一、前言
Preface
随着频率控制传动技术的发展，对频率变速传动系统的要求越来越高，尤其是对采用快速切换的IGBT半导体现代变频技术，尽管脉冲频率高或更断时间仅毫微秒内，但它们会对周围环境产生电磁场。为保持变频率器正常工作不受电磁干扰，因此连接变频器与三相交流电机之间的电缆就要求具有抗干扰性能、较低的有效电容及较低的传输阻抗。
With the development of the converter drive technology, the requirement for the variable frequency drive are becoming more and more strict．Especially for the modern converter drive employing fast switching semiconductor IGBT，though it has high pulse frequency and refreshing time of only nanoseconds, it generates EMF that has adverse effect on the environment. In order to make the converter operate normally without the interference by EMF, the cable connecting the converter to a 3-phase motor must have high resistance to EMF interference, low effective capacitance and low transmission impedance.
二、应用范围
Scope of application
