摘 要:本論文主要闡述了北京新村社區(qū)服務(wù)中心各系統(tǒng)電氣設(shè)計的設(shè)計依據(jù)、原則和方法及設(shè)計選擇的結(jié)論。本論文共包括六章內(nèi)容,前四章主要包括強電部分設(shè)計;第五、六章主要包括弱電部分及消防設(shè)計。
強電部分主要內(nèi)容包括:提供配電系統(tǒng)、照明系統(tǒng)及防雷接地系統(tǒng)的設(shè)計,其中包括負荷計算等。
弱電部分主要內(nèi)容包括:有線電視、公共廣播系統(tǒng)及綜合布線系統(tǒng)的設(shè)計。
消防部分主要報警系統(tǒng)、聯(lián)動系統(tǒng)的設(shè)計等。
本次設(shè)計完成圖紙共18幅,繪圖采用AUTOCAD軟件繪制。
本電氣設(shè)計為畢業(yè)設(shè)計,其目的是通過設(shè)計實踐,綜合運用所學(xué)知識,理論聯(lián)系實際,鍛煉獨立分析和解決建筑電氣設(shè)計問題的能力,為未來的工作奠定堅實的基礎(chǔ)。
Abstract :This thesis mainly explains the electrical design basis ,principle, methods and the conclusion of the design choice in each system in the design of certain office building. The thesis includes six Chapters. previous four Chapters are mostly about the design of the forceful electric power Part ;Chapter 5 and 6 are mostly about the design of the light current and fire-fighting.
The part of the forceful electric power mainly including: the distribution system of the low voltage, lighting system and rounding for lightening systematical compose ,among others include load calculation, illumination calculation .
The part of the light current mainly including: CATV, Public Broadcasting System, Closed Circuit Monitoring TV and Premises Distribution System and so on.
The part of the fire-fighting mainly including:the design of the warning system and linked system etc.
The design adds up to 34 electric charts. Including 17 graphics for the forceful electric power parts ,9 graphics for the light current parts and 7 graphics for the fire-fighting parts. All drawn by AUTOCAD.
This electrical design of the office building is a graduation design,The purpose of this design is to give us a chance of synthetical usage of the knowledge we have learned. Besides, it can train our ability to analyze and solve practical problems in Construct electricity in dependently so that the theory is connected with practice and a solid base is made in favor of future work.
