我矿主、到并提升机均采用TKD系列电控系统。由于TKD系列电控中可调闸速度闭环以及减速段限速环节以磁放大器、管形电阻、磁盘电位计等分立元件组成，磁放大器的固有特性是线性区差，反应慢，动态性能差，调整比较困难，现场使用效果差。因此，实际使用中，可调闭环节速度往往 My miners, to and hoists are using TKD series of electronic control system. Due to the TKD series of electronic control in the adjustable speed closed-loop and speed reduction section of the speed limit to magnetic amplifiers, tubular resistors, disk potentiometers and other discrete components, the inherent characteristics of magnetic amplifiers is the linear zone difference, slow response, poor dynamic performance, Adjustment is more difficult, poor field use. Therefore, the actual use of adjustable closed-loop speed is often
