STUDY OF ARC CONSTRICTORS FOR ELECTRODE ISOLATION,
Abstract
The principles of self-magnetic compression and magnetic pumping in a mechanically constricted arc column were used in an attempt to isolate the cathode region from the remainder of a d-c arc at one atmosphere pressure. Two modes of operation were studied. In the first mode, the constrictor orifice was used as a straight nozzle, and the arc characteristics were recorded for argon mass flows from 0.409 to 1.12 g/s through the nozzle, arc lengths of 8.0 to 11.0 cm, and currents of 40 to 90 amps. A spectrographic analysis made of the arc below the constrictor orifice at one mass flow (0.409 g/s) indicated a backflow of air into the cathode chamber. The second mode of operamployed the principles first men tioned in operating the device as an argon arc below the constrictor and as an air arc above the constrictor. (Author)
