摘要
分析了GIS变电站的特点,根据变电站的配置方案电气图,绘制出变电站系统的等值电路图,并计算出系统的短路点的冲击电流和稳态电流。考虑供电可靠性、变电站的经济性和发展空间,完成GIS系统内部的断路器、隔离开关、电流互感器、电压互感器、绝缘子、母线、氧化锌避雷器的选择、设计和校验,最终完成整套GIS设备的设计。
Analysis the features of GIS transformer substation,according to the configuration proposal electrical diagram,the equivalent circuit diagram of this transformer substation is drawn and the impact current and the steady state current of short dot in the system is calculated.Considering the reliability of power supply,economical efficiency of transformer substation and the development opportunities,the internal circuit breaker,isolator power switch,current mutual inductor,voltage mutual inductor,insulator,generatrix,zinc oxide arrester of GIS system are selected,designed and verified.The design of GIS equipment is completed finally.
