Abstract
The utility model provides a mining flameproof transformer and a mobile substation provided with the same and relates to transformers. The mining flameproof transformer and the mobile substation provided with the same solve the problems that a temperature difference in an upper shell and a lower shell of a transformer is excessive, and therefore a heat dissipation of the shells can not be fully developed; the lower portion is prone to condensation, and consequently the lower shell can be corroded and shortens the service life of the transformer; and being limited by underground transportation roadways, optimization design of the transformer is difficult. The mining flameproof transformer and the mobile substation provided with the same are characterized in that a three-phase wound iron core is of a triangle shape and horizontally arranged inside a flameproof shell, a low-voltage coil is wound on a stem of the three-phase wound iron core, and a high-voltage coil is wound on the low-voltage coil. The mining flameproof transformer and the mobile substation provided with the same have the advantages of being reasonable in structure, excellent in performance, and obvious in energy-saving. A horizontal structure is adopted, the temperature difference between the upper portion and the lower portion of the flameproof shell is reduced, the effective heat dissipation area of the flameproof shell is greatly increased, the temperature of the lower portion of the flameproof shell is raised, and the phenomenon of condensation can not happen. In addition, the transformer can be designed in optimized mode according to demands.
Description
Technical field
The utility model relates to field transformer, is specifically related to mining explosion-proof transformer and with the mobile substation of this transformer.
Background technology
At present, the most factories of China all adopt traditional planar structure laminated core technique to make mining explosion-proof transformer and mobile substation, there is the air seam to have the highly energy-consuming district owing to existing local flux direction and silicon steel sheet magnetic conduction direction many places inconsistent and unshakable in one's determination, magnetic resistance unshakable in one's determination is increased greatly, cause no-load current and no-load loss higher and running noises is bigger than normal, this type of transformer is broken through being difficult to aspect the power-saving technology lifting.The patent No. is that 01274757.2 " flame-proof mine Wound core mobile substation " and the patent No. are that " the mining three-phase wound core transformer and with the mobile substation of this transformer " of ZL200620148455.9 solved the problems referred to above.Yet also there are following point in existing Flameproof transformer and mobile substation: the three-phase magnetic loop is uneven; Because of housing top and the bottom excessive temperature differentials, can not give full play to the housing heat sinking function; Be prone to condensation when adopting cartridge type ripple explosion-proof casing, corrode lower housing portion thus and cause shorten useful life; Limited by the underground transportation tunnel, transformer is difficult to optimal design.
The utility model content
The utility model has solved the following point of existing mining explosion-proof transformer and mobile substation existence: the three-phase magnetic loop is uneven; Because of explosion-proof casing top and the bottom excessive temperature differentials, can not give full play to the housing heat sinking function; Be prone to condensation when adopting cartridge type ripple explosion-proof casing, corrode lower housing portion thus and cause shorten useful life; Limited by the underground transportation tunnel, transformer is difficult to optimal design.Provide a kind of mining explosion-proof transformer and with the mobile substation of this transformer, the concrete technical scheme that addresses this problem is as follows:
Mining explosion-proof transformer of the present utility model reaches the mobile substation with this transformer, comprise explosion-proof casing, three-phase volume iron core, high-tension coil and low-voltage coil, described three-phase is rolled up shape triangular in shape unshakable in one's determination, be horizontally set in the explosion-proof casing, low-voltage coil is wound on the three-phase volume stem stem unshakable in one's determination, and high-tension coil is wound on the low-voltage coil.
Described three-phase volume is unshakable in one's determination to be comprised of three identical single frame cores of structure, and the long limit of two adjacent single frame cores is fixed together by binding strap, and it is unshakable in one's determination to consist of three-phase stereo triangle volume.
The utility model mining explosion-proof transformer and the stereoscopic triangular iron core that adopts with the mobile substation of this transformer, rolled by continuous silicone steel band or non-crystaline amorphous metal strip and to form, need not cutting, punching, eliminated the horizontal and longitudinal seam of traditional transformer, reduced magnetic resistance.Because the three-phase magnetic loop full symmetric of three-dimensional triangular wound core transformer equates, and the iron yoke is the shortest, is the most desirable structure of power transformer of generally acknowledging, its more excellent performance, energy-conservation more remarkable, this is that the plane is unshakable in one's determination incomparable; Test shows that the every test data of stereo-triangular wound core power transformer is better than the plane core power transformer, has reached the requirement of low-carbon economy and energy-saving and emission-reduction product; Three-dimensional triangular wound core transformer adopts horizontal type structure, and the explosion-proof casing top and the bottom temperature difference is reduced, and explosion-proof casing efficiently radiates heat area increases greatly; Because the explosion-proof casing temperature of lower raises, and the condensation phenomenon is no longer occurred, and has improved the useful life of mining dry-type transformer; Optimum Design of Transformers no longer is subjected to the underworkings transport restrictions, the advantage that is more suitable for using under the mine.The utility model is applicable in other flame-proof mine products with three-phase transformer such as mining explosion-proof transformer, flameproof mining mobile transformer substation, flame-proof mine charger.
