Functional Compartments

Configuration of the Drawer Unit Compartment:

Depending on the panel type, the drawer unit compartment can be equipped with the following units:

-  Vacuum circuit-breaker
-  Vacuum load-break switch
-  Vacuum contactor (incl. HRC fuse base)
-  Disconnecting link
-  Busbar earthing switch

Positively actuated metal shutters protect against unintentional touching of the fixed contacts when the drawer unit is in the disconnected position. An auxiliary carriage is available for taking out and inserting the drawer unit; in other words the carriage is interlocked with the panel while handling.

Mechanical actuation of the switches and operation of the drawer units when the metal-clad compartment is closed is provided by actuating controls at the compartment door.

Optional motorised drives for the switches and the drawer movement are available so that fully remote control can be implemented. Optionally, in the metering panel current and voltage transformers according to DIN 42600 part 8 and part 9 respectivelly can be fixed mounted instead of the drawer unit. In the bus sectionaliser riser panel versions the compartment can remain unequipped without bushings and shutters.

 

 

Configuration of the Busbar Compartment:

The busbar compartment is equipped with copper busbars sized according to the panel rating. The busbars can be linked from panel to panel. Inside, the busbars are mounted phase-wise on insulators, so that panels can be easily and quickly assembled into a row. The busbar supports can optionally be assembled with a capacitive system for voltage measuring according to IEC 61243-5. The partitioning of the busbar compartment is provided with bushings for panel-to-panel connections.

 

 

Configuration of the Cable Connection Compartment:

The cable connection compartment offers a multitude of standard and requested equipment with:

Current and voltage transformers
Voltage transformers with primary fuses
Earthing switch
Surge arrestor
Three-phase medium voltage capacitor
-  HRC fuse base

Depending on the panel version from three cable systems up to six cables per phase can be connected in panels. The panel floor is sheet-metal.

In the bus sectionaliser panel versions, the compartment contains the section busbars. For connections through the side, flat profile copper busbars are used as in the busbar compartment. Inside, the busbars are mounted phase-wise on insulators, so that panels can be easily and quickly assembled into a row.

Optionally, a capacitive system for voltage measuring according to IEC 61243-5 can be mounted in the busbar compartment.

 

 

Configuration of Low Voltage Compartment (Relay Enclosure):

The low voltage compartment is designed as a separate assembly and can be removed from the switchgear panel. The configuration with protection and control systems is arranged functionally for the respective application. Application-related standards such as those for outgoing panels with overcurrent protection, differential protection, motor protection etc. provide a secure project planning basis for the consultant.

All usual protection and control systems can be assembled.

Also equipment supplied by the customer can be used.
