摘要
阐述了三相四线制低压配电网中中性线断线的危害,提出一种基于直流信号注入的中性线断线检测方法,并通过采样电阻的电压判断断线点所在区间,进而最终得到断线点。通过仿真分析验证了方法的正确性。
Expounded the harm of the disconnection of neutral line, in a three-phase low voltage distribution network and presented a method for detecting the disconnection of line based on infusing of DC signal. The interval of the disconnected point was judged by th of the sampling resistor and finally the broken points could be located. The correctness of th was verified by simulation analysis.
