摘要
统计变压器中40%故障由其电压转换开关引起,该文通过对变压器中电压转换开关进行的切换测试,分析了由声学传感器采集的切换信号,进行了模式识别,从而可以确认不同变压器在不同电压切换等级的典型信号值。这样就为识别变压器故障提供了系统的科学比对依据,并且通过实验证明了该方法的有效性。
In this paper though the test on the switch of the voltage transformers,collect the signals with the acoustic sensors and analyze them,with pattern recognition to recognize the typical signal value between different transformers and voltage switches,in order to provide the data basis for the failure recognition and analysis.
