摘 要 所谓供电，就是指学校、工厂、企业、用户等所需电能的供应和分配。 众所周知，电能是现代工业生产和人民生活的主要能源和动力，电能既容易由其他形式的能量转换而来，也容易转换为其他形式的能量以供应用。电能的输送和分配既简单经济，又便于控制、调节和测量，有利于实现生产过程过程自动化。因此，电能在现代工业生产及整个国民经济生活中应用极为广泛。 本设计是对10kV学校中心配电所的电气部分设计，设计中运用经济及技术比较的方法来确定电气主接线，运用标幺值法来进行短路电流计算，通过查阅课本和设计手册对主要设备和导体进行选择检验以及对高低压配置图、二次接线图的设计。 该设计为10kV中心配电所，变电所断路器 负荷开关 短路电流 变压器 继电保护 Xx大学xx届本科生毕业设计（论文） ABSTRACT The meaning of power supply is that the schools, factories, firms, users and other energy requirements in the supply and distribution. As we all know, power is the mainly source in the modern industrial production and people life ,the energy can easily converted from other forms of energy, and also easy conversion to other forms of energy supply; The transmission of electric energy distribution is simple economic and easy to control, regulate and measurement, and it is conducive to the production process automation. So, the power of modern industrial production and the national economy as a whole life and is widely applied. This is the schools of 10kV center distribution substation part of the design. in the design, we used the economic and technical comparison of methods to determine the main electrical connection, and use the short current calculation method for the calculation of short current, through the inspection manual and the design of books for major equipment and electrical conductors and high-low-voltage power distribution devices and a design of the second electrical connection . This is a 10kV center distribution substation part of the design .That transformer substation has four transformer of sets, two is 1000 kV·A and two 630 kV·A. To design the main electrical connection an electricity lord、short current、choice and check of main equipment(include circuit breaker、load break switch、disconnect switch、current transformer、potential transformer )，introduce the relay protection and count it. Key words: 10kV transform distribution substation; circuit breakers; load break switch; short current; transfo
