Technical Field

The utility model relates to a current transformer technical field specifically is a large capacity current transformer is used in residence.

Background

The current transformer is an instrument for measuring by converting a large primary side current into a small secondary side current according to the electromagnetic induction principle. The current transformer is composed of a closed iron core and a winding. The primary side winding of the current transformer has few turns and is connected in series in a circuit of current to be measured, so that all current of the circuit always flows through the current transformer, the secondary side winding has more turns and is connected in series in a measuring instrument and a protection circuit, and when the current transformer works, the secondary side circuit of the current transformer is always closed, so that the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer converts a large current on the primary side into a small current on the secondary side for measurement, and the secondary side can not be opened.
