摘要
通过采用一种新型检测线圈,开发了一种电弧故障电流检测系统。详细介绍了系统检测线圈和积分电路的设计,并进行了整体结构分析。试验结果表明:电弧故障电流检测系统有效地改进了电弧故障的检测质量,增大了电流检测的幅值范围和电流带宽范围,提高了检测的灵敏度,大大削弱了"积分漂移"现象。
An arc fault current detection system based on the a new current sensor was developed. The system detection coil and integral circuit were introduced. And the whole instructure was analysed. The results show that the arc fault current detection system effectively improved the quality detection of arc fault, increases the range of current detection, current bandwidth, improve the detection sensitivity and greatly weakened the drift phenomenon. The waveform detection is accurate and efficient in the process of test.
