摘　　要：提出了基于虚拟仪器结合PCI采集卡实现的接地故障检测系统的方案,充分利用了虚拟仪器的特点,实现了基于小波变换的先进检测方法,使直流系统的接地故障诊断的准确性有了很大的提高。A DC system grounding fauh detection device in terms of virtual instrument and PCI DAQ card is presented. This method makes full use of the virtual instrument. Furthermore, implementation of advance detecting method such as wavelet is made possible, and it effectively improves the accuracy of the error detection in a DC system.
