Description
Technical field
The utility model relates to a kind of combined transformer, relates in particular to a kind of combined transformer that uses in wind power generation.
Background technology
35kV used for wind power generation combined transformer is to be used in the wind-driven generator outlet, and voltage is boosted to the electric equipment that is connected to the grid behind the 35kV by 0.69kV.Mainly there is following technical problem in present domestic existing product: high pressure primary element and transformer are in same fuel tank, and the free carbon that high voltage load switch operation and fuse blows produce pollutes transformer body easily; The high pressure entrance bushing is installed and to be taken than the large tank space, and it is long to be electrically connected route, causes non-ferrous metal to waste, and also is unfavorable for the wiring of high-tension cable.
Summary of the invention
For solving the problems referred to above that exist in the existing used for wind power generation combined transformer, the utility model provides a kind of branch box used for wind power generation combined transformer, and its technical scheme of taking is:
This transformer comprises casing and is located at the high-tension cable chamber that is the isosceles triangle layout in the casing, the operation with high pressure chamber, low voltage operated chamber, pressure-oil tank and oil tank of transformer, its medium and high voltage cable chamber is positioned at the left side, operation with high pressure chamber and low voltage operated chamber are positioned at the place ahead, right side, obstructed pressure-oil tank and the oil tank of transformer of oil circuit is positioned at the rear, right side mutually, the oil tank of transformer rear portion is provided with radiator, be provided with transformer body in the oil tank of transformer, be provided with high-voltage switch gear and high-tension fuse in the pressure-oil tank, the low voltage operated indoor low-voltage cabinet that is provided with, high-tension cable is indoor to be provided with by the interconnective high pressure sensor of bus, lightning arrester and bushing, wherein lightning arrester and bushing tilt to be fixed on the casing, low-voltage cabinet connects transformer body by low-tension bushing, transformer body connects high-tension fuse by wall bushing, and high-voltage switch gear connects outside line by bushing.
Radiator adopts elastic heat dissipating device or gilled radiator.
High-tension cable chamber, operation with high pressure chamber, low voltage operated chamber, pressure-oil tank, oil tank of transformer are isosceles triangle to be arranged, the distance between the high and low pressure chamber of having furthered makes operation easier.Heat radiation adopts elastic heat dissipating device or gilled radiator to place the fuel tank rear portion, helps transformer and better dispels the heat.
Adopt on the Oiltank structure and divide box design, be divided into two of pressure-oil tank and oil tank of transformer, adopt wall bushing to realize that fuse is to being electrically connected between the transformer body between two fuel tanks, oil circuit is obstructed between two fuel tanks, solved of the influence of the free carbon of high voltage load switch operation and high-tension fuse fusing generation, thereby guaranteed that oil tank of transformer is not contaminated transformer.
Bushing and high-voltage arrester all tilt to be installed on the casing, can effectively save space, high-tension cable chamber, dwindle the product floor space, and it is short to be electrically connected route, effectively saved the use amount of copper material, the external cable position height reaches more than the 900mm, can realize more turnover line loop, and is convenient and practical.
Therefore it is attractive in appearance to the utlity model has monnolithic case, and production cost is low, and complete property is strong, structural strength height, characteristics such as excellent radiation performance.
