摘要
从数据采集与传输可靠性、抗扰能力、电磁兼容性、界面友好性角度出发,搭建了高压断路器声-振-行多信号联合监测实验平台,该平台包含声音、振动、行程传感器设计及选型、采集系统控制箱设计、上位机设计三部分.然后以SF6 高压断路器的分闸弹簧故障为例,对故障进行模拟设置,通过搭建的实验平台,对故障信号的采集、传输、存储、呈现及波形对比分析,实现了高压断路器声-振-行多信号联合监测实验平台的应用,为后续高压断路器机械故障特征提取及故障诊断提供可靠的数据基础.
Abstract
From the perspectives of data collection and transmission reliability,anti-interference ability,electromagnetic compatibility,and user-friendly interface,a high-voltage circuit breaker(HVCB)multi signal(including sound,vibration,and travel signals)joint monitoring experimental platform has been built.The platform includes three parts:sound,vibration,travel sensor design and selection,acquisition system control box design,and upper computer design.Then,taking the opening spring fault of SF6 HVCB as an example,the fault was simulated and set up.Through the experimental platform built,the collection,transmission,storage,presentation,and waveform comparison analysis of fault signals were achieved.The application of the HVCB multi signal joint monitoring experimental platform was achieved,providing a reliable data foundation for subsequent mechanical fault feature extraction and fault diagnosis of HVCBs.
