摘要
研究继电保护与故障检测方法在煤矿供电系统中的应用效果,为此后煤矿供电系统的合理应用提供依据。分析煤矿供电系统的继电保护类型,明确保护要求,根据实际故障确定检测方法,提出了过负荷保护、过电流与电流速断保护、单相接地保护等模式。结合实际案例,指出继电保护与故障检测模式在供电系统中的实际应用,保证检测模式的可行性。通过使用继电保护与故障检测方法,煤矿供电系统实现稳定运行,故障发生几率也明显降低,提高了采煤工作效率,保证了运行设备的灵敏性、速动性以及可靠性,为煤矿企业赢得更大的经济效益与社会效益。
The application effect of relay protection and fault detection method in coal mine power supply system was studied to provide basis for rational application of coal mine power supply system in the future.The relay protection types of coal mine power supply system were analyzed,the protection requirements were clarified,and the detection methods were determined according to the actual faults.Combined with practical cases,it points out the practical application of relay protection and fault detection mode in power supply system to ensure the feasibility of detection mode.Through the use of relay protection and fault detection methods,the coal mine power supply system to achieve stable operation,fault incidence is also significantly reduced,improve coal mining efficiency,ensure the sensitivity,quick and reliability of operating equipment,for coal mining enterprises to win greater economic and social benefits.
