基于PLC可控电源保护装置的优化设计

Optimization Design on PLC-based Controllable Power Protection Device

针对以电气设备为主的技能实训操作平台由于有时忘记关闭电源而引发的安全问题,设计一种集操作与保护为一体的电源保护装置。文章介绍该保护装置的结构设计,并从硬件及软件两个方面介绍了控制系统的设计。通过调试运行结果显示,该装置不仅能安全控制设备电源的通断,而且对长时间处于带电状态而无人操作的实训设备实现断电保护功能,在一定程度上消除了实训室的用电安全隐患,降低实训室的管理难度。

Aiming at the safety problems caused by forgetting to turn off the power of the technical training operation of electrical equipment,a power protection device which integrates operation and protection is designed.This paper introduces the structure 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.
