Description
Technical Field
The invention relates to the technical field of magnetic suspension, in particular to a high-temperature superconducting magnetic suspension start-stop system.
Background
With the continuous progress of science and technology, the use requirements of high-speed magnetic suspension trains in social life are increasing day by day. From the perspective of a suspension mode, the Holloman test base of the US air force and the Japanese sorb line adopt an electric suspension mode, wherein the Japanese sorb line adopts a linear motor for propulsion and an 8-shaped induction coil for achieving the speed of 603 km/h.
Generally, high-speed electromagnetic levitation systems provide contactless driving force by using a long-stator linear induction motor, and although reverse braking can be performed by changing a through-current mode in a stator coil, other braking modes need to be added from the viewpoint of energy consumption and reliability. Besides the reverse connection braking, a row deceleration section is generally adopted to add an eddy current brake for magnetic eddy current braking. The principle of the braking mode is as follows: when the vehicle-mounted magnet passes through the eddy current induction plate, magnetic induction lines generated by the magnet are cut by metal in the metal induction plate to generate eddy current, so that an eddy current magnetic field with the magnetic pole opposite to that of the vehicle-mounted magnet is formed to brake the vehicle-mounted magnet. Because the metal induction plate has resistance, the strength of the formed eddy current has limitation, and the problem of induction plate heating caused by the formation of the eddy current causes problems in the manufacturing and design of the eddy current induction plate. Meanwhile, the magnetic suspension train adopting the electric suspension mode can suspend only when the train reaches a certain speed, and auxiliary equipment such as steel rails and the like still need to be laid at a starting section.

For example, as shown in fig. 2, the vehicle body may be partitioned in the running direction, and the braking area, the hovering area, the induction motor propulsion area, and the unpowered detection area may be sequentially partitioned among the conventional levitation propulsion areas. Wherein the braking area is a train deceleration area; the hovering area is an area when the train stops at the station; the propulsion area is a train auxiliary acceleration area; the unpowered detection area is a speed identification area when the train propulsion system is switched. Corresponding track beam side wall means may be provided on the track beam side walls for different areas and optionally track beam bottom means at the track beam bottom of part areas (hovering area and induction motor propulsion area as described below).
The vehicle-mounted power magnet 1 can be matched with a conventional suspension propulsion area track beam side wall device to carry out electromagnetic suspension propulsion.
The track beam bottom device is arranged at the bottom of the track beam corresponding to the track beam side wall provided with the hovering area track beam side wall device and the induction motor propulsion area track beam side wall device, and comprises a bottom superconducting bulk magnet 5 arranged corresponding to the vehicle-mounted hovering magnet 2 and a starting stator coil (a ground starting stator coil which can form an auxiliary acceleration induction motor system together with the vehicle-mounted induction unit) 6 arranged corresponding to the vehicle-mounted induction unit 3;
Namely, the track beam bottom device is arranged at the bottom of the track beam in the hovering area and the track beam in the induction motor propulsion area, and the starting stator coil and the superconducting bulk magnet are not arranged at the bottom of the track beam in other areas (the conventional levitation propulsion area, the braking area and the non-power supply detection area).
The conventional levitation propulsion area track beam side wall device, the induction motor propulsion area track beam side wall device and the unpowered detection area track beam side wall device comprise side wall induction units, the braking area track beam side wall device comprises high-temperature superconducting coil magnets and high-temperature superconducting block magnets, and the hovering area track beam side wall device comprises high-temperature superconducting block magnets.

In the invention, all the high-temperature superconducting bulk magnets meet the following requirements: the high-temperature superconducting magnet comprises a low-temperature system, such as a 77K low-temperature system and a low-temperature system below the 77K temperature, and the low-temperature system is used for cooling the high-temperature superconducting bulk material so as to enable the high-temperature superconducting bulk material to be in a superconducting state; the high-temperature superconducting block is reliably fixed in a low-temperature system, and no internal stress such as extrusion exists between magnets. All the high-temperature superconducting coil magnets satisfy the following conditions: the high temperature superconducting coil magnet comprises a cryogenic system, such as a 77K cryogenic system and a cryogenic system below 77K temperature, and the high temperature superconducting coil is in a superconducting state and is reliably fixed in the cryogenic system.
For example, the high temperature superconducting bulk magnet on the side wall of the track beam in the braking area and the high temperature superconducting coil magnet can be communicated and are in the same low temperature system.

In other words, the high-temperature superconducting bulk magnet region is arranged and filled with the high-temperature superconducting bulk except the superconducting coil magnet region, and is reliably fixed at the corresponding position in the low-temperature system, so that the high-temperature superconducting bulk magnet region and the superconducting coil can share one low-temperature system.

