Abstract
An electrical switchgear has a first switching contact piece and a second switching contact piece. The two switching contact pieces can be moved relative to one another by way of a kinematic chain. The kinematic chain has an axially movable drive element, which is guided in a guide element. A first pin is guided in a first gate and defines the trajectory of the drive element in the guide element.
Claims13
A switchgear, comprising:
- a first switching contact piece movably mounted relative to a second switching contact piece;
- a kinematic chain for moving said first switching contact piece relative to said second switching contact piece, said kinematic chain including an axially displaceable drive element arranged as a piston guided on a guide element configured as a cylinder, said drive element and said guide element configured to be mutually relatively displaceable;
- said guide element being formed with a first gate;
- and
- a first pin in said first gate of said guide element determining a movement path of said drive element.

A switchgear, comprising:
- a plurality of switching poles, each switching pole comprising:
- a first switching contact piece movably mounted relative to a second switching contact piece;
- a kinematic chain for moving said first switching contact piece relative to said second switching contact piece, said kinematic chain including an axially displaceable drive element guided at a guide element;
- said guide element being formed with a first gate;
- a first pin in said first gate of said guide element determining a movement path of said drive element;
- and
- each axially displaceable drive element of a respective switching pole of said plurality of switching poles being fixed in a movement path in the respective first gate of the respective guide element via the respective first pin, wherein said axially displaceable drive elements of said plurality of switching poles are attached to a common cross-arm of said kinematic chains.
