Abstract
The utility model discloses an insulating end ring for a resin pouring-type transformer high-voltage coil, and pertains to the field of substation equipment. The insulating end ring for a resin pouring-type transformer high-voltage coil comprises a high-voltage coil and insulating end rings arranged at two ends of the high-voltage coil. The insulating end ring is internally provided with an epoxy glass laminated sheet insulating ring. Compared with the prior art, the insulating end ring for a resin pouring-type transformer high-voltage coil has the advantages that the design is reasonable, the structure is simple, processing is easy; the distance between the high-voltage coil and a yoke is shortened, cost is saved, loss is reduced, and the discharge phenomenon due to crack of the insulating end ring can be effectively avoided.
Description
Technical field
The utility model relates to converting equipment field, specifically cast-resin type transformer high-tension coil insulating end ring.
Background technology
The insulating end ring of conventional 10kv resin casting dry-type transformer high-tension coil is by the thick glass fiber felt of 15mm or glass grid cloth, to make filler to make, and this insulating end ring distance Iron yoke is 40-45mm, the excessive cost that increased of distance; Because thereby this insulating end ring is in cast easily cracking guiding discharge afterwards, cause security incident.
summary of the invention
Technical assignment of the present utility model is for above weak point, provide a kind of simple in structure, production cost is low, be easy to processing, environmentally safe cast-resin type transformer high-tension coil insulating end ring.
The utility model solves the technical scheme that its technical problem adopts: the insulating end ring that this cast-resin type transformer high-tension coil comprises high-tension coil and is arranged on high-tension coil two ends with insulating end ring, insulating end ring is filled and is made by glass felt or glass tape, is provided with epoxy resin bonded fiber insulated ring in insulating end ring.
Cast-resin type transformer high-tension coil of the present utility model with insulating end ring compared to the prior art, have reasonable in design, simple in structure, be easy to the features such as processing, not only can shorten the loss of having saved cost of distance between high-tension coil and iron yoke, but also effectively avoid the phenomenon of insulating end ring cracking guiding discharge.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is the structural representation of cast-resin type transformer high-tension coil with insulating end ring.
Accompanying drawing 2 be in accompanying drawing 1 A-A to structural representation.
In figure: 1, high-tension coil, 2, insulating end ring, 3, epoxy resin bonded fiber insulated ring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Cast-resin type transformer high-tension coil insulating end ring of the present utility model, the insulating end ring 2 that its structure comprises high-tension coil 1 and is arranged on high-tension coil 1 two ends, insulating end ring 2 is filled and is made by glass felt or glass tape, in insulating end ring 2, be provided with epoxy resin bonded fiber insulated ring 3, insulating end ring 2 is interior to be arranged after epoxy resin bonded fiber insulated ring 3, shorten the distance of high-tension coil 1 end distance Iron yoke, also avoided high-tension coil 1 to cause because pouring into a mould the electric discharge phenomena that end cracking causes simultaneously.
Cast-resin type transformer high-tension coil of the present utility model is very simple and convenient with its processing and fabricating of insulating end ring, processing and fabricating shown in by specification accompanying drawing.
Except the technical characterictic described in specification, be the known technology of those skilled in the art.
