The energy distribution structure and dynamic characteristics of energy release in electrostatic discharge process

The detail structure of energy output and the dynamic characteristics of electric spark discharge process have been studied to calculate the energy of electric spark induced plasma under different discharge condition accurately. A series of electric spark discharge experiments were conducted with the capacitor stored energy in the range of 10J 100J and 1000J respectively. And the resistance of wire, switch and plasma between electrodes were evaluated by different methods. An optimized method for electric resistance evaluation of the full discharge circuit, three poles switch and electric spark induced plasma during the discharge process was put forward. The electric energy consumed by wire, electric switch and electric spark induced plasma between electrodes were obtained by Joules law. The structure of energy distribution and the dynamic process of energy release during the capacitor discharge process have been studied. Experiments results showed that, with the increase of capacitor released energy, the duration of discharge process becomes longer, and the energy of plasma accounts for more in the capacitor released energy. The dynamic resistance of plasma and three poles switch obtained by energy conversation law is more precise than that obtained by the parameters of electric current oscillation during the discharge process.
