Abstract

The invention discloses a high-temperature super-conduction magnetic suspension track with a cooling system. A track bottom plate (1) is included. Train supporting structures are symmetrically arranged on the two sides of the track bottom plate (1). Each train supporting structure comprises a track beam (5) perpendicular to the track bottom plate (1) and a track face (2) which is arranged on the top of the track beam (5) and is perpendicular to the track beam (5), wherein a permanent magnet (3) is arranged on the top of the track face (2). A drive mechanism is arranged between the track supporting structures and comprises a linear motor rotor support (6) perpendicular to the track bottom plate (1), and a linear motor rotor (4) arranged on the linear motor rotor support (6). The invention further discloses a train running method. According to the high-temperature super-conduction magnetic suspension track, a train can be kept in a suspension state on the track, meanwhile, running of thetrain is controlled through control over a train drive structure via a control system, and the effect of accurate control is achieved.

Description

technical field [0001] The invention belongs to the field of high-temperature superconducting maglev tracks, and more specifically relates to a high-temperature superconducting maglev track with a cooling system and a method for operating a maglev train. Background technique [0002] At present, both at home and abroad are stepping up the development of high-temperature superconducting maglev trains. Magnetic levitation trains are divided into two types: normal conduction and superconduction. The normal conduction uses electromagnetic levitation technology. The mechanism of levitation relies on the magnetic field generated by the electromagnet to attract the F rail to make the train levitate. The constant conduction maglev train has been commercialized at home and abroad. Applications such as Shanghai Airport Maglev, Changsha Maglev and Beijing S1 Line Maglev. Superconductivity relies on the interaction between the magnetic field generated by the superconductor at low tempe...

Problems solved by technology

Applying high-temperature superconducting technology to the environment, the theoretical train speed can reach 4000km / h. With people's pursuit of speed, high-temperature superconducting maglev trains have broad prospects, but the related complete set of technologies is in its infancy. The high-temperature superconducting magnetic levitation track is also in the research stage

[0003] The linear motor rotor in HTS maglev needs long-term continuous operation when the train is running, and the long-term continuous operation of the motor will generate a large amount of heat energy, making the linear motor rotor in a high temperature state for a long time, reducing the service life of the motor and increasing energy consumption
