摘要
针对隔爆兼本安型全数字变频绞车调速系统改造的实践,介绍应用AFE技术实现变频器四象限运行的原理和特点,分析"双线控制"提高控制系统的安全性和可靠性的技术措施,为井下绞车变频改造提供技术支持。
In accordance with the reform and practiee of the governing system of explosion-proof and nature- safe model all- digital frequency conversion winch, introduces the principle and character of the application of AFE technology in achieving frequency converter movement in four quadrants. The technological measures of ＂two - hne control＂ to improve the safety and reliability of the system is analyzed, it provides the support for the mine frequency conversion reform.
