Abstract

The present invention relates to a coupled ceramic capacitor with a combined electrode. The ceramic capacitor includes a ceramic dielectric (301) configured in the shape of a flat cylinder, and silver film electrodes (302) covered on the cylindrical surfaces of the two ends of the ceramic dielectric. The radius of curvature of the edge of each silver film electrode is r. The ceramic capacitor further comprises a copper electrode (303) covered onto the outer sides of the silver film electrodes and used for wrapping the edges of the silver film electrodes to reduce the strength of the electric field at the edges of the silver film electrodes. According to the technical scheme of the invention, the strength of the electric field at the edges of the silver film electrodes is remarkably reduced. Meanwhile, the serious distortion problem of the electric field at the edges of the electrodes under a high voltage is solved.

Description

technical field [0001] The invention relates to a coupling ceramic capacitor, in particular to a coupling ceramic capacitor with composite electrodes. Background technique [0002] Coupling ceramic capacitors are devices used in high-voltage electrical equipment, which can provide detection signal sources for instruments such as caller display devices, capacitive voltage dividers, and partial discharge sensors. When the coupling ceramic capacitor is connected to a high-voltage conductor, it will directly withstand high voltage, and there is a risk of insulation breakdown. Instruments such as caller indicators, capacitive voltage dividers, and partial discharge sensors are auxiliary equipment for high-voltage electrical equipment. Users require that the auxiliary equipment cannot affect the safe operation of the main equipment. Therefore, the coupling ceramic capacitor and the final product packaged with it require that its AC withstand voltage, partial discharge and other i...
