4. Manipularea echipamentelor
Inainte de manipularea intrerupatoarelor se verifica pozitia
deschis a acestuia si starea nearmat a arcului mecanis-
mului de actionare.
Intrerupatoare cu tensiunea nominala de pana la 24 kV
– Pentru ridicarea si manuirea intrerupatorului, se folosesc
carligele (1) (fig. 2a).
– Agatarea carligelor (2) se face in gaurile cu care este
prevazut intrerupatorul.
– Al termine dell’operazione (ed in ogni caso prima della
messa in servizio) sganciare l’attrezzo di sollevamento (1)
(fig. 2b) e smontare la traversa (2) svitando le viti (3).
Intrerupatoare cu tensiunea nominala de pana la 36 kV
– Se foloseste dispozitivul (1) pentru ridicarea si manuirea
intrerupatorului (fig. 2c).
– Se agata carligele (2) ca in fig. 2d si se ridica;
– La terminarea operatiei se inlatura dispozitivul (1).
Intotdeauna trebuie acordata o atentie deosebita pentru a nu
fi afectate partile izolante ale intrerupatorului.
La manuirea aparatului nu se vor folosii
unelte cu care ridicarea se face altfel decat ceea ce
s-a prezentat mai sus.
4. Handling
Before carrying out any operation, always check that the
operating mechanism springs are discharged and that the
apparatus is in the open position.
Circuit-breakers up to 24 kV
– To lift and handle the circuit-breaker, use the tool (1) (fig. 2a).
– Put the hooks (2) in the holes prepared in the circuit-breaker
frame and lift.
– On completion of the operation (and in any case before
putting into service) unhook the lifting tool (1) (fig. 2b) and
dismantle the crosspiece (2) by unscrewing the screws (3).
36 kV circuit-breakers
– attach the tools (1) to lift and handle the circuit-breaker
(fig. 2c);
– attach the hooks (2) as illustrated in fig. 2d and lift;
– on completion of the operation, remove the tools (1).
Always take great care during handling not to stress the
insulating parts and the circuit-breaker terminals.
The apparatus must not be handled by inserting
lifting devices directly under the apparatus itself.
Should it be necessary to use this method, place
the circuit-breaker on a sturdy supporting surface
(see fig. 3).
