摘要
结合安全评价过程中发现的小煤矿供电系统中存在的主要问题,从矿井电源点、矿井变电所运行方式、矿井一级负荷的供电方式、井下电气设备的保护等方面,探讨如何提高小煤矿供电系统的可靠性和稳定性,使小煤矿供电系统更好地保证矿井安全生产。
By considering the existing problems discovered in power supply system in small coal mines,and with regarding to aspects of power supply point,the running way of substation,the way of power supply of primary load,protection of electrical equipment of underground,probes into the way of improving the reliablity and stability of power supply system in small coal mines.Thus the power supply system in small coal mines can guarantee the safety production.
