47,901IMPROVED STRUCTURAL SUPPORTING ARRANGEMENTS FORA MULTI-BREAK LIVE-TANK CIRCUIT-BREAKERASSEMBLAGE HAVING IMPROVED VOLTAGE-DISTRIBUTIONCHARACTERISTICS BETWEEN THE SEVERAL SERIES BREAKSABSTRACT OF THE DISCLOSUREA multi-break, high-power, live-tank, circuit-interrupter assembly has improved inherent voltage-divi-sion characteristics by having upstanding supporting columnstructures disposed slantingly outward, in a diverging"V"-shaped relationship, or, alternatively, vertically-disposed in an inverted "U"-shaped relationship. A modi-fied mounting constitutes a generally inverted "U"-shapedsupporting construction, with the series multi-breaksdisposed at the upper horizontal side of the structure,that is disposed within the horiziontal "bight" portionof the inverted "U"-shaped supporting structure. Thisminimizes the effects of inherent parasitic capacitance,which tends to lead to unequal voltage distribution betweenthe several series breaks.
