Abstract
A current transformer according to the present invention may comprise a magnetic core, a secondary coil, and a magnetic flux compensation member. A main circuit of an air circuit breaker penetrates the magnetic core. In addition, the secondary coil is arranged to be adjacent to the magnetic core, and a secondary current is induced through a current flowing in the main circuit. In addition, the secondary coil supplies the induced secondary current to a relay. The magnetic flux compensation member may be coupled to the magnetic core so as to correct magnetic flux of the secondary coil.
Claims6
A current transformer comprising:
- a magnetic core through which a main circuit of an air circuit breaker passes;
- a secondary coil disposed adjacent to the magnetic core to induce a secondary current from a current flowing through the main circuit and to supply the secondary current to a relay;
- and
- a magnetic flux compensation member coupled to the magnetic core to compensate for the current induced from the secondary coil.
