Description
Technical field
The present invention relates to a kind of power transformer, relate in particular to a kind of environmental and durable type amorphous alloy transformer.
Background technology
Distribution transformer is a pith in low-voltage distribution system, and its structure and performance not only concern user's use, but also directly affects efficient and the performance of electrical network.For a long time, the domestic distribution transformer that uses all is the structure of silicon steel sheet stack iron core overcoat coil windings, this tradition distribution transformer exposure place line loss large, the drawback such as no-load loss is large, and no-load current is large.
The utility model content
Order of the present utility model is to overcome defects, provides a kind of simple and reasonable, and production and processing is convenient, the environmental and durable type amorphous alloy transformer of low no-load loss.
The utility model purpose realizes with the following methods: a kind of environmental and durable type amorphous alloy transformer, it comprises oil tank of transformer, be placed in the transformer body of fuel tank, be placed in top of oil-tank case lid, be placed in several low-tension bushings on case lid, the oil level indicator that is placed in fuel tank one side, high-voltage tap changer and thermometer, be filled with transformer oil in described oil tank of transformer, it is characterized in that, it also comprises several cable plug heads for high-voltage terminal that are placed on case lid, and described transformer body comprises iron core and the winding of being reeled and being formed by amorphous alloy strips.
Described transformer oil is common transformer oil or high burning-point insulating oil.
Welded seal 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 winding comprises high pressure winding and low pressure winding.
Described transformer core is four frame pentastyle structures.
Be lined with crash roll under described transformer body.
The beneficial effects of the utility model are: 1) simple in structure, production cost is low, improves the market competitiveness.2) the amorphous alloy oil immersion type wind power transformer of 20KV grade of the present invention, filled up domestic and international blank, because iron core adopts amorphous alloy strips, its no-load loss is than low 60% left and right of silicon steel plate core transformer of identical electric pressure and capacity, played good effects of energy conservation and environmental protection, and because shell integral body of the present invention is all-sealed structure, therefore can effectively completely cut off transformer oil influencing each other between atmosphere, the unfavorable factor that affects transformer useful life and the pollution of atmosphere have been reduced.
Description of drawings
Figure l is the utility model structural representation;
Fig. 2 is the left view of figure l in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made concrete further instruction.Referring to figure l, Fig. 2, a kind of environmental and durable type amorphous alloy transformer mainly comprises oil tank of transformer 3, is placed in transformer body l and the case lid 4 that is placed in fuel tank 3 tops in fuel tank 3.Transformer body l is comprised of amorphous alloy core 11 and winding l2, amorphous alloy core 11 is arranged in four frame pentastyles, winding 12 connection sets are Dyn11, by the high pressure winding: 121 and the low pressure winding: 122 form, the high pressure winding: 121 electric pressures are 20KV, the low pressure winding: 122 voltages are 0.69KV.
Transformer body l is arranged in 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 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 greatly extended the useful life of transformer oil 2.A certain amount of dry air layer is left on fuel tank 3 tops, regulates by expansion and the compression of air expansion and the contraction that transformer oil causes due to variations in temperature.Oil level indicator 6, high-voltage tap changer 7 and thermometer 8 are installed respectively in the side of fuel tank 3, and the encapsulant through high-quality between each parts and fuel tank seals.
High-voltage terminal adopts the cable of 3 24KV to disclose to pull out 9, be placed on case lid, its interface meets the interface standard of Europe superscript EN50l80 and EN50l8, this structure substitutes traditional bushing and has not only greatly dwindled the overall dimension of transformer, also improved fail safe, making exposed parts is zero potential, and it is installed in wind tower or preassembled transformer station become possibility.Low-pressure line-outgoing adopts 4 low-tension bushings 10, also is placed on case lid.
Fuel tank 3 and case lid 4 outsides scribble corrosion-resistant, improved abrasion resistant coating in addition, with adapt to coastal and the inland dust storm large etc. than adverse circumstances.
In sum, the present invention is take non-crystaline amorphous metal as unshakable in one's determination, and the transformer body of the amorphous alloy core of particular design be impregnated in transformer insulation oil, and no-load loss that can the decrease transformer has played the good result of energy-saving and environmental protection.
Obviously, above-described embodiment is only for example clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And the apparent variation of being extended out thus or change still are among the protection range of claims of the invention.
