标准摘要
[中文适用范围]： 本部分IEC 60034适用于大型旋转电机，并建立了确定单独损耗的附加方法，以及补充IEC 60034-2-1的效率定义。当满载测试不切实际且导致更大的不确定性时，这些方法适用。 注：根据热量计量法进行的现场测试在满载条件下被认可。 具体描述的方法包括： - 校准机器法 - 减速法 - 热量计量法 - 永磁励磁同步电机的损耗求和法。 [外文原描述]： IEC 60034-2-2:2024 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034‑2‑1. These methods apply when full-load testing is not practical and results in a greater uncertainty. The specific methods described are: - Calibrated-machine method. - Retardation method. - Calorimetric method. - Summation of losses for permanent magnet excited synchronous machines. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition: - Layout and procedures aligned with IEC 60034-2-1 and IEC 60034-2-3. - Annex A added: an informative procedure for the summation of losses for large permanent-magnet excited synchronous machines.
