Abstract
The invention discloses an electromagnetic current impeder. The electromagnetic current impeder comprises a magnetic core and a wire, wherein the wire is wound on the magnetic core; and different power supply output interfaces corresponding to different voltage values or current values are formed at the different positions of the wire. When the electromagnetic current impeder is used, induced current can be generated in the wire wound on the magnetic core, according to the Lenz's law, a magnetic field generated by the induced current always attempts to prevent the original magnetic field from changing, namely the induced current in the wire wound on the magnetic core prevents the original current in an alternating current circuit from changing, and thus electromagnetic impedance is formed, and the phenomenon of super rated current in the alternating current circuit is effectively avoided. Furthermore, the different power supply output interfaces corresponding to the different voltage values or current values are formed at the different positions of the wire, so that the electromagnetic current impeder can be used in different alternating current circuits with different voltage values, and the application range of the electromagnetic current impeder is expanded. Furthermore, the electromagnetic current impeder can be used simultaneously by different electric equipment with the same rated voltage in the same circuit.
