Alternator shaft excitation end latch-up structure is by the lower plate (18) that is fixed on pedestal bearing (2) end face, train wheel bridge (19) clamping alternator shaft excitation end-journal (20).
The fixture structure of being made up of jointly alternator shaft shaft coupling end latch-up structure (4) and alternator shaft excitation end latch-up structure (5) to rotor (3) is simple; Reliable for effect; Be convenient to install and disassemble, disassemble process and also needn't disassemble other parts of generator.Latch-up structure has utilized generator to be positioned near the alternator shaft of pedestal bearing end face as ' locked ' zone, is the most succinct locking scheme reliably, and is designed to the thin type structure that can be held by the confined space, holding power also can satisfy instructions for use.Need disassemble other structure of generator and construct or support hypodynamic problem if adopt other position or structure then can produce.
The reverse automatic disengaging protection dynamic panel bassinet structure of tooth inserted tooth structure (6) is made up of triangular tooth jaw clutch clutch plate (21), triangular tooth jaw clutch driving disc spacing pressing (22), pneumatic actuator (23), travel switch (24).Alternator shaft (3) end face is connected with triangular tooth jaw clutch clutch plate (21); Triangular tooth jaw clutch driving disc spacing pressing (22) is installed on the pneumatic actuator (23); Travel switch (24) is positioned at the bottom of triangular tooth jaw clutch driving disc spacing pressing (22); The output signal is transferred to pneumatic actuator (23), has realized the automatic disengaging of barring structure and alternator shaft, avoids barring structure to be driven and the generation accident that runs up by alternator shaft.
Stator shunt leads sliding support pin assembly (7) is made up of supporting pin (25), generator unit stator shunt leads support (26), electricity generator stator stand end plate (27), bolt (28).The pin of supporting pin (25) is inserted in generator unit stator shunt leads support (26) hole, and the taper pin end of supporting pin (25) is inserted in electricity generator stator stand end plate (27) hole, and bolt (28) is fixed on supporting pin (25) on the electricity generator stator stand end plate (27).In some production processes and in the transportation, can convert release condition into, make this bracing or strutting arrangement lose the radial constraint effect, avoid the relative displacement of vibration force and elastic support structure to damage other structure of generator through this supporting construction.Under the guiding function of the taper pin end of supporting pin (25), revert to stationary state by release condition and can guarantee to revert to initial rigging position, reach the fixed effect of initial loading timing.
How forming feasible overall structure is new design problem; Hydrogen cooled generator is integrally-built generator; Generator of the present invention is that employing is air cooled; It here is uneconomic adopting the such end-cover axle bearing structure of hydrogen cooled generator here, because this hydrogen cooled generator needs complicated oil seal structure to prevent bearing oil to the generator internal leakage, makes generator and auxiliary system too complicated; Cause and install that cost improves and operation monitoring complicacy and operating cost improve, lose adopt the air cooling generator mechanism simple, build power plant and the low advantage of operation maintenance cost.Forming the integral installation platform method with the steel underframe is middle and small motor method commonly used; But the non salient pole generator that the present invention relates to belongs to the high-rating generator category; With the steel underframe here also is inadvisable must the design, because the overall weight of generator reaches hundreds of tons, the steel underframe must have enough rigidity; Otherwise in lifting and installation process, can't resist the deadweight of generator unit stator and rotor and produce distortion; Correct installation in position, can satisfy the steel underframe of rigidity requirement weight and height, width all must be very big, this just brings two unacceptable results: one is that the deadweight of generator unit stator and rotor is all very big; Add the weight of steel underframe; The total weight of the generator that forms can surpass the limit of highway and railway transportation, is that the height of steel underframe can improve generator overall height and centre of rotor height again, is not easy to mate with prime mover; The hidden danger that also causes operational shock to exceed standard easily, too high generator overall height also can exceed the building line of transport pathway bridge and can't realize transportation.
