高压电缆绝缘在线监测及数据采集板的开发

High Voltage Power Cable On-line Insulation Detection and Development of Data Collection Board

为了及时发现运行中的电力电缆绝缘故障,依据准同步法测介损的基本原理,应用MAX125芯片,开发了电力电缆绝缘在线监测数据采集板,并阐述了硬件结构、软件功能和实现方式。实验证明,采集板同步采集良好,14位的采集数据精确。

Finding insulate faults of power cable in time, according to the base theory, of quasisynchronization measure dielectric loss, we develop the board of data collection of on-line insulation detection of power cable, the chip of MAX125 is applied in it. In the paper, the hardware architecture, software function and realize mode of the board of data collection are described. Conclusion is arrived at from test results that the board in-phase collects well and fourteen bits data are nice.
