32、是用电负负荷有较较大增高高，在夏夏冬季节节或用电电高峰时时段时，用用电负荷荷有较大大的波动动，造成成供电的的不稳定定或是停停电时有有发生，为为居民用用电带来来了诸多多不便，因因此要求求小区供供电系统统要具备备更高的的可靠性性与安全全性。随随着城市市化进程程的逐年年加快，城城市用地地更加紧紧张、用用电负荷荷更加集集中，城城市的电电力电网网也逐步步由架空空向电缆缆过渡，老老旧的配配电方案案以及变变压器、配配电室等等电力设设备在安安全性、经经济性、环环保性等等方面都都难以满满足时下下的住宅宅用电负负荷要求求，由此此对于小小区的供供电方案案也有了了新的要要求。发展趋势势：将来来的供配配电系统统主要发发

33、展方向向为小型型化、节节能化及及更加自自动化。目目前对于于供电系系统的供供电可靠靠性尚感感不足，对对于某些些重要设设备如消消防设施施、生活活水泵、生生活电梯梯的供电电可靠性性还有待待提高。另另外，低低压配电电部分的的安全性性也需要要更多的的重视。小区供电电设计要要考虑下下列基本本要求： （1）安全全性 需要达达到相关关技术规规范与国国家标准准，且能能够保证证人身和和设备的的安全。（2）可可靠性 需要满满足小区区正常用用电的电电力负荷荷。（3）灵灵活性 需要适适用于多多种运行行方式，以以便于电电气设备备的维修修及切换换，并适适当考虑虑未来的的负荷发发展情况况。（4）经经济性 在符合合上述要要求的

34、前前提下，尽尽可能简简化设计计方案，降降低投资资及设备备运行、维维修的费费用，并并减少线线路有色色金属的的消耗和和电能的的节约。2 负负荷计算算2.1 供电负负荷的分分析近年来我我国的经经济建设设步入快快车道，居居民的生生活水品品不断提提高，越越来越多多的高能能耗电器器走进我我们的生生活，普普通家庭庭的用电电需求不不断上涨涨，例如如：空调调、电炊炊具、电电热水器器等，很很多家庭庭装有多多个空调调、彩电电、冰箱箱，而且且呈现出出强劲的的增长态态势，根根据以上上现状江江苏省住住宅设计计标准做做出如下下规定，一一般而言言高层的的计算负负荷可参参考每户户68kWW标准，小小高层及及多层可可参考每每户4

35、6kWW，除上上述方法法外还可可参考550的建建筑面积积标准，本本次设计计是针对对普通前前进小区区的设计计，根据据以上标标准，计计算负荷荷取值66kW每每户。本次设计计共有两两个院，每每栋高66层，则则每单元元为122户，一一号院为为114栋，每每两栋设设置一个个户外配配电箱，共共计7个配电电箱；二二号院为为1526栋，每每两栋设设置一个个户外配配电箱，共共计6个配电电箱。每每两个配配电箱设设置一个个配电屏屏，共计计7个配电电屏。由由配电屏屏引出线线路通向向配电箱箱，再由由配电箱箱引出线线路通向向楼栋单单元，之之后各单单元在引引出线路路到各户户。表2-11 负荷的的初步划划分变压器配电屏配电箱楼栋单元元1号变压器1号配电屏1#配电电箱1栋、22栋2#配电电箱3栋、44栋2号配电屏3配电箱箱5栋、66栋4#配电电箱7栋、88栋3号配电屏5#配电电箱9栋、110栋6#配电电箱11栋、12栋4号配电屏7#配电电箱13栋、144栋8#配电电箱15栋、166栋2号变压器5号配电屏9#配电电箱17栋、188栋10#配配电箱19栋、20栋6号配电屏11#配配电箱21栋、222栋12#配配电箱23栋、255栋7号配电屏13#配配电箱24栋、26栋-2.2 供电负负荷的计计算负荷计算算公式：有功计算算负荷 无功计算算负荷
