“软启动”在带式输送机电控系统中的应用

长期以来,我国煤矿井下的辅助运输带式输送机的电机调速及启动方法比较落后,不仅浪费电能,而且大大缩短了机械设备的使用寿命,同时给电网造成冲击。文章主要介绍了"软启动"在带式输送机电控系统中的应用以及电机的启动方式,"软启动"的原理、特点和使用效果。

Application of "Soft Start-up"in Belt Conveyor Electronic Control System

For a long time,China's coal mine used to assist in the conveyor's start motor and the methods behind not only a waste of energy,but also greatly shortened the useful life of machinery and equipment,at the same time a blow to the power grid.This paper introduced the "soft start" in the electronically controlled conveyor system,as well as electric start,"soft start" principle,the use of the characteristics and effects.
