Abstract
The utility model relates to a three phase five pole type iron core transformer for a mine, which comprises a three phase five pole ungrading type iron core and a high voltage winding and a low voltage winding which are sleeved on an A, a B, a C core poles. A flame-proof shell body is arranged outside of the transformer. The core pole of the three phase five pole ungrading type iron core is of a multilevel round section, an iron yoke and a side yoke are of multilevel elliptical sections. Under the condition having the height limit, the structure can further increase the limit capability of the transformer, and satisfy the requirement of supplying the power for the laneway in a coal mine. 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 three phase five pole type iron core transformer and has the mobile substation of this transformer.
Background technology
At present, most of mining transformer factory all adopts three phase three limb core to make transformer.Owing to stipulate that locomotive frame ceases to be busy height is not less than 1.9 meters under the mine in the safety regulations in coal mine of national security production supervision management board promulgation, under this situation about highly limiting, adopt its power-carrying of transformer of three phase three limb core manufacturing to be restricted.
The utility model content
Deficiency at the prior art existence, it is a kind of under the condition that highly limits that the purpose of this utility model is to provide, adopt the three phase five pole type iron core structure, can increase the power-carrying of transformer, satisfy coal mine roadway power supply requirement mining three phase five pole type iron core 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 three phase five pole type iron core transformer comprises three-phase and five-pole laminated iron core and the high and low pressure coil that is enclosed within on A, B, three stems of C.The described transformer outside is provided with a flame proof housing.The A of three-phase and five-pole laminated iron core, B, three stems of C are multistage circular cross-section, and yoke and two return yokes are multistage elliptic cross-section.
2, the high and low pressure switch is installed in a kind of mobile substation that has above-mentioned mining three phase five pole type iron core 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.
Three-phase and five-pole laminated iron core structure is by three stems, and upper and lower iron yoke and two return yokes are formed, and wherein put the high and low pressure coil at A unshakable in one's determination, B, three stems of C.A, B, three heart column sections of C are multistage circle, and the cross section of iron yoke and return yoke is multistage ellipse.Know the magnetic flux φ of iron yoke according to magnetic flux phase magnitude relation
1Be stem magnetic flux φ
A0.577 times promptly
φ
1＝0.577×φ
A
Compare with the upper and lower yoke height of common three-phase three-column iron core, the upper and lower yoke height of three-phase and five-pole laminated iron core is the former 0.577 times.
The utility model has reduced the total height of transformer significantly owing to adopted three-phase and five-pole laminated iron core structure.If under equal height requires, can make more jumbo transformer.To have satisfied the needs of powering in the mine.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1 high-voltage switch gear 2, iron core
3 high and low pressure coils 4, flame proof housing
5 low tension switches 6, roller
As Fig. 1, shown in Figure 2, a kind of mining three phase five pole type iron core transformer comprises three-phase and five-pole laminated iron core and the high and low pressure coil that is enclosed within on A, B, three stems of C.The described transformer outside is provided with a flame proof housing.The A of three-phase and five-pole laminated iron core, B, three stems of C are multistage circular cross-section, and yoke and two return yokes are multistage elliptic cross-section.This structure can further increase transformer capacity under situation about highly limiting.
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 flammable gas explosion on every side.
The high and low pressure switch is installed in a kind of mobile substation that has mining three phase five pole type iron core transformer in described flame proof housing both sides.Described high and low pressure switch is connected with the lead-in wire of 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 can only be fixed on a place, can move as required, conveniently in the colliery, use.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter 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.
Claims (4)