The trapezoidal superconducting coil is reliably fixed at a corresponding position in the cryogenic system.
Alternatively, the high-temperature superconducting coil magnets on the side walls of the braking-area track beam are arranged in the direction of movement of the vehicle body, and the plurality of superconducting coils are the same in size, so that the high-temperature superconducting coil magnets are rectangular.
According to an embodiment of the invention, the vehicle-mounted power magnet 1 is at least one of: magnetizers, permanent magnets and electromagnets.
According to an embodiment of the invention, the vehicle mounted hovering magnet 2 is at least one of: permanent magnets and electromagnets.
The above description of the vehicle-mounted power magnet and the vehicle-mounted hover magnet is merely exemplary, and is not intended to limit the present invention.
According to an embodiment of the present invention, the vehicle-mounted sensing unit 3 is a vehicle-mounted sensing board.
According to an embodiment of the present invention, the sidewall sensing unit is a sidewall sensing coil or a sidewall sensing plate.
The working principle of the high-temperature superconducting magnetic levitation start-stop system described in the above embodiment of the present invention is described below.
When the train needs to be braked, the magnetic suspension train moves from the conventional suspension propulsion area to the braking area at a high speed in the braking process. The vehicle-mounted power magnet 1 can provide a strong and stable excitation magnetic field, and the closed-loop superconducting coil on the side wall of the track beam cuts magnetic induction lines generated by the moving vehicle-mounted power magnet 1 in the moving process of the train, so that strong eddy current is generated in the superconducting coil, an eddy current magnetic field is further generated to react on the vehicle-mounted power magnet 1, and eddy current braking is carried out on the train. Because the superconducting coil has almost no resistance in a low-temperature superconducting state, the generated eddy current is larger than that of a common induction coil or an induction plate, so that larger braking force is generated, meanwhile, the problems of serious heating and the like caused by overlarge current cannot be generated in a low-temperature system, and latent heat can be generated through the low-temperature system. Under the condition that the size of the arranged superconducting coils is continuously reduced along the moving direction of the train and the superconducting bulk material area (superconducting bulk magnet area) is continuously increased, because the speed of the train is continuously reduced, the required direct braking force is reduced, and meanwhile, the slowly-increased high-temperature superconducting bulk material area provides guiding force for the side guiding dimension. The high temperature bulk superconductor region provides the force necessary to stabilize the system for negative feedback.
FIG. 4 is a schematic diagram of the operating principle of a second generation high temperature superconducting bulk according to an embodiment of the present invention.
The high-temperature superconducting bulk material in the embodiment of the invention can be a second-generation high-temperature superconducting bulk material (the working principle is shown in fig. 4). The magnetic field of the vehicle-mounted magnet has a magnetic field gradient in the vertical direction of motion. After cooling, the magnet enters a second-generation high-temperature superconducting bulk magnet in a superconducting state, and a pinning center is formed due to crystal defects such as vacancies, impurities, dislocation and the like in the magnet, so that magnetic flux is captured. When the vehicle-mounted magnet approaches the side wall of the track beam, the magnetic field environment of the superconducting magnet block begins to change, induction current is generated inside the superconducting block, and the current exists all the time because the superconductor has zero resistance. As can be seen from lenz's law, the induced current generated will create a resistance that will impede the vehicle from further travel in the direction of motion. If the vehicle-mounted magnet is closer to the superconducting block area of the track beam, the magnetic field intensity of the vehicle-mounted magnet is stronger, the change rate of the magnetic field is larger, and the generated induced current and the generated guide force are larger and larger.
Further, during the hovering process, the train stops in the hovering area after passing through the braking area for braking. Establishing a stable state of the vehicle body guiding direction by using the superconducting block magnets on the side walls of the track beam in the area and the vehicle-mounted power magnets; establishing a stable state of the suspension direction of the vehicle body by using the superconducting bulk magnet at the bottom of the track beam and the vehicle-mounted hovering magnet; meanwhile, due to the magnetic flux pinning principle, the superconducting bulk magnet systems on the side wall and the bottom enable the train to be subjected to restoring force in the running direction, and the stable state of the running direction of the train body is guaranteed.
Furthermore, during the propulsion process of the induction motor, the train is provided with an induction motor system consisting of a vehicle-mounted induction plate and a ground starting stator coil. The induction motor accelerates the train in the induction motor propulsion area to the floating speed of the train in the conventional suspension propulsion area. The induction motor can be used as an independent system in a traction system, and the required power is small because the induction motor only accelerates to the floating speed. Meanwhile, the low-speed section propelling process of the propelling motor in the conventional suspension propelling area is reduced, and the overall efficiency of the motor in the conventional suspension propelling area is improved.
Further, during the unpowered detection zone, the train utilizes inertial motion while the on-board power magnets and the sensing units on the side walls of the track beam still provide the levitation force required to levitate the train. When the train runs at the section, the position and speed signals can be monitored by the positioning speed measuring system, and are transmitted to the motor control system of the conventional suspension propulsion system, so that the control strategy is adjusted in advance, and the train can stably enter the conventional suspension propulsion system and normally run.
