<:;Ilhjert
to wear and tear and aging
The crucial variables influencing the condition of the breaker are:
number of short circuit interruptions
number of switcring operations
time in service
TheAEG
maintenance program takes these variables into consideration
by .offering
suitable
inspection,
maintenance
and
reconditioning
intervals.
Maintenance
and reconditioning
should be carried out according to
the following guidelines.
When equipment
is operated
in extreme ambient
conditions,
it is
advisable to shorten the inspection and maintenance
intervals.
Such-conditions
are the following:
permanent high ambient temperature
abrasive dust in the atmosphere
high dust content atmosphere
permanent high humidity
corrosive gas or vapors in the atmosphere
Due to the use of highly stable grease resp. dry self-lubricating
friction component~; the spring operating mechanisms
do not require
any mai ntenance unlder normal conditi ons.
Maintenance
and reconditioning
should preferably be carried out by-
AEG specialists.
Service personnel (an be thoroughly trained on the job in .courses
