flame proof housing is installed, is applicable to explosive gas atmosphere.This flame proof housing can bear the pressure that internal explosion produces, and can stop again because internal explosion causes flame proof housing combustible gas explosion on every side.
As shown in Figure 1, the high and low pressure switch is installed in a kind of mobile substation that has above-mentioned mining oval cross section coil transformer in described flame proof housing both sides.Described high and low pressure switch is connected by lead-in wire with the high and low pressure coil of described transformer.
At described flame proof housing bottom roller is installed, makes transformer station overcome the form that routine is fixed on a place, can move as required, conveniently in the colliery, use.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present utility model.Though but on its shape or structure, do any variation, every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
