【正文】 cuit breaker according to the choice of the general framework of values to select . For example: Route certain equipment capacity 530Kv, Kx take to calculate current of 704A, select the frame circuit breaker is 1000A, tuning is 800A。 3 substation located 2 units plus 2 units transformers, take the southern section of A, B two office supply. 10Kv power configuration of this project into two points, each at the two 10Kv lines, the power pany under the provisions of 10Kv power capacity: maximum load per channel is about to , two is the , design 1 , 3 bination of a substation 10Kv, power line, with a total capacity of 。 will be in the same city, different regions have different consumer groups . 3) the need to factor in the choice: parameters determined, the need for load calculation. Need to factor monly used method, the calculation will not repeat them. Need to explore is the need for coefficient selection, which in the current specifications, manuals and the unified technical measures is also not clear requirements, based on years of design experience that most end shops in the distribution or level within the household distribution box with case Kx generally take a while, in the calculation of the loop route to take to , the distribution transformers in the substation calculations take to . 3 substations set Load calculation based on the results of this project the total installed capacity of transformer , after repeated consultations with the power pany, respectively, in the project in northern, central and southern three sections set the three buildings into three power substations, 1 set 6 sets transformer substation, take the northern section of power supply。 followed to determine parameter index within the unit area of shops is also very important and plex because there is no clear indicator of the specification can refer to。 distribution。Power supply system of highrise building design Abstract: With the continuous development of city size, more and more highrise buildings, therefore, highrise building electrical design to the designers had to face. In this paper, an engineering example, describes the electrical design of highrise buildings and some of the more typical issues of universal significance, bined with the actual practice of an engineering solution to the problem described. Key words: highrise building。 electrical design。 load calculation 1 Project Overview The mercial 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. Project 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 the 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.
