大型工业建筑的建筑面积和用电量都很大,超出单路市政 10 kV回路供电容量,此类项目考虑市政 35 kV进线供电或多路 10 kV回路供电.35 kV进线可采用二级降压或者一级降压给末端设备供电.从技术和经济两方面比较 35 kV进线二级降压、35 kV进线一级降压供电方案和多路 10 kV回路供电方案的优缺点,为大型工业建筑工程提出最优中压供电方案.
Comparison and Selection of the Medium-voltage Power Supply Scheme for a Large Industrial Building
Large industrial buildings usually have a large floor area and power consumption,which exceed the power supply capacity of a single municipal 10 kV circuit.For such projects,one municipal 35 kV incoming line or multiple 10 kV circuits may be used as power supply.The 35 kV incoming line can supply power to the end equipments through secondary step-down or primary step-down.The advantages and disadvantages of the secondary step-down scheme for 35 kV incoming line,the primary step-down scheme for 35 kV incoming line,and the scheme for multiple 10 kV circuits are compared from technical and economic perspectives,in order to provide the optimal medium-voltage power supply scheme for large industrial buildings.
