<P>PROBLEM TO BE SOLVED: To solve a problem in which when a magnetic sensor is mounted on a substrate in a magnetic proportion system current sensor, the substrate should be arranged in parallel with a longitudinal direction of a bus bar and an installation angle cannot be changed, and thereby, it is difficult to integrate substrates arranged on a plurality of bus bars arranged in parallel with each other to one substrate. <P>SOLUTION: A current sensor 10 includes a sub bus bar 14 connected to a main bus bar 12 to be a current path. The sub bus bar 14 is connected to the main bus bar 12 so that a current measurement part 26 is extended at an angle different from a longitudinal direction La of the main bus bar 12. Thereby, a part of current flowing into the main bus bar 12 is branched to the sub bus bar 14. The current sensor 10 also includes: a core 16 formed like a partially notched annular shape and inserting the current measurement part into a hollow part 17; and a substrate 22 assembled with a magnetic sensor 20 and inserted into a gap part 18 of the core 16 together with the magnetic sensor 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
