基于光纤电流差动保护的煤矿防越级跳闸研究
|
摘要
随着我国经济的不断发展,煤炭作为重要能源的需求量大幅度提升,保证井下开采安全具有十分重要的现实意义。供电网络正常运行是保证生产效率的基础与前提,需予以重视,从光纤电流差动角度出发,建立科学完善的防越级跳闸监控系统,尽量消除跳闸事故带来的不利影响,为井下作业安全保驾护航,进而提高煤矿企业的经济效益与社会效益,促进其向着更好的方向发展。
With the continuous development of China’s economy,the demand for coal has been greatly increased,so it is of great practical meaning to ensure the safety of underground mining. The normal operation of the power supply network is the basis and premise for ensuring production efficiency,which should be paid attention to. Based on fiber current differential,the anti-override trip monitoring system was established,to eliminate the adverse effects caused by tripping accidents,ensure the safety of underground operations,improve the economic and social benefits of coal mining enterprises,and promote the development of coal mining enterprises.
