Greasing of insulating parts
•
Evenly grease the silicone parts with assembly
paste GCE009098P0101
•
Use the quantities set out in the table
Component
Insulating part in busbar connection
Sealing plug in busbar bushing,
silicone part of voltage transformer,
voltage sensor,surge arresters, test
bushings and blanking plugs
Cleaning the sockets
•
Clean the mating piece of the silicone
part-the cable socket or busbar socket
with cable cleaner MAB as required and
allow it to dry. A light, clean film of
grease is permissible

•
As a rule, no gas work is necessary during
installation
Only have gas work performed by personnel
trained in the handling of SF

5.3 Foundation frame
(Figures 5/9, 5/10, 5/11)
Switchgear on a foundation frame.
The relevant data for the order in hand can be
found in the ABB documentation.
The single or multiple panel foundation frame
can be supplied with the switchgear. It is as a rule
laid by site personnel and should be aligned
and inspected under the supervision of a
responsible specialist.
The specifications of DIN 43 661 are also to be
maintained when laying the foundation frame,
in particular the evenness and straightness
tolerances as a condition for perfect switchgear
assembly.
Tolerance conditions for laying of the
frame to DIN 43 661, version A:
•
Evenness tolerance: +/-1 mm per metre
•
Straightness tolerance: max. 1 mm per metre,

but max. 2 mm for the

5.4 Erection and connection of the panels
(Figures 5/1 to 5/6)
Note
Do not walk on the top of the panels (rupture
point for pressure relief system!).
5.4.1 Preparatory work
•
Before joining up the panels, check the gas
pressure in each gas compartment witha
temperature compensated pressure gauge
(GCE0905091P101). The indication must be in
the green area of the scale on the measuring
instrument. If there is any deviation from the
specified pressure or if your site altitude is
greater than 1000 m, please contact us
•
Grease the upper surfaces of the foundation
frame (this facilitates erection and alignment
of the individual panels)
5.4.2 Erection of the switchgear
•
Erect the end panel of the switchgear at the
precise position specified on the foundation
frame
•
Remove the handling bracket (1.18)
•
Align the panel
•
Perform a final check on the aligned position
of the panel and fasten it to the foundation
frame
•
Remove the protective caps from the busbar
sockets (2.13)
•
Carefully check insulating parts (2.14) and
contact tubes (2.21) for any dirt, and clean if
necessary (see also section 5.2.2)
Note
Only prepare insulating parts and
contact tubes for the panel currently
being erected. Protect them from
contamination !
•
Evenly apply a thin coating of assembly paste
to the conical surfaces A of insulating parts
(2.14)
Note
Leave no ungreased areas on conical surface A.
•
Carefully insert bus connectors (2.21) and
insulating parts (2.14) into the busbar
sockets (2.13)
•
Slide the adjacent panel carefully and evenly
(without tipping) against the erected panel
in such a way that the bus connectors, insulating
parts and guide pins slide into the corresponding
bores without the use of force.
If necessary, align the panel.
•
As soon as the distance between the two panels
is so small that bolts (2.16) can be entered in
the bores in the erected panel, insert these,
each with nuts and dished washers respectively
