Abstract
A current sensor that can reduce an installation area and improve measurement accuracy has a busbar through which current to be measured flows and a magnetic sensor that detects a magnetic field component generated by the current flowing through the busbar. The busbar can have left and right through-holes which can change the flow of the current to be measured. The magnetic sensor can be mounted on the upper surface of the busbar and can be screw-fixed to the upper surface of the busbar using the left and right through-holes.
Claims1
A current sensor comprising:
- a bus bar operable to conduct a flow a current to be measured;
- a magnetic sensor operable to detect a magnetic field component generated by current flowing through the bus bar;
- the bus bar having a changer operable to change the flow of the current to be measured;
- the bus bar being formed in a rectangular shape having an upper surface, a lower surface, an upper side surface, a lower side surface, a left side surface, and a right side surface;
- the magnetic sensor being mounted on the upper surface of the bus bar;
- the current flowing through the busbar flows from the right side surface to the left side surface, or from the left side surface to the right side surface;
- the changer being composed of a protruding portion;
- and
- the protruding portion being integrally provided so as to protrude outwardly from the upper side surface and the lower side surface of the busbar, respectively.
