As shown in fig. 1-3, the invention provides an induction power supply test stand 1000, which can realize test research on non-contact power supply of a train and provide guidance for the non-contact power supply of the train.
Specifically, the inductively powered test stand 1000 includes a peripheral housing 100, a rotating shaft 200, and a turntable 300, where the peripheral housing 100 includes a bottom wall 101 and a peripheral circular wall 102, and the peripheral circular wall 102 is fixed to the bottom wall 101, i.e., the bottom wall 101 provides support for the peripheral circular wall 102. The bottom wall 101 may be a rectangular plate, a circular plate, or the like, and the specific shape is not limited. The peripheral circular wall 102 is cylindrical and fixed to the bottom wall 101. Of course, it will be appreciated that a top cover may be mounted on top of the peripheral wall 102 to enclose the peripheral wall 102.
The inner wall of the peripheral circular wall 102 is provided with two layers of first mounting positions for mounting the coil 700 or the permanent magnet 600 along the axial direction of the peripheral circular wall 102. Specifically, each layer of first mounting positions are uniformly distributed inside the peripheral circular wall 102 along the circumferential direction of the peripheral circular wall 102.
The rotating shaft 200 is disposed in the peripheral circular wall 102, and the rotating shaft 200 is rotatably connected with the bottom wall 101 and coaxially disposed with the peripheral circular wall 102.
The number of the turntables 300 is 2, the turntables 300 are fixed on the rotating shaft 200 along the axial direction of the rotating shaft 200 at a preset distance, and correspond to two layers of installation positions on the peripheral circular wall 102 respectively, and the turntables 300 are provided with second installation positions for installing the coils 700 or the permanent magnets 600. Specifically, the mounting positions of the 2 turntables 300 along the rotation shaft 200 are identical to the height of the 2-layer first mounting position on the peripheral circular wall 102.
The inductive power supply test stand 1000 provided by the invention has an upper coaxial rotating mechanism and a lower coaxial rotating mechanism in common: 2 turntables 300. One layer of rotation mechanism is an induction power supply layer 400 and is responsible for simulating the generation process of induced electromotive force, and the rotating disc 300 of the induction power supply layer 400 and the inner side of the peripheral round edge can be selectively provided with devices such as a collector coil, a suspension coil, a permanent magnet 600 and the like according to test requirements. The other layer of rotating mechanism is a driving layer 500, which is used for simulating the work of an asynchronous motor or a synchronous motor, and can be configured into a squirrel-cage asynchronous motor, a squirrel-cage permanent magnet 600 synchronous motor or a squirrel-cage excitation synchronous motor according to specific experimental contents.
When the induction power supply test stand 1000 provided by the invention is used, corresponding permanent magnets or corresponding coils 700 (current collecting coils, levitation coils and the like) are respectively arranged at two layers of first installation positions of the peripheral circular wall 102 and at the second installation positions of the 2 turntables 300 according to data required to be measured so as to simulate the running speed of a magnetic levitation train and the condition of collecting induction power supply, namely the invention realizes the test research on non-contact power supply of the train and provides guidance for the magnetic levitation train.
The linear motor structure of an actual magnetic levitation train is composed of a propulsion coil 700 mounted on the ground end, a coil 700 (superconducting coil or normal exciting coil) to which direct current is applied on the train, and a power conversion device. When three-phase alternating voltage is applied to the propulsion coil 700, the propulsion coil 700 can generate a traveling wave magnetic field moving at a high speed, and the magnetic field acts with a magnetic field generated by the superconducting coil (or the exciting coil) to generate thrust on a train body, so that the train is driven to move.
The linear motor is originally evolved from a rotary motor and is obtained by unfolding a stator and a rotor; the stator portion is generally considered to be the primary and the rotor portion is the secondary. Considering that the space occupied by the induction power supply test stand 1000 is reduced, and the running characteristic of the linear motor is reflected as much as possible, the induction power supply test stand 1000 adopts a rotary motor to equivalently use the linear motor structure in the maglev train.
Specifically, the present invention discloses the configuration of the driving layer 500 as follows: squirrel-cage asynchronous induction motor, squirrel-cage permanent magnet synchronous motor and squirrel-cage excitation synchronous motor.
When simulating a squirrel cage induction motor, as shown in fig. 4, a coil winding that is not energized is mounted on a second mounting position of the turntable 300 on the rotating shaft 200 near the bottom wall 101, specifically, the coil winding is detachably mounted on the second mounting position by a screw or the like, so that other coils 700 or permanent magnets 600 or the like can be mounted when other experiments are performed.
The layer of the peripheral circular wall 102 near the bottom wall 101 is provided with a stator coil winding to which alternating current is supplied, specifically, the stator coil winding is detachably mounted on the first mounting position by a screw or the like, so that other coils 700 or permanent magnets 600 or the like can be mounted when other tests are performed.
For convenience of description, the first mounting position of the layer close to the bottom wall 101 is named as the lower layer of the peripheral circular wall 102, the first mounting position of the layer far from the bottom wall 101 is named as the upper layer of the peripheral circular wall 102, the turntable 300 close to the bottom wall 101 is named as the lower turntable 302, and the turntable 300 far from the bottom wall 101 is named as the upper turntable 301.
