Apply for a part of the embodiment, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall in the protection scope of this application.
Referring to Figure 1, Fig. 2 and Fig. 3, Fig. 1 are one of the synchronous capacitor rotor in one embodiment provided by the present application
The structural schematic diagram of a rotor unit, Fig. 2 are that the structure of the synchronous capacitor rotor in one embodiment provided by the present application is shown
It is intended to, Fig. 3 is the cross-sectional view of synchronous capacitor rotor shown in Fig. 2.
The excitation part of synchronous capacitor is provided by the embodiments of the present application mainly in excitation winding 13 and the iron core of rotor
Rotor unit can be understood as the rotor of a shortening, equally have iron core and excitation winding 13,
Iron core generally includes iron core main body 11 and multiple magnetic poles 12, and iron core main body 11 can be polygonized structure, specifically,
Joined together by it should have with the quantity of magnetic pole 12, the quantity of magnetic pole 12 can be different according to different requirements, such as the number of magnetic pole 12
When amount is four, iron core main body 11 can be regular quadrangle, and four of iron core main body 11 can be symmetrically arranged in magnetic pole 12 at this time
On side, and when 12 quantity of magnetic pole is six, iron core main body 11 can be regular hexagon, and six magnetic poles 12 can symmetrically be arranged in
On six sides of iron core main body 11.
It can be integrally formed structure between iron core main body 11 and multiple magnetic poles 12, it is of course also possible to be separated two
Part, at this point, between magnetic pole 12 and iron core main body 11 connection can be cooperatively formed by fixing.It can be arranged in the one of the two
Groove body, another setting and the matched bulge-structure of groove body are caught in bulge-structure in matched groove body and form fixing in connection
Cooperation, when specific implementation, dovetail groove or T-slot is can be set into groove body, so as to form better position after being caught in
Fixed function.
Specifically, the magnetic pole 12 and iron core main body 11 of rotor can be pressed using folded silicon steel slice, screw rod can also be passed through
It is pressed, silicon steel sheet can also be replaced using the good material of other magnetic conductivity, such as ferrocobalt etc..
Magnetic pole 12 generally includes pole shoe and polar cap two parts, and excitation winding 13 can specifically be wound on the pole shoe portion of magnetic pole 12
Point, circumferential position limiting structure of the polar cap part as excitation winding 13, plays the role of guiding magnetic field diverging at this time.
Shaft part 14, namely the both direction in a rotor unit axis can be set in the axial ends of iron core main body 11
On a shaft part 14 is respectively set, can directly by screw shaft part 14 be connect with iron core main body 11 it is integral, can also
It is attached so that card slot is arranged, specific connection type is there are also very much, as long as shaft part 14 can be made to be fixed on iron core main body 11
Axis on, be suitable for technical solution provided by the present application.
Shaft part 14 can be understood as the shaft of segment, setting at rotor unit both ends, so as to other rotors
Unit is attached, specifically, can be attached by shaft coupling component between rotor unit.
Above-mentioned synchronous capacitor rotor be equivalent to by elongated rotor originally with the shorter rotor unit of multistage connect into
Row substitution, multiple rotor units connect to form elongated rotor entirety, on the basis of meeting centrifugation force request, rotor unit
Fabrication of iron core is simple more many than the fabrication of iron core of original rotor elongate integral, so that the cost of manufacture of entire rotor be made to drop significantly
It is low, also, be attached between rotor unit by shaft coupling component, it is equivalent to the shaft that the long shaft multistage of script is shorter
The connection of part 14 is substituted, and the weight of rotor is distributed in multiple short shafts, improves stress condition, it is whole to improve shaft
The service life of body.
It, can be in each rotor list in order to which the whole stress in structure of the rotor for connecting into multiple rotor units is more preferable
It is socketed pivot flange 21 on the shaft part 14 of member, bearing 22 can be set between pivot flange 21 and shaft part 14, so as to
It is supported pivot flange 21 to rotor in the case where not influencing rotor rotation, improves the stress condition of shaft part 14, from
And whole rotor is made to have stronger rigidity in the axial direction.
Specifically, cylinder step structure can be set on two axial shaft parts 14 of iron core main body 11, so as to
It is socketed in bearing 22 on shaft part 14, is bonded with the cylindrical lateral surface of cylinder step structure on shaft part 14, pivot flange 21 can
To be further socketed on bearings 22, to provide support to shaft part 14.
Excitation winding 13 needs field power supply supply of electrical energy, in specific wiring, since excitation winding 13 at work can
As shaft rotates, the electric power incoming line connecting with field power supply can also be driven to rotate, at this point it is possible in the axis of rotor unit
Hollow shaft structure 31 is set on line, then the hollow shaft segment that the power supply line of excitation winding 13 can use hollow shaft structure 31 carries out
Arrangement, since power supply line is distributed at axis, excitation winding 13 can be avoided to rotate bring to the greatest extent to be influenced, so that wiring
It is more reasonable.
It should be noted that hollow shaft structure 31 is not necessarily referring to have an axis through its entirety inside rotor unit, and
It is the hollow space for having a shaft-like at the axis of rotor unit, specifically, the hollow space is by 14 (iron core of first rotating shaft part
11 side of main body), the hollow space structure on the axis of iron core main body 11 and the second shaft part 14 (11 other side of iron core main body)
At the shaft-like that can be respectively set in first rotating shaft part 14, iron core main body 11 and the second shaft part 14 on axis is empty
Between, three hollow shaft-like spaces form the space structure of a hollow shaft structure 31.
Excitation winding 13 can use traditional good conductor such as copper or aluminium, but in order to have better field performance, this reality
The excitation winding 13 for applying rotor unit in example can be superconductor, turn to superconduction winding by superconductor as excitation
Winding 13.
It should be understood that the connection between rotor unit is really the connection of shaft part 14 between rotor unit, shaft part
Connection between 14 can realize by shaft coupling component, and there are many shaft coupling components, such as diaphragm coupling 24, spring column pin shaft coupling
Device 24 etc., and in the synchronous capacitor rotor provided in the present embodiment, it can be arranged on the shaft part 14 of a rotor unit
Keyway, makes to be caught in keyway with the matched key 23 of keyway and forms flange, then will be between two rotating shaft units by shaft coupling 24
Shaft part 14 connects, and transmits the torque between two rotor units by shaft coupling 24, so that multiple rotor units are formed one
Whole rotor.
In order to keep the connection between rotor unit more compact, torque transmitting is even more ideal, and just awake shaft coupling 24 can be used.
The above are the synchronous capacitor rotor in one embodiment provided by the present application, the rotor is by original elongate integral
Rotor segment is at multiple rotor units, to reduce the manufacture difficulty of rotor core, greatly reduces the cost of production, excitation
Also from originally, coiling became the coiling on the iron core of shorter rotor unit on the iron core of elongate integral for the coiling of winding 13, because
The online and assembling of this excitation winding 13 is relatively originally conveniently very much；The rotor of segmented also greatly reduces in weight, right
For shaft part 14, weight bearing situation improves significantly, and the service life of shaft is integrally improved；Meanwhile each rotor unit it
Between be provided with pivot flange 21, pivot flange 21 to shaft part 14 formed support, ensure that axial rigidity, improve shaft part
Stress condition between 14.
