Description
(1) technical field
The utility model relates to a kind of hermetically-sealed construction, particularly a kind of transformer oil storage flange sealing structure.
(2) background technology
Along with the increase of power consumption, electric system is more and more huger, and station service power number transformer also gets more and more, and for power consumer, its maintenance workload is corresponding increase also.In capsule type oil storage cabinet assembling and use procedure, there is capsule fold sometimes, capsule encases oil level gauge float, the fuel level gage vacation situation such as oil level, capsule failure analysis, need the flange opening oil conservater end, capsule, oil level gauge float are checked.Consider the factors such as oil conservater manufacturing process in the past, usually one end cover plate of oil conservater is welded on oil conservater, cover plate is fixed on the flange of oil conservater end by other end mode with bolts, to carry out the sealing of oil conservater, but along with the increase of oil conservater diameter and the raising to oil conservater requirement of mechanical strength, its oil conservater flange plate diameter also increases thereupon and thickness also needs to thicken, namely the weight of cover plate adds, again because oil conservater is arranged on the top of voltage transformer, overhead higher, oil conservater for high potential product operates, belong to aloft work category, so, along with the increase of oil conservater diameter and the raising of house transformer voltage class, the large flange cover plate of oil conservater end is utilized to carry out overhauling, safeguarding capsule and oil level gauge etc., inconvenience will be brought, such as: sometimes will employ hoisting crane, dismounting oil level gauge rainproof cover, dismounting oil level gauge signal wire (SW) etc., therefore need to improve transformer oil storage flange sealing structure.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of rational in infrastructure, practical, the transformer oil storage flange sealing structure that installation and repairing is simple, quick and easy.
The utility model is achieved by the following technical solution:
A kind of transformer oil storage flange sealing structure, comprise main cover plate and main flange, it is characterized in that: described main flange is connected with oil conservater, main cover plate and main flange are fixed by fastener, lay sealing member between main cover plate and main flange; Be provided with manhole in the middle part of described main cover plate, this manhole top is provided with secondary flange; Described secondary flange and main bridge welding are connected together; Described secondary flange top is provided with seal groove, lays sealing member in sealing groove; Described secondary flange is stamped auxiliary coverplate, and this auxiliary coverplate and secondary flange are fixed by fastener; Described auxiliary coverplate is provided with handle.
On described main cover plate, manhole two ends are respectively equipped with suspension ring and fuel level gage mounting hole.
Described people's bore dia is 500mm.
Described secondary flange internal diameter 470mm, external diameter 560mm, thickness 25 ㎜.
The utility model avoids oil conservater capsule, oil level gauge etc. carrying out installing, inspection and maintenance time dismounting oil conservater end main cover plate, only need to open with auxiliary coverplate, both can be operated above-mentioned work by manhole, and to the saving repair time, avoid the generation of safety misadventure significant; In addition, the utility model is welded with carrying, switching and handle easy to assembly on auxiliary coverplate, makes oil conservater capsule, oil level gauge etc. carrying out installing, inspection and maintenance is more simple, quick.
The utility model is rational in infrastructure, practical, and installation and repairing is simple, quick and easy, is useful on all capsule-types of diameter >=1000 ㎜, diaphragm type and outer oily corrugated pipe oil tank and applies.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
