ABB DCV700 thyristor panels
Description
The DCV 700 series is a complete range of DC converters intended for the supply and control of DC machines, in stand-alone or multi-drive systems with high performance and reliability specifications.
DCV 700 converters are fully digital and mounted in an enclosure complete with all necessary equipment, meeting the most stringent safety standards. The converter can be used for standard applications but has the flexibility to be customized for the most demanding applications.
Comprehensive Product Range
DCV 700 converters are available as 6-/ and 12- pulse 2- or 4-quadrant, in a current range 22 to 5150/10300 A and supply voltages of 200 to 1000 VAC. A selection of options is available to provide the user with a system meeting the most demanding technical requirements and performance expectations. Common control electronics throughout the range reduces spare parts inventory and training requirements.
Digital Control
To meet the most stringent control requirements, the DCV 700 features speed control, which reduces the effects from gear backlash and torsional vibration arising in mechanical systems. High-performance speed and torque control will fulfill all requirements for rapid response and control accuracy. Autotuning for armature current control will simplify the commissioning procedure.
Wide Variety of Industrial Applications
The DCV 700 series can handle the most demanding applications in:
• rolling mills
• pulp and paper
• metals (casters, processing lines etc.)
• material handling (cranes, hoists etc.)
Diagnostics
Digital control allows comprehensive diagnostics, including for example detection of
• overcurrent
• overvoltage
• earth faults
Some of the most important features and benefits common to both the DC and AC drives are:
• application control system (APC) – fewer spare parts
• link to automation systems
• commissioning, maintenance and programming tools – less training
• control panel – quick information
• drive-MNS cabinets – standardization benefits; possibility to build mixed systems
• EMC design available
