| Abstract: | To overcome the low efficiency of big cranes which adopt rotor clusters resistance for timing,new solution is proposed at the request of the 125t bridge type crane which controls the frequency-convertor,choosing the crane electrically control system disposition,drawing up the host promotion organization system diagram,and carrying on general frequency changer for trig unit choice with PLC coordination.The experiment result proves that:the engineering data surpasses over that of other variable velocity modulation plans,with each technical specification meeting the design request;and the energy-saving effect is obvious. |
