Description
Technical field
The utility model relates to a kind of high-voltage electrical equipment, relates in particular to the transformer in a kind of compound combined electrical equipment of integrated, miniaturization, the transformer station of the tail end line-transformer group connection type that is specially adapted to load.
Background technology
Development along with electrical network, the construction miniaturization of transformer station, intellectuality are inexorable trend, especially city or the city fringe regions of development, and the land resource of building transformer station is more and more nervous, whole nation electric power system all faces identical problem, is exactly the difficult problem of expropriation of land of transformer substation construction.
And in the prior art,, and by the design discipline regulation enough electrical distances and transport channel to be arranged between each electric equipment because the substation equipment kind is more, cause floor space bigger.In addition, the construction of conventional indoor transformer station, high-tension apparatus all indoors, equipment such as 66kV switch, instrument transformer, isolating switch need be arranged in second floor, so the construction area of building is bigger, but also must consider the load-bearing problem in house.Therefore, brought many difficult problems for the construction of transformer station.In order to reduce floor space, also more and more higher to the requirement of transformer, and transformer of the prior art bears the caused destructive ability of system burst short circuit, and also transformer noise is big, and shock resistance and antiseepage leakage of oil effect are all undesirable.
Summary of the invention
The utility model is at above-mentioned problems of the prior art, through a large amount of exploratory development and Test Summaries, transformer in a kind of compound combined electrical equipment is provided, solved the problem that transformer in the prior art bears system burst short circuit caused destructive ability, and, the utility model has improved shock resistance and anti-leakage of oil effect, has reduced noise.
The technical solution of the utility model is as follows:
Comprise sleeve pipe, fuel tank, winding, iron core and device body; Unshakable in one's determination and fuel tank junction is provided with the damping foot pad; The case lid of fuel tank and tank wall add weldering and strengthen iron; Winding adopts inner screen continuous winding, and winding inlet wire mode is the end inlet wire, and coil is a composite conductor; The device body is provided with the thick full circle pressure plate structure of 50～60mm, and outer winding setting of barred window and pressing plate are with the secondary pressing plate of thick semicircle.
The winding of described composite conductor coiling adopts three standard transpositions, and the curved transposition lead of winding " S " is the horizontal drawing transposition.
Adopt oil-gas bushing vertically to go up outlet, is connected with switchgear, connecting portion employing bellows is protected, in fill SF6 gas.
Advantage of the present utility model and beneficial effect are as follows:
1, iron core adopts high magnetic conduction low-loss 120 silicon steel sheets and improves structure, and it is close to reduce magnetic unshakable in one's determination, reduces mangneto and shrinks and noise; Lower yoke member unshakable in one's determination adopts reliable step by step holding, prevent after the transformer long-time running or be subjected to short-circuit impact back core lower yoke member fall.
2, the application of composite conductor can reduce the ratio of line cake width of cloth insulating material in size significantly, reduces the dried amount of contraction of winding, guarantees the degree of packing of winding.The winding of composite conductor coiling adopts three standard transpositions, and this transposition form can make transposed conductor and the leakage field pressure reduction around between unit wires reduce to 1/3 of common single transposition, the inner and insulation safety between the unit when having guaranteed short circuit in winding.The curved transposition lead of winding " S " is the horizontal drawing transposition, avoids the insulation damages of the scissors mouth aggravation of discrepancy in elevation formation up and down to wire turn; " S " the curved line cake cushioning 0.5mm of place protection sheet groove that pastes is strengthened " S " curved transition position turn(s) insulation; And on " S " is curved, add 2 layers of the Dan Nisong paper half laps that the bag thermal endurance class is the F level, because the temperature resistant grade of Dan Nisong wadding is much larger than common A class F insulating material F, thereby can guarantee that " S " curved turn insulation can not be subjected to rupture after the heat ageing under mechanical shock.
3, transformer body is inner adopts multi-faceted fixing, and pressing plate, secondary pressing plate are set, and has solved the hidden danger of end pressing plate undercapacity, and effectively prevents to produce relative displacement when transportation vibration and short circuit in service, has improved shock resistance; Simultaneously, improve the mechanical connection manner between device body and the fuel tank, reduce the transmission from inside to outside of noise unshakable in one's determination.
4, transformer adopting oil-gas bushing vertically goes up outlet, is connected with switchgear, and connecting portion adopts the bellows protection, in fill SF6 gas.
5, by the structures such as thickness of thickening fuel tank tank wall, reduced tank wall resonance.
6, the flange on case lid and the tank wall all adopts blind hole, for rigidity connects, prevents flange screw and sealing surface seepage oil between flange.
