Not only the present city,and a new socialist surroundings of the residential area is beautiful with a professional design. Public facilities are plete. This is works for the end of the power system , to domestic load for small residential area . First Statistics Load of small residential,we must think many things. Including the electricity consumption of the local residential in recent years, and the trend of changes year by year. I also contrast with the electricity consumption of the developed city ,and the Situation of transformers that have constructed. These work is to avoid the waste of the power of electricity and the waste of investment . After the confirmition of lode, I ensure the capacity of the transformer. With the evelopment of the transformer,I choose the transformer that have a good price quality. Considering the characteristic of district and the greate development of boxtype electric substation ,It is good to divide the district to several zones. Every zone’s power is supplied by a boxtype electric substation. the mand is equiped by parallel capacitor,and one or two transformers that offer electric power to buildings nearby. In the field of address of transformer ,I follow electricity ordinanceand electrical safety mustn’t affect the normal life. When drawing the schematic diagram ,I consider the distribution of the domestic load and the direction of the roads , on the principle of high efficiency and save resources ,to optimize of the the respect of underground cable ,I follow the Cable Layingof electric power engineering handbook and other relating to national standards. the Short Circuit Current has been analyzed, Major equipment has beed tested and calibrated. lightning protective earthing system has been designed in a systematic way.Keywords: 進行了短路電流的計算,主要設備的選擇和校驗,及接地防雷的設計。在主接線方面充分結(jié)合了小區(qū)的負荷分布情況和道路的走向,本著高效,節(jié)約的原則確定了方案。其中總控制室配備無功補償,并且安裝一臺或兩臺油式變壓器來給附近的住宅樓供電。要緊跟變壓器的發(fā)展,采用性價比比較高的變壓器。還與一些大城市的戶平均用電水平進行了比較,以及已經(jīng)建設好的小區(qū)的變壓器的負荷情況來綜合考慮每戶應該規(guī)劃的負荷,以免造成電能的浪費和投資的增多。本次針對電力系統(tǒng)的末端,小區(qū)配電方面進行了模擬學習。摘要 隨著國民經(jīng)濟的不斷提高,城市化的步伐正在加快。不僅是目前的城市,還是社會主義新農(nóng)村,由經(jīng)
