Document Type and Number:
Japanese Patent JP2529963
Kind Code:
B2
Abstract:
PURPOSE:To prevent dielectric breakdown from being generated, by preventing a connecting conductor or the like from coming in direct contact with, with gas helium after a current lead is cooled. CONSTITUTION:To the gas helium discharge slot 2a of a current lead 2, the linear communicating vessel 10 of high electrical and on the downstream side of gas helium, the vessel 11 of the same material is connected; thus a structure communicating with an exhaust passage 5 is composed. Accordingly, after the current lead 2 is cooled by the gas helium of a low temperature gasified in a rotor, the gas helium passes via the communicating vessel 10 and the insulating vessel 11 and flows in the direction of an arrow head. A space 12 formed by the insulations is separated from a space 6 formed at the end section of a shaft 13, and the space 6 is filled up with air under atmospheric pressure. At a result, against high application voltage, discharge (dielectric breakdown) from the current lead 2 or a connecting conductor 4 to the shaft 13 (earth) is not generated.
