A rapid switch controller comprises a cabinet, an integrated switch power supply, an opening thyristor module, a closing thyristor module, a trigger plate and a control plate, wherein the integrated switch power supply, the opening thyristor module, the closing thyristor module, the trigger plate and the control panel are installed in the cabinet in a rapid switchgear, the integrated switch power supply, the opening thyristor module, the closing thyristor module and the trigger plate are sequentially installed in the cabinet body, the integration switch power supply and the control panel are connected through a signal cable JP4, the control panel and the trigger plate are connected with each other through a Phoenix terminal JP5, a Phoenix terminal JP6 and a wire, the control panel is connected with an external controller through a fiber, and the trigger plate is connected with the external controller. The rapid switch controller has fewer board cards, less fault points, and simpler logic structures. Faults are easy to find, the power-off maintenance time of equipment is shortened, and the power supply reliability is substantially improved.
