Abstract
The utility model relates to a novel pouring type voltage transformer is insulating device. Insulating skeleton with epoxy, silicon powder mixture are poured into a mould replaces traditional primary winding skeleton, is out and makes major insulation in addition, has improved work efficiency, has improved the partial discharge effect. Insulating framework two ends's step and surperficial sand -blast treating, effectual increased with mutual -inductor finished product casting material's area of contact and bonding strength.
Description
(1) technical field
The utility model is a kind of seal of Novel pouring formula voltage transformer, belongs to high voltage line device field.
(2) background technology
Enough insulation are needed, to bear the compressive resistance of standard-required between one secondary winding of tradition casting type voltage mutual inductor.The processing mode of existing instrument transformer is after being wound around enough insulating papers substantially, then casting epoxy resin, silicon powder epoxy glue.But because epoxy glue viscosity is comparatively large, insulating paper interlayer spacings can not be penetrated into fully, if vacuum, dry process is insufficient very easily leaves over bubble and moisture, cause mutual inductance general ability to put value excessive, even high-voltage breakdown.Therefore need a kind of novel casting type voltage mutual inductor insulation system of research and development badly, solve the deficiency of above-mentioned existence.
(3) summary of the invention
The object of the design is a kind of novel casting type voltage mutual inductor insulation systems of research and development, after carrying out simple drying, vacuum treatment to semi-finished product, can ensure that voltage transformer partial discharge quantity reaches standard-required.
The design solves the technical scheme that its technical problem takes: with epoxy resin, silicon powder epoxy glue for raw material, pour into the insulation framework of cylindrical structure, coiling winding in insulation framework, simultaneously insulation framework is as a dielectric between winding and secondary winding, then assembles with secondary winding and iron core.The entity structure of insulation framework, avoids because vacuum, drying process insufficient, causes and leave over bubble and moisture, causes mutual inductance general ability to let slip large and high-voltage breakdown.In addition, insulation framework two ends become step shape, and surfaces externally and internally blasting treatment, effectively add and the contact area of instrument transformer mould material and bond strength.
The beneficial effect of the design is: simplify production technology, improves operating efficiency; Improve the partial discharge of instrument transformer, improve the rate of finished products of product, reduce the potential faults of casting type voltage mutual inductor.
(4) accompanying drawing explanation
Fig. 1 is Novel pouring formula voltage transformer seal profile.
Fig. 2 is Novel pouring formula voltage transformer seal insulation framework profile.
In Fig. 1,1 is a winding, and 2 is insulation framework, and 3 is secondary winding, and 4 is C cores.
(5) embodiment
Further illustrate below in conjunction with the concrete enforcement of accompanying drawing to this seal.
By casting epoxy resin, silicon powder compound, the insulation framework (2) of mould molding cylindrical structure, two ends become step shape, surface sand-blasting process, and thickness, internal-and external diameter can according to instrument transformer product parameters and voltage withstand class variations.Using insulation framework (2) as skeleton, outside coiling winding (1), secondary winding (3) is put into skeleton endoporus, and two lobe C cores (4) are inserted secondary winding (3) endoporus, packing C core, can complete assembling.
The utility model eliminates the operation insulated between special coiling winding (1) and secondary winding (3), simplify production technology, when eliminating insulating paper as insulation between a winding (1) and secondary winding (3), because vacuum, drying process insufficient, cause the hidden danger leaving over bubble and moisture.
Claims (2)
1. a Novel pouring formula voltage transformer seal, primarily of insulation framework, winding, a secondary winding and C core composition, it is characterized in that: coiling winding in insulation framework, in insulation framework endoporus coiling secondary winding, C core is assemblied in secondary winding endoporus.
2. Novel pouring formula voltage transformer seal according to claim 1, it is characterized in that: insulation framework is adopt the insulation framework by epoxy resin, silicon powder epoxy glue moulding by casting, insulation framework is cylinder mode, two ends are step shape, surfaces externally and internally blasting treatment.
