What is a magnetic ring inductor? The basic structure, characteristics, working principle, applications, fault causes, fault detection technology, and market prospects of magnetic ring inductors 2

3、 Working principle:

When current passes through a coil, the magnetic field generated by the coil will be induced into the magnetic ring. The magnetic permeability and shape of a magnetic ring can affect the distribution of the magnetic field. By measuring the magnetic field in the magnetic ring, the magnitude of the current passing through the coil can be determined. The working principle of magnetic ring inductors is based on Ampere's law and the law of magnetic induction.diode

4、 Application:

Magnetic ring inductors are widely used in current measurement, magnetic field detection, and protection devices in power systems. In the power system, magnetic ring inductors can be used to measure current in high-voltage lines, detect fault currents, and protect equipment such as transformers.

5、 Reason for malfunction:

Possible causes of faults in magnetic ring inductors include:diode

1. Winding open circuit or short circuit: The wires in the winding may be loose, damaged, or short circuited, causing the current to not pass through properly, resulting in the inductor not working.diode

2. Magnetic ring damage: As the core component of the magnetic core, the magnetic ring may be damaged by factors such as impact, pressure, or high temperature, resulting in changes in magnetic flux and affecting the measurement accuracy of the inductor.

3. Overload or overvoltage: If the current or voltage measured by the inductor exceeds its rated range, it may cause damage to the inductor or inaccurate measurement results.diode
