SMOOTHING REACTORS

AREAS OF USAGE

Arc furnace reactors are series-connected reactors that are installed in the supply systems of arc furnace transformers to stabilize arc and limit the unstable arc furnace current and voltage.

 

ADVANTAGES

  • Perfect mechanical strength to withstand high short-circuit forces
  • Limited temperature rise enables longer lifetime
  • Special surface protection against UV and pollution class IV areas
  • Maintenance-free design
  • Air core
  • Dry type
  • Side by side, delta or vertical arrangement depending on space availability for air core reactors
  • Outdoor and indoor
  • Enclosures are available on demand
  • Aluminum or copper winding
  • RAL 7035 or other colors
  • - 40 ºC / + 55 ºC ambient temperature range
  • F class (155 ºC) or customer specific design
  • Fiberglass resin spacers are used in order to provide ease of cooling
  • AN (air-natural) cooling method

      Medium Voltage NSPB connects the generator-to-transformer and the transformer-to-switchgear of the small-capacity power plant or substation, as well as the transformer-to-switchgear or the switchgear-to-switchgear of various other industrial facilities or buildings.

       

      STANDARD

      IEC 60076-6 or depending on customer requirements.

       

      INSULATION

      • F class (155 ºC) film insulation and epoxy resin reinforced fiberglass
      • Insulating varnish & corrosion resistant paint

       

      SUPPORT STANDS

      Aluminum, hot dip galvanized steel or concrete support stands are designed for specific applications.

       

      TESTS

      All the routine tests are performed in accordance with IEC 60076-6 or other standards depending on customer request. Type test reports are availibale on request. All the tests reports are submitted to customer.

      Basic testing program includes some or all of the following tests:

      • Routine Tests (Inductance, Resistance, One Minute AC Insulation Voltage Withstand Test and Impulse Voltage Withstand Test)
      • Short Circuit Withstand Test
      • Temperature Rise Test
      • Sound Level Test
      • Seismic Test
       

       

      LOSSES

      All Kian Tajhiz reactors are computer designed in order to minimize investment and operating losses.

       

      QUALITY ASSURANCE

      Kian Tajhiz maintains a complete quality assurance program including ISO 9001 and other European and American Standards in it's manufacturing plant.

       

      INSTALLATION

      The height and the diameter of the reactor can be adjusted to customer specific needs in order to meet unusual space requirements.

      Complete installation guidelines are provided with the reactors in order to meet required magnetic clearances on close metallic structures. Each reactor is supplied with an installation guidelines that specifies minimum magnetic clearances for the reactor.
