Physical Aspects of Diaphragm Discharge Creation Using Constant DC High Voltage in Electrolyte Solution

Popis výsledku v původním jazyce

This paper presents new results obtained from the investigation of the breakdown moment of diaphragm discharge generated using constant DC voltage in water solutions of two electrolytes (NaCl and NaNO_3). Electrical discharge was created in an orifice (initial diameter of 0.2 mm) in dielectric diaphragm (thickness of 0.25 mm) separating two electrode spaces. Both dynamic and static VA characteristics were recorded and subsequently, breakdown parameters were determined as a function of solution conductivity (adjusted by electrolyte concentration in the range of 300-1300 microS/cm). Obtained results revealed a significant decrease of breakdown voltage (from 1350 to 880 V) and resistance with the increasing solution conductivity. On the other hand, discharge power and current at breakdown moment was enhanced by the increasing conductivity (from 40 to 100 mA). This effect was similar in both tested electrolytes. Discharge ignition in water was related with bubble creation in the orifice, a
