Abstract
The utility model relates to a kind of transformer static board structure, have static board skeleton, adopt copper electric brush wire to go between as static board, the leading point of static board lead-in wire is arranged on winding protruding head place, static board skeleton is opened lead-in wire wire hole, and static board lead-in wire is fixed on skeleton.The utility model avoids static board lead-in wire and coil first cake wire bonds, and it is radial that solder joint exceeds coil, causes internal field to distort, and the coil that may cause pollutes.
Description
Technical field
The utility model relates to technical field of transformer manufacturing, specifically a kind of transformer static board structure.
Background technology
The electric utility develop rapidly of current China, the demand of power transformer is surged, and also proposes higher requirement to its output and quality.
Along with power transformer capacity is increasing, electric pressure is more and more higher, and the requirement of the security reliability of product is higher.Electric Field Distribution plays vital effect for the performance of high pressure, extra-high voltage transformer product, and static board is except improving Analysis of End Electric Field, makes outside main insulating structure declines to some extent, still to improve significantly to the turn-to-turn Potential distribution of First Line cake.How simplifying static board structure, ensureing that static board quality is significant to improving the quality of products.
Current static board structure adopts employing 1 × 8 soft copper lenticular wire TBR as short-circuited conducting sleeve; 1.4 × 5 copper strap wire TBR are welded on the lead-in wire as static board on short-circuited conducting sleeve; static board lead-in wire and coil first cake wire bonds, solder joint usually can be radial higher than coil, causes internal field to distort.Adopt the mode that static board lead-in wire is directly colded pressing with winding protruding head, there are two hidden danger in this scheme: the first for this reason, and the leading point of static board lead-in wire also affects coil internal field higher than coil is radial; The second, static board lead-in wire may cause static board wire breaking when winding protruding head is stressed, static board is suspended and lost efficacy.
Utility model content
Affecting coil internal field, winding protruding head for the leading point of static board lead-in wire in prior art causes static board wire breaking to make the deficiencies such as static board suspension inefficacy time stressed, the technical problems to be solved in the utility model is to provide a kind of transformer static board structure that internal field's distortion and coil can be avoided to pollute.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of transformer static board of the utility model structure, has static board skeleton, adopts copper electric brush wire to go between as static board, and the leading point of static board lead-in wire is arranged on winding protruding head place, and static board skeleton is opened lead-in wire wire hole, and static board lead-in wire is fixed on skeleton.
In the breach that namely described winding protruding head place opens for winding protruding head on static board.
Described copper electric brush wire is 6mm
2.
The utility model has following beneficial effect and advantage:
1. the leading point that static board goes between is adjusted near winding protruding head by the utility model, and avoid static board lead-in wire and coil first cake wire bonds, it is radial that solder joint exceeds coil, causes internal field to distort, and the coil that may cause pollutes.
2. the utility model opens lead-in wire wire hole on static board skeleton, by static board lead-in wire be fixed on skeleton, a nearly step avoid winding protruding head stressed time cause static board wire breaking.
3. the utility model decreases the production efficiency that solder joint improves coil.
Accompanying drawing explanation
Fig. 1 is static board skeleton structure schematic diagram in the utility model:
Fig. 2 is static board lead-in wire lead-out mode schematic diagram in the utility model.
Wherein, 1 is static board skeleton, and 2 is static board lead-in wire, and 3 is leading point.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, 2, a kind of transformer static board of the utility model structure, there is static board skeleton 1, adopt copper electric brush wire as static board lead-in wire 2, the leading point 3 of static board lead-in wire 2 is adjusted to winding protruding head place, static board skeleton 1 is opened lead-in wire wire hole, static board lead-in wire 2 is fixed on static board skeleton 1; In the breach that namely winding protruding head place opens for winding protruding head on static board.
The utility model adopts 6mm
2copper electric brush wire TS replaces 1.4 × 5 copper strap wire TBR as static board lead-in wire 2, makes static board lead-in wire 2 more easily bend distortion, ensures that static board lead-in wire 2 can be colded pressing or weld together with winding protruding head.Also suitably can reserve wish degree to avoid causing static board lead-in wire 2 fracture when winding protruding head is stressed.The leading point 3 of static board lead-in wire 2 is adjusted near winding protruding head simultaneously, is namely in the breach opened of winding protruding head at static board, avoids the leading point of static board lead-in wire 2 higher than the radial impact on coil electric field of coil.Simultaneously on static board skeleton 1, open lead-in wire wire hole, static board lead-in wire 2 be fixed on static board skeleton 1, a nearly step avoid winding protruding head stressed time cause static board to go between 2 fractures.
The static board structure of this improvement to be suitable in the product of model for SSZ-180000/220, and product testing is qualified.
Claims (3)
1. a transformer static board structure, have static board skeleton, it is characterized in that: adopt copper electric brush wire to go between as static board, the leading point of static board lead-in wire is arranged on winding protruding head place, static board skeleton is opened lead-in wire wire hole, and static board lead-in wire is fixed on skeleton.
2. by transformer static board structure according to claim 1, it is characterized in that: in the breach that namely described winding protruding head place opens for winding protruding head on static board.
3., by transformer static board structure according to claim 1, it is characterized in that: described copper electric brush wire is 6mm
