CORE-SEPARATED CURRENT-TRANSFORMER WITH BUCKING COIL

The utility model provides a current transformer, which can make the iron core be separated by variant material; can make one part of twice coil wrap around one part of the separated iron core to form fractional number turns compensation; can adopt the method that an upper iron core column and a lower iron corn column are additionally provided with short-circuited turns so as to further compensating error. The current transformer for iron core column is made of silicon steel sheet; the upper iron core column and the lower iron core column are sheathed with the current transformer of coils so as to improve accuracy of measurement; the utility model is adapted for production or the utility model is adapted for making old type products change into high-level products.
