摘要: 介绍了刨煤机成套开采系统的组成及变频调速技术在该系统中的应用。变频调整技术的应用提高了传动系统的调速效率，使得传动系统能够实现无级调速，降低了刨煤机成套开采系统在启动时传动系统承受的振动载荷，解决了刨头牵引电动机因频繁启动、换向而发热的缺陷，实现了真正意义上的“软启动”，提高了刨煤机成套开采系统的传动可靠性和工作安全性。Abstract: The paper introduced composition of plough mining system and application of technology of frequency-conversion speed-regulation in plough mining system. The application of technology of frequency-conversion speed-regulation improves efficiency of speed-regulation of driving system, realizes infinite speed-regulation of driving system, reduces vibrational loads of driving system of plough mining system in starting, solves exothermic problem causd by frequent start and commutating of driving motor of plough, and realizes really soft start. The technology improves driving reliability and working safety of plough mining system.
