摘要
采用DASP2000智能信号采集和处理系统对LW 36-126型SF6高压断路器进行在线测试,利用小波变换方法对所测信号进行有效地除噪和重构,获得系统瞬态时频域动力学响应和特征量的特征指纹,揭示了分、合闸过程中系统的振动与冲击变化特性,为准确监测高压断路器的工作状态、设备维护和动力学设计提供了重要的参数。
An online testing for LW36-126-SF6 high voltage circuit breaker was done by DASP2000 intelligent equipment which can collect and transform signals automatically.Based on wavelet transform,necessary data during closing and opening process can be effectively got from the acceleration-signals including noise information,in order to gain transient dynamic response on time-frequency-domain and some important parameters.The revealed dynamic characteristics and parameters can be used to monitor and diagnose high voltage circuit,maintain equipment and dynamic design.
