The
Magnetic Ring Inductor consists of a magnetic ring, a coil and a magnetic conductor. A magnetic ring is a toroidal magnet, usually made of ferrite or magnetic nanocrystalline material, with high permeability and low magnetic loss. The coil is wound around the magnetic ring and the current is induced in the magnetic ring by the magnetic field generated by the coil. The magnetic conductor passes the magnetic field to the magnetic ring and converts the measured magnetic field into an electrical signal.
Ii. Features:
1, simple structure: magnetic ring inductor is composed of a small number of basic components, simple structure, low manufacturing cost.
2, small size: due to the use of magnetic ring as the core, the size of the magnetic ring inductor is relatively small, suitable for use in limited space occasions.
3, light weight: magnetic ring inductor is made of lightweight materials, light weight, easy to carry and install.
4, high reliability: magnetic ring inductor structure is simple, no mechanical moving parts, so it has high reliability and stability.
5, good linear performance: the current and magnetic field characteristics of the magnetic ring inductor are relatively linear, which can provide accurate measurement results.
Third, the working principle:
When the current passes through the coil, the magnetic field generated by the coil is induced into the magnetic ring. The permeability and shape of the magnetic ring affect the distribution of the magnetic field. By measuring the magnetic field in the magnetic ring, the amount of current passing through the coil can be determined. The working principle of
Magnetic Ring Inductors is based on ampere's law and magnetic induction law.
4. Application:
Magnetic ring
Inductors are widely used in current measurement, magnetic field detection and protection devices in power systems. In power systems, magnetic ring inductors can be used to measure the current in high-voltage lines, detect fault currents, and protect transformers.
