Abstract

The housing is constructed from two hollow metal cylinders (6, 7) clamped together on either side of a disc of insulating material (5). Terminals (13, 14) are clamped by bolts to the ends of the metal cylinders. Inside the cylinders is a conducting material such as mercury, sodium, caesium or a metal alloy (3), and provision is made for an expansion space, filled with an inert gas, such as nitrogen, and a small piston (8). A number of other components are included, such as iron shot, which disperse under the influence of a high electric current. The assembly has the effect of imposing a higher resistance to current flow for high flux densities than for low current flux densities.
