Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
The combination in a multi-pole high-power high-voltage circuit-interrupter assemblage having a plurality of pole-units ("A", "B", "C") each with its separable arcing contacts, adaptable for interrupting multi-phase high-voltage circuits of considerable amperage, of a single common operating mechanism at ground potential for simultaneously effecting the opening and closing operations of the several arcing contacts for all of the several pole-units, a mechanical interconnecting operating linkage positively connected between the individual pairs of separable arcing contacts of the several pole-units and said single common operating mechanism situated at ground potential, an independently-operated ball-release latching means (22) interposed in said positive interconnecting operating linkage (20, 34, 46) for at least one of said pole-units, means responsive to a fault condition existing in said one pole-unit to release said independently-operated ball-release latching means (22) to thereby trip the said one affected faulted pole-unit open independently of the condition of said single common operating mechanism at ground potential.
Claim 2
Dependent Claim
154 words
The combination in a multi-pole high-power high-voltage circuit-interrupter assemblage having a plurality of pole-units ("A", "B", "C") each with its separable arcing contacts, adaptable for interrupting multi-phase high-voltage circuits of considerable amperage, of a single common operating mechanism at ground potential for simultaneously effecting the opening and closing operations of the several arcing contacts for all of the several pole-units, a mechanical interconnecting operating linkage positively connected between the individual pairs of separable arcing contacts of the several pole-units and said single common operating mechanism situated at ground potential, an independently-operated ball-release latching means (22) interposed in said positive interconnecting operating linkage (20, 34, 46) for at least one of said pole-units, means responsive to a fault condition existing in said one pole-unit to release said independently-operated ball-release latching means (22) to thereby trip the said one affected faulted pole-unit open independently of the condition of said single common operating mechanism at ground potential.
Claim 3
Dependent Claim
38 words
The combination of claim 1, wherein the ball-release latching means includes an outer ball-retainer cage having a plurality of ball-recesses therein, an inner pneumatically-actuated ball-catch device, and said ball-catch device having a piston-face portion responsive to pressure conditions.
Claim 4
Dependent Claim
16 words
The combination of claim 2, wherein the ball-catch device is spring returned to its latching position.
Claim 5
Dependent Claim
23 words
The combination of claim 3, wherein an electrically-actuated solenoid-valve device admits or prevents gas pressure against said piston portion of the ball-catch member.
Claim 6
Dependent Claim
59 words
The combination of claim 1, wherein a ball-retainer cage (24) is positively secured to the operating mechanism (15) a thrust member (21) is secured to the movable contacts of the circuit-breaker and carry a movable ball-catch latching device (30) thereon having lost-motion, and spring means (31) being provided for biasing the ball-catch latching device (30) into a ball-latching position.
Claim 7
Dependent Claim
32 words
The combination according to claim 5, wherein an electrically-actuated solenoid valve (42) controls the admission of high-pressure gas through the thrust member and against the piston surface of the ball-catch member (30).
