Vacuum capacitor

摘要

A vacuum capacitor includes a fixed electrode, a movable electrode, a movable electrode shaft, a magnetic flux receiving unit, a magnetic flux generating unit and a capacitance control unit. The fixed electrode is formed from a plurality of electrode members in a vacuum casing. The movable electrode is formed from a plurality of electrode members arranged in gaps formed between the electrode members of the fixed electrode in the vacuum casing. The movable electrode shaft supports the movable electrode. Capacitance appearing between the movable electrode and the fixed electrode is varied by rotation of the movable electrode shaft. The magnetic flux receiving unit rotates the movable electrode shaft in the vacuum casing. The magnetic flux generating unit is located outside the vacuum casing and rotates the magnetic flux receiving unit by magnetic attraction. The capacitance control unit rotates the magnetic flux generating unit.
