Abstract

A magnetic gathering ring for a current sensor belongs to the technical field of current sensors. The invention solves the problems of large size and high cost of the magnetic gathering ring in the existing current sensor. The present invention includes four groups of annular magnetic rings with air gaps, the four circular magnetic rings have the same structure and size, and the circular magnetic rings include a single crystal silicon material magnetic ring body and a soft iron material layer. The soft iron material layer is plated on the outside of the main body of the monocrystalline silicon material magnetic ring, and the width of the soft iron material layer is smaller than the width of the main body of the single crystal silicon material magnetic ring; the four circular magnetic rings are bonded from top to bottom through the bonding process are sequentially combined into an integral structure; the positions of the air gaps of the four circular magnetic rings in the integral structure are all corresponding. The invention is suitable for use as a magnetic gathering ring of a current sensor.

Description

technical field [0001] The invention belongs to the technical field of current sensors. Background technique [0002] In recent years, with the continuous improvement of people's requirements for the working stability of electric motors for new energy vehicles, solar and wind power inverters, current sensors are widely used in new energy, intelligent transportation, industrial control, smart home appliances and smart grids, etc. Field measurements. The non-contact current sensor is mainly used for the measurement of large current. The working principle of this type of current sensor is: the magnetic field generated by the primary current is collected by the magnetic field gathering ring, and the Hall element placed in the magnetic field gathering ring collects the magnetic field. , to generate a Hall voltage proportional to the primary side magnetic field, and by measuring the size of the Hall voltage, the isolated detection of the primary side current can be realized.
