铜排选用设计规范一、目的：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。二、范围：适用于本公司设计生产的10kV欧变、环网柜、35kV/10kV箱变、35kV/10kV开关柜。三、铜排选择原则：1.满足载流量要求；（35℃）2.变压器对应额定电流按照1.1倍过载系数考虑。3.满足安全距离，与元器件排头适配；4.满足动热稳定性；开断电流和铜排截面积对应表：20kA25kA31.5kA40kA63kA80kA210mm2260mm2330mm2420mm2660mm2840mm2四、内容：（一）低压隔离开关上下接头连接铜排规定（需要考虑低压主进开关的容量和隔离开关所带负荷的总容量，若两者皆很小，且仍用的较大的隔离开关，可做出适当调整）：隔离开关型号选用铜排规格铜排对应载流量HD13BX-200/31TMY25×3299AHD13BX-400/31TMY40×4550AHD13BX-600/31TMY50×5756AHD13BX-1000/31TMY60×81160AHD13BX-1500/31TMY80×101670A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。（二）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）10kVA14.5A16ATMY15×3BVR6mm2185A48A20kVA19A21ATMY15×3BVR10mm2185A65A30kVA43A62ATMY15×3BVR16mm2185A91A50kVA72A80ATMY15×3BVR25mm2185A120A80kVA115A127ATMY15×3BVR50mm2185A187A100kVA144A159ATMY20×3BVR70mm2242A231A125kVA180A198ATMY20×3BVR95mm2242A283A160kVA231A255ATMY30×4418A200kVA288A317ATMY30×4418A250kVA360A396ATMY30×4418A315kVA433A477ATMY40×4550A400kVA577A635ATMY50×5756A500kVA722A759ATMY60×6990A630kVA909A1000ATMY60×81160A800kVA1155A1271ATMY80×81490A1000kVA1443A1588ATMY100×81830A1250kVA1804A1985ATMY100×102030A1600kVA2310A2541A双TMY80×82620A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！（50kVA以下的变压器可以考虑使用电缆，尽量不要使用铜排。）（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铜排规格(mm)载流量ATW30-630～2000（固定式、抽屉式）2000A630A60mmTMY60×6990A800ATMY60×6990A1000ATMY60×81160A1250ATMY80×61300A1600ATMY80×101670A2000A双TMY80×62110AATW30-2000～3200（固定式）3200A2000A86mm双TMY80×62110A2500A双TMY80×82620A2900A双TMY80×103100A3200A双TMY100×103610AATW30-2000～3200（抽屉式）3200A2000A100mmTMY100×102030A2500A双TMY100×83060A2900A双TMY100×83060A3200A双TMY100×103610AATM30－63W63A4010mmBV6mm256A50BV10mm277A63BV10mm277AATM30－100W100A63A15mmBV10mm2(TMY15×3)77A185A80ABV16mm2(TMY15×3)105A185A100ABV25mm2(TMY15×3)137A185AATM30－250W250A100A20mmTMY15×3185A125ATMY15×3185A140ATMY15×3185A160ATMY20×3242A180ATMY20×3242A200ATMY20×3242A225ATMY20×3242A250ATMY20×5242AATM30－400W400A250A28mmTMY30×4418A315ATMY30×4418A350ATMY30×4418A400ATMY30×8510AATM30-630W(800)630A(800A)400A40mmTMY40×4550A500ATMY40×4550A630ATMY40×6660A700ATMY50×5756A800A双TMY40×4869A2、常熟断路器型号框架电流额定电流排头宽度铜排规格(mm)载流量CW1-2000（固定式、抽屉式）2000A630A60mmTMY60×6990A800ATMY60×6990A1000ATMY60×81160A1250ATMY80×61300A1600ATMY80×101610A2000A双TMY80×62110ACW1-3200（固定式）3200A2000A80mm双TMY80×62110A2500A双TMY80×82620A2900A双TMY80×103100A3200A双TMY100×103610ACW1-3200（抽屉式）3200A2000A100mmTMY100×102030A2500A双TMY100×83060A2900A双TMY100×83060A3200A双TMY100×103610ACM1－100100A80A17.5mmTMY15×3185A100ATMY15×3185