空气火花间隙开关的剩余电阻仿真
Residual resistance simulation of an air spark gap switch
摘要：
在两种理论模型下对空气火花隙进行了数值模拟。动力学模型[1]允许我们计算剩余电阻（0.2 - 0.4欧姆，用于我们选择的电路参数）、火花隙通道宽度、电子数密度、迁移率、电导率、电离度、放电通道中的磁场、通道电感和电子漂移速度的时间依赖性。模拟一个真实的电路，并考虑到火花隙的残余电阻表现出良好的协议，这两个模型与实验数据，而不考虑这个电阻高估了电路中的最大电流约5%。
英文摘要：
The numerical simulation of an air spark gap has been carried within two theoretical models. The kinetic one [1] allowed us to calculate time dependencies for the residual resistance (0.2 - 0.4 Ohm for our selection of a circuit parameters), the spark gap channel width, the electron number density, the mobility, the conductivity, the ionization degree, the magnetic field in the discharge channel, the channel inductance and the electron drift velocity. Simulating a real circuit and taking into account a spark gap residual resistance demonstrates good agreement of both models with the experimental data, while that without taking into account this resistance overestimates the maximal current in the circuit by approximately 5%.
