摘要:本設計的主要內容包括電力、照明、防雷接地、電視電話、網絡等系統,以及配電系統、負荷計算、供電電源和電壓的選擇和設備選型。

   其中電力系統主要包括確定電壓等級、供電方式。負荷計算主要是確定導線截面、型號和斷路器等配電設備的選型。

   照明系統主要包括照度計算,照明光源類型和燈具型號的選擇,確定燈具的布置方案和照度計算。 

   接地防雷的設計中,采用避雷帶保護方式。通過扁鋼與地基鋼筋結構相接,防雷、接地公用接地體,既保障了接地安全,又節約了接地設備。

   有線電視、電話及網絡系統設計:有線電視器件的選擇與計算一定滿足用戶端所規定的電平值,采用分配——分支結構進行有線電視信號的分配。電話系統采用電話分線箱分配方式。弱電主要是做好預留預埋,由其他部門施工調試?! ?/p>

關鍵詞:電力系統;照明系統;防雷系統;弱電系統;負荷計算

 

Abstract:Main content that design originally include electricity , illumination , defend system , video telephone , network ,etc. of fire control, the choices of the power and voltage and equipment selecting type that and calculate , supply power in distribution system , load. 

   Among them the power system includes confirming the grade of voltage, power supply way mainly. Load is calculated to be mainly a selecting type of confirming such distribution equipment as wire section, the type and circuit breaker, etc. 

   Lighting system include intensity of illumination calculate lamps and the lamp the light source, making sure the lamp arranging project, the choice of illuminating circuit and the choose of protection, socket of quantity mainly.

   Lightning protection the lighting fence is a possible lighting protection approach. Through the flat steel reinforced structure and the foundation phase, lightning protection, grounding the common ground, while ensuring the safety of the grounding and grounding equipment savings.

   CATV system design: The choice of the cable television. Equipment and the calculation must attain the provision value. The system adopts and assigns the branched structure which carries on the distribution of the wired TV signal. Sub-line telephone system uses the telephone box pattern to meet user requirements. The weak electricity is mainly done well and reserved burying in advance, is constructed and debugged by other departments.

Key words:Power system;Lighting;Lightning protection system;Weak current system;Load calculation

 

   隨著高層建筑的不斷興建,用電設備增加,特別是在高層建筑內,空調及電梯負荷的大量使用是電力負荷發生很大變化的一個很重要的因素。如果還按過去僅有照明來統計,計算結果將會使所選的開關及導線截面均偏小,所配置的電表容量偏小,造成經常性的負荷跳閘,超負荷運行而燒壞開關、電表、電線的現象常有發生。準確計算出住宅小區的用電負荷,合理選擇配變電設施,才能既滿足小區居民現在及將來的用電需要,又能合理降低工程造價、節省投資。
