Dry Type Iron Core Series Reactor

Dry type iron core series reactor

Introduction:

1. Application of dry type iron core series reactor

In shunt compensation device, it is connected to the shunt capacitor in series and suppress the surge current

during operation of capacitor return circuit and form filtration circuit with the capacitor group and filter special

harmonic wave.

2. Structural feature of dry type iron core series reactor

(1)Adopting epoxy resin formed solid insulation structure, three-phase integrated, with silicon steel sheet as

magnetic medium, framework structure composed of iron yoke, high fill factor iron column (laminating or

radiating type). Its coil is composed of multiple encapsulations and shunt wound with multi-strand flat copper

conductor with small bore so as to effectively reduce the volume and loss;

(2)The reactor core and winding are not submerged into any liquid, its cooling mode is air self-cooling, free of

oil leak and is convenient for manufacturing and maintenance and operation.

(3)The reactor coil is shunt wound with multi-strand flat copper conductor of small bore so as to effectively

reduce the eddy current loss of the conductor under harmonic wave;

(4)Multiple encapsulated reactor coil encapsulated chamber has axial heat emission air flue, with perfect heat

dispersion.

(5)The reactor coil and iron core, after undergoing hot setting, have perfect electric insulation property and

mechanical property;

3. Technical feature of resin insulation dry type iron core series reactor

(1)The coil is made by casting of epoxy resin, with features of inflaming retarding, self extinguishing, free of

maintenance, high mechanical strength, anti-short circuit impact, high insulating strength, small partial

discharge, long service life;

(2)The making of the iron core adopts manufacturing technology of dry type transformer, with features of slight

vibration and low noise, little magnetic leakage, small electromagnetic interference;

(3)The integral structure of the product is compact, with small installation dimension and space;

(4)The technical specification of the product conforms to the requirements of the international standard IEC289-

88 and ministerial standard JB-5346-98, its technical performance is up to the current international level of the

similar products.
