Description
Three-phase reactors for frequency converters are designed for 3×400 V/230 V, 50 Hz networks. They are produced in accor-dance with ČSN EN 61 558-2-20 with insulation class F and a maximum ambient temperature of 40 °C. The reactor series is designed with rated current and inductance values shown in the table. Where higher inductance is required, the reactors can be connected in series. Line (input) reactors are connected before frequency converters and are powered by alternating sup-ply current for the converter with frequency given by the line frequency. They limit the converter influence on the grid by reduc-ing the higher harmonics content in the input current. Line reactors also improve protection against surge line overvoltage, increase network impedance, improve the power factor, and suppress peak currents and supply voltage deformation. If you require a reactor designed to match specific requirements, please specify: rated current In (A), rated thermal current Ith (A) or content of upper harmonics (effective value or %), frequency f (Hz), inductance L (mH) or voltage loss on the reactor Ux (V) and effective or peak linearity (saturation current) Isat (A), unless it is equal to the rated thermal current. Additional pa-rameters such as maximum loss can also be specified.
