GB/Z 43036-2023 Rotating electrical machines—Measurement of stator end-winding vibration at form-wound windings

Scope

This document specifies unified guidelines for measuring and reporting the end vibration of stator windings during operation and shutdown of motors. It includes:
——Defines terms for measuring, analyzing, and evaluating the end vibration of stator windings and related structural dynamics;
——Provides guidance for offline measurement of dynamic characteristics/structural characteristics and online measurement of end vibration of stator windings;
——Describes the use and installation methods of equipment for detecting end vibration of windings;
——Establishes general principles for reporting detection results;
——Describes the theoretical background of end vibration of stator windings.
This document is applicable to:
——Three-phase synchronous generators with a rated output of 150 MVA or more and driven by steam turbines or gas turbines;
——Three-phase direct grid-connected synchronous motors with a rated output of 30 MW or more.
This document only describes the measurement procedures for 2-pole and 4-pole motors. For motors with a rated output lower than that specified in this document, the supply and demand sides can reach a consensus on whether to adopt the measurement methods described in this document.
