Abstract
The utility model discloses a special-purpose coil for a high boron pipe electric melting furnace transformer. The special-purpose coil comprises a magnetic core and a plurality of wires which are winded on the magnetic core, wherein the wires are naked wires, a plurality of winded naked wires are spirally distributed on the magnetic core along the axial direction of the wires. A plurality of winded naked wires are not insulated, and are conducted, magnetic leakage induced potentials are the same, no ring current exists between the wires, the wires do not need transposing during the process of winding, thereby saving the effective space of the coil, and improving the filling coefficient of the coil. The coil for the transformer can be suitable for the occasions with big electric current, extremely more winding numbers and extremely less number of turns.
Description
Technical field
The utility model relates to a kind of transformer coil, is specifically related to the special-purpose coil of a kind of high boron pipe electric smelter transformer.
Background technology
In the prior art, as shown in Figure 1, transformer coil on the high boron pipe electric smelter, repeatedly turned on magnetic core by many eradications edge lead 1 ', in winding process, lead will replace, make mutually repeatedly around the symmetrical fully exchange of every lead of parallel connection, conductor length equates that shared leakage field position is identical, does not have circulating current between the lead of many parallel connections.Adopt the insulated conductor coiling, insulation can take the useful space of coil.Each transposition can increase the height of a lead, make that the activity coefficient of coil is little, and transposition has increased technology difficulty, reduced operating efficiency, repeatedly many around lead, and the number of turn replace especially after a little while and is difficult to realization, moreover, in transposition, easily short circuit and burn whole winding between adjacent wires.
Summary of the invention
The purpose of this utility model is to provide a kind of and adopts many plain conductors repeatedly around the transformer coil that need not to replace.
In order to reach above purpose, the technical solution adopted in the utility model is: the special-purpose coil of a kind of high boron pipe electric smelter transformer, comprise magnetic core, the multiple conducting wires on the described magnetic core repeatedly, described lead is a plain conductor, many repeatedly around plain conductor in described magnetic core upper edge its axially in the shape of a spiral shape distribute.
Described coil comprises elementary winding, secondary winding, and described elementary winding, described secondary winding divide about layer to be provided with on described magnetic core, and the identical central axis is provided with.
Because the utility model has adopted above technical scheme, its advantage is: many repeatedly around plain conductor between not insulation, it between lead conducting, the leakage field induced potential equates, do not have circulation between lead, lead need not to replace in winding process, thereby saves the useful space of coil, improve the activity coefficient of coil, transformer coil of the present utility model is applicable to big electric current,, occasion that the number of turn especially few many especially around radical repeatedly.
Description of drawings
Accompanying drawing 2 is a schematic diagram of the present utility model.
Embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 2, the special-purpose coil of a kind of high boron pipe electric smelter transformer comprises magnetic core, many plain conductors 1 on the magnetic core repeatedly, many repeatedly around plain conductor 1 in the magnetic core upper edge its axially in the shape of a spiral shape distribute.The special-purpose coil of this transformer is a concentric coil, and the concentric meaning refers to: the elementary winding on the coil, secondary winding divide about layer to be provided with on magnetic core, and concentricity axis setting.Adopt plain conductor repeatedly around, many repeatedly around lead between not insulation, it between lead conducting, the leakage field induced potential equates, do not have circulation between lead, lead need not to replace in winding process, saves the useful space of coil, improve the activity coefficient of coil, transformer coil of the present utility model is applicable to big electric current,, occasion that the number of turn especially few many especially around radical repeatedly.
