Description
Technical field
The present invention relates to a kind of high-voltage electrical equipment, relate in particular to a kind of transformer group 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.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, through a large amount of exploratory development and Test Summaries, a kind of transformer group compound combined electrical equipment that transformer is combined with HGIS is provided, solved the problem that floor space is big in the prior art, cost is high, and the present invention has improved intelligent level.
Technical scheme of the present invention is as follows:
Comprise transformer and high voltage switchgear, be set to three-dimensional duplex, transformer adopting vertically goes up the outlet pattern, and the quiet side sleeve pipe of high voltage switchgear is set to vertical direction, and transformer directly links to each other with the circuit breaker fracture of high voltage switchgear by oil-gas bushing; The quiet side ferrule boot of high voltage switchgear is equipped with temperature sensor, the startup of temperature sensor control transformer blower fan and stopping.
Described high voltage switchgear links to each other with fixed support.
The tri-station isolating switch of described high voltage switchgear is sealed in the air chamber, on the air chamber side seal flange visual camera lens can be installed.
Described oil-gas bushing has adopted bellows to be flexible coupling.
The coil of the current transformer of described high voltage switchgear is integrated poured on a tube, and the outer wall of a tube is provided with the epoxy resin screen; The wiring outlet is reserved in the below of current transformer.
The iron core of described transformer adopts high magnetic conduction low-loss 120 silicon steel sheets; Unshakable in one's determination and fuel tank junction is provided with the damping foot pad; The high pressure winding adopts inner screen continuous winding, and winding inlet wire mode is the end inlet wire, and coil is a composite conductor, and the winding of composite conductor coiling adopts three standard transpositions; Device adopts the thick full circle pressure plate structure of 50～60mm on one's body down, and outer winding setting of barred window and pressing plate are with the secondary pressing plate of thick semicircle.
The oiling of described transformer adopting vacuum.
Advantage of the present invention and beneficial effect are as follows:
1, the present invention directly connects by oil-gas bushing, and require HGIS to be arranged in the top of transformer, the outlet method of transformer high-voltage routine and the inlet wire mode of HGIS have been changed fully, the equipment of two kinds of difference in functionalitys is become one, make that the functions of the equipments after the combination are complete, structure is compact more; Make transforming plant primary equipment integrated, outdoor layout cancelled power distribution station every, floor space has reduced over half, the expropriation of land investment of saving project greatly.Simultaneously, because the minimizing of the quantity of transforming plant primary equipment makes that installing, debug equal time shortens greatly.
2, by the present invention, the power distribution equipment floor has been cancelled in the construction of indoor transformer station, and it is just enough to adopt one deck to arrange, has significantly reduced construction area, and need not consider the load-bearing requirement of primary equipment substantially, reduces building cost more than 50%.
3, because the height of an equipment is integrated, require primary equipment must accomplish non-maintaining or few service equipment, reduced operation maintenance amount and maintenance cost.
4, can realize intellectualized operation, digitlization terminal, GIS implements on-line monitoring.The intelligent level of transformer station is improved greatly.
5, by HGIS is connected with fixed support, HGIS is when carrying out breaking-closing operating, of the vibrations of divide-shut brake moment kinetic energy have been eliminated to transformer, and the mode that oil-the gas bushing position has adopted bellows to be flexible coupling, not only cushioned of the influence of operation kinetic energy, and guaranteed that the sealing effectiveness of connecting portion is unaffected transformer.
6, the ferrule boot at HGIS has installed temperature sensor additional, and transformer blower fan has reduced the transformer upper temp at the side of fin cross blowing, can improve the operating ambient temperature of the top HGIS of transformer effectively.
7, three-station can be installed visual camera lens, and vision signal teletransmission transformer station or centralized control center after operations staff's operation, can accurately monitor the position of tri-station isolating switch.
8, transformer can bear the caused destructiveness of sudden short circuit of system fully by said structure is set; Reduce noise of transformer, strengthened the shock resistance of transformer, and effectively prevented transformer seepage oil.
