Power supply system of high-rise building design
 
Abstract: With the continuous development of city size, more and more high-rise buildings, therefore, high-rise building electrical design to the designers had to face. In this paper, an engineering example, describes the electrical design of high-rise buildings and some of the more typical issues of universal significance, combined with the actual practice of an engineering solution to the problem described.
Key words: high-rise building; electrical design; distribution; load calculation
1 Project Overview
plex project, with a total construction area of 405570m2, on the ground floor area of 272330m2, underground construction area of 133240m2, the main height of 99m. ponents are: two office buildings, construction area is 70800m2, 28 layers, the standard story is .
2 Load Calculation
1) Load characteristics: electric load, much larger than the "national civil engineering technical measures" Large 120W/m2 indicators, especially in the electricity load more food, and different types of food and beverage catering different cultural backgrounds also high.
2) the uncertainty of a large load, because mercial real estate rents are often based on market demand, and constantly adjust the nature of the shops, making the load in the dynamic changes.
3) There is no specification and technical measures in t