ACM1－160160A100A20mmTMY15×3185A125ATMY15×3185A140ATMY15×3185A160ATMY15×3185ACM1－225225A100A20mmTMY15×3185A125ATMY15×3185A140ATMY15×3185A160ATMY20×3242A180ATMY20×3242A200ATMY20×3242A225ATMY20×3242ACM1－250250A180A20mmTMY20×3242A200ATMY20×3242A225ATMY20×3242A250ATMY20×5270ACM1－400400A225A30mmTMY30×4418A250ATMY30×4418A315ATMY30×4418A350ATMY30×4418A400ATMY30×8510ACM1－630630A400A40mmTMY40×4550A500ATMY40×4550A630ATMY50×5756A3、施耐德断路器型号框架电流额定电流排头铜排规格载流量MTE04-16NMTE06-16SMT06-16N1（固定式、抽屉400A44mmTMY40×4550A630ATMY50×5756A800ATMY50×8825A1000A双TMY50×51194A式）1250A双TMY50×81303A1600A双TMY60×61740AMTE20-32NMTE20-32S（固定式、抽屉式）2000A2000A76mm76mm双TMY80×62110A2500A双TMY80×82620A3200双TMY100×103610AMTE06-32HMT08-32N2、H、L（固定式、抽屉式）630A630A76mmTMY50×5756A800ATMY60×6990A1000ATMY80×61300A1250ATMY80×61300A1600ATMY80×101670A2000A双TMY80×62110A2500A双TMY80×82620A3200A双TMY100×103610ANSX100100A80A≤25mmTMY15×3BV16mm2185A100ATMY15×3BVR25mm2185ANSX160160A80A≤25mmTMY15×3BV16mm2185A100ATMY15×3BVR25mm2185A125ATMY15×3BVR35mm2185A160ATMY15×3BVR50mm2185ANSX250250A125A≤25mmTMY15×3BVR35mm2185A160ATMY15×3BVR50mm2185A200ATMY20×3242A250ATMY25×3299ANSX400400A250A≤32mmTMY25×3299A400ATMY30×8510ANSX630630A630A≤32mm双TMY40×4869A4、西门子断路器型号框架电流额定电流排头宽度铜排规格(mm)载流量3WT-400~3200（固定式）400~3200630A60mmTMY50×5756A800ATMY60×6990A1000ATMY60×81160A1250ATMY60×101300A1600ATMY80×101670A2000A80mm双TMY80×62110A2500A双TMY80×82620A3200双TMY80×103100A3WT-400～3200（抽屉式）400~3200630A60mmTMY50×5756A800ATMY60×6990A1000ATMY60×81160A1250ATMY60×101300A1600ATMY80×101670A2000A80mm双TMY80×62110A2500A双TMY80×82620A3200A100mm双TMY100×83060AVT100100A80A≤25mmTMY15×3185A100ATMY15×3185AVT160160A80A≤30mmTMY15×3185A100ATMY15×3185A125ATMY15×3185A160ATMY15×3185AVT250250A125A≤35mmTMY15×3185A160ATMY15×3185A200ATMY20×3242A250ATMY25×3299AVT400400A250A≤43mmTMY25×3299A400ATMY30×84510AVT630630A630A≤70mmTMY50×5756A（四）开关柜类铜排选用规定;额定电流（A）开断电流（kA）铜排规格（mm）载流量（A）63020TMY50×5756A63025/31.5TMY60×6990A125020/25/31.5/40TMY80×61300A160025/31.5/40TMY100×8（安全距离不够时选择TMY80×10）1830A（1670A）200031.5/40TMY100×102030A250031.5/40双TMY80×82620A315031.5/40双TMY100×103610A400040/50双TMY125×104100A注：对于PT柜和站变柜，不用考虑热效应，铜排选择50×5即可（五）10kV、35kV箱变铜排选用参照表隔离开关:额定电流（A）开断电流（kA）铜排规格载流量63020TMY-50×5756A125040TMY-80×61300A2000（10040TMY-100×102030A搭接排）3150（125搭接排）40双TMY125×83400A断路器:额定电流（A）开断电流（kA）铜排规格载流量63020TMY-50×5756A63025/31.5TMY-60×6990A125020/25/31.5TMY-80×61300A160025/31.5/40TMY100×8（安全距离不够时选择TMY80×10）1830A（1670A）200025/31.5TMY-125×82110A315025/31.5双TMY125×83400A400040/50双TMY125×104100A注：对于PT柜和站变柜，不用考虑热效应，铜排选择50
