● 根据一次电流及一次母线的截面积等参数来选择对应规格的电流互感器,一次导线穿越互感器窗孔,打开翻盖,通过
压线片进行二次接线,二次接线引出后翻盖复位。计量电能可直接利用翻盖小孔加以铅封,以防窃电。
● 工作电流长期不超过1.1倍额定值,允许在1.2倍额定值时短时使用,时间不超过1h;
● 根据被测电流大小,选定额定电流比,一般被测电流不大于额定电流2/3,或者根据断路器的额定电流来选择额 定电
流比,或按GB/T50063-2008进行选择;
● 产品极性为减极性,表示为:一次接线标志P1、P2,相应二次接线标志S1、S2;S1表示P1的同名端,S2表示P2的同名端;
● 测量仪表接于S1、S2端上,此时所接回路的总负荷(阻抗)不应超过电流互感器的额定负荷,当安装仪表位置与电流
互感器相距甚远或回路负荷(阻抗)较大时,应优先选用二次电流为1A的电流互感器;
● 注意根据母排的规格和根数,选用相匹配窗口大小的电流互感器。
