Renovation and Optimization of Operation Mode of Dual-circuit Power Supply System in Coal Mine
-
摘要: 针对目前井下双回路供电系统大多不能符合《煤矿安全规程》2009版规定的问题，对井下双回路供电系统的运行方式提出了革新和优化办法；指出采区变（配）电所双回路供电系统采用并列运行方式还存在着由于电气重新整定而造成的转换不便问题，需对该问题作进一步的研究。Abstract: For the problem that most dual-circuit power supply systems in coal mine underground could not accord with requirements of version 2009 of Coal Mine Safety Regulations, the paper presented a way of renovation and optimization of operation mode of dual-circuit power supply system, and pointed out that dual-circuit power supply system which uses parallel operation mode still has a problem of uneasy switchover caused by electric resetting and the problem should be further researched.
