COMMUTATOR Russian patent published in 1999 - IPC

FIELD: automation and switch-board equipment. SUBSTANCE: device has commutation units, which contain make circuit relays and are connected to each other in specific way. Goal of invention is achieved by design of each commutation unit as integral no-deadlock commutation system for six input-output ports. Each commutation cell is represented as cube which side corresponds to one input-output port. Combination of all cubes provides single cube with specific connection between input-output ports in inner sides of cubes, while input-output ports on outer sides of cubes of external layer of global cube provide input-output ports of device. EFFECT: decreased number of commutation units for designing integral no-deadlock switch-board systems with high input capacity. 7 dwg
