The utility model discloses an explosion-proof filling medium capacitor, comprising a capacitor outer shell, an upper cover welded on the bottom end of the capacitor outer shell, a wiring terminal fixedly installed on the upper surface of the upper cover, a grounding pole fixedly installed on the upper surface of the upper cover, a spring plate fixedly installed below the upper cover, and a grounding pole fixedly installed on the lower surface of the spring plate. A core is fixedly installed below the spring plate, and cooling fins are fixedly installed on the outer side of the core. The extension plate connected through the sliding block and the first spring is arranged in the capacitor, so that when the filling agent expands, the extension plate is extruded to slide outwards until the filling agent is cooled to restore, the extension plate retracts to the original position through the elastic effect of the first spring, and when the temperature in the capacitor is too high or the voltage is too high, the ex
