标准摘要
[中文适用范围]: 本部分的 IEC 60034 规定了特定电气机器在指定条件下(与任何负载或原动机解耦)的工厂验收振动试验程序和振动限值。它适用于轴高 56 mm 及以上、额定输出最高至 50 MW、运行转速从 120 min⁻¹ 至 15 000 min⁻¹ 的直流电机和三相交流电机。本文件不适用于现场安装的机器、三相换向器电机、单相电机、在单相系统上运行的三相电机、垂直水轮发电机、功率超过 20 MW 的汽轮发电机以及具有磁轴承或串励绕组特征的电机。 [外文原描述]: IEC 60034-14:2018 specifies the factory acceptance vibration test procedures and vibration limits for certain electrical machines under specified conditions, when uncoupled from any load or prime mover. It is applicable to DC and three-phase AC machines, with shaft heights 56 mm and higher and a rated output up to 50 MW, at operational speeds from 120 min–1 up to and including 15 000 min–1. This new edition includes the following significant technical changes with respect to the previous edition: - Improved explanation of the definition “free suspension”. - Addition of an alternative method of rigid mount - Definition of an improved option for shaft key.
