Abstract
The utility model provides a wholly-bound iron core of a transformer, which mainly comprises a plurality of silicon steel sheets, two iron core splints, an adjusting cushion strip and an iron core binding belt. The innermost iron core is a step-shaped iron core sheet which is formed by accumulating the silicon steel sheets, wherein the iron core sheet is compressed by the two iron core splints at the two ends, and the adjusting cushion strip is cushioned at the outer part of the iron core sheet, so that the outer surface of the iron core is approximately circular. The outermost iron core is the iron core binding belt, wherein the iron core binding belt is a glass fiber binding belt, and the glass fiber binding belt is half overlapped and packed on the iron core with a certain tensile force to form into a rigid whole body. The wholly-bound iron core leads the iron core to be formed into a whole circle through the iron core splints and the adjusting cushion strip, leads the iron core to be tightly bound to form into the rigid whole body through the glass fiber binding belt, has the characteristics of simple structure and reliable binding, and can effectively solve the defect caused by binding the iron core through the existing transformer with the technical clamp.
Description
Technical field
The utility model relates to a kind of motor component, is specifically to use the whole dressing type iron core of transformer in a kind of electric locomotive, and the whole dressing type iron core of this kind transformer mainly is adapted at using on the dry-type transformer.
Background technology
Transformer core is a locomotive with a vitals on the dry-type transformer, is to adopt silicon steel sheet to be built up, and for piecemeal silicon steel sheet is closely superimposed together, work in-process need carry out colligation to this; Transformer core in the past all adopts the segmentation colligation, and manual operations does not have certain pulling force during the wrapping iron core, and the iron core bulk strength is not strong, and this iron core is only applicable to vertical transformer; The iron core that adopts the core through screw rod structure is also arranged in addition, promptly on silicon steel sheet, open some through holes, screw rod is passed through hole, silicon steel sheet is locked with nut at two again, this scheme will be considered the insulation between screw rod and the iron core, complex structure in addition because core through screw rod will take certain space.Therefore need further to be improved.
Summary of the invention
The purpose of this utility model in order to overcome existing locomotive with the deficiency in the dry type transformation iron core colligation processing, proposes a kind of colligation stability height exactly, and simple in structure, the whole dressing type iron core of the transformer that insulation effect is good.
The technical scheme that its technical problem that solves the utility model adopts is: the whole dressing type iron core of a kind of transformer, this dressing type iron core mainly are made up of silicon steel sheet, iron core clamping plate, adjustment filler strip, iron core binding strap.The stepped lamination that repeatedly amasss for silicon steel sheet of the inside, lamination is compressed by the iron core clamping plate at two ends, is lined with the adjustment filler strip again in the outside of lamination, makes core exterior surface be approximately circle.The iron core outermost layer is the iron core binding strap, and the iron core binding strap is a glass fiber winding tapes, and glass fiber winding tapes on iron core, forms a rigid unitary with certain pulling force half-stack package.
The utility model makes iron core form full circle by iron core clamping plate and adjustment filler strip, by glass fiber winding tapes iron core is tightened again and formed a rigid unitary, have simple in structurely, the colligation reliable characteristics uses these technology anchor clamps can effectively solve the defective of existing transformer core colligation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, iron core clamping plate; 2, silicon steel sheet; 3, adjust filler strip; 4, iron core binding strap.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the whole dressing type iron core of a kind of transformer, this dressing type iron core mainly are made up of silicon steel sheet 2, iron core clamping plate 1, adjustment filler strip 3, iron core binding strap 4.The stepped lamination that repeatedly amasss for silicon steel sheet 2 of the inside, the silicon steel sheet that silicon steel sheet 2 does not wait for thickness is built up, and the centre is the thickest silicon steel sheet, and ragged edge is the thinnest silicon steel sheet; Lamination is compressed by the iron core clamping plate 1 at two ends, is lined with the adjustment filler strip again in the outside of lamination, makes core exterior surface be approximately circular.The iron core outermost layer is the iron core binding strap, and the iron core binding strap is a glass fiber winding tapes, and the iron core binding strap on iron core, forms a rigid unitary with certain pulling force half-stack package.
