铜排选用设计规范格式

电气设计规范-4-低压铜排选用设计规范为减少设计人员在选择铜排时出现选择不合理、与元器件排头不适配或不能满足安全距离及动热稳定性要求的情况，方便生产施工，特制定本设计规范。适用于本公司设计生产的10kV欧变、环网柜、35kV/10kV箱变中的站变柜。1.满足载流量要求；2.满足安全距离，与元器件排头适配；3.满足动热稳定性；（一）低压隔离开关上下接头连接铜排规定：隔离开关型号选用铜排规格铜排对应载流量HD13BX-200/31TMY25×3276AHD13BX-400/31TMY40×4506AHD13BX-600/31TMY50×5697AHD13BX-1000/31TMY60×81000AHD13BX-1500/31TMY80×101540A注：1.无特殊情况，选择铜排时严格按照以上对应规格。2.汇流排规格应与隔离铜排规格相同。变压器低压主母线选择规定（客户特殊要求除外）：变压器容量(kVA)额定电流(A)选型参考电流(A)选择铜排（导线）规格(mm)对应载流量（A）10kVA14.5A19ATMY15×3BVR6mm2170A48A20kVA19A38ATMY15×3BVR10mm2170A65A30kVA43A56ATMY15×3BVR16mm2170A91A50kVA72A94ATMY15×3BVR25mm2170A120A80kVA115A150ATMY15×3BVR50mm2170A187A100kVA144A188ATMY20×3BVR70mm2223A231A125kVA180A234ATMY20×3BVR95mm2223A283A160kVA231A323ATMY30×4385A200kVA288A375ATMY40×4506A250kVA360A469ATMY40×4506A315kVA433A563ATMY50×5705A400kVA577A750ATMY60×6900A500kVA722A938ATMY60×81000A630kVA909A1182ATMY80×81420A800kVA1155A1501ATMY100×81770A1000kVA1443A1876ATMY100×102000A1250kVA1804A2345ATMY125×102390A1600kVA2310A3002A双TMY80×103100A注：在选择铜排时还应根据板型接头、相间距离等相关尺寸进行选择！（三）低压断路器铜排选择规定1、天津津低断路器型号框架电流额定电流排头宽度选择铜排规格(mm)铜排对应载流量125ATMY15×3170A140ATMY15×3170A160ATMY15×3170ACM1－225225A100A20mmTMY15×3170A125ATMY15×3170A140ATMY15×3170A160ATMY15×3170A180ATMY20×3223A200ATMY20×3223A225ATMY20×3223ACM1－250250A180A20mmTMY20×3223A200ATMY20×3223A225ATMY20×3223A250ATMY20×5270ACM1－400400A225A30mmTMY30×4385A250ATMY30×4385A315ATMY30×4385A350ATMY30×4385A400ATMY30×8495ACM1－630630A400A40mmTMY40×4506A500ATMY40×4506A630ATMY50×5705A3、施耐德断路器型号框架电流额定电流排头宽度选择铜排规格(mm)铜排对应载流量MTE04-16NMTE06-16SMT06-16N1（固定式、抽屉式）400A44mmTMY50×5705A630ATMY50×5705A800ATMY50×8825A1000A双TMY50×51114A1250A双TMY50×81303A1600A双TMY60×61740AMTE20-32NMTE20-32S（固定式、抽屉式）2000A2000A76mm双TMY80×62110A2500A双TMY80×82620A3200双TMY100×103610AMTE06-32HMT08-32N2、H、L（固定式、抽屉式）630A630A76mmTMY60×6928A800ATMY60×6928A1000ATMY80×81420A1250ATMY80×81420A1600ATMY80×101610A2000A双TMY80×62110A2500A双TMY80×82620A3200A双TMY100×103610ANSX100100A80A≤25mmTMY15×3170A100ATMY15×3170ANSX160160A80A≤25mmTMY15×3170A100ATMY15×3170A125ATMY15×3170A160ATMY15×3170ANSX250250A125A≤25mmTMY15×3170A160ATMY15×3170A200ATMY25×3276A250ATMY25×3276ANSX400400A250A≤32mmTMY25×3276A400ATMY30×8495ANSX630630A630A≤32mmTMY40×8660A2000kVA3*（3*100*10）+2
