The invention discloses a quick energy-storage type vacuum switch which comprises an outer shell, a main shielding case, a moving electrode, a fixed electrode, a moving electrode connecting rod, a fixed electrode connecting rod, a corrugated pipe, a switching-on cam and an energy storage operation circuit used for driving the switching-in cam to rotate. The main shielding case, the moving electrode, the fixed electrode and the corrugated pipe are all arranged in the outer shell. The moving electrode and the fixed electrode are connected with the moving electrode connecting rod and the fixed electrode connecting rod which are extended out from the outer shell respectively. The moving electrode and the fixed electrode are close and are both located in a space defined by the main shielding case. The switching-on cam is connected with the moving electrode connecting rod, the energy storage operation circuit drives the switching-on cam to drive the moving electrode connecting rod, and therefore the moving electrode and the fixed electrode are in contact or separated from each other. According to the quick energy-storage type vacuum switch, even under a high-voltage/ultrahigh-voltage power system of 110 kV or higher than 110 kV, the quick enough disconnecting speed of the moving electrode and the fixed electrode can still be guaranteed, and therefore a good insulation effect is achieved.
