    Abstract
  •   Introduction  The huge energy stored in the superconducting magnet in quench state is transferred and consumed by China Fusion Engineering Experimental Reactor (CFETR) quench protection system to prevent it from damage. In order to meet the design requirements of CFETR quench protection system, the overall design of the system is carried out in this paper.
      Method  The basic principle and action logic of quench protection system were introduced, and the system design parameters of toroidal field coil (TF) quench protection unit and poloidal field / central solenoid coil (PF/CS) quench protection unit were described respectively.
      Result  The two different schemes currently designed are analyzed. The topological structure and the switching logic of the quench protection switch, and the design requirements of other components are mainly introduced.
      Conclusion  For the overall design scheme of the system, due to low cost, less land occupation, relatively mature technology and high feasibility, the mechanical DC switch with artificial current zero-crossing is the preferred scheme. Taking into account good prospects for development, hybrid DC switch with mechanical switch and solid-state switch is chosen as alternative.
