Numerical simulation of laser triggered SF6 gap switch delay modeling

A 0-dimension model of laser triggered SF6 gap switch is established and the numerical results compared with a series of experimental data presented by Woodworth and Li hong-tao in the paper. The calculated delay is in agreement with the experimental one. When gas pressure is constant, delay decreases with the increase of laser energy and percent of self-breakdown voltage(SBV). The slope of the curve of delay vs percent of SBV for different laser energy also decreases with the increase of laser energy and percent of SBV. When laser energy is constant, delay decreases with the decrease of pressure and the increase of voltage, and the curve slope of delay vs voltage for different pressure decreases with the increase of voltage. The delay decreases as pressure increases for constant V/p.
