Abstract
A kind of oil immersed transformer fuel tank cover, it is hierachical structure, and rectangle case lid main body surrounding is distributed several bolts hole；The big boss in inclined-plane is set as among case lid main body, the big boss surrounding in inclined-plane there are rounded corners；It is plane on the big boss in inclined-plane, several wiring through-holes of punching press in plane mill out circular seal slot around through-hole at 2 3mm；Rectangle case lid body edge edge is to lower hem, and rectangular body surrounding has rounded corner, rectangle case lid lower body facing cut to go out rectangle seal groove.The big boss in inclined-plane has played the role of reinforcing rib, increases the intensity of case lid, and when lifting is unlikely to deform；The big boss in inclined-plane is easier to drain, and rubber seal can be put into seal groove, plays waterproof action for top-portion apertures, avoids the breakdown accident caused by infiltration, it is ensured that transformer safety is run.The seal groove in case lid lower body face prevents the infiltration of threaded hole, case lid body edge from preventing damage of the solar radiation to sealing ring along that rainwater can be prevented into cartonning edge to lower hem.
Description
Technical field
The utility model is related to oil-immersed transformer technical fields, and in particular to a kind of oil immersed transformer fuel tank cover.
Background technology
The case lid of oil immersion-type distribution transformer fuel tank generally used now is in plane hood configuration, and four side of case lid is welded for bending
Made of side, when case lid is connect with fuel tank, connected with fastener.This structure the problem is that：The mechanical strength of case lid is not
It is enough, deformation is easy tod produce when case lid and fuel tank lift by crane, plane forms ponding, so that water is easily penetrated into fuel tank, influence insulating properties,
Breakdown accident is caused, and influences service life and the use of transformer.
Invention content
In order to overcome above-mentioned disadvantage of the existing technology, the purpose of this utility model is to provide it is a kind of it is easy to make,
The oil immersed transformer fuel tank cover of function admirable.
The technical solution adopted in the utility model is as follows：
A kind of oil immersed transformer fuel tank cover, sets that there are one the big boss in inclined-plane, the big boss tops in inclined-plane among case lid main body
Face is equipped with several small wiring holes and several big wiring holes；It is equipped with seal groove, seal groove around small wiring hole and big wiring hole
Middle setting sealing ring；Case lid lower body face also is provided with seal groove, and sealing ring is arranged in seal groove.Above-mentioned oil-immersed transformer oil
Case case lid is for covering oil tank for oil immersion type transformer, and the big boss in inclined-plane is convenient for draining, and sealing ring is for preventing water from penetrating into case
In vivo.
Preferably, the quantity of small wiring hole is four, and the quantity of big wiring hole is three.
Further, case lid body rim is equipped with downward flanging, reinforces waterproof effect.
Further, case lid main body is surrounded by several bolt holes.The quantity of bolt hole is arranged on demand, make its with
Bolt hole on oil tank for oil immersion type transformer corresponds to.After case lid covers on oil tank for oil immersion type transformer, in bolt hole interpolation
Enter bolt, case lid is fastened by bolt and oil tank for oil immersion type transformer.
Further, the quadrangle of case lid main body is fillet.
Further, the big boss in inclined-plane is surrounded by knuckle.
Preferably, above-mentioned oil immersed transformer fuel tank cover uses Steel Sheet and groove milling.
The utility model has the beneficial effects that：Oil immersed transformer fuel tank cover uses hierachical structure, in case lid main body
Between be equipped with the big boss in inclined-plane, strengthen the mechanical strength of case lid, be not likely to produce deformation, be easy drain；Case lid main body inclined-plane is convex greatly
It is plane above platform, is equipped with several wiring punching press through-holes, is equipped with circular seal ring around through-hole, prevents the water around wiring hole from oozing
Enter to babinet；Case lid has downwards flanging, prevents water from penetrating into fuel tank, moreover it is possible to prevent damage of the light radiation to sealing ring, extend
Service life.It is molded using steel plate punched, this hierachical structure is easy to make without welding, efficient, and can improve
The safe to use and service life of transformer.It is compact-sized, and quadrangle is fillet, it is beautiful.

Specific implementation mode
Below against drawings and examples, specific embodiment of the present utility model is described.
As shown, a kind of oil immersed transformer fuel tank cover, is molded using steel plate punched, drilling and groove milling.This change
Depressor fuel tank case lid is layered structure, sets the big boss 4 in an inclined-plane among case lid main body, the top surface setting three of the big boss in inclined-plane 4
A big wiring hole 6 and four small wiring holes 7, three big wiring hole 6 and four small wiring holes 7 are through-hole, three big wiring hole 6
It is equipped with seal groove 8 at surrounding 2-3mm, seal groove 9 is equipped at four 7 surrounding 2-3mm of small wiring hole；Case lid main body surrounding
The flanging 3 downward along setting；A circle (bolt hole 1 in the present embodiment of bolt hole 1 is arranged at flanging in case lid main body
Quantity is 38)；Case lid lower body face also is provided with seal groove 10.
When making, the flanging 3 and fillet 2 of case lid main body are first stamped out, then stamp out the big boss 4 in inclined-plane on the basis of this and fall
Then fillet 5 drills out bolt hole 1, big wiring hole 6 and small wiring hole 7 with drilling machine on this basis, then milled out respectively with milling machine close
Sealing groove 8,9,10.Electro-insulating rubber circle or sheet rubber are put in seal groove 8,9,10, completely cut off the infiltration of rainwater at wiring hole so that into one
Waterproof is walked, more ensures that transformer is safe to use and the service life.
The utility model is not limited to above-described embodiment, within the knowledge of those skilled in the art, may be used also
With the various change made under the premise of not departing from this utility model and conceiving.
