Abstract

Supercritical fluids (SCFs), characterized by a high pressure and high density, combine the advantages of gasses and liquids: high ability of mass transfer and high heat transfer. SCFs have a high potential as an electrical switching medium owing to their high breakdown strength, quick self healing, no bubble formation, high heat capacity, high heat conductivity, low viscosity, and low impact to the environment. In this work the thermodynamic characteristics of supercritical fluids are introduced. An experimental analysis of electrical breakdown phenomena of a supercritical plasma switch with pressure up to 180 bar is presented, focusing on the breakdown voltage variation as a function of the fluid pressure, gap width of the electrodes and fluid flow rate through the gap. A new design of a supercritical switch, with flexible gap width, flushing velocity, and repetitive voltage source is introduced.
