Single channel electric spark source and discharge experimental study

本文介绍了一套单通道电火花震源系统,主要包括充电和放电两个单元。同时搭建了一个实验平台,由充电机、电火花震源、数字示波器、高压探头和罗氏线圈电流传感器等组成。在此基础上进行实验研究与总结,通过采用本文所述的单通道电火花震源进行放电实验,在不同电极材料、电压和电极间距条件下,对水中等离子体的电特性进行了分析。使用ORIGIN数据分析软件观察了等离子通道的电阻和放电功率在时间域的变化趋势。通过比较总结,得出了放电电流、放电电阻和放电效率等与控制条件之间的关系规律。本文所提及的系列实验为自封闭电极腔等离子体震源的设计提供了参考。

In this paper,a set of single channel electric spark source system is introduced,which mainly includes two units of charging and discharging. At the same time,the experiment platform is built,which is composed of charger,electric spark source,digital oscilloscope,voltage probe,and Rogowski coil current sensor. The discharge experiment is carried out by using the single channel electric spark source. Under different electrode materials,different voltages and electrode spacings,the electrical characteristics of the plasma in water are analyzed. By using the ORIGIN data analysis software,the variation trends of the plasma channel resistance and the discharge power in the time domain are observed. By comparison,the relationship between discharge current,discharge resistance,discharge efficiency and control conditions are obtained. The series experiments mentioned in this paper provide a reference for the design of the plasma source of the self enclosed cavity.
