摘　　要：高频局部放电在线监测技术是预防电缆绝缘故障最有效的方法之一,目前国内电缆存有量大,导致传统的巡检方式工作量巨大。设计了一种基于FPGA+ARM核心架构的电缆局部放电在线监测装置,采用与电缆本体非接触的安装方式,不会影响电缆的正常运行。该装置对电缆高频信号进行预处理后采集,有效降低了信号的噪声干扰。通过模块化设计,FPGA核心板负责数据的高速处理,ARM核心板负责系统的协调调度及数据收发,模块之间互不影响,具备良好的移植性,有助于后续的推广应用。Online monitoring of high frequency partial discharge is one of the most effective ways to prevent cable insulation failure.At present,there are a large number of domestic cables,and the workload of conventional inspection is huge.In this paper,an online cable partial discharge monitoring device based on FPGA+ARM core architecture is designed.The device adopts a non-contact installation mode with the cable body,which will not affect the normal operation of the cable.The device collects the cable high-frequency signal after preprocessing,which facilitates effective reduction in noise interference of the signal.Through the modularized design,in which FPGA core board is responsible for high-speed data processing and ARM core board is responsible for coordinated scheduling and data sending and receiving,the device is endowed with inter-module independence and good portability,which are conducive to subsequent promotion and application.
