摘要：本次的設(shè)計(jì)對(duì)象是某鐵路牽引變電所110/27.5kV電氣一次設(shè)計(jì)。鐵路牽引變電所在鐵路中擁有很重要的地位，對(duì)鐵路機(jī)車的運(yùn)行提供牽引能量。設(shè)計(jì)目的是為了將自己所學(xué)的專業(yè)知識(shí)運(yùn)用到實(shí)際生活中。同時(shí)增強(qiáng)自己的學(xué)識(shí)與自學(xué)能力。對(duì)鐵路牽引變電所電氣一次設(shè)計(jì)的基本方法有所了解。

　　　本設(shè)計(jì)是通過自學(xué)牽引變電所的相關(guān)知識(shí)，以及運(yùn)用了以往學(xué)習(xí)的專業(yè)知識(shí)，最終完成了某鐵路牽引變電所110/27.5kV電氣一次設(shè)計(jì)。本次設(shè)計(jì)是在華靜老師的悉心指導(dǎo)下完成的。一下是設(shè)計(jì)的主要內(nèi)容：

　　　根據(jù)條件選擇牽引變電所一次接線設(shè)計(jì)部分的接線方法，并畫出一次接線設(shè)計(jì)圖；

　　　根據(jù)設(shè)計(jì)條件進(jìn)行短路計(jì)算；

　　　根據(jù)設(shè)計(jì)條件進(jìn)行器材選擇和校驗(yàn)，并且進(jìn)行防雷計(jì)算；

　　　最終完成設(shè)計(jì)，并對(duì)工作過程加以分析。

　　　本次設(shè)計(jì)中除使用傳統(tǒng)方法外，還應(yīng)用了CAD畫圖軟件進(jìn)行繪圖。在有限的時(shí)間里完成了某鐵路牽引變電所110/27.5kV電氣一次設(shè)計(jì)，取得了比較滿意的效果，達(dá)到了預(yù)期的設(shè)計(jì)意圖。

　　　通過設(shè)計(jì)，學(xué)習(xí)到了牽引變電所的知識(shí)，以及器材校驗(yàn)的基本方法。

Abstract：This design object is a railway traction substation 110/27.5 kV electrical a design. Railway traction substation in railway has a very important position, to provide the railway locomotive running traction energy. The design purpose to be their own major knowledge applied to real life. At the same time enhance their learning and self-study ability. For railway traction substation electrical once understand the basic design method.

This design is through self-study traction substation of relevant knowledge, and the use of the previous study specialized knowledge, finally completed certain railway traction substation 110/27.5 kV electrical a design. This design is in HuaJing teacher of meticulous guidance finish. It is the design of the main content:

According to the condition choose traction substation a wiring design part of wiring method, and draw a connection design;

According to the design conditions are short circuit calculation;

According to the design conditions for equipment selection and calibration, and lightning protection calculation;

Final design, and the working process of the analysis.

This design in addition to the traditional method to use the application of CAD drawing software to drawing. In the limited time completed certain railway traction substation 110/27.5 kV electrical a design, has obtained the satisfactory effect, achieve the expected design intent.

Through the design, learning to traction substation of knowledge, as well as the basic method of the equipment calibration.

Keywords: Traction substation; The factory power supply; High technology; The bridge connection.
