Abstract
An improved gas-heating means is provided for a multi-phase gas-type circuit-interrupter, all phases being supplied with high-pressure gas from a single high-pressure reservoir tank by suitable baffling means spaced longitudinally along the high-pressure reservoir tank, together with hot and cold inlet and outlet pipes leading into the separate upstanding circuit-breaker columns, or modules, controlling the individual phases, with the cold outlet pipe, preferably, extending downwardly toward the lower end of the high-pressure reservoir tank, and the hot inlet pipe located, preferably, at a higher elevational level than the cold outlet pipe, for thereby promoting proper heated gas circulation into the upstanding circuit-breaker modules.
