“…Электроразрядные установки могут эксплуатироваться в разнообразных условиях, которые диктуются особенностями применения электроразрядных технологий [15]. Это разнообразие условий оказывает влияние на протекание процессов во время предпробойной стадии.…”

“…Данная тематика рассматривалась в работах ученых разных стран мира [11,12,[15][16][17][18]. Так, в работе [16] авторами отмечается, что необходимо разделять понятия «зарядное напряжение» и «напряжение пробоя», особенно это важно для электроразрядных технологий, в которых основным действующим фактором является волна давления.…”

“…Влиянию величины гидростатического давления на предпробойные характеристики было посвящено сразу несколько работ [11,15,17,18]. Так, в работе [11] авторами отмечается, что повышение гидростатического давления приводит к увеличению времени предпробойной стадии.…”

“…Дальнейшее увеличение удельной электропроводности не приводило к изменению длительности предпробойной стадии. В [15] отмечалось уменьшение напряжения пробоя с повышением электропроводности рабочей жидкости, что согласуется с результатами, представленными в [12]. Также в работе [15] В экспериментах использовалась электродная система типа острие-плоскость с анодом радиусом 2 мм и геометрией его конечной части в виде полусферы.…”

This work deals with the influence of the parameters of the working fluid (hydrostatic pressure, temperature, electrical conductivity) and the geometry of the electrode system (the length of the interelectrode gap and the uninsulated part of the anode) on the pre-breakdown characteristics of an electric discharge in a liquid aqueous electrolyte (breakdown voltage and breakdown delay time) and the minimum charging voltage, which provides a stable high-voltage breakdown of the interelectrode gap. Studies have shown that an increase in the hydrostatic pressure leads to an increase in most of the studied characteristics. At the same time, an increase in the specific electrical conductivity and temperature was observed to lead to their decrease. At the same time, it was suggested that the effect of temperature on the pre-breakdown characteristics is associated with a change in the specific electrical conductivity of the working fluid during its heating. The data obtained showed no effect of the length of the interelectrode gap on the breakdown voltage and its breakdown delay time, as well as the minimum charging voltage. The results of the experimental studies made it possible to develop a criterion for determining the charging voltage, which provides a stable high-voltage breakdown of the water interelectrode gap. Its experimental verification has shown that it can be applied to the design of electric discharge equipment and to the choice of technological modes of operation in the specified range of parameters.

It is necessary to find innovative ways to improve the environmental performance of production processes and products. The technology of extracting valuable components from raw materials of plant origin is often used in technological processes of the food, pharmaceutical, chemical and other industries. Extraction is the most energy intensive step. The factors contributing to the extraction of humic acids from plant substrates under the action of electric discharge were studied. The purpose of the work was to study the efficiency of humic acids extraction from the biosubstrate under the action of electric discharges. The physical experiment showed that the main factor influencing the intensity of extraction is the degree of grinding of the solid phase of the biosubstrate-water suspension. The efficiency of electric discharge grinding depends on the pressure amplitude at the distance of the inner radius of the chamber and the number of discharge pulses. It was established that the number of chemical reagents (alkalis), usually used in the process of extracting humic acids from peat, can be reduced many times due to the appearance of radicals and peroxide compounds in the peat-water suspension resulting from the action of an electric discharge. The prospects of the non-thermal electric discharge method of intensification of the extraction of humic acids from biosubstrates were determined.
