Description

technical field

[0001] The invention relates to the field of on-off of a superconducting coil quench protection signal transmission line, in particular to an automatic test method for the on-off of a superconducting coil quench protection signal transmission line in a fusion device. Background technique

[0002] The invention relates to a quench protection system in a fusion device. Even if the superconducting magnets of all superconducting tokamaks are within the range of their designed operating parameters, quenching will occur under certain operating conditions (superconducting coils from superconducting state to Normal state transition), if the quench protection cannot be performed in time, the energy stored in the magnet will be discharged, and the superconducting magnet or some important components associated with it will be damaged or burned. One end of the original quench protection signal in the EAST fusion device is taken from the superconducting coil, and the othe...
