  • Tap changer
    Patent number: 9401249
    Abstract: An on-load tap changer is provided and includes a plurality of modules disposed in an interior space of a tank and arranged in a side-by-side manner. Each module has a bypass switch assembly and a vacuum interrupter assembly mounted to a first side of a board. The bypass switch assembly is actuated by rotation of a bypass cam and the vacuum interrupter assembly is actuated by rotation of an interrupter cam. A transmission system rotates the bypass cam and the interrupter cam. The transmission system is mounted on a second side of the board.

  • Tap changer having a vacuum interrupter assembly with an improved damper
    Patent number: 9136055
    Abstract: An on-load tap changer is provided having a vacuum interrupter that is actuated by a shaft of an actuation assembly. A damper dampens the movement of the shaft. The damper provides more dampening when the shaft is closing the vacuum interrupter than when the shaft is opening the vacuum interrupter. The damper includes a housing at least partially defining an interior chamber into which the shaft extends. A piston with openings extending therethrough is disposed in the interior chamber and is secured to the shaft so as to be movable therewith. A blocking structure is operable to block the openings in the piston when the shaft is closing the vacuum interrupter and to un-block the openings in the piston when the shaft is opening the vacuum interrupter.
