Abstract
Disclosed is a double-layer-winding motor generator with three three-phase and four-pole parallel loops, wherein, each four-turn coil of one parallel loop is respectively wound around poles P3 and P4 and is in parallel connection with a cross wire; the six-turn coils and the two-turn coils of one parallel loop are wound respectively around poles P2 and P3 and are in parallel connection with a cross wire; the six-turn coils and the two-turn coils of one parallel loop are wound respectively around poles P1 and P4 and are in parallel connection with a cross wire. Due to the decrease of the overlap of the cross wires for connecting all poles, the axial length of the motor generator is reduced. Partial overheat can be restrained by reducing the circulating current of the three parallel loops, so that the utilization efficiency of the power supply can be improved.
Description
The present invention relates to a kind of armature winding syndeton of motor generator, more particularly, relate to a kind of armature winding syndeton that is used for three-phase 4 utmost points 3 shunt circuit two layer winding motor generators.
Motor generator comprises a stator and a rotor, and for example when a synchronous motor was used for 50 hertz frequency and has 4 electrode structures, rotating speed was 1500 rev/mins.Stator core is made up of composite wafer, is provided with a lot of grooves in the inner periphery side of stator, is wound with armature winding in the groove.In a generator, the waveform of induced voltage is preferably desirable sine wave.For this reason, need make the magnetic flux distribution in air gap is sinusoidal waveform.When armature winding was pressed the form formation of concentric winding, the distribution of magnetic flux density becomes square waveform, and was different fully with sinusoidal waveform.Therefore, armature winding adopts distributed winding.
When the coil side electrical degree of coil separated 180 °, this winding was called whole apart from winding.When the coil side electrical degree of coil separated less than 180 °, this winding was called fractional-pitch winding.In order to make magnetic flux distribution more near sinusoidal waveform, armature winding adopts fractional-pitch winding.Its reason is, if be three phase electric machine, usually the ratio β of coil span and pole pitch be taken as 5/6 and can reduce the high order harmonic component that is accounted for main component by 5 subharmonic and 7 subharmonic.
Under the situation of turbo generator, the most of generators that are used for old-fashioned cogeneration power plant are two plate motors, for most of generators of dual-purpose nuclear power station because the characteristic of their drive motor is 4 pole type motors.Usually, the armature winding of turbo generator is that Y connects, and the number of shunt circuit is the approximate number of its number of poles.If for example be one 4 utmost point motors, the shunt circuit number is 4,2 or 1.Reason is, when the shunt circuit number was the approximate number of number of poles, the voltage in the middle of can each loop of balance can dispose by identical mode on each shunt circuit is electric.
In order to improve generator capacity,, must improve the product of the voltage and current of generator because that its power factor is bordering on is constant.Though in the generator of low capacity, each coil series connection is so that obtain high voltage, in jumbo generator, because problems such as insulation, coil connects by 2 or 4 shunt circuits usually.
Yet, under some situation, can not be taken as the approximate number of number of poles owing to the reason shunt circuit number of capacity motor.Under such a case, the induced voltage imbalance in each shunt circuit, thereby stream has loop current between the shunt circuit.In order to address this problem, it is a kind of by changing each coil span in order to reduce the voltage magnitude between each shunt circuit and the unbalanced winding method of attachment of phase place that sequence number is that the Japan Patent open file of 54-6683 discloses.
The turbo generator that is used for nuclear power station is generally three-phase 4 utmost points 4 shunt circuit two layer winding formula motors, and has as the lead-in wire of crossing over hunting at steamer pusher side and these both sides of lead-in wire sleeve pipe side.Always have 12 lead-in wire sleeve pipes, 6 of every sides, and the terminal connection case also is configured in both sides.When the shunt circuit number was 3, lead-line configuration was in a side.Thereby 6 lead-in wire sleeve pipes only are configured in a side, and the terminal connection case also only is configured in a side.
Yet, when the shunt circuit number is 3, compares with 4 shunt circuit windings and some problem can occur.These problems are described below, and for instance, number of stator slots is 72.Because every extremely every phase groove is counted NSPP and can be utilized formula NSPP=(stator index/(number of phases * number of poles) obtains, NSPP=6 in this example.Thereby a utmost point is made up of 6 top winding and 6 bottom coil.
Because the coil number NPSC of each shunt circuit can utilize formula NPSC=(number of stator slots)/(number of phases * shunt circuit number), NSPC=6 in the example of 4 shunt circuit windings, NSPC=8 in the example of 3 shunt circuit windings.
Thereby, in the example of 4 shunt circuit windings, can constitute a utmost point by 1 shunt circuit.Yet in the example of 3 shunt circuit windings, shunt circuit is distributed in a plurality ofly extremely goes up, thereby needs to connect between each utmost point and cross over lead.Cross over that the hunting number is minimum and be 24 (in the example of 4 shunt circuit windings, this minimum add up to 12), and need length, the axial length of stator is increased owing to cross over lead surely along the axis direction stake.
In addition, if every coil in mutually is divided into 3 shunt circuits, because 3 relative magnetic poles in shunt circuit are in different electrical degrees position, making the phase place of the induced voltage in each shunt circuit is different with amplitude.Thereby, in the middle of each shunt circuit, produce loop current, cause local overheating and supplementary load loss.
Aspect the armature winding that is used for three-phase 4 utmost points 3 shunt circuit two layer winding formula motor generators, first purpose of the present invention provides a kind of armature winding syndeton that is used for motor generator, and purpose is the overlapping axial length that shortens motor generator by the leap lead of avoiding as far as possible connecting at each interpolar.
Second purpose of the present invention provides a kind of armature winding syndeton that is used for motor generator, wherein reduces to loop current minimum and that 3 shunt circuits of reduction are middle by the uneven ratio that makes the induced voltage in 3 shunt circuits and suppresses local overheating and supplementary load loss.
The 3rd purpose of the present invention provides a kind of armature winding syndeton that is used for motor generator, wherein can reduce and cross over number of lead wires and can make Voltage unbalance reduce to minimum.
It is to utilize the coil among 3 shunt circuit A, B, the C to form 4 utmost point P by providing a kind of that first purpose of the present invention can reach
