Abstract
The utility model relates to a mining three-phase wound core transformer and a mobile substation with the transformer. The mining three-phase wound core transformer includes a three-phase wound core and high-voltage, low-voltage coils which are sleeved on each core column. The three-phase wound core is composed of an outer-ring core frame and two same inner-ring core frames which are nested mutually. The outside of the transformer is provided with an explosion proof shell body. The outer-ring core frame is formed by winding of a silicon steel belt which is narrow in one end, wide in the other end and even in the transition on the both sides from wide to narrow. The inner-ring core frames are respectively formed by winding of the same silicon steel belts from narrow to wide. The utility model has the advantages of good magnetic permeability, increased filling coefficient and material-saving etc. Such a structure can improve the performance of the transformer, reduce the no-load current and no-load loss, lower the noises and create the conveniences. The mobile substation is equipped with high-voltage, low-voltage switches at the both sides of the explosion proof shell body; thus the utility model can be moved according to the requirements, which is very easy to use in the coal mines.
Description
Technical field
The utility model relates to a kind of mining three-phase wound core transformer and has the mobile substation of this transformer.
Background technology
At present, most of mining transformer factory all adopts laminated iron core to make transformer.The cross section of laminated iron core stem and yoke is multistage circular cross-section, and its activity coefficient is about 90%.The seam unshakable in one's determination of this structure is more, duty ratio, production efficiency are low, causes no-load current and no-load loss and noise bigger than normal.The patent No. is that 01274757.2 " flame-proof mine Wound core phase shifting transformer " adopts a two narrow, middle wide silicon strip coiling, and it is circular that the cross sectional shape of its stem and yoke is approximately.This structure can only the single-phase wound core of coiled, can not the coiled stem and the shape of cross section of yoke be approximately circular three-phase wound core.
The utility model content
Deficiency at the prior art existence, the purpose of this utility model is to provide a kind of transformer performance that improves, and reduces no-load current, no-load loss, reduction noise, good energy-conserving effect and easily manufactured mining three-phase wound core transformer and has the mobile substation of this transformer.
For achieving the above object, the technical solution adopted in the utility model is a kind of mining three-phase wound core transformer, comprises three-phase wound formula iron core and the high and low pressure coil that is enclosed within on each core limb.Described three-phase wound formula iron core is by an outer ring iron core frame and two identical mutually nested compositions of inner ring iron core frame.The described transformer outside is provided with a flame proof housing.Described outer ring iron core frame is narrow by one one, and the silicon strip of a head breadth both sides even transition is formed to narrow coiling by wide.Described inner ring iron core frame is to be formed by outer ring iron core frame and two mutually nested three-phase wound cores that form of identical inner ring iron core frame by the coiling from narrow to wide of identical silicon strip respectively again, and it is circular that the cross section of its stem and yoke is approximately.
The high and low pressure switch is installed in a kind of mobile substation that has above-mentioned mining three-phase wound core transformer in flame proof housing both sides.
At described flame proof housing bottom mobile device is installed.
As further improvement of the utility model, above-mentioned mobile device can be roller.
The beneficial effects of the utility model are:
1, because the utility model adopts the outer ring iron core frame narrow by one one, and the silicon strip of a head breadth both sides even transition is formed to narrow coiling by wide, described two identical inner ring iron core frames are to be formed by the coiling from narrow to wide of identical silicon strip respectively.By described outer ring iron core frame and two mutually nested three-phase wound cores that form of identical inner ring iron core frame, it is circular that the cross section of its stem and yoke is approximately.It is good that the iron core of this structure has a magnetic property, and activity coefficient increases also saves material;
2, the high and low pressure coil directly on core limb coiling form, save mounting coil technology;
3, can improve the performance of transformer, reduce no-load current, no-load loss, reduce noise, good energy-conserving effect and 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 iron core and the coil assembly drawing of the utility model transformer.
Fig. 2 is the A-A cutaway view of the utility model transformer.
Fig. 3 is the structural representation of mobile substation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1 high and low pressure coil
2 flame proof housings, 3 outer ring iron core frames
4 inner ring iron core frames, 5 high-voltage switch gears
6 low tension switches, 7 rollers
As Fig. 1, shown in Figure 2, a kind of mining three-phase wound core transformer comprises three-phase wound formula iron core and the high and low pressure coil 1 that is enclosed within on each core limb.Described three-phase wound formula iron core is by an outer ring iron core frame 3 and two 4 mutually nested compositions of identical inner ring iron core frame.The described transformer outside is provided with a flame proof housing 2.Described outer ring iron core frame 3 is narrow by one one, and the silicon strip of a head breadth both sides even transition is formed to narrow coiling by wide.Described two identical inner ring iron core frames 4 are to be formed again by outer ring iron core frame 3 and two identical inner ring iron core frames, the 4 mutually nested three-phase wound cores that form by the coiling from narrow to wide of identical silicon strip respectively, the cross section of its stem and yoke is approximately circle and iron core, and to have a magnetic property good, and activity coefficient increases and saves advantage such as material.
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.
As shown in Figure 3, high and low pressure switch 5,6 is installed in described flame proof housing both sides in a kind of mobile substation that has above-mentioned mining three-phase wound core transformer, and described high and low pressure switch 5,6 is connected with the lead-in wire of the high and low pressure coil of described transformer.
In described flame proof housing 2 bottoms roller 7 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; 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.
