IEC 60034-18-31:2012描述了用于交流中的绝缘系统分类的热耐久性测试程序。或者华盛顿。具有间接冷却和成形绕组的旋转电机。这些测试程序旨在比较导体和接地之间的主壁绝缘的耐热性能，如果线圈或棒的设计需要，则比较匝间绝缘的耐热性能。与上一版相比的主要技术变化包括:-为成形绕组绝缘系统的热老化建立一致的标准化平台所需的测试方法和子循环的定义。-基于置信区间建立热寿命曲线的建议。-在可行范围内，对热等级的特定要求进行候选系统和参考系统性能的比较。关键词:旋转机械,绝缘系统

IEC 60034-18-31:2012 describes thermal endurance test procedures for classification of insulation systems used in a.c. or d.c. rotating electrical machines with indirect cooling and form-wound windings. These test procedures are intended to compare the thermal endurance performance of the mainwall insulation between conductor(s) and ground and, where required by the design of the coil or bar, the insulation between the turns. The main technical changes with regard to the previous edition include:
- Definition of the test method and sub-cycles required to establish a consistent standardized platform for thermal ageing of insulation systems for form-wound windings.
- Recommendations for establishing a thermal life curve based on confidence intervals.
- Comparison of candidate and reference system performance for specific requirements of thermal class, within feasible limits.Keywords: rotating machinery, insulation systems
