标准范围

IEC 60034-18-42:2017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）转换器产生的脉冲电压，并且预计在使用期间经历和承受局部放电活动。它规定了对代表性样品进行电气鉴定测试，以验证是否适合使用电压源转换器。它还描述了一个附加的分类系统，该系统定义了转换器馈电条件下可靠性能的极限。

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.
