摘　　要：介绍了低压成套开关设备内部故障电弧,结合标准GB/Z 18859—2002及IEC/TR 61641,对低压成套开关设备进行内部故障引弧试验并对试验现象进行分析,阐述了引起内部故障电弧的原因,通过对样机进行合理优化改造设计,并采取了必要的故障电弧防护措施,使得顺利通过试验,为通过引弧试验提供了参考。Introduction was made to the internal fault arc of low-voltage switchgear assemblies. Combining with the standard of GB/Z18859--2002 and IEC/TR61641, this paper carried out the internal fault arc ignition test of low-voltage switchgear assemblies and analyzed its test phenomenon. This paper expounded the cause of internal fault arc. The prototype was optimized and designed. The system carried out the necessary fault arc preventive measures to sweep through the test, which provides references for the arc ignition test.
