    Abstract: A disconnect switch assembly includes first and second disconnect switches with each of the first and second disconnect switch including a housing, a fixed main contact in the housing, and a movable main contact in the housing in cooperating alignment with the fixed main contact. Each of the movable main contacts is coupled to a (common) first actuator. A second actuator is coupled to the housing of the first disconnect switch and a third actuator is coupled to the housing of the second disconnect switch. The first actuator is configured to concurrently apply first and second motive forces (in opposing but in-line directions) to the movable contacts of the first and second disconnect switches. The second and third actuators are configured to apply a motive force to the housings that is in a direction opposing a respective motive force applied by the first actuator to the movable main contacts.

    Abstract: A circuit breaker includes a vacuum interrupter having a closed position and an open position. The circuit breaker includes a linkage operatively coupled to and extending from the vacuum interrupter and a high-speed actuator operatively connected to the linkage. The high-speed actuator is operable to move the linkage by a repulsion force and cause the vacuum interrupter to move to the open position. The circuit breaker includes a decelerator with an integrated latch assembly operatively coupled to the high-speed actuator. The decelerator decelerates the repulsion force of the high-speed actuator and latches the actuator with the integrated latch assembly to maintain the vacuum interrupter in the open position.

    Abstract: A vacuum interrupter including a first movable contact and electrode contained within a vacuum chamber, a second movable contact and electrode contained within the vacuum chamber, a first actuator operably coupled to the first movable contact, and a second actuator operably coupled to the second movable contact. The vacuum interrupter also includes a first bellows and first bellows plate operably coupled to the first movable electrode, as well as a second bellows and second bellows plate operably coupled to the second movable electrode. Additionally, the vacuum interrupter includes a first pressure chamber located between the first actuator and the vacuum chamber, and a second pressure chamber located between the second actuator and the vacuum chamber.

    Abstract: A circuit breaker includes a compact pole unit with an encapsulated body having ring(s) and conducting terminals that each extend from the encapsulated body. The body includes a vacuum interrupter and a coupler assembly that may be integrated into the pole unit. The coupler assembly includes a contact spring positioned an end of the compact pole unit, as well as a plunger that may be biased by the contact spring. The circuit breaker also includes an actuator positioned at the end of the pole unit that is opposite the coupler assembly. The circuit breaker also may include a second actuator that is will be connected to the contact spring of the coupler assembly via the plunger, and if so the breaker may be operated via either actuator.

    Abstract: A hybrid circuit interrupter can be used for medium voltage direct current applications, among other applications. The circuit breaker includes a vacuum circuit interrupter and an electronic power interrupter that are electrically connected in parallel. The vacuum circuit interrupter is normally closed and the electronic power interrupter is normally off, so that current passes through the vacuum circuit interrupter in a non-interrupt mode. When an interrupt condition is detected, the electronic interrupter will turn on, and current will pass through the electronic interrupter as the vacuum interrupter is opened. A current injector may draw current from the vacuum interrupter to the electronic power interrupter. An isolation switch may maintain the system in a non-conducting state when interruption is complete.
