为了解决煤矿综采工作面刮板输送机的重载启动、调速困难和运行效率低等问题,提出了一种新型智能高压变频器,即采用智能变频器控制电动机运转,取代传统的双速电机驱动方式,实现了刮板输送机的实时调速及节能运行。通过在陈四楼煤矿2801工作面的应用效果分析,该新型智能变频器减轻了刮板输送机启动载荷对机械结构和电网的冲击影响,解决了不同负载情况下的调速问题,降低了重载启动及运行时电动机损坏及链条断链事故的概率,具有高效、节能、稳定性高的特点。
In order to solve the problems of heavy load start-up, speed regulation and low operation efficiency of the scraper conveyor in the fully mechanized mining face of coal mine, a new type of intelligent high-voltage frequency converter is proposed, that is, the intelligent frequency converter is used to control the operation of the motor to replace the traditional two- Motor drive, to achieve a real-time scraper conveyor speed and energy-saving operation. Through the application effect analysis of the 2801 working face of Chen Silou Coal Mine, the new intelligent frequency converter can reduce the impact of the start-up load of the scraper conveyor on the mechanical structure and the power grid, solve the speed regulation problem under different load conditions and reduce the weight Containing the start and run-time motor damage and chain broken chain probability of accidents, with high efficiency, energy saving, high stability.
