故障电弧 meaning in Chinese

fault arc

The break - down arc and its protection in switchgear equipment
开关设备中的故障电弧及其防护
Fire accident can arise from low - voltage arc fault , and so it is necessary to detect arc fault
摘要低压故障电弧有引发火灾的危险，所以检测故障电弧是必要的。
Through studying the principle of dimmer and switch power supply , it was found that in some frequency points , by analyzing the phase of electric voltage and current it can tell if arc faults occur
研究调光灯及开关电源的工作原理可以发现，通过分析回路中电压电流在某些频率点的相位信息，可以有效判别是否发生了故障电弧。
As the electric power & electronic technology is used widely in low voltage area , the properties of voltage and current in normal working conditions of electrical appliance closely resemble or mimic the un - normal properties created by the arc fault , so it is difficult to distinguish between normal and un - normal cases
随着电力电子技术在低压领域的广泛应用，一些电器正常工作时的电压电流特性与故障电弧的典型特性相似，给检测工作带来了难度。
