摘要
随着社会不断进步,人们的生活水平不断提高,人们对供电质量的要求也越来越高。供电质量指标有:供电稳固性、供电可靠性和供电持续性。为了达到人们对供电质量追求的目标,变电站设计在其中起了不可替代的作用。论文题为电机制造厂35KV变电所一次系统设计。设计了一个35kV总降变电所,该变电站共有两个电压等级: 35kV和10kV。设计思路如下:进行负荷计算,选择主变型号,选择主接线方案,计算短路电流,根据短路电流计算结果和主接线方案选择各类电气设备(如:断路器、电流互感器、电压互感器、母线、避雷器等),设计变电所布置图,厂区供电系统平面图,编写材料清单。力求做到运行可靠,操作简单、方便,经济合理,具有扩建的可能性和改变运行方式时的灵活性。使其更加贴合实际,更具现实意义。

Abstract
Along with the social progress, people's life standards improve, people have higher requirement for the quality of power supply. The quality of power supply contains: stability of power supply; reliability of power supply and continuity of power supply. In order to meet people’s requirements of power supply, design of transformer substation plays irreplaceable role. Thesis topic is to design motor factory substation first side system. The substation has two voltage levels: 35 KV and 10 KV. Ideas of the design are as follows: First do load calculation. Second select the main transformer model according to the load calculation. Third select the main wiring scheme. Fourth to calculate the short-circuit current based on the main wiring scheme. At last to choose types of electrical equipments (such as: circuit breakers, current transformers, voltage transformers, bus, surge arresters and so on) according to the results of the short-circuit current and the main wiring scheme, design the substation layout and the factory layout, write the material list.
In order to make it reliable to operate, easy and simple to manipulate, economical, with the possibility of expansion and flexibility of changing its operation. As to make it more actual and practical significant.
Key words :Motor factory 35KV the total drop substation design equipment selection
