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； （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：20kA25 kA31.5 kA40 kA 63 kA80 kA210 mm2260 mm2330 mm2420 mm2660 mm2840 mm2四、
