A pulse power capacitor

Abstract

A pulse power capacitor, including several capacitors and two metal electrode sheets, several capacitors are connected in parallel through the two metal electrode sheets to form a parallel capacitor bank, several capacitors are stacked, and buffer pads are arranged between adjacent two capacitors, electrodes on both sides of the capacitor They are respectively connected to two metal electrode sheets, and the metal electrode sheet is formed with several electrode plates for connecting capacitor electrodes, and several electrode plates are connected as a whole through expansion joints connected between two adjacent electrode plates, and are led out from the edge of the metal electrode sheet several pins. The present invention can effectively buffer the expansion that occurs when the capacitor is in operation by setting a cushion plate between two adjacent capacitors and connecting the two adjacent electrode plates through an expansion joint, so that the gap between the capacitor and the capacitor and between the capacitor and the metal can be effectively buffered. The electrode sheets have better expansion buffering capacity, are not easy to separate from each other due to expansion, and can effectively prevent capacitor breakdown and explosion caused by expansion, with higher reliability and safety.

Description

technical field [0001] The invention relates to a capacitor, in particular to a pulse power capacitor. Background technique [0002] At present, in the existing pulse power capacitors, in order to increase the capacitor capacitance and energy storage energy, multiple capacitors are usually connected in parallel as energy storage units, and usually multiple capacitors are connected in parallel through electrode sheets connected to capacitor electrodes. However, the pulse power capacitor with this structure expands due to the heating of the capacitor and the change of the ambient temperature during operation. Therefore, the capacitor and the capacitor or between the capacitor and the electrode sheet are easily squeezed due to expansion, and the capacitor is easily damaged by the expansion stress. However, cracks are caused, and there is a danger of expansion breakdown and explosion accidents, and the reliability and safety are low. Contents of the invention [0003] The mai...
