特大型矿井井下供电系统分析与设计

摘要

For reliability, flexibility and economy as a precondition, analyzes a super-huge coal mine electrical load conditions to determine the main wiring forms and equipment selection in the underground electrical system, and briefly analyzed the mine protection and grounding systems, formed a relatively perfect and reliability design in the underground power supply system.%以可靠性、灵活性和经济性为前提，分析了一座特大型矿井井下电气负荷的情况，确定了井下电气系统的主接线形式和设备选型，并对井下保护和接地系统进行了简要分析，形成了较为完善、可靠的井下供电系统的设计。
