The main content of this paper includes the development and application of box type substation,structure classification of box type substation extremely equipment selection and two system design.Design of high voltage side of rated voltage 35KV,LV rated voltage is 10KV,the main transformer capacity is 5000KVA.The main wiring uses the single bus. Keywords:box type substation;structure,a system,the two system 目 录 摘要 Ⅰ 目录 Ⅲ 第一章 引言 1 第二章 箱式变电站的类型、结构与技术特点 1 2.1 箱式变电站的类型 2 2.2 箱式变电站的技术特点 2 2.3 箱式变电站的箱体要求 3 第三章 35kV箱式变电站的总体结构设计 3 3.1 箱式变电站对主接线的基本要求 3 3.2 主接线的选择 4 3.3 高压接线方式 4 3.4 箱式变电站箱体的确定 4 3.5 变压器的散热处理 4 3.6 箱式变电站总体布置 5 第四章 35KV箱式变电站一次系统设计与设备选型 5 4.1 一次系统设计 5 4.2 箱式变电站设备选型应注意的方面 5 4.3 设备选型的基本原理 6 4.4 高压一次设备的选型 6 4.5 低压一次设备选型 6 4.6 高压熔断器的选择 6
