Description
Technical field
The invention belongs to generating equipment turbo generator technical field, is a kind of high-capacity non-salient pole chip type synchronous generator rotor.
Background technology
In technique known, the rotor of employing is divided into two kinds of salient pole and non-salient poles usually, and salient-pole structure adopts centralized winding, and Inside coil is concentrated, and radiating effect is bad.Simultaneously, main abutment surface arc guarantees the waveform of generating, be difficult for reaching perfect condition, and degree of protection is low, the highlyest can only reach the IP44 level.Thereby non-salient pole structure, the examination winding that distributes are generally paid attention to and are progressively promoted at present.But the armature spindle of this setted structure generally adopts the mode of solid forging cutting fluting to make.Because rotor is a slim-lined construction, thereby the production and processing cycle is long, operation is many, cost is high, the manufacturing process complexity, and also stock utilization is low.In order to improve the heat dispersion of rotor, normally at the Surface Machining heat radiation ditch of rotor shaft, the row of rotating shaft internal heat looses and only depends on conduction pattern to reach rotor surface, therefore, heat dispersion does not reach desirable requirement, thereby has influenced the operate as normal of rotor and the quality of generator product.In addition, the generator cooling fan adopts the shell type coil brace to be installed in the rotating shaft, because of mounting structure is limit, flabellum air inducing radius is little, causes the cooling air quantity deficiency, can not satisfy the cooling needs, and flabellum is strengthened, can make flabellum rigidity deficiency when operation again, damage easily.
Secondly, the rotor of prior art adopts single damping usually, and damping is bad, when using extraneous gauze to power excitation, owing to voltage, capacitance fluctuations are disturbed greatly easily.When the abnormal running state particularly occurring, generator is stablizing of recovery system rapidly, influences the production power supply quality of this machine.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, ventilation and heat is good, damping is good non-salient pole chip type synchronous generator rotor.
Realize that the technical scheme that purpose of the present invention is taked is: the iron core of rotor adopts grouping nest plate type structure, be to be contained on the rotor shaft by the folded chuck of a plurality of rotor punching groupings, and the end clamp plate and the screw rod that are provided with by two ends compress, be provided with the tooth support of band radial ducts between every group rotor punching, have the axial ventilation groove on the rotor shaft, this groove is communicated with air duct on the tooth support, and the rotor coil end is provided with the rotor center ring of belt coil support, and is set with the rotor end bell of band ventilation hole.
Described rotor core is provided with two damping circuits, and one is connected and composed by amortisseur bar on the rotor canine tooth and end clamp plate, and another is connected and composed by rotor end bell and slot wedge.
Be laid with a plurality of ventilation holes on the coil brace of described rotor center ring, this ventilation hole is connected with the axial ventilation groove of rotor shaft.
On the described rotor center ring cooling fan is housed.
The generator amature of making according to such scheme, adopt grouping nest plate type structure, and between the nest plate group and rotor tip set up the cooling duct, not only improved the ventilation and heat condition of rotor greatly, interior each member of rotor can both effectively be cooled off, and can avoid the damage of coil covering and other member.In addition, on armature spindle, be provided with two damping circuits, can guarantee that generator is in good running status all the time, and can improve the reliability of electrogenesis quality and generator operation.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, high-capacity non-salient pole chip type synchronous generator rotor of the present invention adopts grouping nest plate type structure, this structure is to be contained on the rotor shaft 1 by the folded chuck of a plurality of rotor punching 3 groupings, each organizes the tooth support 11 that all clamps between the punching 3 with a plurality of radial ducts, constitute the nest plate type rotor core, iron core is compressed by end clamp plate 6 and screw rod 7.Have axial ventilation groove 12 on the rotor shaft 1, and be communicated with air duct on the tooth support 11, in the generator operation process, refrigerating gas is entered by ventilation slot 12 two ends, air duct through tooth support 11 flows into air gap, and is back in the cooler by the radially air-return duct of stator.Can make rotor coil 2 and rotor punching 3 receive good result of ventilating heat dissipation.On rotor center ring 8, have coil brace 9, rotor coil 2 ends are clamped between coil brace 9 and the retaining ring 4 securely, be used to protect rotor coil 2 unlikely damages on the one hand, can strengthen the stationarity of rotor running on the other hand.Rotor tip is the position that heat is comparatively concentrated, therefore on the coil brace 9 of rotor end bell 4 and centering ring 8, be laid with a plurality of ventilation hole 4a, 10, and be connected with the axial ventilation groove 12 of rotor shaft 1, the refrigerating gas in air intake district is at first cooled off rotor tip by the axial ventilation groove 12 of rotating shaft 1 and the radial ventilation hole of tooth support 11.Rotor is provided with two damping circuits, and wherein one is made of with rotor-end pressing plate 6 amortisseur bar 13 that is installed on the rotor canine tooth, and another is connected and composed by rotor end bell 4 and slot wedge close-fitting.Like this, electricity generation system of short duration beat the time, can lean on the hindrance function of rotor self to reduce influence of fluctuations and make generator operation recover normal rapidly.In addition, in order to reduce the axial vibration in cooling fan 5 operation process, cooling fan 5 is directly installed on the rotor center ring 8, makes structure compact more.
