Печатать страницуOutdoor devices Fla 15/60 GB R N and Flc GB R N are disconnectors not demanding for maintenance.
If the disconnector is in switched-off position for a long time (longer than one year), it is recommended making
several no-load manipulations in order to clean the contact joints and to check the mechanical operation of the
drive.
A. In the case of a round once a year – inspection using binoculars:
•
Checking visible faults of contacts (burn-offs, distorted contacts).
•
Inspection of the condition of insulators.
•
Inspection of the integrity of the operating mechanism.
B. In the case of a climbing inspection according to the preventive maintenance plan – at least once for 20 years
(10 years for remotely controlled devices), the following operations must be carried out:
•
Check of the correct switching function of the device by switching on and off several times.
•
Inspection of the condition of contacts (burn-offs) or replacement, if necessary.
•
Check of the correct setting of the device.
•
Cleaning contacts with a dissolvent or degreasing agent.
•
Lubricating contacts (grease Barrierta L 55/1 from Klüber Lubrikation, Germany).
! CAUTION ! Contacts must not be lubricated with any other grease!
•
Check of the run of all bearings and articulated joints and their lubrication (Omnigliss – Spray from Dow
Corning).
•
Inspection of insulators for possible damage.
•
Cleaning insulators if fouled.
In the case of disconnectors Fla 15/60, an oil condition check is possible. The oil condition check is carried out if
there is a suspicion of oil leakage. At this check, the bleeder plug must only be set, not screwed in. The oil level
must be between the two lines on the bleeder plug gauge. Each quenching chamber contains approx. 0.5 L of oil.
In the case of manually operated disconnectors Fla 15/60 it is recommended, after twenty years, to inspect the
chambers connected with renovation. Renovation is performed at the manufacturer and it includes oil change and
seal replacement, check and, if necessary, replacement of other parts. In the case of remotely controlled devices,
we recommend renovating the chambers due to the anticipated higher operating load after ten years at the latest.
In the case of already renovated quenching chambers, such inspection is recommended after ten years. The
renovation of chambers is performed using the exchange method – in this way the lock-out time is only limited
practically to the time necessary for dismantling old and mounting new chambers.
The same warranty is given to chambers renovated by manufacturer as to new chambers. The
manufacturer also provides free ecological disposal of used oil.
Specifications are subject to change without notice.
