文档介绍：35kV箱式变电站设计
摘要:箱式变电站又称户外成套变电站,也有称做组合式变电站,它是发展于20世纪60年代至70年代欧美等西方发达国家推出的一种户外成套变电所的新型变电设备,由于它具有组合灵活,便于运输、迁移、安装方便,施工周期短、运行费用低、无污染、免维护等优点,受到世界各国电力工作者的重视。进入20世纪90年代中期,国内开始出现简易箱式变电站,并得到了迅速发展。
本课题的主要内容包括箱式变电站的发展应用,箱式变电站的结构分类,以及箱式变电站一次系统设计极其设备选型,二次系统设计,以及箱式变电站的智能监控系统。35kV箱式变电站的设计高压侧额定电压为35kV,低压侧额定电压为10kV,主变压器容量为5000kVA。主接线采用单母线分段接线。

Design of 35 kV box-type transformer substations
ABSTRACT: Box-type transformer substation calls again outdoor a transformer substation, also call to do the sectional transformer substation. It is a development to wait to 70's Europe and America western prosper in the 60's of 20 centuries the nation release a kind of outdoor the set changes to give or get an electric shock of new change to give or get an electric shock the equipments, because it have bination vivid, easy to conveyance, move, install convenience, start construction the period is short and circulate the expenses low, free from pollution, do not need maintenance etc. advantage, suffer the munity electric power the worker values. Enter the middle of 90's of 20 centuries. The domestic starts appearing the simple box-type transformer substation, and got the quick development.
The article regard box-type transformer substation as a development for relating box-type transformer substation applied, the construction of box-type transformer substation divides into se-section, emphasizing the treatise box-type transformer substation a the very equipments in design in subsystem chooses the type, two subsystems design, and the intelligence of box-type transformer substation supervises and control the system. The design high pressure side sum of box-type transformer substation settles electric voltage as 35 kvass, the low-pressure side sum settles electric voltage as 10 kvass, main transformer capacity is 5000 kvetched lord connects the single mother in adoption in line cent segment connects the line.
