Breakdown of gaseous dielectrics at non-isothermic heating up to 3600 K
Quantitative data on breakdown voltages of non-isothermically heated inert gases at temperatures up to 3600 K are obtained. Existence of polarity effect of breakdown voltages U/sub br/ in uniform electric field at temperatures more than /spl sim/1700 K is established. At cathode heating up to specified temperatures breakdown voltages sharply decrease comparing with U/sub br/ at positive polarity of a heating electrode up to tens and units of volts because of increase of current of thermal electron emission. At anode heating breakdown voltages are determined by pattern or temperature field between electrodes. With this Paschen's law is used for evaluation of insulation properties of non-isothermically heated gases up to 3600 K temperatures.
