GB/T 20161-2008 in English

《GB/T 20161-2008变频器供电的笼型感应电动机应用导则》由TC26（全国旋转电机标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准仅涉及间接型变频器。此类变频器包括带中间回路的外施直流电流的变频器（电流型变频器）和外施直流电压的变频器（电压型变频器），或为方波型或为脉冲控制型，没有限制脉冲的数量、宽度或脉冲频率。
本标准适用于GB/T 21210-2007规定范围内的笼型感应电动机由变频器供电时在速度设定范围内的稳态运行，不包括起动或瞬态现象。

Scope

This standard only involves indirect frequency converters. Such frequency converters include frequency converters with external DC current (current type frequency converters) and external DC voltage frequency converters (voltage type frequency converters) with intermediate circuits, or square wave or pulse control types, without limiting pulses. Amount, width or pulse frequency. The frequency converter involved in this standard can be an analog control circuit or a digital control electrical appliance. The electronic shape device of the frequency converter can be of any type, such as transistor (bipolar or metal oxide effect transistor MOSfet), insulated gate bipolar Transistors (IGBTs), thyristors, turn-off thyristors (GTOs), etc. This standard applies to the steady-state operation of cage induction motors within the range specified in GB/T 21210-2007 when powered by a frequency converter within the speed setting range, excluding start-up or transient phenomena.
