Description

Vertical winding type coil for choke transformer

Technical Field

The utility model relates to the technical field of electrical accessories, in particular to a vertically wound coil for a choke transformer.

Background

The coil of current choke transformer all adopts flat winding formula, and two coils of wire windings set up side by side promptly, cause the gap undersize between layer and the layer like this, directly influence coil air permeability performance, when having heavy current to strike, the too fast and heat of coil temperature rise is difficult to distribute away for the coil is in the high temperature state for a long time, directly influences choke transformer's coil result of use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a vertically wound coil for a choke transformer, which has a simple structure, improves the ventilation property of the coil and reduces the influence of temperature rise on the coil.

In order to achieve the above object, the present invention provides a vertically wound coil for a choke transformer, including a first winding, a second winding, a fixing mechanism and a supporting mechanism;

first wire winding with the second wire winding is flat copper wire winding, first wire winding one deck with be provided with the ventilation clearance between the wire-wound one deck level parallel arrangement of second is just, first wire winding with the second wire winding is fixed through fixed establishment, fixed establishment is provided with a plurality of and includes that the U type presss from both sides and the connecting plate, rectangular shape fixed through hole has been seted up to U type clamp both sides, the both ends of connecting plate set up in the rectangular shape fixed through hole and through the bolt fastening, supporting mechanism inserts and locates in the ventilation clearance.

Preferably, the supporting mechanism comprises at least two supporting insertion plates, a plurality of insertion columns are arranged on one side of each supporting insertion plate, and the insertion columns are arranged in the ventilation gaps.

Preferably, insert the post upside and seted up the forked tail draw-in groove, increase the board bottom and be provided with the forked tail slider, the forked tail slider set up in the forked tail draw-in groove.

Preferably, a plurality of through holes are formed in the outer side of the U-shaped clamp.

Preferably, the tail ends of the first winding and the second winding are provided with wiring through holes.

Therefore, the vertically wound coil for the choke transformer adopting the structure has the following beneficial effects:

(1) the first winding wire and the second winding wire adopt flat winding wires, gaps between winding layers are increased, the overall ventilation of the coil is improved, and a good heat dissipation effect is achieved.

(2) And the first winding wire and the second winding wire are reliably fixed by adopting a fixing mechanism and a supporting mechanism, and the ventilation gap is kept constant.

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description

Examples

Fig. 1 is a schematic structural view of an upright winding type coil for a choke transformer according to the present invention, fig. 2 is a schematic structural view of a fixing mechanism according to the present invention, and fig. 3 is a schematic structural view of a part of a supporting board according to the present invention, where as shown in the figure, an upright winding type coil for a choke transformer includes a first winding 1, a second winding 2, a fixing mechanism, and a supporting mechanism.

First wire winding 1 and second wire winding 2 are flat copper wire winding, and the one deck of first wire winding 1 and the one deck horizontal parallel arrangement of second wire winding 2 are provided with ventilation gap 7 between and, improve the air permeability to improve the thermal diffusivity. First wire winding 1 and second wire winding 2 are fixed through fixed establishment, and fixed establishment is provided with a plurality of and presss from both sides 4 and connecting plate 6 including the U type, and rectangular shape fixing hole 42 has been seted up to 4 both sides of U type clamp, and the both ends of connecting plate 6 set up in rectangular shape fixing hole 42 and pass through the bolt fastening, and a plurality of through-holes 41 have been seted up in the U type clamp 4 outside. The tail ends of the first winding wire 1 and the second winding wire 2 are provided with wiring through holes 3, so that the process of welding wiring rings is reduced, and the reliability is improved.

The supporting mechanism is inserted in the ventilation gap 7 and comprises at least two supporting inserts 5, a plurality of inserting columns 51 are arranged on one side of each supporting insert plate 5, and the inserting columns 51 are arranged in the ventilation gap 7. The inserting column 51 upside has been seted up the forked tail draw-in groove, increases the board 52 bottom and is provided with the forked tail slider, and the forked tail slider sets up in the forked tail draw-in groove, can increase board 52 according to the size setting of actual ventilation clearance 7.
