CAPACITANCE VALUE RAPID-SWITCHING VACUUM CAPACITOR

Disclosed in the present invention is a capacitance value rapid-switching vacuum capacitor, comprising: a casing, a first electrode group and a second electrode group, a vacuum chamber being arranged in the casing, the first electrode group and the second electrode group being mutually coupled and accommodated in the vacuum chamber, an electromagnetic drive mechanism being mounted on the outer side of one end of the casing, and the electromagnetic drive mechanism being capable of driving the first electrode group to move relative to the second electrode group so that the vacuum capacitor is switched between two capacitance value states. The capacitance value rapid-switching vacuum capacitor uses the electromagnetic drive mechanism, so that rapid adjustment and switching of capacitance values of the vacuum capacitor are achieved, and the capacitance value switching time of the vacuum capacitor can be within one hundred milliseconds, thus meeting the requirement of a vacuum capacitor application device for rapi
