Features

Installation of a REACTOR is recommended, which can restrain a low-pass resonant circuit (usually below the 5th) harmonics to flow into capacitors.

Benefits

Reactors adopt three-phase three-column type structure:</p><p> </p><p>1. The gap of the iron core adopts epoxy resin impreged glass cloth laminated sheet as the spacer. High-impact binder is applied (high-temperature tolerance) to ensure that gaps of reactors do not change and there is no noise during the operation.</p><p>2. Coils are tightly wound with enameled flat wires to ensure tha t coils of reactors do not vibrate during the operation(foil winding is used when current is more than 100A).</p><p>3. Advanced low-loss silicon steel sheet is used. Fast punching mode is applied to ensure that products have high efficiency and low loss.</p>

Applications

Capacitors get easily affected and damaged by harmonic current, inrush current, and due to overvoltage in the reactive power compensation system.
Therefore, to avoid parallel resonance and the issue of amplified harmonic current, it is necessary to be in a series reactor along with the capacitors.
Reactors are applied to avoid excessive amplification of power grid harmonics and resonance resulting from the connection of capacitor banks to prolong the service time of capacitors.
