1、中文摘要本毕业设计论文是光明60kV降压变电所电气部分初步设计。根据任务书的要求,对变压器进行选择包括:主变压器的台数、容量、型号等主要技术数据的确定;电气主接线主要介绍了电气主接先的重要性、设计依据、基本要求、各种接线形式的优缺点以及主接线的比较选择,并制定了适合要求的主接线;短路电流计算是最重要的环节,本论文详细的介绍了短路电流计算的目的、假定条件、一般规定、元件参数的计算、网络变换、以及各短路点的计算等知识;高压电气设备的选择包括母线、高压断路器、隔离开关、电流互感器、电压互感器的选择原则和要求,并对这些设备进行校验和产品相关介绍。而根据
2、本论文所介绍的高压配电装置的设计原则、要求对60kV、10kV的配电装置,决定此次设计60kV侧采用分相中型布置、10kV侧采用屋内配电布置。继电保护和自动装置的规划,包括总则、自动装置、一般规定主变压器、线路、母线等设备的保护,而变电所的防雷保护则主要针对避雷针和避雷器的设计。此外,还绘制了变电所主接线、平面图、断面图。关键词:变电所短路计算电气设备无功补偿51AbstractThisgraduatedesignthesisisaGuangMing60kVdecliningtopresstochangetogiveorgetanelectri
