Abstract
The utility model relates to the technical field of transformers, in particular to a dry type transformer tapping nut structure which comprises a brass hex nut and a tapping lead. A linking groove is formed in the brass hex nut, and a corresponding end of the tapping lead is embedded in the linking groove and fixedly connected with the brass hex nut in a welded mode. The linking groove is formed at the end of the brass hex nut through machining operation, and the transformer tapping lead can be conveniently embedded into the linking groove and then welded with the brass hex nut. Therefore, the dry type transformer tapping nut structure has the advantages of improving welding reliability, ensuring welding quality, improving welding efficiency and reducing welding wire cost. In terms of aluminum coils, a procedure of additionally welding copper wires on the tapping lead can be omitted, copper wires are saved, and the product cost is reduced.
Description
Technical field
The utility model relates to transformer technology field, particularly resin-insulated dry power transformer.
Background technology
Advantage such as that resin-insulated dry power transformer has is fire-retardant, pollution-free, explosion-proof, moistureproof, capability of overload is strong, no-load loss is low.Have simultaneously that partial discharge quantity is low, noise is little, product reliability is high, the characteristics of long service life.Be specially adapted to important places such as skyscraper, commercial center, theater, hospital, hotel, tunnel, subway, underground power station, laboratory, station, harbour, airport, assembly transformer substation.No matter be the plane iron core or the dry-type transformer of three dimensional wound core structure, in traditional design, according to customer requirements, existing copper material coil also has the aluminium coil, and tap is lifted one's head all to be needed to weld with brass nut, still directly weld with the brass nut end plane at present for high pressure head lead-in wire, welding wire after the heat fusing runs off easily, causes cost to increase, and welding quality is difficult to guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of transformer tap nut structure, guarantees the winding wiring structure of welding quality and raising electrical safety performance, reduction transformer cost.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of dry-type transformer tap nut structure comprises hexagonal brass nut and tap lead, offers connecting groove on the hexagonal brass nut, and the respective end of tap lead is embedded in the connecting groove and by welding and hexagonal brass nut and is fixed together.
Such scheme further is: described connecting groove is opened on the termination of hexagonal brass nut, and for open, the respective end of the shape of connecting groove, size and tap lead is complementary, and the bottom surface of tap lead and connecting groove is smooth.
Such scheme further is: described tap lead and hexagonal brass nut are vertical relation.
The utility model has designed a connecting groove in hexagonal brass nut end by machining, is convenient to the transformer tap lead and embeds behind the connecting groove welding with the hexagonal brass nut; Thus obtained beneficial effect is: improve soldering reliability, guarantee welding quality, improve welding efficiency, reduce the welding wire cost; Can save tap lead for the aluminium coil and add the bit copper line, save copper cash, reduce product cost.
Description of drawings
Accompanying drawing 1 is a preferred embodiment structural representation of the present utility model;
Accompanying drawing 2 is STRUCTURE DECOMPOSITION schematic diagrames of Fig. 1 embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1,2, the relevant a kind of dry-type transformer tap nut structure of the utility model, it comprises hexagonal brass nut 1 and tap lead 2, on hexagonal brass nut 1, offer connecting groove 11, and tap lead 2 one end connecting coils, the other end of tap lead 2 then is embedded in the connecting groove 11 and by welding and hexagonal brass nut 1 and is fixed together.
Shown in Figure 2, described connecting groove 11 is opened on the termination of hexagonal brass nut 1, and for open, the respective end of the shape of connecting groove 11, size and tap lead 2 is complementary, and tap lead 2 is smooth with the bottom surface of connecting groove 11.When welding was connected, heating hexagonal brass nut 1 heated tap lead 2 more earlier, and tap lead 2 fuses into welding wire in the groove after rabbeting with connecting groove 11 again, and raise a little at the notch position of connecting groove 11 during welding, in case fuse flows out.Simple to operate, save welding wire, firm welding, good conductivity; More can save the soldering copper line procedures to the aluminium coil, reduce cost.After the connection, described tap lead 2 is vertical relation with hexagonal brass nut 1, satisfies the wiring requirement.
The utility model has designed a connecting groove in hexagonal brass nut end by machining, is convenient to the transformer tap lead and embeds behind the connecting groove welding with the hexagonal brass nut; Thus obtained beneficial effect is: improve soldering reliability, guarantee welding quality, improve welding efficiency, reduce the welding wire cost; Can save tap lead for the aluminium coil and add the bit copper line, save copper cash, reduce product cost.
Certainly; abovely the utility model is described in detail in conjunction with execution mode; only be explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the present utility model.
