Gas cooled electrical equipment for distribution systems

Claim 1

IN AN ELECTRIC POWER DISTRIBUTION SYSTEM, THE COMBINATION COMPRISING, A TRANSFORMER HAVING A PRIMARY WINDING, A CIRCUIT INTERUPTER HAVING AT LEAST TWO POLES, ONE OF SAID POLES BEING CONNECTED TO SAID PRIMARY WINDING, A HIGH VOLTAGE SUPPLY CONDUCTOR CONNECTED TO ANOTHER POLE OF SAID CIRCUIT INTERRUPTER, AND A GAS-FILLED HOUSING SURROUNDING SAID TRANSFORMER AND CIRCUIT INTERUPTER, SAID HOUSING HAVING A VERTICAL DIMENSION SUBSTANTIALLY GREATER THAN THE VERTICAL DIMENSION OF SAID TRANSFORMER AND A HORIZONTAL DIMENSION SUBSTANTIALLY GREATER THAN THE HORIZONTAL DIMENSION OF SAID TRANSFORMER, SAID TRANSFORMER BEING DIPOSED WITHIN SAID HOUSING ADJACENT THE LOWER EXTREMITY OF THE VERTICAL DIMENSION OF SAID HOUSING AND NEAR ONE EXTREMITY OF THE HORIZONTAL DIMENSION THEREOF, AND SAID CIRCUIT INTERRUPTER BEING DISPOSED WITHIN SAID HOUSING NEAR THE OPPOSITE EXTREMITIES OF SAID VERTICAL AND HORIZONTAL DIMENSIONS, WHEREBY GAS CONVECTION CURRENTS INDUCED BY HEAT GENERATED IN SAID TRANSFORMER HAVE A CIRCULATION PATH DOWNWARDLY PAST SAID CIRCUIT INTERRUPTER AND UPWARDLY PAST SAID TRANSFORMER, IN SUCCESSION, TO COOL SAID TRANSFORMER.
