Abstract
The utility model belongs to control circuit technical field especially for monorail crane drive ware power -on control circuit, power -on control circuit is used for controlling monorail crane drive ware, power -on control circuit includes drive control system, signal sampling and drive single board, PU inverter part, power -on buffer loop and bus filter part, one end of PU inverter part is connected with positive terminal through power -on buffer loop, one end of PU inverter part is connected with negative terminal, buffer loop relay K2 is attracted after, makes monorail drive ware and gets electricity, until detecting that film capacitor C voltage Uc is greater than 70% of input voltage Ui, switches for main circuit relay K1 attraction, buffer loop relay K2 is disconnected, completes power -on buffer process, effectively avoids monorail crane drive ware in the operation process, causes the magnification of power -on buffer circuit failure because of main circuit relay K1 fault or misoperation and causes large current to pass through buffer loop relay K2 and buffer resistance R, and further prevents.
