Abstract
The utility model relates to a segmental transformer high voltage coil skeleton. The main body of the skeleton is provided with a plurality of winding wire slots divided by segmental dividing boards and transitional jumper wire slots across the winding wire slots. The jumper wire slot is close to the corner of the main body of the skeleton, the cross section is V-shaped, the first slot surface is the plane of extension of the bottom plane of the winding wire slot, and the second slot surface is distributed to satisfy the requirement of the jumper wire according to the V-shaped opening width of the jumper wire slot. The utility model has the advantage of simple structure. At the time of winding wire, a transitional conducting wire can be in the direct transition from the upper part of the front winding wire slot to the bottom of the next winding wire slot along the tangential direction of the circular arc of the skeleton, the position of the transitional jumper wire slot and the walking direction of the transitional conducting wire are reasonable, and the insulating performance of a transformer coil is good.
Description
The utility model belongs to the transformer technology scope, particularly relates to a kind of high voltage ring skeleton of segmented transformer.
Transformer, particularly high power be than transformer, for example gas tube sign transformer, the voltage of its high-tension coil is high especially, normal existence insulation and heat radiation are more difficult, and the material consumption problem of higher, and prior art adopts the segmented high voltage ring skeleton to solve this problem preferably.But the segmented high voltage ring skeleton of prior art, its transition wire jumper groove is generally all opened the centre on the skeleton plane, it is the straight line position of skeleton, the coil rack of this wire jumper groove, during coiling, the transition lead can not carry out the transition to the bottom of back one winding slot from the top of last winding slot, causes the transition lead minimum with the wire pitch on last winding slot top or contact, to cause the dielectric strength reduction of coil.
Task of the present utility model provides a kind of improved segmented transformer high voltage ring skeleton, to overcome the existing above-mentioned drawback of prior art skeleton.
Task of the present utility model is to improve realization on the basis of existing technology, it comprises the skeleton body, some winding slots and the transition wire jumper groove that traverses winding slot, its main points are that this wire jumper groove is near skeleton body bight, the cross section becomes " V " font, first groove face is roughly the extended surface of winding slot groove bottom, and second groove face satisfies the wire jumper requirement by wire jumper groove " V " shape A/F and lay.
Fig. 1 is a front view of the present utility model
Fig. 2 is an end view of the present utility model
Fig. 3 is a vertical view of the present utility model
Fig. 4 is the N portion enlarged drawing among Fig. 2
Fig. 5 is the B portion enlarged drawing among Fig. 3
Below in conjunction with accompanying drawing the utility model is elaborated:
According to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4,1 is the coil rack body among the figure, on the skeleton body, up and down, front and back all are provided with some winding slots 3,4th of being separated by by intersegmental dividing plate 2, transition wire jumper groove, the bight of the close skeleton body 1 of this wire jumper groove, traverse winding slot 3, the cross section becomes " V " font, and its first groove face 5 is roughly the extended surface of winding slot 3 groove bottom, and second groove face 6 satisfies the wire jumper requirement by wire jumper groove " V " shape A/F and lay.
During coiling, for make the transition lead from the top of last winding slot backward at the bottom of the winding slot transition get nature, smooth and easy rationally, second groove face 6 of said wire jumper groove 4 can be the tangent plane of winding slot 3 bottom land moving pivots." V " shape channel opening angle is roughly 25 degree at this moment.
Avoiding wire jumper groove 4 " V " shape opening part winding wire to collapse under the precondition of line as far as possible, satisfy the requirement of wire jumper more fully for " V " shape A/F that makes wire jumper groove 4, said its first groove face 5 can be outward-dipping at the oral area of " V " shape opening.
In order to help the vacuum resin embedding, make the transformer coil can be with infiltration resin more equably, said skeleton can be provided with some vertical paint baths 5 that ooze on the intersegmental dividing plate 2 in both sides about in the of 1, as shown in Figure 5.
The utility model is reasonable in design, simple in structure, the transition lead can transit directly to the bottom of next winding slot from the tangential direction of the top of last winding slot figure skeleton along the line circular arc portion during coiling, the bottom electrical pressure reduction maximum of transition lead and last winding slot is with the upper voltage difference maximum of next winding slot.Therefore, the trend of the position of lead-over groove and transition lead all compares rationally, the transformer coil good insulation preformance.
