施工现场临时供用电施工组织设计（Construction organization design of temporary power supply for construction site） 1. project overview (1) this project is * * province (city) * project, located in * City, {East}, {Economic Development Zone}, * South Road, * northbound, * Street East, west of * street. (2) the construction unit of this project is * * * company, the contractor is * company, the design unit is * city building design and Research Institute, the supervision unit is * company, the construction unit is * company. (3) the floor area of this project * m2, the structural situation is {wholly cast-in-place reinforced concrete frame shear wall}, the total height of buildings * m, common floor. The first floor of this project is designed *, and has a {fire control center}, {reporter} room, two to * layer design office space, * * design *. The ground floor is designed as {room}, and the underground two layer is designed as {garage}, and the mezzanine is designed as {garage}. 2. general situation of power supply and distribution for construction (1) site design (2) capacity of the platform is {500}kVA, and the ratio is 10 / 0.4kV, the transformer is located at the northeast side of the construction site, and the concrete location is shown in the general plan (not shown in this article). (2) the low voltage power supply system of this project adopts TN-S grounding system. The low voltage power supply mode is {}}, which is directly drawn from the field transformer substation or the box type substation (first level control), then sent to each distribution box (two and control), and one or two and the distribution system diagram. (3) a set of {5} fixed distribution boxes are set up on the spot. The specific configuration of the case is shown in Figure 2 (take the distribution box 5 as an example), and the location of the plane is shown in the general plan. (4) according to the fire protection requirements, a switch is connected in parallel with the low voltage switch at the box type s
