説明

Measurements were made of the sum of cathode-fall and anode-fall voltages, i.e. electrode fall voltage Vfall for SF6 arc at a pressure of 0.1 MPa in wide current range from 10 to 20000A. The SF6 arc was burned between electrodes of copper-tungsten, copper, iron, titanium, carbon and tungsten. For each electrode, Vfall at a given current was estimated as arc voltage at zero gap length between the electrodes, which was extrapolated from arc voltages measured in short gaps with various lengths below 3mm. The electrode fall voltage Vfall proved to be 17.5, 17.5, 17.5, 17.3, 15.2 and 13.8V for the Cu-W, Cu, Fe, Ti, C and W electrodes, respectively. The electrode fall voltage Vfall was affected by the electrode material. It was also found that the electrode fall voltage at a given electrode was independent of current in the above range.
