摘要
分析煤矿主井提升机电控系统特点及发展趋势 ,选用电枢可逆全数字化控制晶闸管直流调速系统 ,实现行程监控和操作保护双 PL C控制和双安全回路 ,完成直流提升机的拖动。
The paper elaborates on the characteristics and developing trend of the electrical control system for the main hoisting shaft.Through the use of reversible brush and all-digital thyratron DC speed-regulating system for travel monitoring and control and operating protection,and the use of dual PLC control and double-loop system,an improved result can be achieved for the operation,protection and monitoring and control of the DC hoisting system.
