Abstract (en)
[origin: EP0612086A1] In the case of a drive for an electrical power circuit breaker having a cam disc and a transmission element (11), which can be driven between a first position and a second position of the cam disc (10), as well as having a braking element (3) which decelerates the transmission element (11), the cam disc (10) is formed in such a manner that the differential quotient (f') of the distance travelled by the transmission element (11) and the rotation angle of the cam disc (10), considered as a function of the rotation angle of the cam disc (10), is at a maximum (18) in the initial range of movement transmission between the cam disc (10) and the transmission element (11). In consequence, the transmission element (11) is accelerated rapidly, followed by slow braking. <IMAGE>
