IMPROVED COMPRESSED-GAS CIRCUIT-INTERRUPTERS OF THE PUFFER-TYPE HAVING IMPROVED SUPPORTING, SHIELDING AND ASSEMBLY FEATURES ABSTRACT OF THE DISCLOSURE An improved compressed-gas puffer-type circuit- interrupter is provided having improved supporting, shield- ing and assembly features for making ready provision for a separate bench subassembly of the gas-interrupter module, and enabling its ready application to a grounded metallic tank-type of circuit-interrupter, or, alternatively, to gas- insulated transmission-line equipment, as desired. Improved supporting features involve the utiliza- tion of a pair of upstanding side-insulating supporting shields, which substantially solely support the upper rela- tively-stationary contact and shielding assembly, apart from any support needed by the upper terminal-bushing, when used. Additionally, the invention comprises improved rod guiding features for the movable operating cylinder, improved shield- ing structure on both the stationary and movable contact structures and improved capacitor-tube mounting-assembly arrangements, an improved lower metallic base-support, having a shielding portion, which shields the relatively- sharp-cornered hardware features, such as the movable- contact guiding stem, reducing the electrical gradient, employing tubular shielding structures adjacent the central heavy supporting plate for relieving the electrostatic field, and employing, additionally, an improved upper electrostatic shielding arrangement, easily attached and disassembled by a simplified spring-clip assembly. An additional feature of the invention is the use of a spherical bearing located at the upper end of the -1- insulating pull-rod assembly, or operating-rod assembly to compensate for inaccuracies in manufacture, and improving the general assembly features adapting the modules for bench- assembly inspection.
