    摘要： 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.

    摘要： An on-load tap changer is provided having a plurality of modules, each of which is operable to change taps in a winding of a transformer. A transmission shaft is connected to the modules and is operable upon rotation to effectuate tap changes in the windings. A servo motor rotates the transmission shaft. The servo motor includes a feedback device operable to generate a feedback signal containing information relating to the position of the motor shaft. A servo drive is connected to the servo motor to receive the feedback signal. The servo drive uses the feedback signal to determine and store a total angular displacement of the motor shaft. The servo drive uses the feedback signal and the total angular displacement of the motor shaft to control the operation of the servo motor.

    摘要： An on-load tap changer is provided having a plurality of modules, each of which is operable to change taps in a transformer winding. The tap changer includes a motor connected to rotate at least one shaft. The at least one shaft is connected to the tap change modules and is operable upon rotation to cause the tap change modules to each perform a sequence of operations that effectuate a tap change. A multi-turn absolute encoder is connected to the at least one shaft. A monitoring system is connected to the encoder and is operable to determine from the position of the at least one shaft where the tap change modules are in the sequence of operations.

    摘要： An on-load tap changer is provided having a vacuum interrupter actuatable by a shaft. A movable shuttle is connected to an impact mass by springs such that the impact mass tends to follow the shuttle when the shuttle moves. A pawl assembly is operable to hold and then release the impact mass when the shuttle starts moving. The holding of the impact mass when the shuttle starts to move causes the springs to store both a compression force and a tension force, which are released when the impact mass is released.