So forming feasible overall structure at first is to satisfy the primary demand of generator, reaches normal specification requirement; Reliable, can Rational structure mate with prime mover, be convenient to power plant's civil Engineering Design; Easy to use, the restrictive condition of transportation also must satisfy, otherwise can't transport.The overall dimension that makes the integrated generator machine is compact as far as possible, total weight is as far as possible for a short time is the successful key of design.
The rotor string is moving when preventing to transport causes that damage generator parts also are the new problems of the one-piece type non salient pole generator of design.Because the rotor weight of jumbo non salient pole generator reaches tens of tons and adopt the sliding bearing of no axial limiting to support; It implements axial limiting by prime mover, and rotor can relative stator freely be gone here and there before being connected with prime mover, does not transport if do not adopt an effective measure; It is moving that the collision of jolting of transportation can produce the rotor inertia string; Cause inner other structure of generator to collide each other, cause damage, and the bearing shell of generator does not have replenishing of lubricating oil in transportation; The inertia string moves and also can cause the dry friction of axle journal and bearing shell wriggling, grinds and hinders bearing shell.Cause that damage generator parts also are the new problems of the one-piece type non salient pole generator of design so the rotor string is moving when preventing to transport, the design of the locking device of rotor reliable fixation is suggested, and must be feasible, reliable, easy mounting and dismounting.This locking device also must or interfix on the position to axial that requires the rotor and the stator of generator, simplifies the installation steps that arrive after the power plant.
One-piece type non salient pole generator has also required reliable barring structure; Its effect is that the rotating shaft that in generating set is shut down back a period of time, drives generating set is slowly rotated; Avoid overheated prime mover rotating shaft generation permanent bend, the rotating shaft that also requires barring structure to drive generating set when playing machine is slowly rotated a period of time, when prime mover raising speed surpasses the jiggering rotating speed; Barring structure must be thrown off with the rotating shaft of generating set; Otherwise prime mover drives barring structure and rotates, and will cause the barring structure rotation of overrunning, and causes the accident.Because the turn up per minute 3000 of one-piece type non salient pole generator changes, the clutch driving plate of barring structure and the diameter of clutch plate can not be excessive, otherwise can bring very big wind moussing loss and noise.
Non salient pole generator often is the peaking operation mode; The generator of peaking operation often plays shutdown; Stator winding is different with the out frame material, and influence of temperature change can cause axially and relatively move, thus the stator winding shunt leads can not directly be fixed on the out frame; Can produce very big thermal stress like this, damage dependency structure.Must adopt a kind of effect of contraction is arranged diametrically and allows support in the supporting construction that axially relatively moves.And require this supporting construction can realize the conversion of stationary state and release condition easily, revert to stationary state by release condition and must guarantee it is initial rigging position, otherwise do not reach the fixed effect of requirement.This supporting construction will be in release condition in some production processes and in the transportation; Promptly lose the radial constraint effect; The relative displacement of avoiding vibration force and elastic support structure damages the stator winding shunt leads through this supporting construction, and structure was owing to supported not in place or can't discharge and the damage of follow-up operation causes the example of interruption of service hidden danger often to take place temporarily in the past.So the design of the stator shunt leads sliding support pin assembly of one-piece type non salient pole generator is suggested; This structure must solve the contradiction of the firm degree of high-rating generator stator end fixed support and the structural stress that causes of the operation temperature difference, and the necessary stress that rolling brought causes colligation to become flexible problem in the manufacture process.Structure must be succinct reliable; Initial condition in the time of must reverting to initial production fixedly the time once more; Make stationary state simple, will lose one-piece type non salient pole generator advantage quick for installation otherwise carry out the complex conversion operation again after the power plant with the switch process that discharges shape.

