ABSTRACT:
A simplified-type of multi-phase compressed-gas circuit-interrupter installation is provided in which costly and complicated I-beam base structures are eliminated, and the low-pressure gas-reservoir tank is so used and located as to provide a lower main support for the circuit-breaker installation. In addition, the high-pressure gas-reservoir tank is so used and located in such a manner that its main supporting brackets become a main support for the circuit-breaker assembly.
The construction is such that a simplified support is provided having the several component parts of the installation so arranged as to be readily accessible for servicing, and arranged together in a new combination for a resultant compact easily maintained arrangement.
