Abstract
The utility model discloses a transformer low voltage rise seat is connected with ring flange and lower flange dish in that the aluminum alloy barrel is suitable for reading, goes up the ring flange middle part and leaves circular installing port, and the ring flange surface is gone up to installing port edge protrusion and leave installing port seal groove and installing port screw on the edge, has the outlet last ring flange dorsal part ann, and it has hole, handle hole and the fuel tap hole of exhaust to pacify on the aluminum alloy barrel, leaves handle hole seal groove and screw hole on the handle hole ring flange. This seat preparation simple process that risees, the convenience of getting the raw materials ready, the installation operation of being convenient for, it is still sealed effectual simultaneously, be difficult to outside oil leak and seep water to inside.
Description
Technical field
The utility model relates to transformer technology field, in particular to a kind of rising seat for transformer low voltage large current position.
Technical background
At present, on China's transformer industry high voltage large capcity power transformer, raise in the making of seat about low-voltage, high-current, what usually adopt is low magnetic steel plate and welds the structure of copper coin, solves with this local overheating phenomenon that stray field causes.This kind of structure difficulty of processing is large, raises seat welding operation difficulty large, easily causes seepage, more importantly can not realize comprehensive shielding for big current leakage field.This rising seat material cost is high, makes complicated, raises seat own wt large, installs inconvenient.In order to overcome these problems, utility model patent 200720138422.0 discloses a kind of individual layer cylindrical shell adopting aluminum alloy materials to make and raises seat, is combined by upper and lower adpting flange and aluminium alloy cylindrical body.This rising seat solves low magnetic steel plate and to get the raw materials ready difficult problem, simplifies manufacture craft, improves operating environment.But in actual use, this patent raises seat and also exists poorly sealed, and easy leakage of oil can not discharge the problems such as easy internally seepage in time at rainy day rainwater simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of transformer low voltage and raises seat, and this rising seat manufacture craft is simple, gets the raw materials ready conveniently, is convenient to fitting operation, and good sealing effect, is not easy outside leakage of oil and internally seeps water simultaneously.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of transformer low voltage raises seat, comprise aluminium alloy cylindrical body, be connected with upper flange plate aluminium alloy cylindrical body is suitable for reading, upper flange plate edge leaves upper bolt aperture, aluminium alloy cylindrical body end opening is connected with lower flange, lower flange edge leaves lower screw hole, it is characterized in that, circular mounting mouth is left in the middle part of described upper flange plate, installing port edge protrudes upper flange plate surface and on edge, leaves installing port seal groove and installing port screw, be equipped with spilled water hole at upper flange plate dorsal part and be communicated to upper flange plate upper surface, aluminium alloy cylindrical body is equipped with steam vent, handle hole and fuel tap hole, handle hole is suitable for reading is equipped with handle hole ring flange, handle hole ring flange leaves handle hole seal groove and screw hole.
Preferably, described handle hole has two or three, and is dispersed in around aluminium alloy cylindrical body in level.
The beneficial effects of the utility model are, adopt the structure of original upper lower flange connecting aluminum alloy cylindrical body, and important improvement has been made to details, in order to overcome leakage of oil, installing port edge is made to protrude upper flange plate surface and on edge, leave installing port seal groove, on handle hole ring flange, leave handle hole seal groove simultaneously, effectively like this enhance sealing effectiveness, upper flange plate dorsal part is equipped with spilled water hole and is communicated to upper flange plate upper surface simultaneously, effectively can drain the precipitation on upper flange plate surface, prevent accumulate and to seepage in transformer, also steam vent is set on aluminium alloy cylindrical body, effectively can discharge internal gas, keep inside and outside air pressure balance.
Accompanying drawing explanation
Fig. 1 the utility model angle perspective view;
Another angle perspective view of Fig. 2 the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, this transformer low voltage raises in seat, aluminium alloy cylindrical body 1 adopts individual layer aluminum alloy materials to make, and on the cylindric or straight shape cylinder of single straight shape, the oblique cylinder that connects again combines, accompanying drawing is the oblique situation connecting cylinder again and combine on straight shape cylinder.Be connected with upper flange plate 2 aluminium alloy cylindrical body 1 is suitable for reading, end opening connects lower flange 3, and upper flange plate edge leaves a circle upper bolt aperture 4, and lower flange leaves a circle lower screw hole 13.In the middle part of upper flange plate, leave circular mounting mouth 20, this installing port is for installing transformer internal wiring parts.The edge 6 of installing port protrudes upper flange plate surface and on edge, leaves installing port seal groove 8 and installing port screw 7, protrude surface to prevent the rain leakage on surface from entering inside, sealing ring can be put in installing port seal groove 8, be conducive to that seal is installed thereon and carry out effective sealing, both can prevent the cold oil in transformer from leaking outside, and also effectively prevent the water of outside from inwardly infiltrating.Be equipped with spilled water hole 15 at upper flange plate 2 dorsal part, this spilled water hole 15 is communicated to upper flange plate upper surface and forms discharge outlet 5, and rainwater leaks down through discharge outlet 5, prevents from accumulating on upper flange plate surface.Aluminium alloy cylindrical body 1 is equipped with steam vent 14 and is communicated to aluminium alloy cylindrical body inside, be convenient to discharge internal gas, make inner and outer air pressure keep balance.Aluminium alloy cylindrical body 1 is equipped with fuel tap hole 18, the ring flange on its surface leaves screw hole 19, to be connected with valve with the pipeline of outside.Simultaneously, aluminium alloy cylindrical body 1 also leaves one, two or three handle holes, this example is three handle holes, be respectively handle hole 9, handle hole 16 and handle hole 17, handle hole ring flange is connected with outside handle hole 9, it leaving handle hole seal groove 10, also leaving a circle screw hole 11, for being sealed by handle hole after workman's fitting operation completes around.Two other handle hole also leaves handle hole seal groove and screw hole.These three handle holes are that level is dispersed in around aluminium alloy cylindrical body, greatly facilitate installation.
The present embodiment just to the utility model design and explanations realizing, is not limited, and under the utility model design, the technical scheme converted without essence is still in protection range.
