Abstract
The utility model relates to an integral combined insulation structure of a magnetic pole coil, which comprises a coil main body. The coil main body is a long strip body, and the two end parts are arc bodies; an epoxy glass grey cloth insulator is arranged between straight body parts of every two coils of copper lead wires of the coil main body, dry mica tape insulators are wound at the parts of the arc bodies at the end parts of the copper lead wires in wrapping and half-lap manners, and dry mica tapes which are wound at the parts of the arc bodies in wrapping and half-lap manners are connected with epoxy glass grey cloth at the straight body parts in an insulating manner; an upper supporting plate and a lower supporting plate are respectively arranged at the upper and lower end faces of the coil main body, and the coil main body forms a whole body with the upper supporting plate, the lower supporting plate and the insulators by hot pressing. The integral combined insulation structure has the characteristics that: the reliability of the insulation structure is improved, and the running quality of a machine unit is ensured; meanwhile, the utilization rate of insulation materials is greatly increased, turn-to-turn insulation punch dies at the end parts are saved, fiberglass dust and waste pollution caused in turn-to-turn insulation punching are eliminated, the manufacturing period of coils is shortened, and the labor intensity of workers is reduced.
Description
[technical field]
The utility model belongs to electrical equipment technical field, relates to a kind of pole coil entire combination insulation system that adopts complete insulation system between per two circle copper conductors.
[background technology]
At present, the edge-wind type field-turn insulation structure that hydraulic generator is used always is divided into two kinds: a kind of structure is to be lined with expoxy glass embryo cloth between per two circle copper conductors, and is hot-forming then; Another kind of structure be at every circle copper conductor half-stack package around mica paper tape, hot-forming then.Above-mentioned two kinds of structures all are to adopt insulation system between the part between per two circle copper conductors, are a kind of incomplete insulation systems, and this structure easily causes being short-circuited between the copper conductor, has seriously influenced the service life of unit.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of reliability that can reduce cost of manufacture, improve insulation system, has improved the pole coil entire combination insulation system of product quality.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pole coil entire combination insulation system, comprise coil body, this coil body is that both ends are the elongate body of arc body, between the stretched part of per two circle copper conductors of coil body, expoxy glass embryo cloth insulator is housed, arc body portion half-stack package in the copper conductor end is wound with the mica paper tape insulator, arc body portion half-stack package around mica paper tape and the expoxy glass embryo cloth of stretched part between insulation connect suitable, on coil body, the lower surface branch is equipped with mounting plate and bottom plate, coil body and mounting plate, bottom plate and insulator are in aggregates by hot pressing.
Inner face in described elongate body is provided with the insulation against ground body, and the expoxy glass embryo cloth of this insulation against ground body is by in aggregates with wraparound or hot pressing and coil body.
The beneficial effects of the utility model are: effected a radical cure pole coil turn-to-turn short circuit quality persistent ailment, improved the reliability of insulation system, guaranteed the unit operation quality; Simultaneously, increase substantially the insulating material utilance, saved end turn-to-turn insulation punch die, glass fiber dust that has been produced when having exempted the turn-to-turn insulation punching out and waste material pollute, and have shortened the manufacturing cycle of coil, alleviate labor strength.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-copper conductor, 2-expoxy glass embryo cloth insulator, 3-mica paper tape insulator, 4-mounting plate, 5-bottom plate, 6-insulation against ground body.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, a kind of pole coil entire combination insulation system, comprise coil body, this coil body is that both ends are the elongate body of arc body, inner face in this elongate body is provided with insulation against ground body 6, and the expoxy glass embryo cloth of this insulation against ground body 6 is by in aggregates with wraparound or hot pressing and coil body; Between the stretched part of per two circle copper conductors 1 of coil body, expoxy glass embryo cloth insulator 2 is housed, arc body portion half-stack package in copper conductor 1 end is wound with mica paper tape insulator 3, arc body portion half-stack package around mica paper tape and the expoxy glass embryo cloth of stretched part between insulation connect suitable, form a complete insulator, upper and lower end face packing in coil body has mounting plate 4 and bottom plate 5, mounting plate 4 and bottom plate 5 all adopt expoxy glass embryo cloth to make, and coil body and mounting plate 4, bottom plate 5 and insulator are in aggregates by hot pressing.The utility model has effected a radical cure pole coil turn-to-turn short circuit quality persistent ailment, improves the reliability of insulation system, guarantees the unit operation quality; Simultaneously, increase substantially the insulating material utilance, saved end turn-to-turn insulation punch die, glass fiber dust that has been produced when having exempted the turn-to-turn insulation punching out and waste material pollute, and have shortened the manufacturing cycle of coil, alleviate labor strength.
