雄安新区220kv降压变电站电气部分初步设计 说明书（论文）+任务书+开题报告+cad图纸
摘 要
随着社会的进步，在我国社会经济迅猛发展的背景下，各地各处对电能的需求量日益增加，人们对供电质量也提出了更高更新的要求。电能被广泛的应用于工农业生产以及人民群众的日常生活中。电能可以方便的转换为其他形式的能源，例如机械能、热能、光能、磁能等。而变电站在电网中起着十分重要的作用，它是联系发电厂和用户电力的重要枢纽，是将电能从产品转变为商品的中间环节。它不仅能够确保整个电力系统的有效运行，还能够保证相关工作人员的人身安全。
本次毕业设计报告题目为雄安新区220KV降压变电站电气部分初步设计。报告将对变电站220KV降压电气系统的一次设计进行介绍，为工厂供电的220/110/10 KV变电站的初步设计，对其特点以及在变电工程设计中实行典型供电气设备、接线方案和主变压器的选择进行详细的分析，为工厂供电降压变电站的设计提供了一套可行的设计方案。

Abstract
With the progress of society, under the background of the rapid development of social economy in China, the demand for electric energy is increasing day by day, and people also put forward higher requirements for the quality of power supply. Electric energy is widely used in industrial and agricultural production and the daily life of the people. Electric energy can be easily converted into other forms of energy, such as mechanical energy, heat energy, light energy, magnetic energy and so on. Substation plays a very important role in the power grid. It is an important hub to connect the power plant and the user's power, and it is the intermediate link to transform the electric energy from the product to the commodity. It can not only ensure the effective operation of the whole power system, but also ensure the personal safety of the relevant staff.
This graduation design report title is Xiong an new area 220 KV step-down substation electrical part preliminary design. the report will introduce the primary design of the 220 KV buck-down electrical system in the substation, the preliminary design of the 220/110/10 KV substation that supplies power to the factory, and the detailed analysis of its characteristics and the selection of typical power supply gas equipment, wiring scheme and main transformer in the substation engineering design, which provides a set of feasible design schemes for the design of the factory power supply buck-down substation.
