MULTIPOLE INTERRUPTER UNIT, DISTRIBUTION SYSTEM OPERATING PROCESS, AND DISTRIBUTION SYSTEM Russian patent published in 2005 - IPC

FIELD: electrical engineering; medium-voltage distribution systems for main stations incorporating at least one multipole unit.

SUBSTANCE: proposed multipole interrupter unit has interrupter for each pole incorporating insulating bushing passed in direction formed by relatively parallel center lines of interrupters. Interrupters constitute integrated unit and are free to displace relative to external input and output contacts for opening the line. External input and output contacts include group of relatively parallel buses. There are means for translational motion of interrupters along main direction in parallel with their center lines for connection and disconnection of line. Center lines of mentioned interrupters are vertical and lie in central vertical plane perpendicular to mentioned buses.

EFFECT: improved design.
