Long stator power supply section used for maglev train and long stator linear motor

Abstract

The invention discloses a long stator power supply section used for a maglev train and the long stator linear motor. The section comprises a plurality of stator core modules and stator coils equal innumber to the stator core modules, wherein the plurality of stator coils are embedded in the stator core modules one by one, two ends of each stator coil are provided with joints, the stator coils onevery two adjacent stator core modules are detachably connected by joints, and the joints of the stator coils on the stator core modules at both ends are connected to the feed cables. By adopting thelong stator power supply section provided by the invention, the construction processes are performed simultaneously; the on-site construction period is shortened; the paving precision of the long stator core on the track beam is improved; large-scale special winding equipment is not required; the cost is low, difficulty level in the disassembly and the re-embedding is low; circuit repair time is short; and the waste of stator coils is reduced.

Description

technical field [0001] The invention relates to the technical field of long-stator linear motors, in particular to a long-stator power supply section and a long-stator linear motor for maglev trains. Background technique [0002] With the development of transportation, maglev trains have become the travel choice of more and more people due to their advantages of high speed and high safety. Maglev trains usually use long stator linear motors. The long stator linear motor installed on the track beam is composed of multiple long stator power supply sections (typical length is 1200m), specifically, please refer to figure 1 , figure 1 It is a structural schematic diagram of a long stator power supply section in a long stator linear motor in the prior art. Each long stator power supply section is composed of a long stator core (consisting of multiple stator core modules, the typical length of which is 1032mm) and a long stator coil. Specifically, in each long stator power supp...

AI Technical Summary

Problems solved by technology

[0004] 1) When installing the long stator power supply section, the stator core module should be paved on the track beam first, and then the track beam should be installed on the line to form a long stator core, and then completed with large-scale special winding equipment The embedded winding of long stator coils forms a long stator power supply section. On the one hand, the construction process is serial and the construction period is long; on the other hand, large-scale special winding equipment is required, which is costly

[0005] 2) The length of the long stator power supply section is hundreds of meters or even thousands of meters. If one of the stator core modules is damaged and needs to be replaced, the entire long stator coil needs to be disassembled first, and then the damaged stator core module needs to be replaced. After installing a new stator core module, rewind the long stator coil; if the long stator coil is damaged, after replacing the damaged long stator coil, you need to rewind the entire long stator coil. On the one hand, because the long stator coil is very long, Increases the difficulty of disassembly and rewinding, causing the line to stop transportation, and the repair time is measured in weeks; on the other hand, the waste of material for long stator coils is serious
