摘要
电力是煤矿开采工作的主要能源支持,其供电系统直接关系着煤矿各项工作的正常运行。但是煤矿的开采工作大部分是井下作业,井下环境潮湿,地方狭窄,在设备运行时容易出现短路现象,使得煤矿供电系统可能出现越级跳闸事故,从而影响了煤矿井下作业的质量和效率。本文以现代通讯保护技术和光纤纵差保护技术为例,对煤矿供电系统的防越级跳闸技术的主要应用和影响进行了分析,希望能够帮助减少煤矿供电系统出现故障的次数,提高煤矿行业的经济利润。
With the continuous support of our national policies,China’s coal industry has become more and more stable,which not only meets the daily needs of our people,but also promotes the common development of other industries.Electricity is the main support for coal mining,and the power system is directly related to the normal operation of coal mines.However,most of the mining work in coal mines is underground,the underground environment is humid,and the place is narrow,which brings a lot of troubles to the normal operation of the power system.It is also prone to short-circuit phenomenon when the machine is running,which may cause a leap-level trip accident in the coal mine power supply system.This affects the quality and effi ciency of underground coal mine operations.Therefore,after reading a lot of data,this paper takes modern communication protection technology and fi ber differential protection technology as examples to analyze the main application and infl uence of the anti-override trip technology of coal mine power supply system.I hope this article can help reduce coal mine power.The number of system failures increases the economic profi t of the coal industry.
