下载后可任意编辑110kV 变电站一次系统设计12024 年 4 月 19 日下载后可任意编辑110kV 变电站一次系统设计 摘 要 本设计首先对课题所给原始数据进行分析，然后进行变电站的负荷计算和无功补偿计算。确定无功补偿装置及无功补偿容量。其次就是根据原始数据，进行短路计算和主接线的选择，然后根据短路计算的结果，对各种一次设备进行选型校验；完成主接线选择及设备选型后，根据设计要求绘制该变电站一次系统图。最后进行防雷、接地、变电站布置以及变电站自用电系统的设计，其中电器设备的选择主要包括：断路器、隔离开关、电压互感器、电流互感器、绝缘子、套管、电缆母线、避雷器等。关键词：变电站；一次系统；负荷计算；无功补偿；短路计算I2024 年 4 月 19 日下载后可任意编辑 Design of 110kV Substation and Primary System Abstract The design first to subject the original data analysis ， and II2024 年 4 月 19 日下载后可任意编辑substations loads computation and no work make the calculation. Then precede the burthen calculation of the transformer substation with have no the coefficient the in expiation of calculation the etc.. Secondly, according to the original data, for short terms and the choice, And according to short-circuit the result, a device would the checksum ；Complete the connection to choose the type and equipment designed to draw, when the substations a system. Finally, to prevent ground, ready for substations, and the electricity system in substations, Of electrical equipment chosen primarily includes ： breaker, isolated from a switch, voltage, potential transformer , current transformer, post-type insulator, bushing and cables etc., lightning arrester，bus etc.III2024 年 4 月 19 日下载后可任意编辑Keywords: Transformer Substation, The Primary System, load calculation ， Reactive power compensation ， Short-circuit calculation 目 录摘 要.....................................................................................................
