Abstract
An improved modular, puffer-type circuit-interrupting unit is provided capable of its own independent support, and adaptable for use, either as a singular modular unit, or when used with a plurality of similar units, constituting a conjointly-acting group of serially related puffer-units suitable for the higher-voltage applications. The modular puffer-unit of the instant invention is capable of independent support, and is adaptable for very simple straight-line actuating movement, for not only causing contact separation, but also a simultaneous compression of the utilized gas to a pressurized state for gas ejection into the established arc for rapid arc extinction thereof. A novel feature of the instant invention is the utilization of a side insulating support baffle plate, which not only provides the desirable independent support for the stationary contact structure of the modular puffer-unit, but, additionally, serves as a baffle plate to prevent the lateral dispersion of the emanated hot arc gases from reaching the side tank wall, and thereby causing voltage flash-over.
