1、10kV小区供配电英文文献及中文翻译在广州甚至广东的住宅小区电气设计中,一般都会涉及到小区的高低压供配电系统的设计.如10kV高压配电系统图,低压配电系统图等等图纸一大堆.然而在真正施行经过中,供电部门(尤其是供电公司指定的所谓电力设计小公司)根本将这些图纸作为一回事,按其电脑里原有的电子档图纸将数据稍作改动以及断路器按其所好换个厂家名称便美其名曰设计(可笑不?),拿出来的图纸根本无法知足电气设计的设计意图,致使严重存在下面问题:(也不知道是职业道德问题还是根本一窍不通)1.跟原设计的电气系统货不对板,存在与低压开关柜后出线回路严重冲突,对实际施工造成严重阻碍,经常要求设计单位改动原有电气系统

2、图才能知足它的要求(垄断的没话讲).2.对消防负荷和非消防负荷的供电(主要在高层建筑里)应严格分回路(从母线段)都不清楚,将消防负荷和非消防负荷按一个回路出线(尤其是将电梯和消防电梯,地下室的动力合在一起等等,有的甚至将楼顶消防风机和梯间照明合在一个回路,以一个表计量).3.系统接地保护接地型式由原设计的TN-S系统竟误解成TN-S-C-S系统(室内的还需要做TN-C,好玩吧?),严格的根据所谓的三相四线制再做重复接地来施行,导致后续施工中存在重复浪费资源以及安全隐患等等问题.(违背建筑电气设计规范等等问题实在不好意思逐一例举,给那帮人留点混饭吃的面子算了)总之吧,在通过图纸审查后的电气设计图

3、纸在这帮人的眼里根本不知何物,经常是完工后的高低压供配电系统已是面目全非了,能有百分之五十的保留已经是谢天谢地了.所以.我觉得:住宅建筑电气设计,让供电部门走!大不了留点位置,让他供几个必需回路的电,爱怎么折腾让他自个怎么折腾去.Guangzhou,Guangdong,evenintheelectricaldesignofresidentialquarters,generallyinvolvinghigh-lowcellpowersupplysystemdesign.10kVpowerdistributionsystems,suchasmaps,drawings,etc.low-voltage
