Problems solved by technology

Due to the airtight structure of the gas switch, there are high-temperature arc channels and strong electromagnetic interference inside it during the shock discharge process, which is not conducive to the detection of various physical and chemical parameters of the shock wave.

In addition, the shock wave detection system in the prior art has a complex structure and cannot accurately simulate the shock wave under the arc discharge condition, and the detection index is single, which leads to the inability to accurately obtain the physical and chemical properties of the arc discharge induced shock wave, which is not conducive to the development of Performance research of high-power gas switch in high energy consumption scenarios
