【正文】 10 結(jié)束語 隨著商業(yè)設(shè)計(jì)項(xiàng)目越來越復(fù)雜，需要設(shè)計(jì)人員不斷地提高設(shè)計(jì)水平，精心設(shè)計(jì)，作出精品。根據(jù)以上要求及地上、地下建筑防火分區(qū)和業(yè)態(tài)形式的不同情況，采用了兩種略有差別的方式。按照國際電工委員會(huì)（ IEC）及中國國標(biāo)的要求： ① 所有的配電編號(hào)要簡(jiǎn)單明了，不能太箱和線路編號(hào)不重復(fù)。 8 戶配電箱的設(shè)計(jì) 在商業(yè)地產(chǎn)設(shè)計(jì)中，往往只為商鋪設(shè)計(jì)一個(gè)電表箱，而出線回路由用戶根據(jù)自己的需要進(jìn)行二次設(shè)計(jì)，但是商鋪內(nèi)風(fēng)機(jī)盤管的供電很難解決，無法進(jìn)行空調(diào)系統(tǒng)的整體 調(diào)試。 ② 為方便裝修設(shè)計(jì)，在每個(gè)防火分區(qū)內(nèi)設(shè)置了公共區(qū)域照明配電箱和應(yīng)急照明配電箱，以便明確裝修設(shè)計(jì)的電氣配電分界點(diǎn)。需要指出的是由于各層的業(yè)態(tài)比較復(fù)雜各層的防火分區(qū)上、下層不對(duì)應(yīng)，使得有的豎井在負(fù)責(zé)本防火分區(qū)供電的同時(shí)，還要負(fù)責(zé)相鄰的防火分區(qū)的供電。例如：某豎井一段母線負(fù)責(zé) 1～ 3 層供電，當(dāng) 1 層由于變化容量增大，而 3 層容量減小時(shí)，就可使用 1 層的備用插接箱把 3 層富裕的容量配給 1 層使用。對(duì)供電回路的條文解釋系指 “從低壓總配電室（包括分配電室）至最末一級(jí)配電箱，與一般配電線路 均應(yīng)嚴(yán)格分開 ”。本工程配置兩處 10Kv 電源引入點(diǎn)，每處為兩路 10Kv線路 ,根據(jù)供電公司對(duì) 10Kv電源容量的規(guī)定：每路最大負(fù)荷為 左右，兩路即為 ，設(shè)計(jì) 3變電所合用一處 10Kv,電源進(jìn)線，總?cè)萘繛?； 2變電所內(nèi)變壓器和 10Kv,冷水機(jī)組共用一處 10Kv 電源進(jìn)線，總?cè)萘繛?。 3）需要系數(shù)的選擇：參數(shù)確定后，需要進(jìn)行負(fù)荷計(jì)算。 2 負(fù)荷計(jì)算 1）負(fù)荷特點(diǎn) :用電負(fù)荷大 ,遠(yuǎn)大于《全國民用建筑工程設(shè)計(jì)術(shù)措施》中大120W/m2 的指標(biāo) ,尤其是餐飲的用電負(fù)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。 A1 on behalf of A, No. 1 shaft fed a distribution box. Fed a lowvoltage circuits, such as the number of uses: W36AL1A1, W36) indicates that the route back to power supply transformer 3, 6, feed the power distribution cabi, AL1A1, said the then the first loop of the distribution box for the AL1A1 and so on, and so on. 10 Conclusion With more and more plex mercial design projects, designers need to continually improve the design level, designed to make fine. These are only bits of the design in the business lessons learned, and the majority of designers want to municate 高層建筑供配電系統(tǒng)設(shè)計(jì) 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(jì)就成為設(shè)計(jì)者不得不面對(duì)的問題。 shortings is a higher cost. BA system control advantages of using low cost, simple control。 2 substation transformers and 10Kv, 10Kv chillers sharing a power line, with a total capacity of . The design of the substation layout, in addition to meeting regulatory requirements, it also need to consider the highpressure cabis, transformers and low voltage power supply cabi by order of arrangement, especially in low voltage distribution cabi to feed the cable smooth and easy inspection duty problems are not seriously consider the construction of the cable crossing will cause more long detour, a waste of floor space, and convenient inspections and other issues. 4 small fire load power supply In the design of large mercial projects often encounter small fire load of electrical equipment and more dispersed distribution, if fed by a substation, a substation will be fed a lot of lowvoltage lowcurrent counter circuit breaking capacity circuit breaker and conductor of the dynamic and thermal stability in a certain extent. According to GB500451995 fire protection design of tall buildings, rule should be used in Fire Equipment dedicated power supply circuit, the power distribution equipment shall be provided with clear signs. Interpretation of the provisions of the power supply circuit means from the lowvoltage main distribution room (including the distribution of electrical room) to last a distribution box, and the general distribution lines should be strictly separated. In this design, the use of methods to increase the level of distribution, that is different from the substation bus segments, respectively, a fire fed a special circuit, set in place two distribution cabis, distri
