| Abstract: | This paper introduces the first set of . thyristor DC reversible speed-adjustable system of a column crane for hoisting in our country. The system employs a staggered non-loopcircuit to avoid the occurrence of static loop current. So it can ommit four large current limiting reactors. On the other hand, the system uses an automatic controlling unit with threeclosed loops for the feedback of speed, current and voltage, so it can avoid the occurrence ofdynamic loop current. In addition, the system has a perfect protection and error signal unit. |
