Research on electromagnetic compatibility of maglev train on high-speed maglev demonstration line

Taking maglev train of high speed maglev demonstration line as the research object, the electromagnetic compatibility performance of this train is analyzed. The magnetic field of external electromagnetic radiation emitted by the vehicle in the frequency range of 150kHz-30MHz and the electric field emitted by the vehicle in the frequency range of 30MHz-1GHz are tested. The magnetic flux density (DC-20kHz) of the guest room area was tested and the electromagnetic protection requirements for the public and professional personnel were assessed. The test results show that the magnetic field and electric field radiated by the vehicle meet the limit requirements, and the magnetic flux density in the passenger room also meets the standard limit requirements.