Embodiment:
As shown in Figure 1; The present invention is a kind of one-piece type non salient pole generator; By segmental machining assembly welding structure generator outer frame 1 is basic bearing frame, pedestal bearing 2 is installed is supported generator amature 3, by alternator shaft shaft coupling end latch-up structure 4, alternator shaft excitation end latch-up structure 5 stationary power generation machine rotors 3; What tooth inserted tooth structure dynamic panel bassinet structure 6 was installed in generator amature 3 encourages the end spindle nose, and generator unit stator shunt leads sliding support pin assembly 7 is installed on the generator outer frame 1.
As shown in Figure 2; By vapour end lower support 8 and stage casing lower support 9, encourage end lower support 10 machining finish respectively after again the order assembly welding connect and compose second support; Second upper part of the frame is connected the fixing generator outer frame 1 of forming with first support 11, vapour end lower support 8 is installed pedestal bearing 2 with encouraging on the end lower support 10.Vapour end lower support 8 stage casing lower supports 9 are distinguished machining earlier after encouraging end lower support 10 welding fabrications, and machined surface all is an outer surface, can utilize conventional machine tool to carry out machining.If adopt overall structure then because machined surface and must the custom-made process equipment in existing.Assembly welding forms second support after the machining; Form the generator outer frame with first support 11 again, vapour end lower support 8 forms the pedestal bearing installation site with encouraging end lower support 10, has satisfied integral form generator Structure demand; Make the generator of using this structure omit underframe than conventional structure; Material saving reduces cost, and mechanism's compactness is in light weight, convenient transportation.
The installation requirements that string is moving when preventing generator amature 3 transportation after causing the generator damage and arriving power plant, the fixture of having formed jointly rotor 3 by alternator shaft shaft coupling end latch-up structure 4 and alternator shaft excitation end latch-up structure 5.
Alternator shaft shaft coupling end latch-up structure 4 is like Fig. 3 and shown in Figure 4; By the lower plate 13 that is fixed on pedestal bearing 2 end faces, train wheel bridge 14 clamping alternator shaft shaft coupling end-journals 17; Alternator shaft is implemented radially to fix, prevent its vibration, it is fixing that bolt 16 passes the pin-and-hole and the lower plate 13 of non-salient pole alternator rotating shaft shaft coupling 17; Alternator shaft is implemented axial restraint; Prevent to go here and there damage, keep the axially normal relative position of generator amature 3 with generator pedestal bearing 2, the electric power supply plant unit is installed and used.
Alternator shaft excitation end latch-up structure is as shown in Figure 5, by the lower plate 18 that is fixed on pedestal bearing 2 end faces, train wheel bridge 19 clamping alternator shaft excitation end-journals 20.
The fixture structure of being made up of jointly alternator shaft shaft coupling end latch-up structure 4 and alternator shaft excitation end latch-up structure 5 to rotor 3 is simple, reliable for effect, is convenient to install and disassemble; Disassemble process and also needn't disassemble other parts of generator; Utilized generator to be positioned near the alternator shaft of pedestal bearing end face, be the most succinct locking scheme reliably, and be designed to thin-slab structure as ' locked ' zone; Can be held by the confined space, holding power also can satisfy instructions for use.Need disassemble other structure of generator and construct or support hypodynamic problem if adopt other position or structure then can produce.
As shown in Figure 7, generator amature 3 end faces are connected with triangular tooth jaw clutch clutch plate 21, and triangular tooth jaw clutch driving disc spacing pressing 22 is by pneumatic actuator 23 controls; The position of travel switch 24 monitoring triangular tooth jaw clutch driving disc spacing pressings 22; The output signal is transferred to pneumatic actuator 23, when alternator shaft 3 is in by the state of drive, is the forward drive state; This moment, triangular tooth jaw clutch driving disc spacing pressing 22 contacted for facing directly with clutch plate 21, can the normal delivery moment of torsion; When the increase of prime mover power output raises the alternator shaft rotating speed, generator changes 3 will drive the barring structure rotation, be reverse drive state; This moment triangular tooth jaw clutch driving disc spacing pressing 22 with clutch plate 21 for the inclined-plane contacts, in transfer torque, can produce an axial thrust; Force driving disc spacing pressing 22 to move to detaching direction; Promote travel switch 24 and produce separation signal, drive driving disc spacing pressing 22 by pneumatic actuator 23 and retreat, realize reverse automatic disengaging defencive function.Adopt jaw clutch to adopt other engagement flute profile to have the little advantage of diameter, can reduce the windmill loss and the noise of the clutch plate 21 that is installed on the rotor 3.
