Abstract
Abstract An explosive circuit-breaker comprising an insulation housing with a hollow conductor passing inside and insulated from said housing, an explosive charge disposed inside said conductor and a detonator, said circuit-breaker differing from the existing ones in that the destructible section of the conductor is made in the form of a corrugated tube and the housing is made essentially hermetic with an evacuated inner space.

An explosive circuit-breaker comprising, in combination: a housing made from a strong material, a hollow conductor passing inside and insulated from said housing, an explosive charge disposed inside said conductor within its section located inside said housing to break said conductor and a detonator to activate the explosive charge, wherein the destructible section of the conductor is made in the form of a corrugated tube and the insulation housing is essentially hermetic with an evacuated inner space, the residual pressure P (mm Hg) and the dimensions of the housing and of the conductor complying with the following relationships: P < OR = 0.05/(R1-R2) and R1 > OR = 3R2, where R1 - inner radius of the insulation housing, centimeters; R2 - outer radius of the destructible section of the conductor, centimeters.
