摘　　要：设计了局部放电故障类型的诊断系统,实现局部放电脉冲的在线测量和引发放电的缺陷类型的识别。详细论述了局部放电故障诊断系统的软、硬件体系设计方案。放电脉冲波形测量、谱图统计分析和基于BP神经网络的智能识别验证结果表明,局部放电故障诊断系统实现了放电信号的在线测量、分析和诊断,系统的软、硬件方案也切实可行。The partial discharge fault diagnosis system was designed in this article for the reason that partial discharge could cause local damage to the dielectric and destroy the insulation equipment, finally result in safety hazard. The design of the hardware and software had been discussed in detail. The discharge pulse waveform measurements, the spectrum of statistical analysis and recognition result show that the system can complete the online measurement, analysis and diagnosis of partial discharge and the system scheme of hardware and software is feasible.
