ANORDNING AV STROMANSLUTNINGAR TILL EN TURBOGENERATOR

摘要

A stator conductor terminal assembly is located in a casing attached to the underside of the housing of a three-phase turbogenerator for leading out the phase windings of the stator coil heads. The assembly includes three liquid-cooled hollow conductors connected respectively at one end to corresponding hollow switching leads, the conductors extending from the switching leads in a first section vertically downward, thence in a second section directed horizontally for different distances, and then vertically downward in a third section through an elastic support carried by an insulating plate. The third sections of the hollow conductors pass outward through the bottom of the casing and terminate in polygon-shaped connection terminals. The casing also includes current transformers located below the insulating plate between the third sections of the hollow conductors. A somewhat similar arrangement of liquid-cooled hollow conductors is provided within the casing to establish the star-point terminal of the stator winding.
