A power plant has a generator that is cooled by hydrogen gas. The power plant has a terminal compartment for housing stator terminals of the generator and conductor connections of a main bus taking electrical power away from the power plant. The power plant has a generator auxiliary equipment compartment that is distinct from the terminal compartment. The generator auxiliary equipment compartment receives tap connections that draw power from the main bus. The main bus comprises isolated phase bus duct, one for each phase. Electrically insulating sealing bushings are located in each phase of the isolated phase bus duct between the connections with the stator terminals and the tap connections to seal against the escape of hydrogen gas from the terminal compartment into the generator auxiliary equipment compartment.

Isolated generator equipment compartment

A switch has a first electrical terminal, a second electrical terminal spaced from the first electrical terminal and an elongate conductive switch blade for bridging the terminals. The switch blade has a first end portion pivotally connected with the first electrical terminal for movement of the switch blade between open and closed positions. The switch blade has a second end portion positioned adjacent the second electrical terminal when in the closed position. A plurality of elongate fingers are secured by spring loading to the second end portion of the switch blade. The fingers are arranged adjacent to each other along opposing sides of the second end portion to form an open jaw structure that extends from the second end portion of the switch blade and makes wiping electrical contact with the second electrical terminal as the switch blade is moved into the closed position.
