Current source converters for medium voltage

Überblick

Our current source converters are robust devices designed for continuous drive operation with speed-control or as soft-starter converters for large synchronous machines.

By using proven thyristor technology and simple, compact device construction, we achieve the highest levels of availability while keeping required maintenance to a minimum.


Characteristics

Max. rated voltage: 10 kV

Max. rated current: 1 kA

Applications: Synchronous machines

Suitable for: short-term or continuous operation

 


Bedienung

Operation

Medium-voltage power converters can be controlled remotely. A variety of communications protocols are available, or, alternately, a galvanic interface can be used.

Parameters can be conveniently adjusted with a web-browser panel.

Signal lamps mounted on the control compartment access panel provide rapid feedback on system status.

For commissioning, service, and diagnosis, a display panel is integrated into the access panel of the control compartment for a user-friendly visualization of operational modes and chronology.


Operator protection

Separate low-voltage compartment

A dedicated low-voltage compartment for system control is completely sealed off from the medium-voltage equipment. Access of this compartment is possible during operation.

Galvanic isolation

Isolation is provided between the high-power equipment and controls via fiber-optic connections.

Latching push-knobs

Prevent inadvertant opening of access panels.

Type-tested enclosure system

The power equipment is housed in type-tested medium-voltage enclosures.

Emergency stop

Mounted externally and on the compartment access panel.

Access panel monitoring

Emergency stop when the panel is opened.

 


Options

Further options are available on request.

Integrated machine protection

Modular switch panels

Expandable field automation, machine monitoring

Extended user controls for singular installations or drive groups, up to and including the supervisory SCADA system

Communications interfaces PROFINET, MODBUS TCP, IEC 60870-5-104, IEC 61850, etc.
