预制装配式220 kV终端变电站典型设计研究

Study on Typical Design of Fabricated 220 kV Terminal Substation

摘要: 随着电网建设进度的加快，如何缩短变电站的建设周期显得日益重要。预制装配式变电站通过工厂预制和现场安装两个阶段建设，越来越成为城市变电站推崇的建设方式。另外，以往必须先确定设备再进行设计，从而再进行施工安装的流程成为了必须打破的瓶颈。本设计方案主要研究预制装配式变电站内的主要设备的通用基础，可在设备订货前就按通用基础、通用接口予以设计，实现土建先行，从而达到加快工程建设速度的目的。

Abstract: With the accelerated construction schedule of power grid, how to cut construction period of substation is an increasingly important issue. Through the two stages of construction of factory prefabrication and site installation, fabricated substation is becoming more and more respected city substation construction side. Moreover, we must design after determining devices firstly, and then is civil work and equipment installation. Now we must break the bottleneck of this traditional mode. The main research of this design scheme is the general base of electrical equipments in fabricated substation. In accordance with the general base and general interface, we can design before equipment ordering and realize civil work first, so as to achieve the purpose of speeding up the pace of substation construction.
