变频器应用于煤矿井下带式输送机的技术研究

Research on the Application of Frequency Converter in Belt Conveyor in Coal Mine

通过分析长距离、大运量和高转速带式输送机的使用要求,提出将交流变频调速装置应用于煤矿井下带式输送机,实现启停平稳、运行高效、驱动平衡和工作安全可靠,并在此基础上进行变频调速技术散热、调速和功率平衡问题研究,为长距离、大运量和高转速带式输送机的发展奠定了良好的基础。

By analyzing the use requirements of long distance, large volume and high speed belt conveyor, proposed to use AC variable frequency speed control device in coal mine belt conveyor to achieve smooth start and stop, run efficient, drive balance, work safe and reliable.Then studied the cooling, speed regulation and power balance problems of frequency converter. The results of this study laid a good foundation for the development of long distance, large volume and high speed belt conveyors.
