施工工程临时用电施工组织设计方案

-1-临时用电施工方案一、工程概况1、项目名称：！！！！！！222工程；工程地点：！！！市中心城区A7-01地块；建设单位：！！！市市直机关事务管理局；设计单位：中信华南（集团）建筑设计院；监理单位：！！！房实建设工程监理有限公司；施工单位：1111施工有限公司；建设规模：总建筑面积约23931m2，其中地上20431m2，地下3500m2。2、本工地施工临时用电采用三相五线制供电系统，布置位置及线路走向参见临时配电系统图及现场平面图，采用三级配电，三级防护。由业主提供足够的电源，接驳位置在场地东角。3、工程结构施工时用电量达到最大，所以取结构施工时的用电量进行设计计算，其中混凝土施工时计划使用混凝土输送泵车进行。二、编制依据《低压配电设计规范》GB50054-95中国建筑工业出版社《建筑工程施工现场供电安全规范》GB50194-93中国建筑工业出版社《通用用电设备配电设计规范》GB50055-93中国建筑工业出版社《供配电系统设计规范》GB50052-95中国建筑工业出版社《施工现场临时用电安全技术规范》JGJ46-2005中国建筑工业出版社《建筑施工安全检查标准》JGJ59-99三、施工机具明细表-2-序号设备名称型号台数/单台容量总容量N/kW（电动机）N/kVA（焊机或照明）kWkVA1塔式起重机60131/55602钢筋调直机GQ40-131/443钢筋切断机WJ40-104/4164钢筋弯曲机VNI-1003/4125物料提升机ZJ-804/10406消防泵XBD6/15-80×34/15606抽水泵∮75mm2/6.6137潜水泵10/2.2228木工圆锯机MJ-1168/3249平板振动器ZF150-508/2.217.610插入振动器ZN-3512/1.113.211直流电焊机AX-320-14/1656-3-序号设备名称型号台数/单台容量总容量N/kW（电动机）N/kVA（焊机或照明）kWkVA12交流电焊机BX1-400-14/31.4125.613室内照明及办公临设动力用电3514室外照明3015生活临设动力4516生活临设照明25三、确定计算负荷短时或周期工作制电动机统一负载持续率下的设备有功功率Pe2=2Pr×ε1/2电焊机统一负载持续率下的设备有功功率Pe2=Sr×ε1/2×cosφ照明及办公、生活设施用电为设备的额定功率Pe2=Pe1设备的计算负荷：有功功率Pjs＝Kx×Pe2，无功功率Qjs＝Pjs×tgφPr-----电动机额定功率（kW）；Sr-----电焊机额定功率（kVA）；ε-----负载持续率cosφ-----功率因数；tgφ-----功率因数对应的正切值KX----需要系数设备名称设备型号设备额设负载功率功率同一负需要系计算负荷-4-定功率备数量持续率ε因数（cosφ）因数对应的正切值（tgφ）载持续率下的设备有功功率Pe2(kW)数（Kx）有功功率Pjs(kW)无功功率Qjs(kvar)塔式起重机QT80E5510.250.51.73550.158.2514.273钢筋调直机GQ40-134110.51.7340.140.560.9688钢筋切断机WJ40-104410.51.7340.142.243.8752钢筋弯曲机VNI-1003310.51.7330.141.262.1798物料提升机ZJ-8010210.51.73100.1535.19抽水泵6.6210.80.756.50.79.16.825潜水泵2.21010.80.752.20.715.411.55木工圆锯机MJ-1163810.551.51830.2569.108平板振动器ZF150-502.2810.850.622.20.814.088.7296插入振动器ZN-351.11210.850.621.10.810.566.5472直流电焊机AX-320-116410.61.33140.3519.626.068交流电焊机BX1-400-131.4410.61.3331.40.2531.441.762室内照明及办公临设动力用电35110.750.88250.922.519.8室外照明30110.750.88200.91815.84生活临设动力45110.750.88350.931.527.72生活临设照明25110.750.88150.913.511.88小计225.7237.2541总的计算负荷计算，干线同期系数取Kp=0.9总的有功功率Pjs=Kp∑Pjs＝0.9×225.7＝203.131kW总的无功功率Qjs＝Kp∑Qjs＝0.9×237.2541＝213.529kvar总的视在功率：Sjs=（Pis2+Qis2）1/2＝294.71kVA总的计算电流计算Ijs=Sjs/（(3)1/2×0.38）＝447.766A业主提供315kW的变压器能满足施工要求。-5-四、刀开关、漏电保护器、熔体、导线截面积的选择箱号设备名称设备额定功率Pe1(kW)功率因数（cosφ）需要系数（Kx）电动机的平均效率η容量S（kVA）计算电流Ijs(A)导线截面刀开关熔断器漏电保护器备注243＃消防泵150.810.7026.7940.703×6+2×4HK2-60/3DZ15L-63架空电线254＃消防泵150.810.7026.7940.703×6+2×4HK2-60/3DZ15L-63架空电线162＃消防泵150.810.7026.7940.703×6+2×4HK2-60/3DZ15L-63埋地电缆171＃消防泵150.810.7026.7940.703×6+2×4HK2-60/3DZ15L-63埋地电缆2钢筋对焊机(电弧)75175.00113.953×50+2×25HR6-160/3DZ20L-160埋地电缆6塔式起重机550.710.8691.36138.813×70+2×25HR6-200/3DZ20L-200埋地电缆20室内照明及办公临设动力用电250.75133.3350.643×16+2×10HR5-100/3DZ15L-63埋地电缆