Transformer Rectifier

Product image

Ampcontrol’s high power rectiformers are designed and manufactured for the electrolytic production and refining of copper, zinc, magnesium, aluminium and nickel.

The rectiformers are also used in the production of chlorine, an important component of the chemical refining and pulp/paper processing industries.

Overview

Description

The rectiformer is a combination of a transformer and a rectifier in a single package.  Typical output ratings involve voltages ranging from 30VDC to 1000VDC with currents up to 120,000 Amps per unit.

The operation of the rectiformer is controlled by the double redundant, microprocessor based Integrated Control Electronics Module (ICEM), which controls the firing of the thyristors.  The self-monitoring capability of the module provides extensive diagnostics for detection, alarm and display of any fault.

Ampcontrol rectiformers feature high levels of redundancy and are designed to ensure high availability over the life of the plant.

Features include:

  • 100% redundancy in the thyristor firing circuits
  • Redundant thyristors – designed for an N-1 operational condition
  • Redundant parallel connected closed loop de ionised water cooling systems

The rectifiers are supplied fully factory assembled and tested thus requiring a minimum of installation at the site.

Features include:

  • Single way or bridge design
  • Six or twelve pulse operation
  • Microprocessor control using Ampcontrol’s Integrated Control Electronics Module
  • Surge and over voltage suppression
  • DC isolating switches
  • Optional harmonic filters available

Applications include:

  • Aluminium smelters
  • Copper electrowinning
  • Copper refining
  • Zinc refining
  • Nickel production
  • Chlorine and chlorate production
  • Large scale water chlorination
