TMdrive-10e2系列逆变器电流过载能力指标剖析

Analysis and Research on Current Overload Capability Index of TMdrive-10e2 Series Inverters

利用笔者所首创的描述电流过载能力指标4要素原则和等效电流系数KC法系统地分析和研究了TMEIC公司TMdrive-10e2系列逆变器在各种不同工况下的电流过载能力指标,发现该系列逆变器的平均相对电流过载能力指标小于交流传动系统中的Siemens公司6SE70系列工程型变流器的相应值,给出了市场上几种重要交直流变流器的平均电流过载能力指标的序次。根据笔者所首创的基于变流器电流过载能力指标的缺陷理论,可判定TMdrive-10e2系列逆变器不存在第1~第3类缺陷。

The author invents the four key elements and equivalent current coefficient KC of evaluating the currentoverload capability indexes of converters. By applying them in analyzing the current overload capability indexes ofTMEIC TMdrive-10e2 series inverters under different working conditions,a conclusion is drawn that it is lower thanthe Siemens 6SE70 series converters. In addition,the ranking of the average current overload capability indexes for themost universally used converters is listed in the paper. Furthermore,according to the author′s pioneering defect theoryevaluating the current overload capability indexes of converters,it is certain that there is no 1st^3rd kinds defects inthe TMdrive-10e2 series inverters.
