摘　　要：为在线监测变压器的运行状态,文中对以机械参数为主、电气参数为辅的变压器振动分析法进行了研究,在Windows CE平台上搭建了基于振动信号的电力变压器状态监测系统。选用EPC-8000嵌入式工控机主板作为操作系统平台,PCM-8208BS高速模拟量输入卡作为数据采集设备,VC++作为软件开发环境。系统装置能实时采集变压器的振动信号并进行分析,绘制出实时的时域波形图、频谱图和能量谱图,得出变压器的运行状态,并进行故障预警,具有良好的在线监测效果。In order to monitor the running state of transformer online, the method of transformer vibration analysis mainly depending on mechanical parameters and supplementary with electrical parameters is researched in this paper. And the on-line monitoring and fault diagnosis system for power transformer based vibration signal is built on Windows CE platform. The system device uses EPC-8000 as the operating system platform, PCM-8208BS high-speed analog input card as a data acquisition device, VC＋＋ as software development environment. The system device can acquire the vibration signal of the transformer in real time and do signal analysis. It can also draw a real-time time-domain waveform, fre- quency spectrum, the energy spectrum, obtain the status of operation of the transformer and do fault warning. It has a good line monitoring effect.
