摘要
 該論文主要闡述了某高層教學樓各系統電氣設計的設計依據、原則和方法及設計選擇的結論。在低壓配電系統設計中，根據負荷等級，確定供電方式及系統方案。運用需要系數法進行負荷計算，并按照規定選擇保護電器、電線電纜，達到安全用電和節約能源的目的。在照明的設計中，本著節能的原則，選擇熒光燈為光源，通過照度計算，確定最佳光源數，為學生和老師們創造了一個良好的學習、工作環境。在消防系統的設計中，通過感煙、感溫探測器，手動火災報警按鈕，消防栓按鈕等消防電氣設備的布置、安裝的設計，實現了對各防火區域的防火監測，探測火災的發生。并實現消防聯動，當有火災時，探測、監控和手控系統發出火災信號，有各聯動裝置發出警報，進行防火隔離和啟動自動滅火系統，在疏散人員的同時進行自動滅火，控制、消除火災隱患，保障該樓內人員、財產的安全。在防雷接地設計中，根據國家規范，通過計算將本建筑物歸為三類防雷，按照三類防雷建筑要求設計。弱電的設計只簡單介紹了有線電視系統，廣播擴聲系統以及綜合布線系統。下篇則針對廣播擴聲系統進行了深入研究，主要為教學樓內的多功能廳、會議室的廣播擴聲系統設計做了詳細的設計方案。

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 teaching building. In my power distribution design, according to load rank, determination power supply way and system plan; Using needs the method of correlates to carry on the computation load, according to the stipulation choice protection electric appliance, the electric wire electric cable, achieved uses electricity safely and saves the energy goal. In the lighting system design, in line with the principle which conserves energy, chooses the fluorescent lamp is the photo source, through the degree of illumination computation, determined the best photo source number, has created one comfortably, the bright life, the leisure environment for the students and teachers . In the fire prevention system design, through the feeling smoke, the feeling warm detector, the manual fire reports to the police the button, fire prevention electrical equipment and so on hose saddle button arrangement, the installment design, has realized to each area of fire protection fire protection monitor, the survey fire occurrence. realization fire prevention linkage, when will have the fire, the survey, the monitoring and the hand-controller system will send out the fire signal, will have various system to send out the warning, will carry on the fire protection to isolate and to start the automatic fire fighting system, while will disperse personnel's to carry on the automatic fire fighting, the control, the elimination fire hidden danger, will safeguard in this building the personnel, the property safety. Earths in the anti-radar design, The building is the third category lightning through calculating  accord to the national standard in this design of the lightning and grounding, which will be designed by the requests of the third category lightning building . The part of the light current mainly including: CATV, Public Broadcasting System, and Premises Distribution System and so on. It is to research the broadcasting and sound system in the next chapter ,the main content is that a detailed design plan is completed for the multifunctional lobby of the teaching building; the broadcast and sound system of the meeting room.
