电弧故障探测器与保护器的差异分析

Difference Analysis of Arc Fault Detector and Protector

简要介绍了电弧发生装置,从判定准则、电弧故障检测试验、误响应试验、屏蔽试验、应用领域几个方面,分析了电弧故障探测器与电弧故障保护电器之间的差异。指出电弧故障探测器仅具有故障电弧报警的功能,而电弧故障保护器是在电弧故障探测器的基础上增加了断开机构,具有断开故障电弧电路保护的功能。

This paper introduced the arc generator, and analyzed the performance differences of arc fault detectors （AFD） and arc fault detection device （AFDD） in aspects of criterion and test items （ are fault detection test, error response test, shielding test,and application）. It is pointed out that the AFD only has the function of arc fault warning while the AFDD has the protection function of breaking arc fault circuit. So the AFDD product increases the breaking mechanism based on AFD.
