Abstract
The invention discloses an amorphous alloy 20kV 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 the voltage of 20kV 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 20kV oil immersed type wind power transformer has the advantages that: the iron core adopts the amorphous alloy strip, so the no-load loss of the amorphous alloy 20kV 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 20kV oil immersed type wind power transformer.
Background technology
The oil-filled transformer that uses in the wind power generation of 20kV 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.
Summary of the invention
Purpose of the present invention provides a kind of non-crystaline amorphous metal 20kV oil immersed type wind power transformer exactly in order to address the above problem, no-load loss is 60% of silicon steel sheet.
The object of the present invention is achieved like this:
The invention discloses a kind of non-crystaline amorphous metal 20kV oil immersed type wind power transformer, it comprises oil tank of transformer, place the transformer body of fuel tank, place the case lid at fuel tank top, place several low-tension bushings on the case lid to be used for the cable connect-disconnect plug of high-voltage terminal and the oil level indicator that places fuel tank one side with several, high-voltage tap changer and thermometer, be filled with transformer oil in the described oil tank of transformer, 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 20kV 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 20kV 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, and winding 12 connection sets are Dyn11, is made up of high pressure winding 121 and low pressure winding 122, high pressure winding 121 electric pressures are 20kV, and low pressure winding 122 voltages are 0.69kV.
High-voltage terminal adopts the cable connect-disconnect plug 9 of 3 24kV, place on the case lid, its interface meets the interface standard of Europe superscript EN50180 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.4 low-tension bushings 10 are adopted in the low pressure outlet, also place on the case lid.
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.
