Abstract
A capacitance value fast-placing vacuum capacitor includes: a housing, a first electrode group and a second electrode group. A vacuum chamber is provided in the housing. The first electrode group and the second electrode group are mutually coupled and accommodated in the vacuum chamber. An electromagnetic drive mechanism is mounted on the outer side of one end of the housing. The electromagnetic drive mechanism is capable of driving the first electrode group to shift relative to the second electrode group, the vacuum capacitor is switched between two capacitance value states. In the capacitance value rapid-switching vacuum capacitor, the electromagnetic drive mechanism is configured for rapidly adjusting and switching capacitance values of the vacuum capacitor, the capacitance value switching time of the vacuum capacitor is within one hundred milliseconds, thus meeting the requirement of an application device of the vacuum capacitor for rapid matching of an impedance matcher.
