| titleOfInvention | Dc current sensor |
| abstract | It is an object of the present invention to provide a sensitive DC current sensor which has a good detecting capability for a DC leakage breaker and the like, particularly, even for a micro-current variation with a simple construction, and is constituted such that, a hollow portion 52 which communicates in a circumferential direction through a detecting core 51 consisting of an annular soft magnetic material is formed, an excitation coil 53 which is wound in a circumferential direction is disposed in the hollow portion 52, and a detecting coil 54 which is wound in a toroidal shape around the detecting core 51 is disposed, whereby the detecting core 51 can be constructed to have a very good productivity, and by the effective arrangement of the excitation coil 53 and the detecting coil 54, effects by a coercive force peculiar to the soft magnetic material constituting the detecting core 51 and the effect of a leakage flux from the excitation coil 53 can be considerably reduced, for example, a micro-current of about 5 mA or lower can be detected very sensitively. |
