Zusammenfassung:The utility model relates to a low-voltage side electronic current transformer with a shielding function. The electronic current transformer comprises a Rogowski coil and a low-power coil both coaxially overlapped and arranged on an inner bobbin bracket in a penetrating manner, wherein the inner bobbin bracket is fixed on an insulating support seat via an eversion edge at one end of the inner bobbin bracket; the Rogowski coil and the low-power coil as well as an outer bobbin bracket encircling the two coils are arranged on the eversion edge of the inner bobbin bracket in a supporting manner; the eversion edge is connected with an insulation grounded tube; and the inner and the outer bobbin brackets are all metal shielding bobbins. The electronic current transformer provided by the utility model adopts the Rogowski coil as a protection coil and the low-power coil as a measurement coil, and the two coils are overlapped on the insulating support seat; and the metal shielding bobbins are respectively arranged on
