高脈沖重復(fù)頻率的氣體火花開關(guān)研究
[Abstract]:In recent years, with the development of repetitive pulse power technology, gas spark switch with high pulse repetition rate is regarded as an important part of repetitive frequency pulse power device. In this paper, the high pulse repetition rate gas spark switch is studied by means of theoretical summary, numerical simulation and experiment. Firstly, the voltage doubling rectifier circuit is simulated by LT spice simulation software, and the influence of the parameters on the output voltage waveform is summarized. Based on the simulation, a set of HVDC power supply system is developed. Through theoretical analysis and calculation, a high voltage measuring system is developed, which is composed of resistor divider and pulse divider. Finally, different load systems are made according to the experimental requirements. An experimental platform of gas spark switch is made by assembling each system through electrical structure design. According to the empirical formula of breakdown voltage of parallel electrode structure, the structure parameters of main electrode of gas spark switch are determined. According to the relationship between the peak value of the breakdown voltage and the distance between the poles, the climbing distance of the external insulation support of the switch is determined, and then the electric field simulation and circuit simulation of the switch are carried out, and the parasitic inductance and the parasitic resistance of the switch are obtained. At the same time, the ability of transmitting large current of switch is preliminarily grasped. After the material of the switch is determined, the engineering drawing of the switch is designed, and a gas spark switch with high pulse repetition rate is made. Finally, the self-breakdown experiment, single trigger experiment and repeated frequency trigger experiment are carried out on the experimental platform. A large number of theoretical and experimental studies are carried out on the plasma channel model of the switch during the conduction process. Finally, the equivalent circuit model of plasma channel in series between time-varying resistance and time-varying inductance is established, and the plasma channel model in different dielectric breakdown process is compared and the theoretical explanation is tried.
