Abstract

With the development of economic construction, the construction and development

of present city of China are fast, its scale big , range is wide, is unprecedented.Technique
permeate the combination mutually with the information because of the building
technique with fast and fierce development of building electricity technology, in 1980’s
age the period the new building type-intelligent buildings turned out.

The focal point originally designed is the strong electricity, design the distribution

system of this project and motive force lighting system mainly.

For ground house not top-grade of 24 layers in project 3# floors in this , all house

above the ground. The floor space is about 800 square meters, it is that each layer is
high.3 m. The internal and external discrepancy in elevation of the room is 0. 45m.

This teacher apartment electricity the system design primarily include:

(1) low-voltage distribution system design, grade and is it require to supply power by

load, load calculate and distribution equipment choose and circuit lay .

(2) Motive force and lighting engineering design , by intensity of illumination level,

lighting quality , intensity of illumination calculate, power design and lighting
engineering design .

(3) defend thunder and earth design systematically

This engineering is three buildings, and carry to adop the double the power supply

the power supply, power supply to come from the transformer substation for second class
burthen power supply ,fire fight system and part of importance at the same time ,three
modulation four line system, adoption TN-C-S System ,adoption tree trunk type
