基于超声波原理的变电站安全距离监测装置

摘要

为避免变电站运行人员、检修人员工作时无法与带电设备保持足够的安全距离而造成人员伤亡事故，设计了一种基于单片机的安全距离监测装置，笔者针对基于超声波原理的安全距离监测装置提出了在0.2~500 cm范围内实现准确测距的方法，该方法可对220 kV及35 kV系统的架空设备进行有效测距，测距的稳定性和准确性达到了100%，具有可靠性较高、实用性强、经济性强等优点。%In order to avoid the casualty accidents caused by unsafe distance between substation operator, maintenance per-sonnel and electrical equipment, a safe distance monitoring device based on the ultrasound principle is designed. The paper puts forward distance measuring method in the range 0.2 cm to 500 cm of the device, and the method can accurately mea-sure the distance of overhead equipment for 220 kV and 35 kV. It has the advantages of high reliability and strong practica-bility.
