改进型35kV简易变电站设计研究

Study on the Modified 35kV Simple Substation Design

针对常规35kV变电站投资大,建设周期长及现有35kV简易变电站一次设备繁多,二次设备配置复杂等特点,提出了改进型简易变电站设计方案。该方案能够满足负荷增长需求,具有建设周期短、施工方便、投资回收快、一次设备安装方便、二次无工作量、便于拆除、不对远期网架规划产生影响等突出优点。

The conventional 35kV substation consumes large investment and long construction period, and the primary design of present 35kV simple substation needs various equipments, while the equipment allocation of secondary design is too complex. On account of the above problems, this paper is aiming at the design scheme of modified simple substation. This scheme can meet the need of load development, and has various characteristics, such as short construction period, convenient construction, fast return on investment, easy installation of primary design, no workload of secondary design, easy to dismantle, no impact on grid planning in the future, etc.
