An improved multi-phase compressed-gas circuit-breaker installation is provided having the three or more circuit-breaker assemblies mounted upon a horizontally-extending rigid frame structure, with the high-pressure and low-pressure gas-reservoir tanks disposed close to the ground, and having the circuit-breaker assemblies extending upwardly in spaced lateral horizontal relationship. Pressurized pipes, or conduits connect to the circuit-breaker assemblies, the pressurized pipes containing, of course, the internal high-voltage power-conductors at the centers of the pressurized pipes, as well known by those skilled in the high-voltage power-transmission art of the pressurized gas-insulated type. Longitudinally-extending contact-operating linkage is provided lengthwise along the supporting frame structure, in an easily accessible location, and the control compartments and gas-compressor units are disposed in an advantageous relationship and location with regard to the gas-storage tanks, which leads to easy servicing and maintenance.

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.

An improved multiphase compressed-gas circuit-interrupter installation is provided having compact, serviceable and inexpensive operating arrangements with an improved gas-leakage detection arrangement and system for detecting a loss of high-pressure gas in each of the multiphase circuit-breaker modules to the exclusion of the other adjacent circuit-breaker phase modules. An improved operating-linkage rod-assembly is provided extending across the front of the circuit-breaker installation, and readily available for easy servicing and adjustment, so that synchronism of the control valves in the several phase-units, or pole-units may be achieved.
