Abstract
The invention discloses an amorphous alloy 35kV oil immersed type wind power transformer, which mainly comprises a transformer oil tank, a transformer body arranged in the oil tank, and a tank cover arranged on the top of the oil tank. Transformer oil is filled in the transformer oil tank; the transformer body comprises an iron core wound by an amorphous alloy strip and windings; and the windings comprises a high-voltage winding with voltage of 35kV or 38.5kV and a low-voltage winding with the voltage of 0.69kV. Compared with the common silicon steel sheet iron-core transformer with the same voltage class and capacity, the amorphous alloy 35kV oil immersed type wind power transformer has the advantages that: iron core adopts the amorphous alloy strip, so the no-load loss of the amorphous alloy 35kV oil immersed type wind power transformer is reduced by about 60 percent to play a good role in energy conservation and environmental protection; and the whole shell has a full-sealed structure, so the transformer can effectively isolate the mutual influence between the transformer oil and atmosphere, and reduces the adverse factors of influencing the service life of the transformer and air pollution.
Description
Technical field
The present invention relates to a kind of power transformer, relate in particular to a kind of non-crystaline amorphous metal 35kV oil immersed type wind power transformer.
Background technology
The oil-filled transformer that uses in the wind power generation of 35kV grade all is to be oil-filled transformer unshakable in one's determination with the silicon steel sheet at present, and the no-load loss of the type transformer is very huge, the waste that easily produces air pollution and cause the energy.
Simultaneously, the wind-power electricity generation project of present domestic 35kV grade is in continuous expansion, but the domestic and international amorphous alloy oil immersion type wind power transformer that does not still have the 35kV grade, so the market demand of such transformer rises day by day.
Summary of the invention
Purpose of the present invention provides a kind of non-crystaline amorphous metal 35kV oil immersed type wind power transformer exactly in order to address the above problem, no-load loss is 40% of silicon steel sheet.
The object of the present invention is achieved like this:
The invention discloses a kind of non-crystaline amorphous metal 35kV oil immersed type wind power transformer, it comprises oil tank of transformer, place the transformer body of fuel tank, place the case lid and the high-voltage tap changer that places fuel tank one side at fuel tank top, be filled with transformer oil in the described oil tank of transformer, it comprises that also several that place the fuel tank opposite side are used for the cable connect-disconnect plug of high-voltage terminal, described transformer body comprises the iron core and the winding of being reeled and being formed by amorphous alloy strips, described transformer core is four frame pentastyle structures, described winding comprises high pressure winding and low pressure winding, is lined with crash roll under the described transformer body.
Seal welding is adopted in the junction of described fuel tank and described case lid.
Described transformer oil upper box part leaves the dry air layer.
Described transformer oil is common transformer oil or high ignition point oil.
The amorphous alloy oil immersion type wind power transformer of 35kV grade of the present invention, filled up domestic and international blank, because the amorphous alloy strips that adopts unshakable in one's determination, its no-load loss is than the silicon steel plate core transformer low about 60% of identical electric pressure and capacity, played the good energy-conservation environment protecting, and,, the unfavorable factor that influences transformer useful life and the pollution of atmosphere have been reduced so can effectively completely cut off transformer oil influencing each other between atmosphere because shell integral body of the present invention is all-sealed structure.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
The present invention is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, Fig. 2, non-crystaline amorphous metal 35kV oil immersed type wind power transformer of the present invention mainly comprises oil tank of transformer 3, places transformer body 1 and the case lid 4 that places fuel tank 3 tops in the fuel tank 3.Transformer body 1 is made up of amorphous alloy core 11 and winding 12, amorphous alloy core 11 is arranged in four frame pentastyles, winding 12 connection sets are Dyn11, form by high pressure winding 121 and low pressure winding 122, high pressure winding 121 electric pressures are 35kV or 38.5kV, and low pressure winding 122 voltages are 0.69kV.
Device body 1 is installed in the fuel tank 3, and the bottom is lined with crash roll 5 to reduce the noise of product.Be filled with transformer oil 2 in the fuel tank 3, it plays the effect of insulation and heat radiation, and transformer oil 2 can be common transformer oil or high ignition point oil.Fuel tank 3 becomes all-sealed structure with case lid 4 welding with one, and isolated transformer oil 2 contacts with outside atmosphere, has prolonged the useful life of transformer oil 2 greatly.A certain amount of dry air layer is left on fuel tank 3 tops, regulates expansion and the contraction that transformer oil causes owing to variations in temperature by the expansion and the compression of air.
High-voltage tap changer 6 is installed in the side of fuel tank 3, has reduced the height of shunting switch 6 like this, and is easy to operate.High-voltage terminal adopts the cable connect-disconnect plug 7 of 40.5kV, place on the side adjacent on the fuel tank 3 with high-voltage tap changer 6 place faces, its interface meets the interface standard of Europe superscript EN 50180 and EN 50181, this structure substitutes the overall dimension that traditional bushing has not only dwindled transformer greatly, also improved fail safe, making exposed parts is zero potential, and it is installed in wind-powered electricity generation tower or the preassembled transformer station become possibility.
In sum, the present invention is to be unshakable in one's determination with the non-crystaline amorphous metal, and the transformer body of the amorphous alloy core of particular design be impregnated in the transformer insulation oil, can reduce the no-load loss of transformer significantly, has played the good result of energy-saving and environmental protection.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
