1、 电气设计规范低压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箱变中的站变柜。三、铜排选择原则：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；四、 内容：（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-200/31TMY253276AHD13BX-400/31TMY404506AHD13BX-600/31TMY505697AHD13B
2、X-1000/31TMY6081000AHD13BX-1500/31TMY80101540A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）10kVA14.5A19ATMY153BVR6mm2170A48A20kVA19A38ATMY153BVR10mm2170A65A30kVA43A56ATMY153BVR16mm2170A91A50kVA72A94ATMY153BVR25mm2170A120A80kV
