MHD pinch interrupting switch for high currents

摘要

Switching apparatus for very high currents utilizes the magneto hydrodynamic pinch effect to interrupt a liquid metal column that occupies the gap between a pair of spaced conductors maintained apart by an insulating sleeve. The on/off condition of the switching apparatus is controlled by regulating the relationship between the fluid pressure within the sleeve and Pp, the MHD pinch pressure.
