The utility model is characterized in that the winding wires of the stator winding are copper flat wires adopting the outer-layer glass-fiber and film wrapping inner-layer H-grade insulation structure; a continuous structure of non-disconnection inter-pole idle wire is arranged between each stator winding; the stator winding is fixed on the stator winding core through an inter-pole supporting block and a supporting block insulation layer. The insulation improved structure has good insulation capacity, and the insulation structure can not be easily damaged. The short-circuit phenomenon can not easily generated between the inter-turn and the inter-layer. Thus the generator can work with high reliability.
Description
Technical field
The utility model relates to a kind of generator rotor structure, relates in particular to a kind of whole salient pole synchronous generator rotor winding construction.
Background technology
At present, the rotor winding of domestic salient-pole synchronous generator all adopts the coiling in whole salient pole rotor core of enamel-cover flat type copper wire.When coiling, whenever around one deck coating one deck quick-drying paint, during coiling bottom coil, the radius of turn at coil two ends is less, and naked copper the crack appears and in the insulation enamelled coating of enamelled wire easily in the shaping.Though, also have turn-to-turn short circuit and layer short circuit hidden danger through mopping.When generator is standby, most of time motors do not turn round, rotor winding enamelled coating crack place makes moist and produces chemical corrosion, in case during generator operation, and then generation galvanic corrosion, make insulation damages place local overheating, constantly enlarge turn-to-turn and the layer insulation of damaging winding, cause turn-to-turn, layer short circuit at last, until shorted to earth, burn motor.This type of rotor winding insulation fault accounts for the generator total failare more than 50% at present.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of whole salient pole synchronous generator rotor winding insulation structure-improved, and its good insulation preformance, insulation system are not fragile, and turn-to-turn and interlayer are difficult for producing short circuit phenomenon, generator operation reliability height.
To achieve these goals, the utility model provides a kind of salient-pole synchronous generator rotor winding insulation structure, comprise: rotor winding, the whole salient pole rotor core of wrapping pole(cell) insulation, its characteristics are: the coiling lead of described rotor winding is for adopting the copper strap wire of glass fiber skin and the wrapped internal layer H of film class F insulation structure, for not disconnecting the continuous structure of interpolar intercoil connection, described rotor winding is fixed in the described rotor core by interpolar bracer and bracer insulating barrier between each extremely described rotor winding.
Above-mentioned salient-pole synchronous generator rotor winding insulation structure, its characteristics are: described interpolar bracer is the wing aluminum bracer of segmentation.
Above-mentioned salient-pole synchronous generator rotor winding insulation structure, its characteristics are: be connected and fixed by a stud between the adjacent described wing aluminum bracer.
Above-mentioned salient-pole synchronous generator rotor winding insulation structure, its characteristics are: described interpolar insulating layer is a H level composite insulating foil bed course.
Above-mentioned salient-pole synchronous generator rotor winding insulation structure, its characteristics are: the insulated binding structure is adopted in the end of described rotor winding.
Above-mentioned salient-pole synchronous generator rotor winding insulation structure, its characteristics are: the insulated binding structure is adopted in the end of described rotor winding.
Because the utility model has adopted above-mentioned rotor winding insulation structure; by in the whole salient pole rotor core of wrapping pole(cell) insulation, adopting the wrapped copper strap wire of glass fiber bag film to replace traditional enamel-cover flat type copper wire; turn to the generator amature winding; salient-pole synchronous generator rotor winding coil turn-to-turn and layer insulation protection in coiling and running have been strengthened; thereby improved anti-dust of winding and assorted dirty ability, improved the generator operation reliability.
Further specify specific embodiment of the utility model below in conjunction with accompanying drawing
Description of drawings Fig. 1 is that a kind of salient-pole synchronous generator rotor winding insulation structure chart 2 shown in the utility model is that to adopt schematic diagram Fig. 3 of the wrapped flat type copper wire of glass fiber bag book film in Fig. 1 rotor winding be that Fig. 1 rotor winding fixed structure schematic diagram Fig. 4 that insulate in iron core is that interpolar bracer schematic diagram Fig. 5 is that vertical view Fig. 6 of Fig. 4 is that rotor windings at different levels company is around structural representation among Fig. 3
Embodiment
In Fig. 1,2,3,4, Fig. 5 and Fig. 6, a kind of salient-pole synchronous generator rotor winding insulation structure that the utility model is designed comprises: the rotor core 1 of whole salient-pole synchronous generator, pole(cell) insulation 2, rotor winding 3, bracer insulation 4, interpolar bracer 5 and stud 6.Wherein, in Fig. 1, end banding structure 31 is also adopted in the end of rotor winding 3.In Fig. 2, Fig. 3 and Fig. 6, in the whole salient pole rotor core 1 of wrapping the pole(cell) insulation pad, adopt the wrapped flat type copper wire of H level glass fiber bag film, arbitrary extremely on by technological requirement by circle, successively around the rotor winding of an intact utmost point, go to consecutive roots then, coil winding machine counter-rotating, by circle, successively around intact consecutive roots winding, so with each utmost point rotor winding around finishing, reserve lead-out wire, the good end of colligation.In Fig. 4 and Fig. 5, interpolar is equipped with the wing aluminum bracer 51 of segmented, and the bracer insulation 4 between the coil of aluminum bracer 51 and rotor winding 3 adopts pad H level composite insulating foil mode as insulation against ground.In Fig. 2, adopted the wrapped flat type copper wire wound rotor of glass fiber bag film winding on the whole on the field spider iron core, it is wrapped that promptly the coiling lead internal layer of rotor winding adopts film, the outer glass fiber bag that adopts.In Fig. 6, every utmost point winding of rotor winding connect around, do not disconnect the interpolar intercoil connection.
The insulation structure for convex pole synchronous generator rotor winding of the utility model design and at present close its His other structures are compared, and have following advantage: 1, because glass fiber bag Transposed wind flat type copper wire Proof voltage intensity and bending resistance, tensile strength all double above than enamel-cover flat type copper wire, therefore having solved turns to Occur easily turn-to-turn and layer short circuit problem in sub-winding technique process and the running, improved generating The machine operational reliability. 2, needn't every layer of mopping in coiling, the special use that does not also need Heat preservation around Line equipment, technological operation is easy. 3, can be every utmost point winding connect around, needn't resemble traditional winding in Fig. 3 The lead that inserts from a point disconnects the interpolar intercoil connection at b, c and d, has eliminated the interpolar Connecting line joint The hidden danger of loose contact. 4, the anti-dust of winding and assorted dirty energy force rate enamel-covered wire are strong, are suitable for many dust Adverse circumstances are used. 5, the wing aluminum bracer of segmented is convenient to rotor wire thermal expansion in service, Be difficult for squeezing broken insulation against ground.
This structure can be widely used in CM series no-brush synchronous generator (20 ~ 1200KW).
