Abstract
A generally cross-shaped, or 'T'-shaped circuit-interrupter assemblage is provided having three outwardly radiating supporting arms, or members, within each of which is disposed a puffer-type compressed-gas circuit-interrupting unit. Common contact-operating means are provided at the common point of intersection of the three arms, or legs, so that simultaneous operation of the three puffer-type interrupters is accomplished. The electrical circuit passes serially through each of the three puffer-interrupting structures to thereby provide a high-voltage circuit-interrupter adaptable for voltages of the order of 345 KV, for example. An additional feature of the present invention is the provision of a common rotatable operating disc having pivotally connected thereto, adjacent its outer periphery, floating-connecting link structure, each of the three floating links being pivotally connected to the respective movable contact-operating rod of each of the three puffer-type interrupting units. An additional operating, or 'pull' rod connected adjacent the periphery of the common rotatable operating disc acts as a common pull-rod extending to ground potential to thereby enable the operation of said disc at high voltage. An additional feature of the present invention is the provision of a closing resistance, when desired, for each of the three puffer-type circuit-interrupters. Still a further feature of the invention is the provision of two such cross-shaped, or 'T'-shaped interrupting structures for the provision of six serially-related breaks for extremely high voltages, such as 550 KV or 765 KV, for example.
