Description
Technical field
The utility model relates to a kind of double-fed wind power generator rotor structures, and in particular to a kind of doubly-fed wind turbine turn
The leading-out wire structure of subconductivity row belongs to new energy and energy conservation/renewable and clean energy resource/energy and wind energy integrative and utilizes technical field.
Background technique
In wind-power electricity generation, generator is the core equipment of wind power generation plant, and the rotor of generator rises in power generation process
To important function, and lead-out wire is one of the important component that generator amature three-phase current is led to frequency converter.Generator operation
When, rotor busbar will be by the comprehensive functions power such as centrifugal force, electromagnetic force and thermal stress, therefore rotor busbar structure is reliable
Property it is more demanding, improve busbar reliability of structure demand it is especially urgent.
Rotor leading-out wire structure has following two schemes at present:
Scheme one: busbar uses material for the copper busbar of TMR, by cold pressing bending and torsion technological forming.Busbar
One end and rotor coil weld, and the other end and rotor silicone rubber for cable weld.Busbar and rotor coil and silicone rubber for cable weld
Fig. 1 is seen in shaft with no latitude band binding and fixing after connecing.
Scheme two: busbar uses material for the copper busbar of TMR, by cold pressing bending and torsion technological forming.Busbar
One end and rotor coil weld, and the other end is bolted connection with rotor silicone rubber for cable.Busbar and rotor coil and silicon
It is fixed in shaft after rubber cable welding with insulation pressing, sees Fig. 2.
In above two scheme, copper busbar is required by cold pressing bending and is reversed, convenient and silicone rubber for cable company
It connects, but busbar is easy to produce craftsmanship damage at the time of molding and there are residual stress.In the presence of damage and residual stress
Busbar can generate stress concentration, cause busbar that fatigue occurs under the comprehensive functions power such as centrifugal force, electromagnetic force and thermal stress
Damage eventually leads to busbar fusing scaling loss, can also affect on the dynamic balancing of rotor to a certain extent.
Utility model content
Purpose of utility model: the purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of double-fed wind-force
The leading-out wire structure of generator amature busbar, is not necessarily to bending and twisting formation, and connective stability greatly enhances.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this:
A kind of leading-out wire structure of double-fed wind power generator rotor busbar, including it is rotor coil, cable, shaft, affixed
The line conductor row of rotor coil and cable, which is characterized in that the line conductor row and cable head are on same straight line, the conducting wire
Row is arranged right below insulation pressing, the insulation pressing and cable face contact, and the insulation pressing and shaft are affixed.Busbar shape
Shape can be the shapes such as cylindrical body or cuboid, and the matching of dimension can be carried out according to cable thickness and space, compared to
Sheet outskirt, internal existing participation stress very little, will not generate stress concentration, cause busbar that fatigue damage occurs, most
The phenomenon that leading to busbar fusing scaling loss eventually.
Further, Rotor carriage, the Rotor carriage and shaft face are equipped between the insulation pressing and shaft
Contact, the Rotor carriage and insulation pressing are affixed.Using interference fit, when rotation, is relatively solid for Rotor carriage and shaft
Calmly, support frame and insulation pressing threaded connection or snapping keep the device formation one of fixed busbar and cable relatively stable
Frame, situations such as shake will not be sent during rotor runs at high speed, stability greatly enhances.The Rotor carriage
Material and insulation pressing can be ceramics, silicon nitride or other non-metallic insulation materials, the insulating properties of ceramics and silicon nitride and
It is anti-wear good, long service life.
Further, the insulation pressing side offers cable through-hole, and insulation pressing axial direction one end offers threaded hole,
The threaded hole and cable through-hole are interconnected.Cable passes through through-hole, and bolt is screwed into threaded hole, and the head of bolt is tightly pushed down
Cable, has haved the function that fixed cable, while cable head and busbar be by being welded and fixed, by the fixation of the two o'clock,
Ensure that cable will not send violent shaking during rotor high speed rotation, stability greatly enhances.
Further, the Rotor carriage and shaft are interference fitted.It is fixed compared to flat key, the fixed form of interference fit
Make support frame uniform force, moreover during rotor operation, shaft temperature can obtain certain raising, original of expanding with heat and contract with cold
Reason, further increase magnitude of interference, and then Rotor carriage fixed in shaft it is stronger.
Further, the busbar uses material for the copper busbar of TMR.There is crimping at the both ends that TMR is used as bus
The soft litzendraht wire of multiply, compared to TBR copper strap wire have many advantages, such as resistivity it is low, can bending degree it is big.
The utility model has the advantages that the utility model has the advantage that compared with traditional sight technology
1. busbar structure is simple, bending and torsion technique are not needed, busbar can effectively be avoided to generate craftsmanship damage
The risk of wound；
2. busbar and silicone rubber for cable use welding procedure, firm and reliable connection；
3. silicone rubber for cable is fixed on rotor support plate using insulation pressing, cable can be fixed effectively.
