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 TBM overload protection algorithms often take definite time overload protection algorithm. According to the characteristic of the boring machine motor and the field usage, several typical characteristics of the inverse time overload protection are analyzed, and a parameter of the motor overload inverse time protection algorithm based on PLC is proposed.
