Investigation of Relationship Between Vibration State of Core and Frame of Stator in Turbogenerators with Tangential Construction of Elastic Suspension

Abstract

Questions related to attempts to increase the efficiency of control of the vibration state of the stator in turbogenerators with tangential design of the elastic suspension of the core are discussed. Results of a theoretical study of the influence of the rigidity of the base supports of the frame of the turbogenerator and of features of the mounting of the active steel to the intermediate cradle on the vibratory state of the elements of the stator are discussed. Problems related to assessing the vibration state of the core on the basis of the level of vibration of the frame are considered. Measures to improve the procedure used to monitor the vibration and technical state of a stator are proposed.
