摘要:隨著城市規(guī)模的不斷發(fā)展,高層建筑越來越多,因此,高層建筑電氣設(shè)計就成為設(shè)計者不得不面對的問題。本文結(jié)合工程實例,介紹了高層建筑電氣設(shè)計中一些比較典型且具有普遍意義的問題,結(jié)合某工程的實際做法闡述了問題的解決方法。
關(guān)鍵詞:高層建筑;電氣設(shè)計;配電;負荷計算
1工程概況
本項目商業(yè)綜合大樓,總建筑面積為405570m2,地上建筑面積272330m2,地下建筑面積133240m2,主體高度99m。項目組成為:辦公樓兩座,建筑面積為70800m2,28層,標準層高為3.2m。
2 負荷計算
1)負荷特點:用電負荷大,遠大于《全國民用建筑工程設(shè)計術(shù)措施》中大120W/m2的指標,尤其是餐飲的用電負荷更大,而且不同類型、不同飲食文化背景的餐飲差別也很大。
2)負荷的不確定性大,因為商業(yè)地產(chǎn)往往根據(jù)市場租的需求,不斷調(diào)整商鋪的性質(zhì),使得負荷在動態(tài)變化之中。
3)目前的規(guī)范和技術(shù)措施沒有對商業(yè)項目中不同類別商鋪的參數(shù)指進行細化,工程設(shè)計中的負荷計算缺少據(jù),大多數(shù)情況只能靠設(shè)計人員憑借以往工程經(jīng)驗進行計算。
負荷參數(shù)的選擇:針對以上遇到的問題,進行負荷計算時,首先與開發(fā)商銷售部門進行良好的溝通,確定各層的業(yè)態(tài)形式商鋪面積和性質(zhì),這是電氣負荷計算的基礎(chǔ)依據(jù);其次確定商鋪內(nèi)單位面積參數(shù)指標也很重要且復(fù)雜,因為規(guī)范中沒有明確的指標可以參考;而且不同城市間的經(jīng)濟發(fā)展水平不均衡,用電指標也不同;便在同一城市不同區(qū)域的消費群體也有差異。
3)需要系數(shù)的選擇:參數(shù)確定后,需要進行負荷計算。一般采用需要系數(shù)法,計算過程不再贅述。需要探討的是需要系數(shù)的選擇,這在現(xiàn)行規(guī)范、手冊及《統(tǒng)一技術(shù)措施》中也沒有明確的要求,根據(jù)多年的設(shè)計體會認為,在配電最末端商鋪內(nèi)戶箱或?qū)优潆娤溆嬎銜rKx一般取1,在各回路干線計算時取0.7~0.8,在變電所各配電變壓器計算時取0.4~0.6。
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
The commercial complex 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 components are: two office buildings, construction area is 70800m2, 28 layers, the standard story is 3.2m.
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 commercial real estate rents are often based on market demand, and constantly adjust the nature of the shops, making the load in the dynamic changes.
