The utility model discloses reducible transformer oil's quantity reduces transformer manufacturing cost to the location is simple, and simple to operate has still strengthened oil tank inner structure's steadiness, and under the abominable condition of weather, can avoid the junction of box and case lid to be drenched by the rainwater to guarantee transformer tank's normal work has been avoided during the rainwater leaks into the box.
Description
Technical field
The utility model relates to field transformer, particularly a kind of fuel tank of oil-filled transformer.
Background technology
At present, the casing of distribution transformer fuel tank is generally rectangular box, and the upper and lower structure of casing is consistent, and transformer body needs to be arranged in oil tank of transformer by locating pin usually.When transformer body is assembled in fuel tank, transformer oil lower box part has many spaces, causes the increase of transformer oil use amount.The mode of existing this technical barrier of solution is the lattice plate being welded into L-shaped in fuel tank with two block plates, with the lattice plate of two pieces of L-shaped, tank bottoms is arranged to convex-down again, but adopt this kind of method just to there is a problem, the L-shaped lattice plate be welded into by two block plates needs to bear the pressure of transformer oil in fuel tank, and the shaking force that equipment drives fuel tank need be born, because the strong point of lattice plate is less, be easy to occur to come off because of the pad between steel plate or between steel plate and oil tank wall, steel plate fractureed and drops in the seal cavity of fuel tank both sides; And oil tank of transformer majority is all arranged on open air, usually to face various atrocious weather environment, if rainwater leaks into oil tank of transformer, can produce a very large impact the performance of transformer, even cause power supply trouble.
Summary of the invention
The purpose of this utility model is just to provide a kind of fuel tank of oil-filled transformer, reduce the use amount that box house redundant space also saves transformer oil simultaneously, also strengthen the steadiness of right-angle side in casing simultaneously, and further improve the water resistance of casing.
Technical problem of the present utility model is solved mainly through following technical proposals:
A kind of fuel tank of oil-filled transformer, comprise casing and case lid, opening is provided with above described casing, this body side is provided with fin, the edge of described case lid all forms kink to downward-extension, described case lid is bolted on open top, describedly be bolted on the sidewall of casing, the right-angle side that the equal seal weld in both sides, long edge position of the bottom in described casing is connected to steel plate bending or is welded into, described right-angle side is made up of top margin and side, bottom in described casing is also provided with positioning strip, the narrow end of described bottom half and fixed support fastening.
Preferably, supporting bracket is equipped with by two seal cavities that right-angle side and cabinet wall are formed in described casing, and the supporting bracket quantity in each seal cavity is all no less than three pieces, polylith supporting bracket is evenly arranged along the minor face of casing inner bottom part, the two ends up and down of described supporting bracket respectively with bottom top margin and bottom half fixedly weld.
Preferably, sealing ring is provided with between described casing and case lid.
Preferably, described positioning strip quantity is no less than two, and many positioning strips are all between two groups of sides.
Preferably, described case lid upper surface is provided with suspension ring.
The beneficial effects of the utility model are: the utility model can reduce the consumption of transformer oil, reduce transformer production cost, and location is simple, easy for installation, also enhance the steadiness of fuel tank internal structure; And when bad weather, kink and sealing ring can stop outside rainwater and sand and dust, avoid the junction of casing and case lid to be drenched by rainwater, thus avoid in rainwater leakage inlet body, further reduce the possibility that casing leaks, ensure the normal work of oil tank of transformer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1, casing, 2, case lid, 3, fin, 4, kink, 5, bolt, 6, right-angle side, 7, top margin, 8, side, 9, positioning strip, 10, fixed support, 11, supporting bracket.
Embodiment
Below by embodiment, and 1-2 by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of fuel tank of oil-filled transformer, comprise casing 1 and case lid 2, opening is provided with above described casing 1, this casing 1 side is provided with fin 3, the edge of described case lid 2 all forms kink 4 to downward-extension, described case lid 2 is fixed on open top by bolt 5, described bolt 5 is fixed on the sidewall of casing 1, the right-angle side 6 that the equal seal weld in both sides, long edge position of the bottom in described casing 1 is connected to steel plate bending or is welded into, described right-angle side 6 is made up of top margin 7 and side 8, bottom in described casing 1 is also provided with positioning strip 9, narrow end bottom described casing 1 and fixed support 10 fastening.
Preferably, supporting bracket 11 is equipped with in two seal cavities be made up of right-angle side 6 and casing 1 inwall in described casing 1, and supporting bracket 11 quantity in each seal cavity is all no less than three pieces, polylith supporting bracket 11 is evenly arranged along the minor face of casing 1 inner bottom part, and the two ends up and down of described supporting bracket 11 are fixedly welded respectively with bottom top margin 7 and bottom casing 1.
Seen from the above description, supporting bracket 11 strengthens the steadiness of right-angle side 6, meanwhile, also further enhances right angle, 6 bear pressure.
Preferably, sealing ring is provided with between described casing 1 and case lid 2.
Seen from the above description, sealing ring can make casing 1 better with the sealing property of case lid 2.
Preferably, described positioning strip 9 quantity is no less than two, and many positioning strips 9 are all between two groups of sides 8.
Seen from the above description, it is convenient that positioning strip 9 can make transformer body be installed in fuel tank, more firmly.
Preferably, described case lid 2 upper surface is provided with suspension ring.
