• Control  Panel

RECTIFIER EQUIPMENT  PRIMARILY CONSISTS OF THE FOLLOWING:

 

1).   Linear, Plus / Minus type Vertical Rolling Contact Voltage Regulator:

 In our regulator we are using heavy section of electrolytic grade rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are also using self Lubricating Carbon Roller Assemblies instead of ordinary carbon brushes which offers more reliability and trouble free performance of the equipment.

 

-       The output DC  voltage  variation is step less by means of ON LOAD motorised regulator. We use vertical ROLLING CONTACT TYPE voltage regulator, wound with heavy section of copper strip, suitable for 100% continuous duty  cycle. The life of these  regulators is more than 25 years and have 4 - 5 % better efficiency in comparison to conventional dimmerstat type regulators.

 

-         Please  note  that Rectifiers manufactured by us,  we  are  using plus/minus type (+ 254 Volts OR + 440 Volts) Voltage regulator in "Q"  connection  -  which  means that  the  capacity  of  voltage regulator  required  in our Rectifier winding design  is  50%  in Star connected (+ 254 Volts) model and 30% in Delta connected  (+440  Volts)  than straight type (0-440 Volts)  voltage  regulator used by  conventional design rectifier winding.

 

-         With  Plus/Minus  type voltage regulator used  in  our  rectifier design, the capacity of Voltage Regulator used remains the same, but   the  brush  current  of  the  Regulator  reduces  and   the reliability of regulator increases. This results in  considerable saving in overall power losses of our Rectifier equipment.

 

2.)        MAIN TRANSFORMER WITH IPT & DIODES

• CORE :  In our transformer we are using CRGO lamination to minimize iron losses. The core is constructed from low loss, Cold rolled, grain oriented, annealed laminations of electrical sheet steel conforming to the latest international standards. Special frame is built in house for clamping the core to reduce the magnetic noise as well as making the whole structure rigid and robust. We are using CRGOLSSS of  M3 Grade.

 

• WINDINGS:  Coil are wound with paper covered electrolytic grade copper strip or synthetic enameled copper conductors. Cooling ducts are provided to keep the hot spot temperature as low as possible. Rigid connection support and coil clamping is provided to ensure high short circuit strength. Electrolytic Grade Copper or Synthetic  enameled  copper with Parallel winding on the   Sec. side to reduce the SKIN effect.  Make : HCL supplied by Harinam Wires.( As per I.S. 2026).