室外照明200.75126.6740.523×10+2×6HK2-60/3DZ15L-63箱汇总450.750.954.0082.043×25+2×16HR5-100/321生活临设动力350.7510.8654.2682.443×10+2×6HR5-100/3DZ15L-100架空电线生活临设照明150.75120.0030.393×6+2×4HK2-60/3DZ15L-63箱汇总500.750.960.0091.163×25+2×16HR5-100/3187＃插入振动器1.10.8510.861.502.293×2.5+2×1.5HD-100/3RC1A-10/6DZ15L-20埋地电缆8＃插入振动器1.10.8510.861.502.293×2.5+2×1.5HD-100/3RC1A-10/6DZ15L-209＃插1.10.8510.861.502.293×HD-100/3RC1A-10/6DZ15L-20-6-箱号设备名称设备额定功率Pe1(kW)功率因数（cosφ）需要系数（Kx）电动机的平均效率η容量S（kVA）计算电流Ijs(A)导线截面刀开关熔断器漏电保护器备注入振动器2.5+2×1.5支路汇总3.30.850.90.864.066.173×2.5+2×1.5DZ15L-325＃平板振动器2.20.8510.863.014.573×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-206＃平板振动器2.20.8510.863.014.573×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-20支路汇总4.40.850.90.865.428.233×2.5+2×1.5DZ15L-32箱汇总9.480.87.5811.523×4+2×2.5HK2-60/3191＃物料提升机100.510.8623.2635.333×6+2×4HD-100/3RC1A-60/60DZ15L-40埋地电缆1＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-202＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-203＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-204＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-205＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-20支路汇总110.80.90.8614.3921.863×4+2×2.5DZ15L-401＃抽水泵6.50.810.869.4514.353×2.5+2×1.5HD-100/3RC1A-60/40DZ15L-20箱汇总47.090.837.6757.243×25+2×16HR5-100/3222＃物料提升机100.510.8623.2635.333×6+2×4HD-100/3RC1A-60/60DZ15L-40架空电线6＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-207＃潜2.20.810.863.204.863×HD-100/3RC1A-10/10DZ15L-20-7-箱号设备名称设备额定功率Pe1(kW)功率因数（cosφ）需要系数（Kx）电动机的平均效率η容量S（kVA）计算电流Ijs(A)导线截面刀开关熔断器漏电保护器备注水泵2.5+2×1.58＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-209＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-2010＃潜水泵2.20.810.863.204.863×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-20支路汇总110.80.90.8614.3921.863×4+2×2.5DZ15L-402＃抽水泵6.50.810.869.4514.353×2.5+2×1.5HD-100/3RC1A-60/40DZ15L-20箱汇总47.090.837.6757.243×25+2×16HR5-100/32310＃插入振动器1.10.8510.861.502.293×2.5+2×1.5HD-100/3RC1A-10/6DZ15L-20架空电线11＃插入振动器1.10.8510.861.502.293×2.5+2×1.5HD-100/3RC1A-10/6DZ15L-2012＃插入振动器1.10.8510.861.502.293×2.5+2×1.5HD-100/3RC1A-10/6DZ15L-20支路汇总3.30.850.90.864.066.173×2.5+2×1.5DZ15L-327＃平板振动器2.20.8510.863.014.573×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-208＃平板振动器2.20.8510.863.014.573×2.5+2×1.5HD-100/3RC1A-10/10DZ15L-20支路汇总4.40.850.90.865.428.233×2.5+2×1.5DZ15L-32箱汇总9.480.87.5811.523×4+2×2.5HK2-60/31418#箱7.58埋地电缆19＃箱37.6720＃箱54箱汇总99.250.989.33135.723×50+2×25HR6-160/3DZ20L-1601521#箱60架-8-箱号设备名称设备额定功率Pe1(kW)功率因数（cosφ）需要系数（Kx）电动机的平均效率η容量S（kVA）计算电流
