Abstract
A mining flameproof transformer and a mobile substation provided with same relate to transformers and solve the problems that the upper part and the lower part of a transformer shell have large temperature difference, so the cooling function of the shell cannot be given a full play; the lower part of the shell easily generates a condensation phenomenon which can cause corrosion to the lower part of the shell and further shortens the service life of the transformer; and the design of the transformer is difficultly optimized due to limit of underground haulage roadways. A three-phase wound iron core is of a three-dimensional triangular wound iron core shape and is horizontally arranged in a flameproof shell, a low-tension coil is wound on a three-phase wound iron core column, and a high-tension coil is wound on the low-tension coil. The mining flameproof transformer and the mobile substation provided with the mining flameproof transformer have the advantages of reasonable structure, more excellent property and remarkable energy-saving effect; due to adoption of the horizontal structure, temperature difference between the upper part and the lower part of the flameproof shell is reduced, the effective cooling area of the flameproof shell is greatly increased, so that the temperature of the lower part of the flameproof shell is increased and the condensation phenomenon is avoided; and the design of the transformer can be optimized as required.
Description
Technical field
The present invention relates to field transformer, be specifically related to the flame-proof mine transformer and have the mobile substation of this transformer.
Background technology
At present; The most factories of China all adopt traditional planar structure laminated core technology to make flame-proof mine 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 have the mobile substation of this transformer " of ZL200620148455.9 solved the problems referred to above.Yet also there are following point in existing flame-proof type 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 flame proof housing, corrode lower housing portion thus and cause shorten useful life; Limited by the down-hole haulage drift, transformer is difficult to optimal design.
Summary of the invention
The invention solves the following point that existing flame-proof mine transformer and mobile substation exist: 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 flame proof housing, corrode lower housing portion thus and cause shorten useful life; Limited by the down-hole haulage drift, transformer is difficult to optimal design.A kind of flame-proof mine transformer is provided and has had the mobile substation of this transformer, the concrete technical scheme that addresses this problem is following:
Flame-proof mine transformer of the present invention and have the mobile substation of this transformer; Comprise flame proof housing, three-phase volume iron core, high-tension coil and low-voltage coil; Described three-phase volume iron core is 3-D triangle volume iron core shape; Be horizontally set in the flame proof housing, 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 made up 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 constitute three-phase stereo triangle volume.
Flame-proof mine transformer of the present invention and to have the 3-D triangle that the mobile substation of this transformer adopts unshakable in one's determination; Roll 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 of 3-D triangle Wound iron-core transformer is symmetry equivalent fully, and the iron yoke is the shortest, is the most desirable electric power transformer device structure 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 3-D triangle rolls up power transformer each item test data unshakable in one's determination and be superior to plane power transformer unshakable in one's determination, has reached low-carbon economy and energy-saving and emission-reduction requirement of products; The 3-D triangle Wound iron-core transformer adopts horizontal type structure, and the flame proof housing top and the bottom temperature difference is reduced, and flame proof housing efficiently radiates heat area increases greatly; Because flame proof lower housing portion temperature raises, and the condensation phenomenon is no longer occurred, and has improved the useful life of mining dry-type transformer; The transformer optimal design no longer receives the underworkings transport restrictions, is more suitable for the advantage of using under the mine.The present invention is applicable to that flame-proof mine transformer, flameproof mining mobile transformer substation, flame-proof mine charger etc. have in other flame-proof mine product of three-phase transformer.
