摘要
介绍了有载调压开关状态检测背景,其后简述了振动法和电流法结合分析有载调压开关的优势及振动法和电流法原理及检测设备设计,通过现场测试分析有载调压开关机械振动信号和电流信号,有效证明振动法与电流法结合分析是一种有效的有载调压开关状态判断方法。
Firstly, this paper introduces OLTC state detection background.Subsequently the advantage of vibration method com-bined with current test method for analyzing OLTC state is briefly illustrated.Then the principle of vibration method, current testing method, and the equipment design are introduced.Finally, through field testing and analysis of OLTC mechanical vibration and cur-rent signals, it shows that the vibration analysis method combined with the current test method is effective for OLTC state judging.
