Abstract
This paper described the Jinxing office building electrical systems design based on the design, design principles and methods and conclusions, which were: distribution system design, lighting design, mine grounding system design and engineering over the budget. Distribution system design include: distribution programme for the identification, electrical equipment selection, selection and arrangement of lines, load calculation; design of the lighting system include: source selection, choice of lamps, lighting and illumination choose calculation; Lightning Protection System design include: mine-building measures, in principle, the programme.
On the foundation of satisfies the electricity load which the extension part of the office building daily uses and the illumination condition, the synthesis construction and electricity design is based on some factors, such as energy conservation, environmental protection, artistic and so on. The pattern of power supplying system is TN-C-S and the power source which is buried straightly and is bring in by outdoor transformer substation. The choice of the primary illumination photo-source is the fluorescent lamp and the incandescent lamp. The quantity of the lamps is determined by the degree of illumination computation by the way of unit capacity and then carries on the reasonable arrangement to the lamps and lanterns. Computation is carried on the load by using needs the method of correlates to test the extension part of the office building. Lightning protection networks are used as the building’s anti-radar protection during the design of anti-radar. And then budgets of the entire projects are carried on at the end of the design.
