摘　　要：利用离散傅里叶变换(DFT)提取正常电流波形和电弧故障电流波形的各次谐波分量,并进行计算分析比对,快速判断输出电弧故障波形。电弧故障检测设备可大大缩短电弧故障保护电器产品的研发周期,为产品的生产提供一套可靠的质量验证。利用LabVIEW设计研发的电弧故障检测设备,与传统仪器相比,其在智能化程度、处理能力、数据采集分析、可操作性等方面具有明显的优势。The harmonic components of current waveforms under no-fault and arc fault condition are obtained by using the discrete Fourier transform(DF T).The arc fault current waveform can be quickly recognized by comparing and analyzing the current harmonic components.The research and development time of the arc fault detection device(AFDD)can be largely shorten by using this equipment.The equipment can provide a reliable quality verification for the AFDD products.The equipment is developed by using LabVIEW.Compared with the traditional instrum ent,the equipment has considerable advantage in the aspects of intelligent degree,processing capacity,data acquisition and analysis operability,etc.
