摘要
阐述了淬火起重机对电控系统的要求,指出了老式电控系统的优缺点,论述了采用交流调压调速装置和直流调压调速装置组合式的电控系统,给出了起升机构电控系统原理图,对新老电控系统进行了比较。
The paper describes the requirement on the electric control system for quenching cranes,puts forward advantages and disadvantages of old-fashion electric control system,presents the new system combining the AC variable-voltage variable-speed device with DC variable-voltage variable-speed device,and provides the principle diagram of electric control system for lifting mechanism,with comparison of old and new electric control systems.
