More Information
Summary:The invention discloses a sawtooth-shaped opening and closing type small current sensor which comprises a magnetoelectric laminated material and a sawtooth-shaped magnetic core. The sawtooth-shaped magnetic core is of an isosceles sawtooth-shaped opening and closing structure or a non-isosceles sawtooth-shaped opening and closing structure, and the magnetoelectric laminated material is placed at an air gap of the sawtooth-shaped magnetic core through double-end clamping of the sawtooth-shaped magnetic core. Compared with a plain end opening and closing magnetic core and a tooth-shaped opening and closing magnetic core, the contact area of the opening and closing position of the magnetic core is effectively increased, the magnetic field intensity of the material position is improved, the magnetic field intensity of the isosceles sawtooth-shaped magnetic core at the laminated material position is about 0.15 T higher than the tooth-shaped section and is about 37% of the tooth-shaped section, the sensitivity of t
