Description

Magnetic levitation line power rail measuring ruler Technical Field The utility model relates to rail transit, in particular to a magnetic levitation line power rail measuring scale. Background When the magnetic levitation train is stopped or runs within 100 km/h, external power supply is needed, and direct current is supplied. Contact shoes are used between the power rail and the train to conduct electricity. The current collector shoe and the power rail of the train need to be in close contact. In the actual operation process, when the contact clearance between the power rail and the current-collecting boot is too large, poor contact of the metal surface can be caused, and the arcing phenomenon is caused.
