Abstract
The utility model discloses a novel oily formula metallic glass transformer, including box and ware body, the box includes case lid and oil tank, be equipped with transformer oil in the box, ware body is established in the box, ware body including uses metallic glass as the iron core of raw materials, coil, go up folder and time folder, the coil is formed by the wire coiling, the outer cladding of wire has insulating baseband, the whole perhaps parts of coil insulating baseband on the whole are equipped with preimpregnation solidification insulated paint layer, after the coil drying, solidify into a whole, and reinforcing transformer short -circuit resistant ability does not make extra atress unshakable in one's determination, and the simplification production technology reduces manufacturing cost.
Description
Technical field
This utility model relates to a kind of novel oil-immersed type non-crystal alloy transformer.
Background technology
Oil-immersed type non-crystal alloy transformer is as a kind of energy-economic transformer, it is widely used in every field, but the anti-short circuit capability of tradition oil-immersed type non-crystal alloy transformer is poor, State Grid Corporation of China increasingly paid attention to the anti-short circuit capability of transformator in recent years, continue to increase inspecting force, too increase the bid ratio of oil-immersed type non-crystal alloy transformer simultaneously.Therefore strengthen transformator anti-short circuit capability to be particularly important.Coil, in order to strengthen the anti-short circuit capability of oil-immersed type non-crystal alloy transformer, can be carried out overall dipping lacquer and process, be dried curing process afterwards so that coil is solidified into one by the most a lot of producers.Or when transformer body assembles, between iron core and interior loop, place hard stay, and preventing from deforming during coil stress, but so can make amorphous alloy core stress, increase transformer noise, product manufacture is complicated, and manufacturing cost is higher.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel oil-immersed type non-crystal alloy transformer, strengthens the anti-short circuit capability of oil-immersed type non-crystal alloy transformer, advantageously reduces the manufacturing process of oil-immersed type non-crystal alloy transformer simultaneously.
This utility model the technical scheme is that for solving its technical problem
A kind of novel oil-immersed type non-crystal alloy transformer, including casing and device body body, described casing includes case lid and fuel tank, it is provided with transformer oil in described casing, described device body body is located in casing, device body body includes the ferrum heart with non-crystaline amorphous metal as raw material, coil, upper clamping piece and lower clamping piece, described iron core includes core limb, upper yoke and lower yoke, described coil encircling is on core limb, described upper clamping piece is corresponding with described lower clamping piece to be arranged on described upper yoke and described lower yoke, by drawing screw rod to connect between upper clamping piece and lower clamping piece, described casing is provided with high-low pressure terminal and off circuit tap changer, described coil is formed by wire coiling, described wire is coated with insulation base band, described coil insulation base band on the whole is all or local is provided with preimpregnation curable insulating paint layer.
Further, the upper and lower end of described coil and the insulation base band at middle part have preimpregnation curable insulating paint layer.
Further, described coil has minor insulation base band to use multilamellar preimpregnation curable insulating paint layer to carry out adding strong cured.
The beneficial effects of the utility model are: the novel oil-immersed type non-crystal alloy transformer of one of the present utility model, by being coated with the wire coiling of insulation base band, and the insulation base band that coil is on the whole is all or local is soaked with the curable insulating paint layer that can hold with oil phase in advance, coil is dried, it is solidified into an entirety, strengthens transformator anti-short circuit capability, do not make extra stress unshakable in one's determination, simplify production technology, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the loop construction schematic diagram of embodiment one of the present utility model；
Fig. 2 is the coil result schematic diagram of embodiment two of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
The novel oil-immersed type non-crystal alloy transformer of one of the present utility model, including casing and device body body, described casing includes case lid and fuel tank, it is provided with transformer oil in described casing, described device body body is located in casing, device body body includes the ferrum heart with non-crystaline amorphous metal as raw material, coil, upper clamping piece and lower clamping piece, described iron core includes core limb, upper yoke and lower yoke, described coil encircling is on core limb, described upper clamping piece is corresponding with described lower clamping piece to be arranged on described upper yoke and described lower yoke, by drawing screw rod to connect between upper clamping piece and lower clamping piece, described casing is provided with high-low pressure terminal and off circuit tap changer, described coil is formed by wire coiling, described wire is coated with insulation base band.
Needing during oil-immersed type non-crystal alloy transformer coil winding to use layer insulation, hold insulation, therefore coil can use integrally curing or local solidification, the insulation base band presoaking solidified paint of local strengthening solidification according to design needs.
As it is shown in figure 1, entirety can be used during coil winding to be soaked with the insulation base band of curing materials, coil is dried, and whole coil is solidified into an entirety.
As in figure 2 it is shown, the only upper and lower end of coil and the insulation base band at middle part can be used during coil winding to have preimpregnation curable insulating paint layer, at the position not having curable insulating paint layer, insulation base band only plays insulating effect.
During coil winding, according to design conditions, coil can be taked to have in minor insulation base band has multilamellar to presoak curable insulating paint layer, to reach to add strong cured purpose so that coil is dried, and intensity is higher.
The above, preferred embodiment the most of the present utility model, this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
