摘要
以塔山矿特厚煤层大采高综放工作面供电系统为例,主要从过电流、电压、漏电保护三方面进行了3.3 kV供电保护系统的研发;应用了EMTP的仿真系统,对各种故障时电压、电流波形和数据进行测试分析,仿真结果与研究结论一致。通过在塔山矿8105工作面1.5 a的工业性试验,供电保护系统的安全性和可靠性得到了有效验证。
A case study of tashan coal mine power supply system for fully mechanized caving mining face in thick coal seam, mainly research in 3.3KV power supply of over current , voltage and creepage. Adopted in building EMTP simulation platform and analyzing waveform and data of fault voltage and current, proving that result consistent with the theory. Through test in tashan coal mine workface of 8105 for 1.5 years,salty and credibility of power supply has been effectively verified.
