Abstract
The utility model discloses a bearing structure of transformer winding. The existing structure has low mechanical strength. The winding stay is comb-shaped, and comprises an integrated comb back, comb teeth and comb grooves formed between adjacent comb teeth, wherein the tops of the comb teeth are in a round angle shape. When the comb back is arranged, the comb back is fastened on the hard material insulating cylinder, the winding coil is wound in the comb groove, and the comb teeth form an oil passage or an air passage between each section of winding. The product is an integral body and has high mechanical strength, and the comb-shaped winding stay is rigidly connected with the hard material insulating cylinder and forms a firm integral body with the conducting wire, thereby greatly improving the mechanical strength of the winding and improving the winding efficiency.
Description
The utility model is the supporting construction of Transformer Winding, is specially the stay of Transformer Winding.
Existing Transformer Winding supporting construction sees shown in Fig. 1-3, and it is to make stay 1 or 3 as vertical skeleton and be fixed on the soft or rigid paper web 5 with papery or other insulating material; Be fastened with horizontal tail cushion block 2 or dove tail cushion block 4 at interval on the stay 1 or 3, make and form oil duct or air flue between each section winding 6.Stay and cushion block constitute the support frame of Transformer Winding, and each section (or circle) winding all is fixed at vertical and horizontal.This structure is widely used in oil immersed type or the dry-type transformer, and its weak point is that support frame is combined by the stay and the cushion block that separate, thereby at the bottom of the mechanical strength, the electroshock power of the generation when being difficult to bear transformer short-circuit.
The purpose of this utility model provides the high Transformer Winding stay of a kind of mechanical strength.
Structure of the present utility model is: whole winding stay is comb shape, includes the comb groove that forms between the incorporate comb back of the body, broach and adjacent fingers.Preferably make the top of broach be the fillet shape, the insulation of damage wires when avoiding winding the line.To comb the back of the body during arrangement and be anchored on the hard material insulating cylinder with insulated bolt, insulated rivet, viscose glue or bayonet socket etc., around going into winding coil, broach just forms oil duct or air flue between each section winding in the comb groove.How many sizes of broach and comb groove is by the size of winding conducting wire and deciding of wire turn.
The utility model winding stay adopts insulating material to make usually.When the turn insulation intensity of winding conducting wire was enough to tolerate the winding insulation against ground, the utility model winding stay also can adopt metal material to make.After using the utility model, the technique for coiling of winding is different when using traditional winding support frame also.In the continous way winding technique, can not adopt the method for positive section and the section of turning over, and the technique for coiling that just directly adopts section, thereby increase work efficiency greatly.
The utility model has the advantages that product is originally as an integral body, mechanical strength height; And comb shape winding stay and hard material insulating cylinder be rigid to be connected and lead forms firm integral body, has improved mechanical Strength for Winding greatly, not yielding or damage under powerful electrodynamic action; Can improve coiling efficient in addition.
Fig. 1 is existing a kind of Transformer Winding supporting construction.
Fig. 2 is existing another kind of Transformer Winding supporting construction.
Fig. 3 is that the mutual alignment of winding support structure shown in Figure 1 and paper web and winding concerns schematic diagram.
Fig. 4 is the structural representation of embodiment, and wherein A is main looking, and B is for overlooking.
When Fig. 5 is the use of embodiment winding stay and the mutual alignment of hard material insulating cylinder and winding concerns schematic diagram.
Embodiment: see Figure 4 and 5.The whole winding stay that adopts insulating material to make is comb shape, and the comb groove 9 that is formed by the incorporate comb back of the body 7, broach 8 and 8 of adjacent fingers is constituted.The top 10 of broach 8 is the fillet shape.To comb the back of the body 7 during arrangement and stick with glue and be fixed on the hard material insulating cylinder 11, in comb groove 9 around going into winding coil 12.The degree of depth h of comb groove 9 is higher 15 millimeters than the thickness of winding coil 12.The width a of the width b of broach 8 and comb groove 9 is more bigger than the width of winding 12.
Above embodiment is only in order to be further described the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
Claims (2)
1, a kind of Transformer Winding stay of comb shape is characterized in that whole winding stay is comb shape, includes the comb groove that forms between the incorporate comb back of the body, broach and adjacent fingers.
2,, it is characterized in that the top of broach is the fillet shape as the said Transformer Winding stay of claim 1.
