Abstract

The utility model discloses a half rewinding type low-voltage coil which comprises an insulating cylinder and a coil wound outside the insulating cylinder, wherein the coil comprises a first coil and a second coil which are parallelly arranged side by side; and the second coil winds a circle along the insulating cylinder, the first coil winds two circles along the insulating cylinder, after downward transition, the first coil winds a circle along the insulating cylinder, and the winding is performed sequentially and circularly. According to the half rewinding type low-voltage coil, the two coils adopt special half rewinding winding, so that transposition between the coils is facilitated, the position is adjustable, the sizes of the coils are reduced greatly, and the cost is reduced.

Description

Half backrush type low-voltage coil
Technical field
The utility model relates to field transformer, particularly relates to a kind of for half backrush type low-voltage coil in the transformer.
Background technology
Existing low voltage winding in transformers is general to adopt one or two coils around the direct helically coiling from top to bottom of insulating cylinder, and such low-voltage coil volume is bigger, can't replace, and the position can't be adjusted, and wasted material widely, and cost is higher.
The utility model content
It is ingenious reasonable, solid and reliable that the technical problem that the utility model mainly solves provides a kind of design, the half backrush type low-voltage coil that can reduce volume, reduces cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of half backrush type low-voltage coil is provided, comprise insulating cylinder and be wound on the outer coil of insulating cylinder, described coil comprises first coil and second coil, described first coil is set up in parallel with second coil is parallel, second coil is along insulating cylinder coiling one circle, first coil is along insulating cylinder coiling two circles, after the transition downwards, second coil is along insulating cylinder coiling two circles, first coil is along insulating cylinder coiling one circle, and coiling successively circulates.
In preferred embodiment of the utility model, each circle coil bottom is provided with some cushion blocks, and described cushion block circumferentially evenly is arranged on coil bottom along insulating cylinder.
In preferred embodiment of the utility model, described cushion block is the ox horn shape, and the cushion block inboard has groove.
In preferred embodiment of the utility model, be provided with oil duct between each circle coil.
In preferred embodiment of the utility model, described coil head end and the cooperation of the terminal outside are placed with the dihedral ring.
In preferred embodiment of the utility model, described coil head end and terminal root are surrounded by insulating barrier.
In preferred embodiment of the utility model, described coil is outer to be fixed by stay.
The beneficial effects of the utility model are: the utility model half backrush type low-voltage coil adopts special half backrush around volume by two coils, has made things convenient for the transposition between the coil, and the position is adjustable, greatly reduces the volume of coil, has reduced cost.
Description of drawings
Fig. 1 is the perspective view of the utility model half backrush type low-voltage coil one preferred embodiment;
Fig. 2 is the structural representation of the coil winding of the utility model half backrush type low-voltage coil;
Fig. 3 is the structural representation of the cushion block of the utility model half backrush type low-voltage coil;
The mark of each parts is as follows in the accompanying drawing: 1, first coil, 2, second coil, 3, insulating cylinder, 4, cushion block, 5, stay, 6, insulating barrier, 7, groove, 8, interior transposition center.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of half backrush type low-voltage coil, comprise insulating cylinder 3 and be wound on insulating cylinder 3 coil outward, described coil comprises first coil 1 and second coil 2, described first coil 1 and second coil, 2 parallel being set up in parallel, second coil 2 are along insulating cylinder 3 coilings one circle, and first coil 1 is along insulating cylinder 3 coilings two circles, after the transition downwards, second coil 2 is along insulating cylinder 3 coilings two circles, and first coil 1 is along insulating cylinder 3 coilings one circle, and coiling successively circulates.
As shown in Figure 3, each circle coil bottom is provided with some cushion blocks 4, and described cushion block 4 circumferentially evenly is arranged on coil bottom along insulating cylinder 3.Described cushion block 4 is the ox horn shape, and cushion block 4 inboards have groove 7.When first coil 1 or 2 transpositions of second coil, cushion block 4 can play the effect of transition at interior transposition center 8.Groove 7 and the insulating cylinder 3 of cushion block 4 inboards are complementary, and sound construction is reliable.Cushion block 4 adopts hardboard to make, and easy to process, cost is lower.
Be provided with oil duct between each circle coil, the oil duct place is placed with oil baffle, has improved the heat dispersion of coil greatly, and is safe and reliable.
Described coil head end and the cooperation of the terminal outside are placed with the dihedral ring, make coil more firm, are difficult for loose.
Described coil head end and terminal root are surrounded by insulating barrier 6, and insulating barrier 6 thickness are 2mm, improve insulation effect.
Described coil is fixing by stay 5 outward, fixation.
Compared with prior art, the utility model half backrush type low-voltage coil adopts special half backrush around volume by two coils, has made things convenient for the transposition between the coil, and the position is adjustable, greatly reduces the volume of coil, has reduced cost.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
