| 摘 要： | 高电压电缆局部放电严重影响电缆的寿命和供电可靠性。电缆局部放电信号微弱,特征信号频率高达300MHz,具有电容式和电感式两种传感器,采样点多,数据采集难度大。采用美国国家仪器有限公司生产的多路选择板卡PXI2593、PXI5154高速数据采集板卡及其相关的计算机系统,作为高压电缆在线监测系统的数据采集硬件平台,设计数据采集通信子系统和客户端子系统,实现采样通道选择、数据采集和存储、采样数据显示、历史数据回放、信息参数配置与用户信息管理。

| Abstract: | Partial discharge of power cable is a serious factor to shorten the life of cable and power supply reliability.It is difficult to sample the partial discharge signal because of its weak magnitude and high 300MHz spectrum.Data acquisition PXI5154,Multi-channel switch PXI2593 and the computer system produced by National Instrument Co.,LTD were used to be the platform for data sampling.Data sampling & communication subsystem and client subsystem were designed to realize channel selection,data sampling and stor... |
