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

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.diode

5、 Reason for malfunction:

Possible causes of faults in magnetic ring inductors include:

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.diode

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.

4. High temperature: In high temperature environments, the performance of inductors may be affected, resulting in inaccurate measurement results or inductors not functioning properly.diode

6、 Fault detection technology:

For fault detection of magnetic ring inductors, the following techniques can be used:

1. Insulation test: Use an insulation tester to perform insulation tests on the windings of inductors to detect insulation faults such as open circuits or short circuits in the windings.

2. Magnetic flux detection: By measuring the magnetic flux in the magnetic ring, it is determined whether the magnetic ring is damaged or whether the change in magnetic flux is within the normal range.diode
