Dry type iron core shunt reactor

Application of dry type iron core shunt reactor

In super high tension long range transmission system, it is connected to the low tension side or the tertiary coil

of the transformer in parallel and used as the capacitive charging current of the compensating line to limit the

system voltage rise and reduce the insulating requirement and ensure the reliability of the line.

Structural feature of dry type iron core shunt reactor

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

magnetic medium, framework structure composed of circular iron yoke, high fill factor radiating type iron

column. 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, thermal

endurance class F, free of oil leak, safety and is convenient for manufacturing and maintenance and operation.

(3)The magnetic flux adopts silicon steel sheet as magnetic medium, the magnetic loop is triangle magnetic

circuit structure. The iron core column is composed of the irradiating type discus and special stone air gap, a

solid integer undergoing epoxy hot setting so as to reduce iron eddy current loss and noise.

(4)The reactor winding is composed of multiple encapsulated coils; Each coil is wound with glass silk enameled

flat copper conductor, and the coil is insulated and encapsulated with epoxy resin and solidified by high

temperature. Since the reactor coil is wound with multi-flat copper conductor of small bore, thus it effectively

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

(5)The encapsulated chamber of the encapsulated reactor coil has axial heat emission air flue, with perfect heat

dispersion.

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

mechanical property;

Technical feature of resin insulation dry type iron core shunt 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
