摘　　要：全面而准确地描述变流器电流过载能力指标的四要素是过载电流I1、基本负载电流I2、过载时间t1和负载周期T,它们是缺一不可的,且四要素已足够。等效电流系数KC可作为评判各种变流器在各种不同工况下电流过载能力强弱的一个"金标准"。对SINAMICS传动家族低压交流(200V≤额定输出线电压<1 000V)变流器的各种电流过载能力指标进行了系统地分析,并将其与6SE70系列工程型变流器的电流过载能力指标进行了对比研究。The four key elements which described comprehensively and exactly current overload capability index of converters are overload current I1 , basic load current I2, overload duration t1 and load cycle T and each is indispensable, and the four key elements has enough. The equivalent current coefficient Kc can various converters in a variety of different conditions as evaluation current overload capability strong or weak a ＂gold standard＂. It is analysed systematically that current overload capability index of low AC voltage（200 V≤rated output line supply〈1 000 V） converters of SINAMICS drive family and researched comparatively between current overload capability index of it and 6SE70 series engineering converters.
