摘要
华丰煤矿采用隔爆型高—低—高调速方案实现井下6kV高压防爆变频调速功能,采用全数字无速度传感矢量控制技术确保提升机提升力矩,采用PWM斩波调制控制技术减少谐波污染,控制系统可靠,调速性能平稳,具有很好的推广应用价值。
Huafeng Coal Mine adopts the scheme of high - low - high to achieve function of high - pressure flame - proof and frequency. The moment of hoist is ensured by total numerical no - speed sensor vector control technology. PWM chopped wave modulation techniques is used to decrease wave pollution. The control system is reliable and worth application and dissemination.
