SUPERCONDUCTIVE COIL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a superconductive coil device which can prevent in advance a burning loss due to quenching. SOLUTION: This superconductive coil device is provided with a bridge circuit 11 connecting with both ends of superconductive coils 2 and 3 respectively and a device 6 for detecting quenching which can judge a possibility of quenching by removing noises in on output from the bridge circuit 11 and comparing it with the predetemined threshold value.
