本文介绍了变电设备检修及预防性试验信息管理系统的开发。
This paper presents a development of informational management system for the overhaul and prevent test of substation device.
它用于对旋转电机的预防性维护和例行检修，其原理基于机器产生的机械振动频谱，故障机器会产生不同于“正常”机器的振动频谱。
The principle is based on the vibration spectrum generated by machines:a faulty machine would produce a different vibration spectrum from the normal one.
