Abstract
The utility model relates to a novel pouring type current transformer secondary winding is fixed device. With epoxy will hoist with the bonding of inserts and secondary winding together, replace secondary hoist and mount frame, improved the stability of secondary coil hoist and mount in the mutual -inductor die -filling, reduced the drawing of patterns time, improved product quality. The effectual withstand voltage puncture hidden danger of having avoided between the winding in space between secondary winding.
Description
(1) technical field
The utility model is a kind of Novel pouring type current mutual inductor secondary winding fixture, belongs to high voltage line device field.
(2) background technology
Tradition pouring current transformer, by secondary winding wrapping mast-up, realizes secondary winding lifting in a mold.Because the position of mast-up and stability cannot be well controlled, to adjust each secondary winding time die-filling, ensure the requirement of an insulation distance between winding and secondary winding and between secondary winding, therefore extend the die-filling time.When solving the problem, secondary winding binding realizes by general employing.Withstand voltage for what ensure between secondary winding, need between secondary winding to be encased inside insulating board, but easily to cause between winding withstand voltage punctures.Therefore need the fixed structure researching and developing a kind of Novel pouring type current mutual inductor secondary winding badly, solve the deficiency of above-mentioned existence.
(3) summary of the invention
The object of the design is a kind of Novel pouring type current mutual inductor secondary winding fixtures of research and development, ensure secondary winding die-filling in have higher stability while to avoid again between winding withstand voltage punctures.
The design solves the technical scheme that its technical problem takes: secondary winding and lifting inserts are fixed together with epoxy resin.When instrument transformer is die-filling, directly inserts and mould are bolted connection, can complete secondary lifting, thus improve pouring current transformer die-filling time secondary winding stability; Vacate corresponding gap between secondary winding, ensure that compressive resistance between winding.
The beneficial effect of the design is: optimize insulation property, improves the rate of finished products of product; Shorten the die-filling time, improve operating efficiency.

In Fig. 11 be secondary winding 1., 2 be secondary winding 2., 3 is secondary winding gaps, 4 is bolts, and 5 is epoxy resin, and 6 is die cover plates, 7 is secondary wiring terminals, 8 be secondary winding 3., 9 is windings, and 10 is die side plates, 11 is frocks, 12 is inserts location holes, 13 be inserts 1., 14 be inserts 2..
(5) embodiment
Further illustrate below in conjunction with the concrete enforcement of accompanying drawing to device.
Inserts (13,14) and secondary winding (1,2,8) are positioned by frock (11), reserves 3 ~ 5mm gap (3) between secondary winding, then use epoxy resin (5) to pour into a mould.Just Fig. 2 parts can be obtained after epoxy resin (5) solidification.Complete with winding (9) assembly working after, carry out die-filling.Fig. 2 parts are fastened on die cover plate (6) with bolt (4) connection inserting part (13,14) and the fixing of secondary winding (1,2,8) can be completed.Inserts (13,14) is manufactured by the metal materials such as copper, iron, aluminium or alloy, and mould (6,10) is manufactured by pre-hardening plastic die steel.The centre distance of inserts (13,14) is consistent with the hole for hoist of die cover plate (6), is located by the inserts location hole (12) in frock (11).The endless number system of secondary winding and inserts (13,14).Implement by above-mentioned technological requirement and procedure, just can realize the utility model.
The utility model, improves the stability that secondary winding coordinates with mould, optimizes insulation property, improves the rate of finished products of product; Shorten the die-filling time, improve operating efficiency.
Claims (2)
1. a Novel pouring type current mutual inductor secondary winding fixture, primarily of secondary winding, epoxy resin and inserts composition, is characterized in that: secondary winding and inserts are fixed with epoxy resin.
2. Novel pouring type current mutual inductor secondary winding fixture according to claim 1, is characterized in that: inserts centre-to-centre spacing is identical with mould therefor installing hole centre-to-centre spacing, reserves space between secondary winding.
