Abstract
The invention discloses epoxy coating paper. The epoxy coating paper is provided with insulating paper; a coating layer is arranged on the outer surface of the insulating paper; the coating layer is made from special modified epoxy resin; and the special modified epoxy resin comprises the following ingredients in parts by weight: 45-55 parts of 0194 epoxy resin, 15-25 parts of F46 epoxy resin, 10-20 parts of 601 epoxy resin, 5-15 parts of 594 curing agent and 3-7 parts of diamino diphenyl sulfone. By adoption of the epoxy coating paper, the voltage withstand level of layer insulation of an oil-immersed transformer can be improved, the dielectric loss can be reduced, the structural strength of the transformer coil can be strengthened, the operating reliability of the transformer can be improved, and the production cost of the oil-immersed transformer can be lowered.
Description
Technical field
The disclosure relates generally to field transformer, is specifically related to transformer insulating paper field, particularly relates to a kind of epoxy coated paper。
Background technology
The generally individually employing cable paper of oil-immersed power transformer winding coil layer insulation。The current main cable paper specification used has 0.08mm and 0.13mm two kinds。In the production of transformator, use specification kind to reduce cable paper as far as possible, it is simple to buying produces。Current in transformer production industry, typically each adopt 0.08mm cable paper to carry out using and cable paper number to choose general be that 4.75kV/ opens with reference to its breakdown voltage after immersion oil, thus causing each winding coil interlayer to be dielectrically separated from by the cable paper of multilamellar, but traditional winding construction causes when laying cable paper, owing to winding coil structure design is unreasonable, thus causing that cable paper makes large usage quantity when meeting class of insulation needs。On the one hand becoming the waste of cable paper, also resulting in transformer winding structure volume on the other hand increases, thus affecting overall structure and the deadweight of transformator, production cost is consequently increased, and also leads to that temperature rise when transformator runs is notable and radiating effect is poor simultaneously。
Summary of the invention
In view of drawbacks described above of the prior art or deficiency, it is desirable to provide and a kind of reduce transformer production cost, improve the epoxy coated paper in transformator service life。
First aspect, a kind of epoxy coated paper, epoxy coated paper is provided with insulating paper, and insulating paper outer surface is provided with dope layer, and dope layer is special modified epoxy resin, counts by weight, and special modified epoxy resin comprises following components:
0194 epoxy resin: 45～55 parts,
F46 epoxy resin: 15～25 parts,
601 epoxy resin: 10～20 parts,
