Abstract
An arrangement for a high-voltage circuit breaker includes at least one movable electric contact piece of an interrupting unit. The at least one movable contact piece is disposed on a switch rod and the switch rod is movably mounted between an outer region and an inner region of the housing of the interrupting unit. The switch rod is guided in a solely linear manner in the arrangement. A method for driving the at least one movable electric contact piece includes using the switch rod to move the contact piece. The switch rod is moved in a solely linear manner along the longitudinal axis of the switch rod.
Claims19
An anti-twist assembly for a high-voltage circuit breaker, the anti-twist assembly comprising:
- an interrupter unit including at least one movable electric contact piece, said interrupter unit having a housing supported by a supporting foot;
- a switch rod being movably mounted with an exclusively linear guidance of said switch rod, said at least one movable contact piece being disposed on said switch rod;
- and
- an anti-twist mechanism including a switch rod foot connected to said switch rod and providing said linear guidance of said switch rod, said anti-twist mechanism including a body connected to said switch rod foot and being movable in a groove formed in said supporting foot.
A method for driving at least one movable electrical contact piece of a high-voltage circuit breaker, the method comprising the following steps:
- providing an interrupter unit having at least one movable contact piece and having a housing supported by a supporting foot;
- providing a switch rod having a longitudinal axis and being movably mounted with an exclusively linear guidance of the switch rod, the at least one movable contact piece being disposed on the switch rod;
- providing an anti-twist mechanism including a switch rod foot connected to the switch rod and providing the linear guidance of the switch rod, the anti-twist mechanism including a body connected to the switch rod foot and being movable in a groove formed in the supporting foot;
- and
- using the switch rod to move the at least one movable contact piece exclusively linearly along the longitudinal axis of the switch rod.
