Abstract
The invention discloses an improved structure of a water-cooling ceramic vacuum capacitor. The water-cooling ceramic vacuum capacitor comprises a pull rod, a guide sleeve, a bellows, a base and an electrode base, wherein one end of the pull rod is provided with a water inlet, the other end of the pull rod is connected to the electrode base, and the water inlet is communicated with the interior of a connector; the guide sleeve is fixedly arranged on the outer side of the pull rod in a sleeved mode, the base is fixedly connected to the outer side of one end, facing toward the water inlet of the pull rod, of the guide sleeve, the bellows is positioned and arranged outside the guide sleeve and the connector in a sleeved mode, one end of the bellows is fixedly connected with the base, the other end of the bellows is fixedly connected with the electrode base, and besides, a water outlet communicated with the interior of the bellows is formed in the base; spiral grooves which spirally ascend in the axial direction are formed in the peripheral face of the guide sleeve and the peripheral face of the connector. Thus, when the water-cooling ceramic vacuum capacitor works, cooling water makes centrifugal rotation and flows in the bellows, the temperature of the bellows in the high frequency working state is lowered, and the mechanical service life of the water-cooling ceramic vacuum capacitor is prolonged.
