摘　　要：目前在掘进机过载保护的算法中常常采取定时限的过载保护算法。结合掘进机电机在使用过程的特点和现场使用情况,分析了几种典型的反时限过载保护特性,提出了一种基于PLC的电机过载反时限保护算法的参数。Currently in roadheader overload protection often taken the definite time overload protection algorithms. In this paper, in the course of roadheader characteristics, combined with on-site usage analysis of several typical characteristics of inverse time overload, we propose a suitable roadheader motor overload inverse time algorithm parameters.
