智能马达保护器在矿山电机控制系统中的应用

Application of Intelligent Motor Control Unit in Mines

近年来,随着电子技术、计算机技术、总线技术的迅速发展,智能马达保护器以其优越的性能逐渐替代传统的热继电器成为电动机保护及综合控制的发展趋势。矿山电机系统中存在大量的大功率交流异步电机,其运行工况对电机控制及保护系统提出了较高的要求。在介绍了智能马达保护器原理功能和选型的基础上,深入探讨了智能马达保护器在矿山电机控制系统的综合应用及其不可取代的技术和经济优势。

In recent years,intelligent motor protection with its superior performance gradually become an alternative and integrated control trends to traditional thermal motor protection relays because of the rapid development of the electronic technology, computer technology and bus technology.The operating conditions of the motor control and protection system put forward higher requirements because there are a lot of high-power AC induction motor.This paper introduces irreplaceable comprehensive application of technical and economic advantages of the intelligent motor protection motor control system in the mine,based on the principle of intelligent motor protection functions and selection.
