<p>PROBLEM TO BE SOLVED: To obtain a noncontact induction current collector wherein increase of heating value of liquid helium cooling superconducting magnets can be restrained, by sufficiently preventing generation of electromagnetical or mechanical vibration and heat generation of vacuum heat insulating vessels or the insides, and reliability of the superconducting magnets can be improved. SOLUTION: This noncontact induction current collector is equipped with vacuum heat insulating vessels 4 arranged on both sides of an electromagnetic levitation moving body, radiation shields 3 which are accommodated in the vacuum heat insulating vessels 4 in order to prevent invasion of radiation heat to the inside, superconducting magnet vessels 2 which are accommodated in the radiation shields 3 as liquid helium tanks, superconducting magnets 1 accommodated in the superconducting magnet vessels 2, and current collecting coils which are fixed on the surfaces of the vacuum heat insulating vessels 4 against magnetic field generating sources for running or levitating the electromagnetic levitation moving body. At this time, intermediate parts 6 composed of high- modulus material are interposed between the vacuum heat insulating vessels 4 and the current collecting coils.</p> |
