煤矿井下供电系统串联故障电弧性能评估及诊断研究

Study on Performance Evaluation and Diagnosis of Series Fault Arc in Underground Power Supply System in Coal Mine

为保障煤矿井下供电系统安全,进一步提高用电稳定性,采用理论方法评估了供电系统串联电路故障电弧特征,运用实验和仿真模拟的方法分析了供电系统串联故障电路的电流、电压等参数变化。通过建立诊断串联电路电弧故障数据库,为串联电路电弧故障诊断提供了准确结果,保障了井下供电系统用电安全。

In order to ensure the safe of the underground power supply system and further improve the power stability, the arc characteristics of the series circuit fault in the power supply system were evaluated by theoretical methods, and the parameters such as current and voltage of the series circuit fault in the power supply system were analyzed by experimental and simulation methods. Through the establishment of the arc fault diagnosis database of series circuit, accurate results was provided for the arc fault diagnosis of series circuit, and the safety of the underground power consumption was ensured.
