Abstract
The know-why the learns , real circumstances of this engineering of combination are used , the analysis conscientiously careful by way of to the primary sources , as well as short circuit calculation to decides on the scheme . The selection of the electric owner grasping the transformer substation wiring scheme , the mould selecting of major electric installation , the selection of main transformer platform number , capacity and model , as well as the various protections are surely calmly . Define finally this 60KV transformer substation electric owner's wiring diagram , and accomplishes the preliminary design to the 110KV transformer substation . Designing by way of this I have had a more overall understanding to the design of transformer substation , and makes me learn , not only the reliability will fully be thought over in the engineering designation and the flexibility , and still more will give consideration to many things economy , long-range nature and technical .
