ELECTRIC CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/018306
Kind Code:
A1
Abstract:
Conductors (110a, 110b) of a first electric current sensor unit (100a) and a second electric current sensor unit (100b) are disposed parallel to and spaced apart from one another, and extend in the length direction of the conductors (110a, 110b). An arch-shaped portion (111) and an inverse arch-shaped portion (116) of the first electric current sensor unit (100a) are positioned offset, in the length direction, from the arch-shaped portion (111) and the inverse arch-shaped portion (116) of the second electric current sensor unit (100b), and thus, as viewed in the width direction, a first magnetic sensor element and a second magnetic sensor element of the first electric current sensor unit (100a) are each positioned to the outside of an opening portion of the second electric current sensor unit (100b), and a first magnetic sensor element and a second magnetic sensor element of the second electric current sensor unit (100b) are each positioned to the outside of an opening portion of the first electric current sensor unit (100a).
