Go out 1 end that V4 is connected to the 11st contactor SK11,3 ends of the 11st contactor SK11 are connected to the one of the 14th resistance R14
End, 4 ends of the 11st contactor SK11 are connected to the V phases of motor motor4, and the output W2 of the second inverter (8) is connected to the 9th
3 ends at 1 end of contactor SK9, the 9th contactor SK9 are connected to one end of the tenth resistance R10, and 4 ends of the 9th contactor SK9 connect
It is connected to the W phases of motor motor3, the output W2 of the second inverter (8) is also connected to 1 end of the 12nd contactor SK12, and the 12nd
3 ends of contactor SK12 are connected to one end of the 15th resistance R15, and 4 ends of the 12nd contactor SK12 are connected to motor
The W phases of motor4, the tenth resistance R10, eleventh resistor R11 are connected with the other end of twelfth resistor R12, thirteenth resistor
The other end of R13, the 14th resistance R14 and the 15th resistance R15 are connected, and when 4 motor normal operations, all contactors close
To terminal 1, the at this moment output of inverter is connected to the motor, the normal dragging motor operation of current transformer；It is dragged when railcar is in
When dynamic state, the influence in order to avoid the dragged power generation of permanent magnet synchronous motor to current transformer, all contactors are closed to terminal 2,
It is separated with current transformer, plays the role of protecting current transformer；It breaks down when in permanent magnet synchronous motor operation, if the too fast mistake of rotating speed
Control, at this moment generates larger back-emf voltage, and at this moment all contactors are closed to terminal 3, and the kinetic energy of train is disappeared on resistance
It consumes, and can comparatively fast stop；When 1 electrical fault controlled in one group of inverter or only needing to rotate a motor, even
The contactor for connecing inoperative motor is closed to terminal 2, while the phase bridge arm that two motors share also just sends out pulse mode from five bridge arms
It frees, another motor operation is controlled with the control mode of three bridge arm single motors.