As shown in Figure 8, be shunt leads sliding support pin assembly stationary state at this moment, the pin end of supporting pin 25 cooperates with generator unit stator shunt leads support 26 holes; The taper pin end of supporting pin 25 cooperates with electricity generator stator stand end plate 27 holes; Be fixed on the electricity generator stator stand end plate 27 with bolt 28, this moment, the taper pin end of supporting pin 25 inserted shunt leads support 26 holes fully, and the big footpath of taper pin produces radial fit; Play the radial constraint effect; The pin end of supporting pin 25 can move axially in the hole of generator unit stator shunt leads support 26, has realized the effect that required radial support axially moves freely, and makes generator possess the peaking operation requirement.
Must be in stationary state in the stator shunt leads assembling process of generator, otherwise the stator shunt leads of generator can't install correctly, the binding strap of epoxy resin-impregnated also can't solidify in accurate forming.
In the operation after the stator shunt leads installs, the operation of also will rolling of the stator of generator is transported to power plant at last; Determine by the electric generator structure characteristics; This section is in the period, and shunt leads can produce radially relative displacement with the electricity generator stator stand end plate, if this device is not to be in release condition; Then the radial rigidity assembly structure of the binding strap of generator unit stator shunt leads, shunt leads support, epoxy resin-impregnated and supporting pin formation can retrain this relative displacement; The result produces very big structural stress, and the binding strap of the epoxy resin-impregnated of assembly structure is relaxed, and causes solid failure.So must interim realization release condition.As shown in Figure 9, be shunt leads sliding support pin assembly release condition at this moment, only need to remove bolt 28 this moment; To the moving segment distance of guest performer, the big footpath of taper pin end of supporting pin 25 loses mating reaction with the hole of support end plate 27, produces bigger radial clearance with supporting pin 25; Release condition have been realized; Be in this state in production process and in the transportation, promptly lose the radial constraint effect, avoid vibration force to pass through this supporting construction and damage the stator winding shunt leads.
When stator is transported to the power generator general assembly; To revert to stationary state by the tangential relative position that radially reaches of initial loading timing; State as shown in Figure 8; This moment, the taper pin end of supporting pin 25 was brought into play effect, when the taper pin end does not insert the hole of support end plate 27 fully, owing to exist the gap to insert easily; If this taper pin end is become and the close-fitting straight pin in the hole of support end plate 27, will produce because slight variation of relative position and can't to insert or insert drag excessive and can't recover the problem of stationary state.Because the taper pin end can close the hole that progressively gets into support end plate 27 in the process at the handle of bolt; The positive power of taper pin end guiding rule that the handle of bolt closes generation is very big; Even transportation causes significantly relative displacement, also can realize reverting to stationary state by the tangential relative position that radially reaches of initial loading timing.
Shunt leads sliding support pin assembly has solved the contradiction of the structural stress that high-rating generator stator end fixed support firm degree and the operation temperature difference cause, and the necessary stress that rolling brought causes colligation to become flexible problem in the manufacture process.Structure is ingenious, makes stationary state simple and reliable with the switch process that discharges shape.
Each technical scheme rational Match of the present invention has formed feasible overall structure; Can satisfy the primary demand of generator, reach required specification requirement, make generator operation reliable; The restrictive condition that overall dimension is compact, total weight gently satisfies transportation; And reasonable with prime mover matching structure, be convenient to power plant's civil Engineering Design, quick for installation reliable.
