220/110/10KV降压变电站一次回路设计
摘要
根据给定的原始资料,此次进行了220/110/10kV变电站的电气设计,其中主要为电气一次设计,没有涉及到二次部分,此次设计的主要目的是将我们大学三年来所学的理论知识与实践相结合,使我们了解一些工程方面的综合知识。这次设计主要包括了电气主接线的确定,主变压器和所用变压器的选择,短路电流的计算,主要电气设备的选择,如断路器,隔离开关,电流、电压互感器等;配电装置的选择。设计中我们涉及到一些方法和软件的应用,如:Visio画图软件的应用,短路电流计算方法的运用,经济分析的运用等。通过此次设计,我们完成了电气一次部分的设计,并对变电站的主要组成及设计过程有了一定的了解。

220 KV transformer substation electricity design
Abstract
Depended on the primal data, the main electrical wiring of the220/110/10kV the press substation is designed. The main purpose of this design is that the academic knowledge and practice learned in past three bine together. We understand many engineering know-how through this course. It basically includes the choice of the main electrical wiring, the selection of the main transformer and its self-transformer, the calculation of short-circuit electric current, the choice of the main electricity equipments. The main electricity equipments mainly include the circuit breaker, the insulation switch, the electric current transformer and the potential transformer and so on. We learned some knowledge, such as the application of puter software, the calculation method of the circuit-short current, economic analysis etc. Through the design of several weeks, pleted the electricity design of the substation, and had certain understanding about the design process of the substation.
Keyword: the main electrical wiring; transformer; short-circuit electric current; circuit breaker; electrical equipment
