标准摘要
[中文适用范围]： IEC 60034 的这一部分定义了评估单相或多相交流电机定子/转子绕组绝缘系统的标准，这些电机承受重复脉冲电压，例如由脉冲宽度调制 (PWM) 转换器产生的电压，并且预计会经历和在使用期间承受局部放电活动。它规定了对代表性样本的电气资格测试，以验证是否适合与电压源转换器一起运行。它还描述了一个附加的分类系统，该系统定义了转换器供电条件下可靠性能的限制。尽管本文档涉及电压转换器，但人们认识到还有其他类型的转换器可以产生重复的脉冲电压。对于这些转换器，可以使用类似的测试方法。对于仅由电压转换器供电用于启动的旋转机器，可能不需要绝缘系统的鉴定，因此它们被排除在本文件之外。 [外文原描述]： IEC 60034-18-42:2017 defines criteria for assessing the insulation system of stator/rotor windings of single or polyphase AC machines which are subjected to repetitive impulse voltages, such as those generated by pulse width modulation (PWM) converters, and are expected to experience and withstand partial discharge activity during service. It specifies electrical qualification tests on representative specimens to verify fitness for operation with voltage-source converters. It also describes an additional classification system which defines the limits of reliable performance under converter-fed conditions.
