标准摘要
[中文适用范围]： 本技术规范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，例如脉宽调制 (PWM) 转换器，并预计在使用期间能够承受局部放电活动。它规定了代表性样品的电气鉴定和验收测试，以验证是否适合与电压源转换器一起运行。本文件不适用于： - 仅由变流器供电用于启动的旋转机器。 - 牵引电气设备和系统。注：虽然本技术规范涉及电压源转换器，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，如果需要，可以使用类似的测试方法。 [外文原描述]： IEC/TS 60034-18-42:2008 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 pulse width modulation converters, and expected to withstand partial discharge activity during service. It specifies electrical qualification and acceptance tests on representative samples which verify fitness for operation with voltage-source converters.
