The client provides two transformers with capacity of 1000KVA and 2000KVA respectively as power supply. During two tanks construction, the main equipmen6、t includes five tower cranes, three placing booms and two elevators. The construction needs large power supply, power coefficient is great. 2.供配電方式Method of Power Supply 由業主現場提供的1000KVA，2000KVA變壓器配電室低壓柜已設電度表，故在我方各個總配電柜不再設置。供電方式采用三相五線制TN-S系統。 為減少因停電對生產的影響面，故采用放射式的配電方式，即：從變壓器配電室低壓柜引出五個干線回路至施工現場五個總配電柜，7、分別供塔吊，地泵，升降機，施工照明以及機具用電，在總配電箱及開關箱，以及距離超過100m的箱內做重復接地，并與保護零線可靠聯接。工作零線和保護零線要嚴格區分，不得混用。所有機電設備的金屬外殼必須與保護零線做可靠聯接。對負荷比較大的塔吊、地泵、采用單獨回路配電，對距離較遠且負荷較小的機具可采用樹干式配電方式。As ammeter is attached in the low-voltage cabinet of 1000KVA, 2000KVA transformer distribution room provided by owner, we will not install any amm8、eter in main distribution cabinets. Power is to be provided in TN-S System with three phases five lines. In order to minish the impact of power off upon production, radial way of distribution is adopted, that is: to give out five main line circuits to site five main distribution panels from low-volt9、age cabinets, which respectively supply power for tower crane, concrete pump, elevator, construction lighting, machines and tools power. The main distribution box, switch box and the distance over 100m between distribution box and switch box should be earthed repeatedly and well connected to PE line10、. The N line should be strictly differentiated from PE line, cannot be used confusedly. The metal shells of all mechanic equipments should be well connected to PE line. The way of distribution in tower crane and pump with comparatively large load should be separate circuit. Nonetheless, the way of d11、istribution in machines and tools with long distance and lower load could be in trunk distribution. 施工現場：根據現場實際情況變壓器至現場總配電柜線路采用VV22電纜直埋的方式敷設，到塔吊、地泵的線路采用YCW電纜架空方式敷設至分配電柜，塔吊、地泵（布料機）設置獨立防水開關箱，去移動式設備電源線采用耐磨電纜。Jobsite: According to site circumstance, transformer to site main distribution cabinet is adopt12、ed with VV22 cable buried underground to crane, pump and placing boom. Circuit is adopted with YCWcable set up to secondary distribution cabinet. One water-proof switch box shall be used for each tower crane, concrete pump (placing boom). Meanwhile portable equipment is adopted with wear-resisting c13、able.現場開關箱的設置：沿罐體四周根據施工需要設立防水開關箱，供振動棒、施工照明等設備使用；由配電箱引至二級配電箱的電纜可通過繩子固定在模板操作平臺上，二級配電箱和開關箱將隨著罐體模板的提升而升高（提升過程中總電源應切斷），滿足施工生產用電的需要。Setting up of site switch box: Water-proof switch boxes around tank shall be installed as required for the construction equipment such as vibrator, lighting etc. Cable from m14、ain distribution box to secondary distribution box could be gone along with rope and fixed on the formwork platform. The secondary distribution box and switch box shall be moved up with the formwork lifting (the power shall be cut off during lifting) to satisfy demand for construction.3.配電箱和開關箱 Dist15、ribution Box and Switch Box配電箱、開關箱采用符合標準要求的金屬箱，固定式配電箱、開關箱的下底與地面的距離大于1.3m，小于1.5m，移動式配電箱、開關箱的下底與地面的距離大于0. 6m，小于1.5m；配電箱與開關箱的距離不得超過30m，開關箱與其控制的設備水平距離不得超過5m。配電箱與開關箱必須安裝在干燥，通風的場所。現場配電箱，統一作為防水防塵型。整個臨時配電系統采用兩級漏電保護。Metal box according with the specification shall be adopted for site distribution box and swi16、tch box. Distance of the bottom of fixed distribution box and switch box away from ground shall be from 1.3m to 1.5 m; distance of the bottom of moveable distribution box and switch box away from ground shall be from 0.6m to 1.5 m; distance of distribution box away from switch box should be less tha17、n 30 m; horizontal distance of switch box away from controlled equipment should be less than 5m. Distribution box and switch box should be arranged in dry and ventilated place. Site distribution box shall be water-proof and dust-proof. 2 levels leakage breaker shall be used in the site temporary pow18、er supply system.現場照明：Site Lighting夜間施工區照明采用防水碘鎢燈；罐體施工現場：在每臺塔吊上裝三盞3500W鏑燈用于現場夜間照明。由于鋼筋加工廠6#塔吊高度為20米，故采用1000W高壓鈉燈，可以保證照度。The waterproof iodine tungsten lamps shall be used for lighting in the construction area during night shift. Three 3500W dysprosium lamps are installed on each tower crane for site19、 lighting during night. Owing to 20m high of 6# crane tower at rebar process workshop, we use 1000W high-voltage natrium lamps to ensure the lighting.4.現場防雷保護 Site Lightning Protection在做塔吊基礎時，利用基礎部分主筋相互焊接并與塔吊基礎節和接地引出線焊接連通形成可靠的良好的電氣連接，采用腳手架鋼管作為接地極與接地引出線焊接，保證接地電阻小于4歐姆，若達不到要求，則需要增加接地極數量。When installing20、 crane foundation, choosing some main rebars welded each other connects with the anchor foot and earthing eduction to make good electrical connection. Scaffold tube to be used for electrode shall be welded with earthing eduction to ensure earthing resistance less than 10; otherwise the number of ele21、ctrode should be increased.5.施工用電負荷計算Calculation of Power Load During Construction主要設備用電量統計表Statistics of Power Load of Main Equipment序號S.N.設備名稱Equipments Name單機容量（功率）Unit Capacity (Power) 數量Quantity小計sub-total (kW)1號罐 Tank 11砼振動器Concrete Vibrator310302地泵Concrete Pump11033303塔吊Tower Crane12022404塔吊T22、ower Crane16011605升降機Elevator111116照明Lighting507壓力泵Force Pump7.517.58其它負荷Other Load202號罐 Tank 21砼振動器Concrete Vibrator310302地泵Concrete Pump11033303塔吊Tower Crane12022404升降機Elevator111115照明Lighting506壓力泵Force Pump7.517.57其它負荷Other Load206.電纜、漏電保護器選擇Selecting of Cable, Switch根據現場實際情況，對電氣設備進行分組，利用Excel電子23、表格計算。（見附頁1）Divide the electric equipment into groups according to jobsite actual conditions.
