ABSTRACT:
An internal combustion electrical circuit breaker comprising at least one: (a) insulating cylinder; (b) pair of electrical conductors penetrating the cylinder approximately perpendicular to its longitudinal axis at a distance from both cylinder's plane sides; (c) conducting hollow piston contacting the conductors and an insulating pipe at its open portion, which pipe extends within that axis and penetrates the cylinder's first plane side; (d) arcing chamber extending from that plane side to the conductors; (e) pair of arcing blades within the arcing chamber at a distance from the conductors, piston and pipe; (f) valves within the pipe and first plane side, communicating with the arcing chamber and hollow piston; (g) combustion chamber extending from the piston's closed portion to the cylinder's second plane side; and (h) ignition, gas injection and valve means within the plane side and communicating with the combustion chamber.
When igniting a fuel-oxygen mixture within the combustion chamber, the piston is propelled into the arcing chamber and onto the pipe therein, while the gases within hollow piston and arcing chamber blow across the sparks developing between conductors, piston and arcing blades. This circuit breaker is re-set by injecting compressed gas through the pipe, thereby forcing the piston into the combustion chamber and back onto the conductors, while expelling combustion products and injecting a combustible gas mixture, preferably a stoichiometric (1:2) oxygen/hydrogen mixture into that chamber, which is lined with a material suppressing heat damage and catalytic recombination of the gas mixture therein.
