Abstract
The utility model relates to a wave winding of a brushless exciter. The wave winding comprises an armature coil of the brushless exciter, an end part connecting wire, an interelectrode connecting wire and a central ring. The brushless exciter adopts the wave winding to reduce connecting wires among coil groups. Braided wires of the armature coil are straightly placed in slots to facilitate welding a connecting wire at the end part. The central ring is placed below the armature coil, so as to bring convenience for the interelectrode connecting wire of the armature coil to be directly connected to the central ring, and facilitate interelectrode wiring.
Description
Technical field
The utility model relates to the wave winding of brushless exciter, relates in particular to the wave winding of the brushless exciter of supporting capacity 60MW and following turbo generator.
Background technology
Excitation system is one of synchronous generator chief component, and excitation system performance and reliability of operation directly have influence on power supply quality and the reliability of operation and the stability of generator.The turbo generator excitation system has three kinds at present: coaxial DC exciter excitation system, silicon-controlled static self-shunt excitation system and brushless excitation system.Brushless excitation system is the electric current by the armature generation of pivot-rotatable type AC exciter, supply generator rotor-exciting after the rotating rectifier rectification, brushless excitation system possess plurality of advantages such as reaction speed is fast, unit operation is safe and reliable, the working service workload is little.Current, at home and in the world, turbo generator has generally adopted brushless excitation system.
The armature winding of tradition brushless exciter adopts lap winding, shown in Fig. 1～3, comprises armature coil 6 and lead-out wire 7, any two adjacent coils all back one be stacked in previous above.When being short distance, the advantage of lap winding can save the end with copper be convenient to obtain more parallel branch, shortcoming be a motor last several coils rule comparatively the difficulty, connecting line between the coil groups is longer, and end wiring sometimes is very difficult, more quite takes copper at number of poles.
The utility model content
The purpose of this utility model is to overcome the weak point of existing brushless exciter lap winding, and a kind of wave winding of brushless exciter is provided, and reduces the connecting line between the coil groups, and the strand disposed upright of armature winding is placed in the groove, is convenient to the end wiring.
The technical solution of the utility model is as follows:
A kind of wave winding of brushless exciter comprises armature coil, end wiring, interpolar connecting line and the centering ring of brushless exciter; It is characterized in that: centering ring is placed in described armature coil below, and the strand of described armature coil directly is placed in the groove.
Useful technique effect of the present utility model is:
The armature coil of the utility model brushless exciter adopts wave winding, and wave winding can reduce the connecting line between the coil groups, and the strand of armature winding is directly to be placed in the groove, is convenient to the end wiring.Centering ring is placed in the armature coil below, and the lead wire of being convenient to armature coil is directly received on the centering ring, makes things convenient for the interpolar wiring.And the employing wave winding, be not easy to go wrong in the motor operation later stage, it is also convenient than lap winding to safeguard.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Shown in Fig. 4～8, the utility model comprises armature coil 1, end wiring 2, interpolar connecting line 3 and centering ring 4, and centering ring 4 is placed in armature coil 1 below, and the strand 5 of armature coil 1 directly is placed in the groove.Any two series coils advance like coiling direction wave in the wave winding of brushless exciter, and the order of connection between the lap winding coil of Fig. 1～3, and end shape difference, the connection rule of wave winding are all same polarity (N for example
1, N
2...) under belong to same group coil and be together in series successively by wave-like, form one group; Again all another polarity (S for example
1, S
2...) under belong to same group coil and be together in series successively by wave-like, form another group; At last these two groups of coils are connected into serial or parallel connection as required, constitute one group of winding.Among Fig. 5,6, the strand 5 of the levels coil of end wiring 2 is directly to be placed in the groove, makes things convenient for butt welding to connect.Among Fig. 7, interpolar connecting line 3 makes things convenient for interpolar to connect, and among Fig. 8, centering ring 4 connects the central point of every phase, saves wiring.Compare the lap winding of Fig. 1～3, the utility model can reduce the connecting line between the coil groups, reduces copper consumption, and is also more convenient in motor operation later maintenance, is not easy to go wrong.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
