Abstract
Abstract An explosion type circuit breaker incorporating a hollow current-carrying bus containing an explosive charge and detonator characterized in that the current-carrying bus is provided with dielectric sheathings covering outer and inner surfaces of the hollow current-carrying bus, the dielectric sheathing covering the inner surface of the current-carrying bus having an annular groove and the explosive charge having an annular cumulative recess lined with a dielectric and facing the above-mentioned annular groove of the dielectric sheathing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
An explosive type electric power circuit breaker comprising: a hollow current-carrying tubular bus; outeR and inner dielectric sheathings disposed respectively on the outer and inner surfaces of said hollow current-carrying tubular bus; an annular groove formed on the periphery of said inner dielectric sheathing; an explosive charge disposed inside said hollow current-carrying tubular bus, said explosive charge being shaped so as to have an annular notch-shaped recess positioned opposite said annular groove in said inner dielectric sheathing; and a detonator means for igniting and exploding said explosive charge at a moment when the electric power circuit in said hollow current-carrying tubular bus is desired to be interrupted; said recess of said explosive charge directing the explosive force towards said annular groove of said tubular bus such that said bus bursts along a circumferential region adjacent of said annular groove so as to cause swift interruption of the electric power circuit.
Claim 2
Dependent Claim
150 words
An explosive type electric power circuit breaker comprising: a hollow current-carrying tubular bus; outeR and inner dielectric sheathings disposed respectively on the outer and inner surfaces of said hollow current-carrying tubular bus; an annular groove formed on the periphery of said inner dielectric sheathing; an explosive charge disposed inside said hollow current-carrying tubular bus, said explosive charge being shaped so as to have an annular notch-shaped recess positioned opposite said annular groove in said inner dielectric sheathing; and a detonator means for igniting and exploding said explosive charge at a moment when the electric power circuit in said hollow current-carrying tubular bus is desired to be interrupted; said recess of said explosive charge directing the explosive force towards said annular groove of said tubular bus such that said bus bursts along a circumferential region adjacent of said annular groove so as to cause swift interruption of the electric power circuit.
Claim 3
Dependent Claim
55 words
An explosive circuit breaker as claimed in claim 1, wherein said outer dielectric sheathing disposed along the outer suface of said hollow current-carrying tubular bus is provided with an annular groove positioned opposite the annular groove made in the said inner dielectric sheathing so as to facilitate a more effective interruption of the electric circuit.
Claim 4
Dependent Claim
53 words
An explosive circuit breaker as claimed in claim 1, wherein said annular notch-shaped recess is lined with a dielectric substance, whereby said dielectric lining serves to impinge violently against said current-carrying tubular bus so as to facilitate a more effective repturing thereof, when a circuit interruption is initiated by detonating said explosive charge.
