【正文】 摘要 本次畢業(yè)設計為 陽光花園小區(qū) 2樓電氣設計。在整個設計中，本人依據(jù)國家有關的設計規(guī)范和標準以及有關專業(yè)提供的設計資料，對這個工程的強電系統(tǒng)及弱電系統(tǒng)進行設計。 本次設計涵蓋了強電系統(tǒng)設計和弱電系統(tǒng)設計 ，其主要設計內(nèi)容有： 1. 低壓配電系統(tǒng)設計。 包括照明配電系統(tǒng)設計和電力插座系統(tǒng)設計。照明配電系統(tǒng)和電力插座系統(tǒng)電源電壓等級都為 380/220V。負荷計算采用需用系數(shù)法 2. 照明系統(tǒng)設計。以一般照明設計為主。照度標準以小康照度標準為參照，照度計算采用單位容量法。 3. 插座系統(tǒng)設計。電力插座系統(tǒng)分為多條回路，每條回路均設漏電斷路器保護，做到系統(tǒng)安全可靠。 4. 防雷與接地系統(tǒng)設計。屋頂設有避雷帶，戶內(nèi)衛(wèi)生間做等電位連接，采用 TNCS系統(tǒng)接地保護方式。 5. 通信系統(tǒng)。本工程電話、網(wǎng)絡系統(tǒng)合用一套設備，管線分別敷設。 6. 有線電視系統(tǒng)。本工程采用 682MHz 雙向傳輸系統(tǒng)，要求用戶電平滿足 68177。 4dB；圖象清晰度不低于 4 級。 在本次畢業(yè)設計當中共繪制了 17 張圖紙，其中一張 A1 手繪弱電系統(tǒng)圖， 3 張 A1打印圖（弱電平面圖，低壓配電系統(tǒng)圖，照明平面圖），其余皆為 A3 打印圖。 關鍵詞 ： 強電系統(tǒng)設計；弱電系統(tǒng)設計；防雷接地系統(tǒng)設計 Abstract The graduation design for the electrical design of Yangguang Huayuan village 2 building. In the design, In accordance with the design codes and standards of the state as well as the relevant professional to provide design information, this project on power supply system and the weak system design. The design covers both the strong power system design and the weak system design, the design of its main contents are: 1. lowvoltage distribution system design. Including lighting distribution system design and electrical outlet system design. Lighting distribution system and power outlet system supply voltage level are 380/ Calculation use the required load factor method. 2. lighting system design. Mainly to general lighting design. Illumination standards as a reference to a welloff standard illumination, Illumination calculation method use the unit capacity. 3. socket system design. Power socket system is divided into multiple loops, each loop located leakage circuit breaker protection, so that the system safe and reliable. 4. lightning protection and grounding system design. There are lighting protecting zone on the roof. Indoor toilets do equipotential connection, using TNCS system grounding protection. 5. munications systems. The project calls, work system bined with a set of equipment, pipelines were laid. 6. cable system. This project uses the 862MHz bidirectional transmission system that requires the user level meets 68 177。 4dB。 image resolution of not less than four. In this graduation project there are 17 drawings drew, in which Figure weak systems A1 handpainted, three A1 print map (weak plan, a lowvoltage distribution system diagram , lighting plan), the rest are A3 print map. Keywords: Strong power system design。 weak system design。 lightning protection and grounding system design I 目錄 第一章 前言 ................................................................................................................1 第二章 低壓配電系統(tǒng) ................................................................................................2 低壓配電系統(tǒng)概述 .................................................................................................2 設計一般規(guī)定 .......................................................................................................2 高層建筑低壓配電 ...............................................................................................2 低壓配電系統(tǒng)的配電要求 .....................................................................................3 低壓配電系統(tǒng)的接線方 式 .....................................................................................4 負荷等級的劃分 ......................................................................................................4 負荷計算 ..................................................................................................................5 負荷計算的意義 ...................................................................................................5 負荷計算的方法 ...................................................................................................5 本工程的負荷計算 ...............................................................................................8 導線的選擇 ............................................................................ 錯誤 !未定義書簽。 導線和電纜的選擇原則 ..................................................... 錯誤 !未定義書簽。 導線和電纜類型的選擇 .....................................................................................25 常見導線和電纜型號及其用途 .........................................................................27 第三章 電氣照明系統(tǒng)設計 ........................................................................................29 照明系統(tǒng)概述 ........................................................................................................29 照明方式和種類 ...................................................................................................29 照明方式： ........................................................................................................29 照明種類： ........................................................................................................29 照明系統(tǒng)的設計 ....................................................................................................30 設計的依據(jù)： .....................................................................................................30 設計中應注意的方面： .....................................................................................30 標志疏散照明的供電 .........................................................................................30 照度計算 ................................................................................................................31 利用系數(shù)法 .........................................................................................................31 II 單位容量法 .........................................................................................................34 本工程照度計算 ................................................................. 錯誤 !未定義書簽。 第四章 插座系統(tǒng)設計 ..............................................................................................43 設計原則及要求 ...................................................................................................43 插座設計 ...................
