Patent ID: 7705262

Claim:
An alternator disconnector circuit-breaker comprising: a first switch having a first pair of contacts that are mounted to move relative to each other in translation along a first axis; a circuit-breaker second switch having a second pair of contacts that are mounted to move relative to each other in translation along a second axis, the second switch electrically connected in parallel with the first switch; a disconnector third switch having a third pair of contacts that are mounted to move relative to each other; and synchronization means making contacts of the first switch to separate before the contacts of the second switch separate, wherein the contacts of the second switch separate before the third contacts separate fully; said alternator disconnector circuit-breaker being characterized in that the synchronization means are actuated by a servomotor which actuates the synchronization means to obtain a first opening speed at which the first pair of contacts begin to separate around a first half of an opening stroke, the servomotor and the synchronization means to obtain a second opening speed at which the first pair of contacts continue to open around a second half of the opening stroke, wherein the first opening speed is approximately three times greater than the second opening speed.
