There are a large number of rectifier, power converter, inverter, harmonic source, the safe operation of its produce higher harmonic can seriously harmother electrical equipment and system of main transformer. Filter reactor is widely used in high pressure wave in the cabinet, in series with the filter capacitor, tunedto a resonant frequency, used to absorb harmonic current corresponding frequency in grid, reactance rate of 1%, 5.67%, 6%, 12%, 13%, 3, 5, 7 can be eliminated, 11, 13 and higher harmonic wave. Filter reactor and capacitor are connected, not only can effectively absorb the harmonic wave in the power grid,the power factor of the system and improve, to a bigger role for the safe operation of the system on. Following its structural characteristics:

1 the filter reactor consists of three-phase and single-phase two, are the core dry type;

2 core with high-quality low loss cold-rolled silicon steel sheet, core is composed of a plurality of air gap is divided into uniform pieces, air gap epoxy glass cloth laminated board spacing, using special adhesive bonding, to ensure that the air gap reactance in operation process does not change;

The 3 coil with class F or class H flat copper wire wound, closely spaced anduniformly;

The coil and the iron core reactor 4 filter assembly body after pre drying, vacuum impregnation, baking and curing the process, using H level varnish, make the reactor coil and core tightly together;

The 5 filter reactor clamps, fasteners and other non-magnetic material, ensure that the reactor has high quality factor, ensure good filtering effect;

6 exposed parts are adopted for corrosion resistance.
Two, the implementation of standards

Standard 1.GB/T10229-1988 reactor
