High-Voltage Flat Capacitor Based on Metal-Polymer Combined Electrode

Abstract

The invention belongs to the technical field of pulsed power, in particular to a plate capacitor based on a metal polymer composite electrode, which aims at improving the voltage withstand strength along the surface of the existing peaking capacitor and outputting a higher amplitude electromagnetic pulse waveform. The peaking capacitor includes a plurality of metal-polymer composite electrodes coaxially stacked together. A thin film medium is sandwiched between two adjacent metal-polymer composite electrodes. An upper pressing plate and a lower pressing plate are respectively arranged on the outside of the two metal-polymer composite electrodes located at the end, and the upper pressure plate and the lower pressure plate are compressed by a pull rod penetrating through the edges of the upper pressure plate and the low pressure plate. The metal-polymer composite electrode includes a polymer support ring, a polymer support ring and a bonding agent. The metal round disc electrode and thepolymer support ring are arranged concentrically, and the outside of the metal electrode is connected with the inner side of the polymer support ring by using an adhesive, and the outer diameter of the polymer support ring is larger than the outer diameter of the thin film medium.

technical field [0001] The invention belongs to the technical field of pulse power, and relates to an electromagnetic pulse simulation device, in particular to a flat-plate peaking capacitor used in the electromagnetic pulse simulation device. Background technique [0002] In the electromagnetic pulse simulation device, in order to meet the requirements of relevant IEC standards or national standards for electromagnetic pulse waveforms and realize the output of nanosecond frontier double-exponential pulse waveforms, multi-stage pulse compression technology is usually used to compress the waveforms generated by the primary pulse source. Among them, the peaking capacitor, as one of the key components of the electromagnetic pulse simulation device, plays a vital role in the effect of pulse compression. The inductance and withstand voltage capability of the peaking capacitor are two parameters that restrict each other. On the one hand, in order to improve the ability of waveform...

AI Technical Summary

Problems solved by technology

[0004] As the experimental object of electromagnetic pulse gradually develops from a single device experiment to a whole system experiment, the simulator is required to provide a larger experimental space to accommodate the entire system, and provide a higher amplitude electromagnetic pulse environment to realize the threshold experiment of the whole system. The output voltage index of the simulator needs to be further improved from the current level, which puts forward higher requirements for the insulation performance of the peaking capacitor, and the existing technology cannot meet these requirements
