Development of discharge in water-salt solution at voltages above the threshold value
The process of breakdown of the pin-plane electrode geometry at an interelectrode gap of 1 cm in a 3% NaCl solution in water is investigated. Single voltage pulses with a duration of about 2 ms and an amplitude of up to several kilovolts were applied to the gap. In this case, the current through the gap was the value of kiloampere units. It is shown that a necessary condition for the discharge is the presence of gas cavities in the electrolyte. The stages of discharge development at voltage applied to the gap exceeding the threshold value (at which plasma occurs in gas cavities) are studied. The influence of the processes of occurrence and decay of gas cavities in the solution, as well as plasma in the cavities on the shape and value of the discharge current is analyzed.
