摘要：

Experiment Advanced Superconducting Tokamak (EAST) has a high stored energy superconducting toroidal field (TF) magnet system, so a quench protection is required to discharge the TF coils stored energy. This paper proposes a quench protection scheme of the EAST toroidal superconducting magnet through the forced commutation analysis of DC circuit breaker (DCCB) paralleling fuse, in the meantime, two pyrobreakers (PB) are used as a backup to enhance reliability. Based on the requirements of quench protection of EAST toroidal field magnet, the main parameters are selected. Experimental results demonstrate the validity of the proposed case.
