“Low Heat In Leak Slip Ring Shaft Arrangement For High Temperature Superconducting Synchronous Machine”
Abstract: Described herein is a system and method for reducing heat-in-leak through slip-ring shaft assembly for high temperature superconducting synchronous machine comprises a rotating cryostat (101) having a superconducting pole coils (118) which are maintained at cryogenic temperature and excited through the low heat-in-leak slip-ring shaft assembly (200). A cryogen system having a cold cryogen pipe (107) and a warm cryogen pipe (108) configured as inlet and outlet from the superconducting coils (118). An at least one positive electrode (205) and the negative electrode (206) are electrically fastened to each one of a cryogenic electrical current feed through and the positive slip ring (211) and the negative slip rings (212) are electrically isolated from the slip ring shaft (201) and an electromagnetic torque is shared, when placed in mechanical torque transmission train of a shaft body which reduces the heat to the cryogenic system of the low heat-in-leak slip-ring shaft assembly (200).