Alternating current is supplied to the stator coil windings inside the peripheral circular wall 102, and the stator coil windings generate a rotating magnetic field corresponding to the travelling wave magnetic field of high-speed motion in the actual maglev train system. Meanwhile, the coil windings of the lower turntable 302 cut the rotating magnetic field to generate induced electromotive force, thereby generating current and interacting with the rotating magnetic field to form rotating torque, so as to drive the lower turntable 302 to rotate at a rotating speed lower than that of the rotating magnetic field. The test platform works in a squirrel-cage asynchronous induction motor mode and can equivalently simulate the operation of an asynchronous linear motor.
When simulating a squirrel cage permanent magnet synchronous motor, as shown in fig. 5, a permanent magnet 600 is mounted on a second mounting position of the turntable 300 on the rotating shaft 200 near the bottom wall 101, and a stator coil winding to which alternating current is applied is mounted on a first mounting position of the layer of the peripheral circular wall 102 near the bottom wall 101.
Alternating current is supplied to the stator coil windings inside the peripheral circular wall 102, and the stator coil windings generate a rotating magnetic field corresponding to the travelling wave magnetic field of high-speed motion in the actual maglev train system. At the same time, the rotating magnetic field generated by the stator coil windings interacts with the permanent magnets 600 on the lower turntable 302, generating a rotational torque that drives the lower turntable 302 to rotate at a synchronous speed. The scheme can simulate the operation of the linear synchronous motor of the simulated permanent magnet 600.
When the squirrel-cage excitation synchronous motor is simulated, as shown in fig. 6, a coil winding which is electrified with direct current is installed on a second installation position of the turntable 300, which is close to the bottom wall 101, on the rotating shaft 200, and a stator coil winding which is electrified with alternating current is installed on a first installation position of the layer, which is close to the bottom wall 101, on the peripheral circular wall 102.
Namely, the side wall of the lower turntable 302 is provided with a coil winding which is used for equivalent superconducting coils or exciting coils on the maglev train, and the coil winding is electrified with direct current to generate a magnetic field with constant size; the stator coil winding is arranged on the lower layer of the inner side of the peripheral circular wall 102 to form the squirrel-cage excitation synchronous motor. The rotating magnetic field generated by the stator coil windings reacts with the coil winding magnetic field on the lower turntable 302 to generate a rotating torque, which pushes the lower turntable 302 to rotate at a synchronous speed. The scheme can simulate the working characteristics of the excitation type linear synchronous motor.
In actual conditions, when the magnetic levitation train runs at a high speed, the levitation coils at the two sides of the track cut magnetic fields generated by the superconducting coils on the train to generate induced electromotive force and a changed magnetic field, and the collector coils on the train also cut the magnetic fields of the levitation coils at a high speed to generate dynamic electromotive force.
In some embodiments, the permanent magnet 600 and the collector coil are mounted on the rotating shaft 200 at the second mounting position of the turntable 300 far from the bottom wall 101, and the levitation coil is mounted on the first mounting position of the peripheral circular wall 102 far from the bottom wall 101, as shown in fig. 7.
In operation, the upper turntable 301 corresponding to the inductive power supply layer 400 rotates with the lower turntable 302, and the levitation coil of the peripheral circular wall 102 cuts the rotating magnetic field generated by the permanent magnet 600 to generate induced electromotive force and current, thereby generating a variable magnetic field. While the collector coils on the upper turntable 301 cut the magnetic field of the levitation coils, thereby generating induced electromotive force. The electromotive force variation of the collector coil when different currents are applied to the superconducting coil can be evaluated by replacing different permanent magnets 600.
In other embodiments, the levitation coil is mounted on the spindle 200 at a second mounting location of the turntable 300 away from the bottom wall 101, and the permanent magnet 600 and the collector coil are mounted on the peripheral circular wall 102 at a first mounting location of the layer away from the bottom wall 101, as shown in fig. 8.
When the levitation coil rotates with the upper turntable 301, the levitation coil cuts the magnetic field of the permanent magnet 600 to generate a rotating magnetic field. The collector coil on the peripheral circular wall 102 cuts the rotating magnetic field to generate induced electromotive force. The scheme can simulate the change condition that the electromotive force of the collector coil changes along with the current of the superconducting coil.
According to the invention, alternating current is supplied to the stator coil winding at the lower layer inside the peripheral circular wall 102 to push the lower turntable 302 corresponding to the driving layer 500 to rotate and drive the upper turntable 301 of the induction power supply layer 400 coaxial with the lower turntable, and the process simulates the linear motor driving part of the magnetic levitation train; the upper turntable 301 corresponding to the induction power supply layer 400 generates induced electromotive force in the collector coil in the induction power supply layer 400 in the rotation process, and the process represents the induction power supply process of the maglev train in high-speed operation. By equivalent linear motor into rotary motor, a lot of space is saved, and the driving and induction power supply process of the maglev train under high-speed operation is truly simulated.
In some embodiments, the invention specifically discloses that the bottom wall 101 is integrally connected with the peripheral circular wall 102. The bottom wall 101 and the peripheral circular wall 102 are not limited to being integrally connected, and may be welded or detachably connected.

The first arcuate wall and the second arcuate wall can form a complete cylindrical wall.
The outer circular wall 102 is arranged in a mode that the first arc-shaped wall and the second arc-shaped wall can be opened and closed, so that the coil 700 or the permanent magnet 600 on the first installation position and the second installation position can be conveniently assembled and disassembled.
Further, the invention specifically discloses that the other side of the second arc-shaped wall is clamped with the other side of the first arc-shaped wall. It should be noted that, the outer walls of the first arc wall and the second arc wall may be provided with mounting blocks, through holes or threaded holes allowing the bolts to pass through are formed in the mounting blocks, and connection is achieved through the bolts.
