摘要
结合工程实际,介绍了环网供电系统的概念、原理,分析了环网供电单元,阐述了熔断器与变压器配合保护计算,讨论了环网供电系统的开环与闭环点选择及闭环操作。环网供电系统的正确应用,保证了供电的可靠性和经济性,可为类似工程提供参考。
Combined with the actual engineering, the concept and principle of ring network power supply system were introduced. The ring main unit was analyzed. The calculation on fuse protecting for transformer was described. The selection about open-ring point and closed-loop point of ring network power supply system and the operation for closed-loop were discussed. The exact application on ring network power supply system ensured the reliability and economics of power supply. It provided references for the similar engineering.
