Optimization Design on PLC-based Controllable Power Protection Device
Aiming at the safety problems caused by forgetting to turn off the power of the technical training operation of electri-cal equipment,a power protection device which integrates operation and protection is designed.This paper introduces the struc-ture design of the protection device,and designs the control system from both hardware and software aspects.The debugging and running results show that the device can not only safely control the power supply of the equipment,but also realize the power failure protection function for the training equipment that is in the live state for a long time but not operated by anyone.To a certain extent,it eliminates the hidden danger of power consumption and reduces the management difficulty in the training room.
