SWITCHING METHOD AND DEVICE FOR SWITCHING Russian patent published in 2017 - IPC H01H33/02 

FIELD: electricity.

SUBSTANCE: switching device with a first contact side (6) has a first contact member (12), rated current and the first contact member (11) of the electric arc is moved relative to the second contact side (7) having a second contact member (13) of an electric arc and a second the contact member (14) the nominal current. During the switching process, the first contact member (11) of an electric arc moved by the motion profile and a first contact member (12) the nominal current is driven by the motion profile and motion profiles of the first contact member (11) of the electric arc and the first contact member (12 ) nominal current different from each other, and a second contact member (13) of an electric arc moved by the motion profile and a second contact member (14) the nominal current is driven by the motion profile and motion profiles of the second contact element (13) of the electric arc and a second contact element (14) the nominal current different from each other.

EFFECT: increase of power switching devices.
