Application Fields
Electrical railways, metallurgy, petrochemical and other enterprise power distribution, used for high-order harmonic suppression and dynamic reactive power compensation (taking into account compactness and low loss characteristics).
Usage
Used in parallel capacitor circuits to limit closing inrush current during switching; used in high voltage parallel circuits of power systems to compensate capacitive current of transmission lines.
Main Technical Parameters
Rated Voltage: 6~35kV Rated Capacity: 10~10000kvar
Product Features
Dry-type semi-iron-core reactor features: There is an iron core inside the coil, so the magnetic permeability of the reactor is greatly increased. Under the same inductance, the reactor volume is about 50% of that of an air-core reactor; the loss is 30% lower than that of an air-core reactor; the installation size is small, about 60% of that of an air-core reactor.
Magnetic shielded reactor features: There is a cylindrical iron core on the outer layer of the coil, so axial leakage flux is almost completely confined to the iron core, so interference from axial leakage flux does not need to be considered; because there is no iron yoke, the inductance linearity is good and it is extremely difficult to saturate; the loss is 40% lower than that of an air-core reactor; the installation size is small, about 50% of that of an air-core reactor.
