煤矿主水泵高压软启动方案设计与应用

Design and Application of High Voltage Soft Starting Project of Main Water Pump in Coal Mine

近年来在解决大中型电机的启动问题上,软启动技术显示出强大的功能,尤其"一拖多"的软启动技术更受欢迎。通过分析软启动的技术特点,及"一拖二"软启动技术工作原理与特点,详细阐述了"一拖二"软启动技术的强大功能与优点,充分说明了煤矿水泵电控系统采用"一拖二"软启动技术的优越性与先进性。实践证明,此种软启动方案可以应用在大中型水泵电机的启动控制上,值得借鉴推广。

In recent years,the soft starting technique has showed a strong function in solving the starting problem of big medium-sized motors. Particularly, the soft starting technique with ＂a drag along much＂ is more popular. Through analyzing the technique characteristics of soft starting, and the working principle and characteristics of the soft starting technique with＂a drag along two＂, the strong function and advantage of the soft starting technique with＂a drag along two＂ are elaborated in detail. The superiority and advanced nature of the soft starting technique with ＂a drag along two＂ in the technical control system of the mine water pump are well explained. Practices have proved that the soft starting project can be applied in the starting control of big medium-sized water pump motors, it is worth drawing and promotion.
