我矿用硅整流器取代主井的提升控制系统交直流供电机组后,降低了电耗,提高了效率,消除了噪音,改善了对设备和信号监听条件,保障了设备能力的正常发挥;但电压质量常因外部电网电压波动而变化,影响了整个系统的延时、起动、调速及保护回路的性能。为此,我们设计并安装了一台可控
I mine silicon rectifier to replace the main shaft of the lifting control system AC and DC power supply unit, reducing power consumption, improve efficiency, eliminating noise, improve the equipment and signal monitoring conditions, to protect the equipment capacity of the normal play; but the voltage Quality often changes due to external grid voltage fluctuations, affecting the entire system delay, start, speed and protection circuit performance. To this end, we designed and installed a controllable
