交流提升机自动控制装置的研究

我国煤炭和冶金矿山大量使用的交流提升机，控制系统采用的可调闸控制，减速段限速保护和减速阶段电气制动三个磁放大器装置，存在快速性、稳定性，对环境参数的依据性，敏感性的较差等固有弊端，采用现代电子器件和先进的控制技术取代原控制系统中的1CF、2CF、3CF三个磁放大器及其落后的控制技术，并增加全新的电子速度给定环节，改善提升机性能。

The Research on Automatic Controlling Device of Alternating Elevator

Three magnetic amplifiers, such as adjustable-damper controlling, speed-limited protection in deceleration segment, and automatic braking largely used in alternated-elevator system in nation's coal and metallurgy exhibit quickness and firmness. The inherent negative features, such as: the dependence of environment - parameter, and the weakness of sensitivity are overcome by replacing 1CF. 2CF. 3CF magnetic amplifier as well as backward techniques of original controlling -system with modem electronic devices and advanced controlling techniques. This practice increases newly-given segment at electronic speed and improves the function of elevator.
