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,它是一种高压开关设备、配电变压器和低压配电装置,按一定接线方案排成一体的工厂预制户内、户外紧凑式配电设备,即将高压受电、变压器降压、低压配电等功能有机地组合在一起,安装在一个防潮、防锈、防尘、防鼠、防火、防盗、隔热、全封闭、可移动的钢结构箱体内,机电一体化,全封闭运行,特别适用于城网建设与改造,是继土建变电站之后崛起的一种崭新的变电站。
10kV箱式变电站的设计高压侧额定电压为10kV,,主变压器容量为1 600kVA。主接线采用单母线分段接线。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及其设备选型,二次系统设计,以及箱式变电站的智能监控系统。
关键词:箱式变电站结构一次系统二次系统
Abstract
Box-type transformer substation, calls again outdoor a transformer substation, also call to do the sectional transformer substation, it is a high-voltage switchgear, distribution transformers and low voltage distribution equipment, wiring scheme according to certain pre-arranged one indoor plants, pact with electrical equipment, high pressure will be electric, step-down transformers, low voltage power distribution and other functions anically, installed in a moisture-proof, rust, dust, vermin, fire, theft, insulated, fully enclosed, mobile steel s, mechanical and electrical integration, fully enclosed run, especially for work construction and transformation, following the construction of a substation after the rise of the new substation.
The design high pressure side sum of box-type transformer substation settles electric voltage as 10 kV, the low-pressure side sum settles electric voltage as , main transformer capacity is 1 600 kVA. Sub main wiring connection using a single bus. The main topics include the development and application of box-type substation, box-type substation structure classification, as well as a box-type substation system design and equipment selection, the second system design, and box-type substation intelligent monitoring system.
Key Word: box-type transformer subst
