LOAD SWITCH OF STEP SWITCH Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: device has driving slides, which are mounted for continuous movement, being driven by driving shaft. In addition device has driven member, which actuates switching shaft. Goal of invention is achieved by switching insertion, which is mounted on switching shaft and carries cam disks for driving vacuum switches and mechanical commutation members. Depending on switching direction, i.e. linear movement of driving slides of power accumulator, switching insertion slides over switching shaft in upper or lower position, so that different cam disks are in use. This results in possibility to design asymmetrical circuits, which require identical sequence for moved or driven commutation members independently from switching direction. EFFECT: increased functional capabilities. 8 cl, 7 dwg
