The invention relates to a safe discharge grounding system and method for converter valve capacitor short circuit. The safe discharge grounding system comprises a capacitor discharge and short circuit structure and a moving contact action transmission structure. The capacitor discharging and short-circuit structure comprises a sliding connecting rod, a small resistor, a moving contact and a static contact. The contact mounting beam is fixedly connected with a plurality of small resistors, the sliding connecting rod is fixed on the contact mounting beam, the moving contact is fixedly connected on the sliding connecting rod, and the static contact is fixed on the contact mounting beam; the moving contact action transmission structure comprises an operating mechanism, a ground supporting rod and an interlayer supporting rod; the operating mechanism is connected with the ground supporting rod through a bearing; the top ends of the ground supporting rods are connected with the translation homonymous mechanisms, an
