GB/Z 43036-2023Rotating electrical machines - Measurement of stator end-winding vibration at form-wound windings (English PDF)

1 Scope

This document stipulates unified guidelines for measuring and reporting the vibration of the stator winding end when the motor is running and shut down. include.

--- Defines terms for measuring, analyzing and evaluating stator winding end vibration and related structural dynamics;

--- Provide guidance for offline measurement of dynamic characteristics/structural characteristics and online measurement of stator winding end vibration;

---Describes the use and installation method of winding end vibration detection equipment;

---Established general principles for reporting test results;

---Describes the theoretical background of stator winding end vibration.

This document applies to.

---Three-phase synchronous generators with a rated output of 150MVA and above and driven by steam turbines or gas turbines;

---Three-phase direct grid-connected synchronous motors with rated output of 30MW and above.

This document only describes the measurement procedures for 2-pole and 4-pole motors. For motors with ratings lower than those specified in this document, both supply and demand parties may

Reach consensus on whether to use the measurement methods in this document.
