Today, I have explained various knowledge about high-voltage ring main units (HV RMUs) to everyone. As we all know, HV RMUs play an important role in industrial development, so today I will also talk about their composition and manufacturing principle.
Composition of High-Voltage Ring Main Units
The components of HV RMUs include the body (iron core, windings, insulation, lead wires), transformer oil, oil tank and cooling device, voltage regulation device, protection devices (breather, explosion vent, gas relay, oil conservator, temperature measuring device, etc.), and outlet bushings.
Manufacturing Principle of High-Voltage Ring Main Units
In a generator, whether a coil moves through a magnetic field or a magnetic field moves through a fixed coil, an electromotive force can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the quantity of magnetic flux linked with the coil changes—this is the principle of mutual induction. An HV RMU is a device that utilizes electromagnetic mutual induction to transform voltage, current, and impedance.
