Abstract
A quick-acting movable-column tripping device is provided as an optional feature of either circuit-interrupters, supported by upstanding insulating column structures, or, alternatively, in connection with circuit-interrupters having a serially-related disconnecting switchblade, providing a visible open-circuit gap, so that a minimum of time is utilized in a tripping operation of the circuit-interrupter. Otherwise, there would be a considerably-delayed action caused by the normal, or inherent lost-motion provided in the loose linkages, which normally are used to effect operative movement of the movable relatively massive supporting column structure. The quick-acting, accelerating tripping device of the present invention provides relative fast motion between the upstanding rotatable supporting column structure and a base-spindle device, the latter of which is operatively mechanically linked to the motor-operated mechanism, for example, of the switch structure, which may be relatively slow in operation.
