Abstract
A switching device arrangement has a first contact set and a second contact set. The first contact set includes a first electric arc contact element and a first nominal current contact element. The first nominal current contact element can be moved relative to the first electric arc contact element. A first transmission is introduced in a kinematic chain in order to generate a relative movement of the first nominal current contact element and the first electric arc contact element. The first transmission is operationally connected between a stationary counter bearing and the first electric arc contact piece.
Claims19
A switching device arrangement, comprising:
- a first contact set and a second contact set, said first contact set being disposed for movement relative to said second contact set in order to produce a switching contact between respective contacts;
- said first contact set having an arcing contact piece and a nominal current contact piece movably disposed relative to one another;
- a kinematic chain connected to said nominal current contact piece configured to impress a movement onto said nominal current contact piece;
- a stationary counter bearing;
- and
- a gearing forming an operative connection between said stationary counter bearing and said arcing contact piece, wherein a relative movement is effected between said nominal current contact piece and said arcing contact piece via said gearing;
- said stationary counter bearing being coupled to said gearing via a slotted guide path.
