High current plants and supplies for
electrolysis and arc furnaces:
|
|
We supply large DC
converters for steel melting furnaces (EAF). For the chemical industry and
different electrolysis plants we design water cooled rectifiers and
transformers. The plants will be laid out according to the local requirements.
We can supply rectifiers up to 1200 V and 40 kA in B6 connection or approx. 300
V and 60 kA with interphase transformers.. According to the requirements we can
supply rectfiers with thyristors or diodes. |

The central picture shows a rectifier with water
cooling as a star connected rack (half a three phase bridge) for 15 kA in B6
connection.

Drives for conveyor belts
|
|
The advantages of a conveyor belt with speed control::
|
|
*Instead of
slipring motors, squirrel cage motors should be used |
|
*The resistance
controller in the rotor circuit may be omitted |
|
*A complete
reserve drive for revision purposes can be omitted |
|
*A lower, more
economic belt configuration can be selected |
|
*The losses are
considerably lower |
|
*The
maintenance cost can be reduced, lesser failure and breakdown times |
|
*Roller, belt
and gear are subject to lower wear rate |
|
|
If existing conveyor belts are equipped with speed
controls and the slipring motor shall be retained, we
can offer an electronic speed control with a
subsynchronous thyristorized cascade (USK).. |

|
The Automation and SCADA System @120 is understood to be the
next-generation system to theproven A120/Compact Automation and SCADA
Technology.This guarantees long-term availability of this powerful
Automation platform.
The Automation and SCADA System @120 may be used for new systems,
especially also for migration and hence for securing the money invested in
existing systems. These components fit neatly into the existing I/O world of
the A120/Compact range of equipment. |

he
Automation and SCADA System @250 is understood to be the next-generation
system to the proven A120/Compact Automation and SCADA Technology. This
next-generationsystem provideslong-term availability of the @250 range as
the @250 system fits neatly into the I/O world of the A250 system. A re-fit
is usually done using existing I/O modules. This eliminates the need for
expensive I/O cabling, thus making a re-fit or an upgrade possible at less
and predictable cost. The new CPU ALU320 ensures long term availability of
automation technology components.

Since the foundation in 1887, AEG has built many power
plants worldwide, driven by water, gas, coal or nuclear. In the year 1969, AEG
and Siemens merged their power plant activities and founded KWU. AEG Industrial
Engineering provides service for all AEG power plants. The following picture
