铜排选用设计规范(断路器变压器匹配)

1、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；（35C）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：20kA25 kA31.5 kA40 kA63 kA80 kA210 mm2260 mm2330 mm2420 mm2660 mm2840 mm2四、

2、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 M299AHD13BX-400/31TMY40 X4550AHD13BX-600/31TMY50 X5756AHD13BX-1000/31TMY60 刈1160AHD13BX-1500/31TMY80 X101670A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
