井下永久避难硐室供电系统设计

Power Supply System Design for Underground Permanent Refuge Chamber

为保证井下工人的人身安全,井下需建设永久避难硐室。文章介绍了井下永久避难硐室的供电系统设计;避难硐室的电源设计;避难硐室供电系统的系统配置;接地与保护系统设计。实践证明:安全可靠的供电系统设计可以更好的保证灾变发生时避难硐室内避险人员的生存,保证通信、监控、照明等设施的正常运转,为井上救援人员提供信息。

As the production environment of underground coal mine is poor, with occasional happening of flood, gas explosion, dust explosion and other disasters, in order to ensure the safety of underground workers, permanent refuge chamber is required. The paper introduced the design of power supply system for permanent refuge chamber, including power source selection, system configuration, and the grounding and protection system design. Practice showed that, reliable power supply system can ensure the survival of personnel in refuge chamber, and guarantee the normal communication, monitoring, lighting and other facilities, offering information to rescuers.
