1、摘要根据设计任务书的要求,本次设计为110kV变电所电气一次部分初步设计,并绘制电气主接线图及其他图纸。该变电站设有两台主变压器,站内主接线分为110kV、35kV、和10kV三个电压等级,各个电压等级分别采用桥形接线、单母线分段带旁母接线和单母线分段接线,设计包括电气的一次部分和二次部分的设计和计算。在一次部分中,要对电力系统和变电站进行总体分析,然后确定变电站电气主接线的形式,并在此过程中进行系统的无功补偿、短路电流计算以及电气设备的选择。在具体计算后,还要为建造变电站进行配电装置及电气总平面的布置设计,使建站合理化。在二次部分中,要综合考虑保护的方
2、式、系统运行的方式和短路点的选择,在此基础上进行整定计算。在设计过程中要绘制相关图纸,包括主接线等较重要图纸并掌握其内容。本次设计中进行了电气主接线的设计、短路电流计算、主要电气设备选择及校验(包括断路器、隔离开关、电流互感器、电压互感器、母线等)、各电压等级配电装置设计、直流系统设计以及防雷保护的配置。关键字变电所短路电流计算变压器电气设备AbstractRequestaccordingtodesignspecification,capitaltheconnectiondiagramdesigningthatthefirststepdesigns,an
