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.
A high-voltage circuit-interrupting assemblage comprising an upstanding supporting columnar structure; a first horizontally-extending supporting structure secured to, and supported by, said upstanding supporting columnar structure, said first horizontally-extending supporting structure having disposed therein a first common operating mechanism; a pair of second horizontally-extending supporting structures one each of which is secured to each end of said first horizontally-extending supporting structure, each of said second supporting structures having disposed therein a second common operating mechanism operatively connected to said first common operating mechanism such that said first and second operating mechanism operate simultaneously; a first hollow leg secured to each second supporting structure disposed generally parallel to said upstanding supporting columnar structure and a second hollow leg secured to each second supporting structure disposed along the axis of said first horizontally-extending supporting structure; an interrupting unit disposed in each of said first and second hollow legs, said interrupting units being operatively connected to said second common operating mechanisms and effecting simultaneous opening and closing of all of said interrupting units; and means for connecting said interrupting units in electrical series.
