IMPROVED TANK-TYPE COMPRESSED-GAS CIRCUIT-INTERRUPTER OF THE PUFFER TYPE HAVING IMPROVED ASSEMBLY FEATURES ABSTRACT OF THE DISCLOSURE An improved grounded-tank-type of compressed-gas circuit-interrupter is provided having improved assembly features for making provision for a separate subassembly of the gas-interrupter gas modules, with their actuating link- age affixed to a mounting support plate. Subsequently, as a subsequent separate assembly operation, the said mounting support-plate constitutes tile lower closure member of an upstanding metallic grounded outer tank assembly, which is dropped, as a final assembly operation, over the aforesaid subassembly and bolted thereto. Another feature of the instant invention includes the upper curved dome portion of the outer tank having a predetermined radius of curvature, with the two terminal- bushing flange-rings making flush attachment to the tank, and having the center-line of the two terminal-bushings being normal to the curvature of the upper curved dome portion. Thus, the divergence angle between the two ter- minal-bushings is predetermined in the proper manner, and ready assembly of the terminal-bushings is thereby achieved without the use of adaptors, or coupling ring members, as required heretofore. Preferably, the operating mechanism housing, together with its internally-located operating mechanism, is attached to the side of the outer upstanding metallic tank, and the mechanical interconnection between the operating mechanism and the previously-mentioned actuating linkage for the gas-modular units is readily made, without requiring -1- critical alignment, or accurate positioning of the several parts. Another feature of the invention is the use of a relatively-short, non-magnetic insert-strip extending be- tween the two aforesaid flange-rings for supporting the terminal-bushings, thereby minimizing concomitant eddy- current heating losses. Still another feature of the invention is the use of a suitable non-magnetic material, such as non-magnetic stainless steel, for example, for fabricating the upper dome portion of the grounded tank structure itself.
