چکیده
Arc fault is one of the primary reasons that cause electrical fire. In power supply line, if arc fault occurs, the currents can not make protective equipments act, the arc fault can not be found easily, so electrical fire comes into being. Based on LabWindows/CVI, experimental studied the on-line arc fault detection system. AT89S51 Single Chip Microcomputer is used as lower computer, based on LabWindows/CVI, the upper computer program uses multithreading technology to detect and analyze the current signal. By arc fault detection algorithm, the system judges whether there has arc fault . The algorithm judges whether there has arc fault through detect if there has periodicity singularity points. The experiments show that this detection method of arc fault can detect arc fault in power supply circuits exactly and efficaciously.
