摘要
探讨规范对一级负荷供电要求的规定;分析双电源回路末端切换供电方式与双电源首端切换单回路供电方式,比较其供电可靠性及建设投资,提出合理选择一级负荷供电方式的策略。
The article discusses the requirements on the power supply of first grade loads in the standards and based on the analysis of terminal switching mode of double supply loop and head end switching mode of double supply single loop,compares the power supply reliability and construction investment and introduces a solution to the selection of reasonable power supply mode of first grade loads.
