Dry-type high-voltage low-inductance coaxial peaking capacitor and manufacturing process

Abstract

The invention provides a dry-type high-voltage low-inductance coaxial peaking capacitor and a manufacturing process. The peaking capacitor comprises a peaking capacitor high-voltage electrode, a plurality of opening metal cylinder electrodes and a peaking capacitor ground electrode which are sequentially and coaxially arranged from inside to outside, wherein a multi-layer organic film fills the space between adjacent two electrodes as a capacitor solid medium; annular electrode bosses are arranged on the outer surface of the peaking capacitor high-voltage electrode and the inner and outer surfaces of the opening metal cylinder electrodes to serve as effective electrodes of the capacitor; two adjacent electrodes and the multi-layer organic dielectric film filling the space between the two adjacent electrodes form a cylindrical capacitor; two adjacent cylindrical capacitors share one open metal cylinder electrode; and the peaking capacitor is actually a low-inductance capacitor formed bysequentially connecting a plurality of coaxial cylindrical capacitors in series in a leadless mode. The thickness of the electrode is designed to be millimeter-scale, so that the surface electric field is greatly reduced, and the withstand voltage is improved; the peaking capacitor is simple in structure and high in withstand voltage, and meets the requirements of low inductance and high voltage.
