20060151437 - Monolithic stationary conductor and current limiting power switch incorporating same: A current limiting power switch has a monolithic stationary conductor with a conductor section that mounts fixed contacts that engage moving contacts on moving contact fingers to form a reverse current loop with the contacts closed. A terminal section projects transversely from one end of the conductor section and an...

20060151438 - Method of current interruption using puffer type gas circuit breaker with combined-action of cylinder and piston: A puffer type gas circuit breaker has a piston, which is connected with a center shaft via a link mechanism. At an initial stage of an interruption operation, the link mechanism drives a puffer cylinder and the piston both in an interruption direction while maintaining an almost constant distance therebetween....

20060151439 - Circuit breaker with improved arc extinction system: An improved circuit breaker includes an arc extinction system having one or more insulators that generates a desirable gas in the presence of an arc. The exemplary circuit breaker includes gas-generating insulators disposed at three sides of a stationary contact and an arc chute at a fourth side of the...
