摘要
电弧现象是引起电气火灾的重要因素之一,及时有效地检测故障电弧是避免电气火灾的一个重要途径。介绍电弧的产生原因及对故障电弧检测的现有技术,举例说明一种故障电弧探测器的设计方法。
The phenomenon of arc is an important cause of electric fire; therefore, an important way to avoid electric fire is to effectively detect the arc fault in a timely manner. In this paper, the causes of electric arc and current detection technologies for the are fault are introduced; an example is taken to describe the design method of a fault arc detector.
