Analysis and Solution of Motor Cable Defects on the Output Side of Invertor
In a copper rod plant,in its continuous casting and rolling production line the pinch rolling motor and the laying head motor had broken down,and motors troubleshoot is as a engineering examples.according to the electromagnetic wave transmission line theory,by analysis of the causes about cable capacitances increase,we can learn the cable capacitances how to influence the motors,how to form the motor end peak voltage and current peak,therefore motor winding insulator was breakdown,and put forward the solution.
