Abstract
The utility model relates to a mining flameproof dry type transformer, comprising a flameproof shell body and a dry type transformer arranged in the flameproof shell body, wherein two sides of an upper iron yoke and a lower iron yoke of the transformer are respectively and correspondingly provided with U-steel clamping pieces in a fixedly clamping way, and openings of the U-steel clamping pieces are arranged outwards; insulation boards are arranged between the iron yokes and the U-steel clamping pieces; and the upper and the lower iron yokes and the U-steel clamping pieces which are respectively arranged at the front and the back sides of the upper and the lower iron yokes are correspondingly fixed together by winding insulation ribbons along the peripheral direction. Not only the whole structure of the dry type transformer is simpler and more compact, but also the binding is more stable and reliable because of adopting the fastening flexible connection of the insulation ribbons; the utility model can avoid the multipoint grounding problem of the iron core, which is caused by insulation breakdown because the iron core is directly contacted with a U-shaped screw; and meanwhile, the production process is simpler and additional production equipment is not needed. The dry type transformer is fixed in the flameproof shell body by the U-steel clamping pieces and a fixed seat on the inner wall of the flameproof shell body, and thereby greatly reducing the inner space and dimension of the flameproof shell body.
Description
Technical field
The utility model relates to a kind of flameproof dry type transformer.
Background technology
At present, existing flameproof dry type transformer or mobile substation, its transformer body is clamped in the flame proof housing and requires to have certain space constraint and stability.The disclosed flameproof dry type transformer Iron Core Clamping Device of Chinese patent ZL200820300652.7 comprises the iron yoke of transformer, the above and below of iron yoke is equipped with the clamping crossbeam, the both sides that clamp crossbeam are provided with flat support plate, be mounted with the U type screw rod of tightly locking connection by nut on the flat support plate, the U type screw rod on the iron yoke above and below clamps transformer core by connecting no latitude glass tape.Because this device needs load U type screw rod, not only need increase the operation of one punching, comparatively to waste time and energy, unshakable in one's determination directly the contact with U type screw rod also more easily causes damage in insulation to cause the problem of multipoint earthing unshakable in one's determination; Simultaneously, this device makes that also its overall structure is bigger, thereby has strengthened the inner space of dividing plate housing and the overall dimension of housing.
The existing method that clamps iron core also has by extra clamping device, the tension steel band of use pad insulation board is realized, but this structure is comparatively complicated, has not only increased production cost, because the mining equipment environment for use is moist unusually, steel band or take-up device are also than easy-to-rust.
The utility model content
The purpose of this utility model provides a kind of simple in structure, flameproof dry type transformer that colligation is firm and convenient for production.
For achieving the above object, the utility model adopts following technical scheme:
A kind of flameproof dry type transformer, comprise flame proof housing and inner dry-type transformer thereof, the corresponding respectively geometrical clamp in the both sides of the upper and lower iron yoke of transformer is provided with opening channel-section steel folder outwardly, be equipped with insulation board between iron yoke and the channel-section steel folder, the channel-section steel folder of described upper and lower iron yoke and both sides, front and back thereof is by the insulation silk ribbon in circumferential winding respective fixation together.
Described insulation silk ribbon is no latitude glass tape.
Described no latitude glass tape is fixed with one respectively by the folder of hot curing with upper and lower iron yoke and both sides correspondence thereof.
All offer silk ribbon on the described channel-section steel folder by groove, described no latitude glass tape by this silk ribbon by groove with the channel-section steel folder colligation of iron yoke and both sides thereof together.
Described dry-type transformer directly is fixed in the flame proof housing by the holder with channel-section steel folder corresponding matching that is provided with on channel-section steel folder both ends and the flame proof inner walls.
The position of described channel-section steel folder between no latitude glass tape and holder is provided with guide vane end stop.
The inboard of described channel-section steel folder is provided with reinforcement.
On of the present utility model, the channel-section steel folder of lower yoke and both sides, front and back thereof is by the insulation silk ribbon in circumferential winding respective fixation together, not only the overall structure of this dry-type transformer is comparatively simple compact, owing to adopt fastening being flexible coupling of insulation silk ribbon, also make colligation comparatively solid and reliable, avoided unshakable in one's determination and directly contacted the problem that more easily causes damage in insulation to cause multipoint earthing unshakable in one's determination with U type screw rod, simultaneously make that also production process is also comparatively easy and need not extra production equipment. in addition, the insulation silk ribbon is no latitude glass tape, no latitude glass tape will be gone up by hot curing, the folder of lower yoke and both sides correspondence thereof closely clamps and forms one, can not occur relaxing, the phenomenon of bounce-back, not only strengthened whole mechanical strength, no-load loss and noise have been reduced, and making easy to operately, production cost is lower; Offer silk ribbon on the channel-section steel folder by groove, no latitude glass tape makes the colligation fixed-site of no latitude glass tape by this silk ribbon by groove with the channel-section steel folder colligation of iron yoke and both sides thereof together, and colligation is more firm firmly; Dry-type transformer directly is fixed in the flame proof housing by the holder with channel-section steel folder corresponding matching that is provided with on channel-section steel folder both ends and the flame proof inner walls, not only effectively saved the inner space of flame proof housing, reduce the overall dimension of flame proof housing, also reduced production cost; The position of the bottom of channel-section steel folder between no latitude glass tape and holder sides adjacent is provided with guide vane end stop, this guide vane end stop can prevent with flameproof transformer in the process of flame proof housing internal fixation, the angle rib of holder will not have the latitude glass tape and scratches and cut off; The channel-section steel folder is provided with reinforcement, has strengthened the support strength of channel-section steel folder.
