Mechanical Characteristics of the Turbogenerator Stator Outhang at Various Options of Fixing at a Core End Zone

Abstract

The mechanical characteristics in a copper and isolation of the turbogenerator 300 MW stator winding under a nominal loading has been searched by a numeral method at the different variants of fixing in the core end zone. Distribution of a radial and axial movements and a mechanical tension in isolation on a length of an outhang bar under action of an elektrodynamic forces is received. Changes of the indicated above characteristics when weakened a fixing of an outhang bars in a stator end zone are estimated. The new advanced design of a fixing it at an exit from a core for minimization a moving of a turbogenerator stator outhan is offered. Refe rences 10, figures 3.
