39。 消防部分主要 內(nèi)容包括: 報(bào)警系統(tǒng)、聯(lián)動(dòng)系統(tǒng)的設(shè)計(jì)等。 強(qiáng)電部分主要內(nèi)容包括:低壓配電系統(tǒng)、照明系統(tǒng)及防雷接 地系統(tǒng)的設(shè)計(jì),其中包括負(fù)荷計(jì)算、 低壓電氣設(shè)備選擇 等。在現(xiàn)代化城市電網(wǎng)中,供配電系統(tǒng)一次接線設(shè)計(jì)顯得極為重要。河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 摘要 I 摘 要 本論文主要闡述了某辦公樓各系統(tǒng)電氣設(shè)計(jì)的設(shè)計(jì)依據(jù)、原則和方法及設(shè)計(jì)選擇的結(jié)論。 電能是現(xiàn)代工業(yè)生產(chǎn)的主要能源和動(dòng)力,在整個(gè)國(guó)民經(jīng)濟(jì)生活中應(yīng)用極為廣泛,不僅改善了人們的工作環(huán)境,而且大大提高了勞動(dòng)生產(chǎn)率及人們的生活質(zhì)量,電力系統(tǒng)要能夠很好地為生產(chǎn)生活服務(wù),并做好節(jié)能工作,就必須滿足安全可靠、優(yōu)質(zhì)經(jīng)濟(jì)的要求。 本論文共包括 6 章內(nèi)容,前四章主要包括強(qiáng)電部分設(shè)計(jì);第五、六章主要包括弱電部分及消防設(shè)計(jì)。 弱電部分主要內(nèi)容包括:有線電視、公共廣播系統(tǒng)、閉路電視監(jiān)控及綜合布線系統(tǒng)的設(shè)計(jì)。 本辦公樓電氣設(shè)計(jì)為畢業(yè)設(shè)計(jì),其目的是通過(guò)設(shè)計(jì)實(shí)踐,綜合運(yùn)用所學(xué)知識(shí),理論聯(lián)系實(shí)際,鍛煉獨(dú)立分析和解決建筑電氣設(shè)計(jì)問(wèn)題的能力,為未來(lái)的工作奠定堅(jiān)實(shí)的基礎(chǔ)。s lives, power system to perfectly for production and life service, and pletes the energy conservation work, we must meet the safe and reliable, highquality economy requirements. In modern city of power grids, powersupply once wiring design appears very important. The thesis includes six Chapters. Previous four Chapters are mostly about the design of the forceful electric power Part。 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 firefighting mainly including: the design of the warning system and linked system etc. 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. 【 Key words】 electrical design, safe and reliable, power supply and distribution system, emergency power 河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 目錄 目 錄 摘 要 ...............................................................
