AI Technical Summary
In the existing technology, the rising temperature of the magnetic poles of the levitation electromagnet causes damage to the insulation layer between the coil turns. The small operating space and large number of magnetic poles during measurement result in low accuracy of the levitation electromagnet's operating conditions, posing a safety hazard to the operation of maglev trains.
Design a magnetic pole life measurement device for a conventional high-speed magnetic levitation electromagnet, comprising an integrally formed measuring part and a contact part. The measuring part is attached to the top surface of the levitation electromagnet to install measuring components to measure magnetic pole parameters. The contact part is in contact with the peripheral side of the levitation electromagnet. High-precision measurements are performed using Hall probes and thermocouple probes to calculate life evaluation coefficients to assess magnetic pole life.
This improves the accuracy of measurements of levitation electromagnets under operating conditions, reduces safety hazards during maglev train operation, and ensures the stability and accuracy of measurements.
