冶金部安全技术研究所研制的双闭环可控硅动力制动装置鉴定会,由冶金部委托江西省冶金厅主持于1982年11月19～21日在江西浒坑钨矿召开。来自全国七个省市的41名矿山提升机方面的专家及有经验的工作者参加了这次鉴定会。双闭环可控硅动力制动装置为老矿山提升机提供了一套独立的制动系统,可有效地防止发生跑罐事故。该装置电源采用单相可控硅半控桥电路;用运算放大器作为综合调节元件,实现闭环运行;用速度闭环作为超
Ministry of Metallurgical Research Institute of Safety Technology developed double closed-loop silicon controlled power brake identification meeting commissioned by the Metallurgical Department of Jiangxi Provincial Metallurgical Office presided over the November 19, 1982 to 21 21 held in Jiangxi Hang pit tungsten. Experts and experienced workers from 41 mine hoists from seven provinces and cities nationwide participated in the appraisal. Double-closed-loop thyristor dynamic braking device for the old mine hoist provides a set of independent braking system, which can effectively prevent the accident occurred running tank. The device power supply using single-phase SCR semi-controlled bridge circuit; with operational amplifier as a comprehensive regulatory component, to achieve closed-loop operation; speed closed-loop as a super
