地埋式箱变在住宅小区应用设计.rar

摘要:随着居民生活水平的提高，城市现代化的加快建设箱式变电站在城市配电网中得以广泛的应用，但是在城市中心区建设的地上箱式变电站与当前的城市建设难以协调，与周边环境不和谐等因数。因此，地埋式箱变将作为一种新型节能型的箱变将会有很大的发展前景。

　　　本次毕业设计的主要内容是对住宅小区的供电系统的地埋式箱变、小区负荷计算、电力电缆的选择的初步设计，根据住宅供配电设计的相关规范进行设计。

　　　地埋式箱变是住宅小区供配电设计的重要组成部分，担负着改变电能和分配的重要任务。电力电缆担负着输送和分配电能的重要任务。因此，设计思路是：首先，根据小区情况计算负荷并分析结果，提出相应的供配电设计方案；其次，对小区的配线电缆进行选择。最后,绘制相关图纸。

Abstract:With the improvement of life level, the city modernization and accelerate the construction of box type substation in the city distribution network is widely used, but in the city center district construction ground box-type substation and the current city construction difficult to coordinate, and the surrounding environment is not harmonious factor. Therefore, a buried box type transformer substation will serve as a new type of energy saving of the case will have a great development prospect.

　　The graduation design is the main content of the residential quarters of the power supply system of underground box type transformer substation, area load calculation, selection of power cable based on the preliminary design, residential design for the distribution of relevant design specifications.

　　Underground box type transformer substation is residential supply and distribution is an important part of the design, responsible for changes in power and the distribution of the important task. Power cable load of power transmission and distribution is the important task. Therefore, the design thought is: first, according to the calculated load cell and the analysis of the results, and puts forward the corresponding power supply design scheme; secondly, on the district's distribution cable choice. Finally, draw relevant drawings.

Key words: Underground box type transformer substation， power cable， application
