标准摘要
[中文适用范围]： IEC 60034的这一部分规定了某些电机在特定条件下的工厂验收振动测试程序和振动限值，当电机与任何负载或原动机解耦时。 它适用于直流和三相交流电机，轴高56毫米及以上，额定输出功率高达50兆瓦，运行速度从120转/分钟到15000转/分钟（包括）。 本文件不适用于现场安装的电机、三相换向器电机、单相电机、单相系统上运行的三相电机、垂直水力发电机、大于20兆瓦的涡轮发电机以及带有磁轴承或串绕电机的电机。 注：对于现场测量的电机，请参考ISO 20816、ISO 10816和ISO 7919的适用部分。 [外文原描述]： IEC 60034-14:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
