Description of the embodiments
The utility model will be further described with reference to the drawings and examples.
Examples
As shown in fig. 1, a capacitor charging pulse power supply based on a mechanically modulated induction motor of the present utility model includes: the device comprises a prime motor, a mechanical magnetic induction motor, a rectifier bridge, a charging controller, an energy storage capacitor, a pulse discharging switch and a pulse load; the prime motor drives the mechanical magnetic induction motor to rotate, and three-phase alternating current emitted by the mechanical magnetic induction motor charges the energy storage capacitor through the rectifier bridge; after the charging is finished, the energy storage capacitor discharges the pulse load through a discharge switch; and the charging controller regulates the magnetic field of the mechanically-regulated induction motor according to the received voltage detection signal of the energy storage capacitor, so as to realize the charging and discharging of the pulse power supply.
As shown in fig. 2, the mechanical magnetic regulating induction motor comprises a salient pole rotor 1, a magnetic conductive shell 2, a stator iron core 3, a stator armature winding 4, a permanent magnet 5, an end cover 6, a magnetic regulating ring 7 and a magnetic regulating ring translation executing device 8; a set of stator armature windings 4 are arranged on the stator core 3; the salient pole rotor 1 comprises a left half part 1-1 and a right half part 1-2, and is formed by processing alloy steel materials; the permanent magnet 5 and the magnetic regulating ring 7 are of annular structures and are arranged on one side of the stator and are coaxially arranged with the rotor, wherein the permanent magnet 5 is positioned in the middle of the two sections of magnetic conducting shells 2; the magnetic regulating ring 7 is positioned on the outer side of the permanent magnet 5, the axial position of the magnetic regulating ring can be moved randomly, when the magnetic regulating ring 7 is positioned at the short circuit position of the permanent magnet 5, the motor air-gap magnetic field is small, and when the magnetic regulating ring 7 is far away from the permanent magnet 5, the magnetomotive force of the permanent magnet 5 is not influenced by the magnetic regulating ring, and the motor air-gap magnetic field is large.
The magnetic adjusting ring 7 is connected with the magnetic adjusting ring translation executing device 8, and the charging controller drives the magnetic adjusting ring to move along the axial position by controlling the movement of the magnetic adjusting ring translation executing device 8. The magnetic adjusting ring translation executing device 8 comprises a motor and a screw rod connected with an output shaft of the motor, wherein the screw rod is connected with the magnetic adjusting ring and pushes the magnetic adjusting ring to axially move, and the motor is connected with the charging controller. By adopting the structure, the mechanical magnetic regulating induction motor can adopt other mechanical magnetic regulating modes, such as radial outward movement of a permanent magnet, and the like.
The working flow of the power supply system is as follows:
1) The magnetic modulation ring translation executing device 8 moves the magnetic modulation ring 7 to a position of magnetomotive force short circuit of the permanent magnet 5, the permanent magnet 5 is completely covered by the magnetic modulation ring 7 at the moment, and the rotor of the mechanical magnetic modulation induction motor is dragged to the highest working rotating speed through the prime motor;
2) The charging controller controls the magnetic modulation ring translation executing device 8 to move the magnetic modulation ring 7 to a position far away from the permanent magnet 5; then, three-phase alternating current emitted by the mechanical magnetic induction regulating motor charges an energy storage capacitor load through a rectifier bridge, and after the load is charged to a preset value, a charging controller receives a voltage detection signal of the energy storage capacitor, so that the rectifier bridge is disconnected;
3) The charging controller controls the magnetic modulation ring translation executing device 8 to move the magnetic modulation ring 7 to the position of magnetomotive force short circuit of the permanent magnet 5; simultaneously, the pulse discharging switch can be opened, and the energy storage capacitor can discharge the pulse load instantaneously.
In order to verify the effect of the capacitor charging pulse power supply based on the mechanical magnetic induction motor, a finite element model is built, electromagnetic simulation calculation is carried out, and an air gap flux density curve of the motor is shown in figure 3. It can be seen that when the magnetic flux adjusting ring 7 is at the short circuit position, the air gap flux density of the motor is far smaller than that when the magnetic flux adjusting ring 7 is far away from the permanent magnet 5 (the open circuit position), so that no-load iron loss is small at this time. Because of no exciting winding, the exciting magnetic field of the motor can be quickly established, and the motor magnetic field can quickly respond to the change of the exciting magnetic field along with the movement of the magnetic adjusting ring. Therefore, the capacitor charging pulse power supply based on the mechanical magnetic induction motor has the advantages of no excitation loss, simple system control and rapid establishment of an excitation magnetic field, and is suitable for being applied to a high-voltage high-current high-pulse power supply system.
The foregoing is merely a specific embodiment of the utility model, it being noted that: it will be apparent to those skilled in the art that simple modifications, equivalent variations or modifications can be made without departing from the technical solution of the present utility model, all falling within the scope of the utility model.
