Current detection device and electricity meter |
摘要 |
A device including: a conductor through which a current to be measured flows; multiple coils arranged around the conductor; a first magnetic body provided to face one of end surfaces of each of the multiple coils and configured to magnetically short-circuit the multiple coils; and a second magnetic body provided to face another one of the end surfaces of each of the multiple coils, configured to magnetically short-circuit the multiple coils, and including through-holes through which coil wires from the multiple coils are passed, respectively, the through-holes being provided at positions facing the other end surfaces of the multiple coils, respectively. |

1. A current detection device comprising:
a conductor through which a current to be measured flows; two bobbin-wound coils arranged around the conductor; a first magnetic body provided to face one end surface of each of the two bobbin-wound coils and configured to magnetically short-circuit the two bobbin-wound coils, the first magnetic body being provided with a through-hole in between the end surfaces of the two bobbin-wound coils; and a second magnetic body provided to face another end surface of each of the two bobbin-wound coils and configured to magnetically short-circuit the two bobbin-wound coils, the second magnetic body being provided with a through-hole in between the end surfaces of the two bobbin-wound coils, wherein the two bobbin-wound coils have same shapes, the first magnetic body and the second magnetic body have same shapes, and output terminals from the two bobbin-wound coils are passed through either the through-hole of the first magnetic body or the through-hole of the second magnetic body. |
