A dry-type high-voltage low-inductance coaxial peaking capacitor and its manufacturing process

Abstract

The invention provides a dry-type high-voltage low-inductance coaxial peaking capacitor and a manufacturing process. The peaking capacitor includes a peaking capacitor high-voltage electrode, an open metal cylinder electrode, and a peaking capacitor ground electrode arranged coaxially from the inside to the outside. There are multiple open metal cylinder electrodes; multiple layers are filled between two adjacent electrodes The organic film is used as the solid medium of the capacitor; the outer surface of the high voltage electrode of the peaking capacitor and the inner and outer surfaces of the open metal cylinder electrode have ring-shaped electrode bosses as the effective electrodes of the capacitor; two adjacent electrodes and the multilayer organic dielectric film filled between them constitute a circle Cylinder capacitors, two adjacent cylindrical capacitors share an open metal cylinder electrode. The peaking capacitor is actually a low-inductance capacitor formed by connecting multiple coaxial cylindrical capacitors in series without leads; the electrode thickness is designed to be on the order of millimeters, greatly The surface electric field is reduced and the withstand voltage is improved; the peaking capacitor has a simple structure and high withstand voltage, which meets the requirements of low inductance and high voltage.
