Storage
Switchgear
If it is necessary to store the switchgear for any length of
time, the following precautions should prevent corrosion
or deterioration:
1. Remove factory-installed protective covering.
2. Check thoroughly for damage.
3. Store in a clean, dry, rodent-free location between
-30 °C and 40 °C.
WARNING
!
Remove all cartons, containers, and miscellaneous
packaging and packing material from inside the
switchgear sections before energizing any internal
heaters. To prevent fire, remove any plastic or
polyethylene shrouding from the switchgear
sections before energizing any internal heaters.
4. Provide protective coverings to prevent dirt, water, or other
foreign substances from entering the switchgear.
5. If dampness or condensation may be encountered in
the storage location, heaters must be placed inside
the switchgear sections to prevent moisture damage
Approximately 300 W of heat in each section is required.
CAUTION
If the space heaters are to be temporarily energized
from an external source, it is important to remove
the fuses on the secondary side of the control
power transformer. This precaution is to prevent
a feedback of higher voltage to other portions
of the equipment through the CPT primary.
SecoVac Vacuum Circuit Breakers
If circuit breakers are not to be placed into service at once,
remove them from their shipping cartons and thoroughly
inspect them for damage. If the circuit breakers are in
satisfactory condition, replace them in their shipping cartons
for storage. Do not remove the circuit breaker shipping
supports at this time.
Figure 2-6: SecoVac Vacuum Circuit Breakers
Store the circuit breakers in a clean, dry location in an upright
position. They must be properly supported to prevent bending
of the studs or damage to any of the circuit breaker parts.
Do not remove any protective grease until the circuit breakers
are ready to be installed. A plastic or canvas-type cover should
be provided to reduce the possibility of damage to the circuit
breakers due to dust and water.
