10. EXPLOITATION

10.1. Operating mechanism operation

The cubicles are shipped with switch disconnector in the open position and earth switch in closed position. All maneuvers are made without great efforts. The motorization is not operational if the maneuver lever is placed.

The mechanism is operated using an operating lever backstop, which function is to prevent that it goes directly to the switch open position after making the closing maneuver.

10.2. Earth Switch opening operation (CI1 and CI2)

 This maneuver is possible only if the earthing switch is closed.  Insert the lever into the slot of the earthing switch maneuver.  Rotate the lever counter-clockwise to the "open" position.

This action will jam the front cable panel and release the position of the open switch.

Page 24

NORMAFIX

10.3. Earth Switch closing operation (CI1 and CI2)

 This maneuver is only possible if the switch is in open position  Insert the lever into the slot of the earthing switch maneuver.  Check that the cables do not have voltage (indicator of the presence of voltage)  Close the earthing switch, moving the lever to the final position, steering it

clockwise

This maneuver:

 Closes the Earth switch;  Unlocks the cable access front panel;  Interlocks the Switch in the opened position (it cannot be closed).

10.4. Switch closing operation (CI1 or CS1)

 This maneuver is possible only if the earthing switch is in the "open" position  Insert the lever into the slot of the maneuver switch.  Operate the lever clockwise until the final position - the switch closes abruptly.  The command of the earthing switch is stuck in the "open" position.

Page 25

NORMAFIX

10.5. Switch opening operation (CI1 or CS1)

 This maneuver is only possible if the switch is in the closed position;  Insert the lever into the slot of the Switch maneuver;  Operate the lever counter clockwise to the “open” position – the switch opens up

shaply;

 The earth switch mechanism is then cleared and can be closed.

10.6. Switch closing operation and recharge for opening (CI2 - transformer protection function)

 This maneuver possible only if the earth switch is in the open position;  Insert the lever into the slot fo the Switch maneuver;  Operate the lever clockwise until the final position;  The Switch closes and the lever remains captive.

Attention, essential maneuver following the closure of the ISF:

Operate imperatively the handle, clockwise, in order to recharge the spring. After completing this action the handle may be removed and the Switch is now ready to be opened.

Page 26

NORMAFIX

10.7. Switch opening operation (CI2 - transformer protection function)

The opening operation can be made:

 Manually (shutter release button in the mechanism)  By a coil opening (optional)  By fuses (fuses mechanical action)

10.8. Closing and opening operations (Vacuum Circuit Breaker, CDV mechanism)

 Use the lever to load the springs (execute vertical movements)  Close the circuit breaker by pressing the close button  The circuit breaker will be ready to make an opening maneuver (by pressing the

release button feeded by the release coil)

 If you want to make a new maneuver, it is necessary to recharge the springs again,

even if the circuit breaker is not open. If the circuit breaker has a powered mechanism, it will charge the springs automatically when necessary.

Page 27

NORMAFIX

10.9. Closing and opening operations (SF6 Circuit Breaker, CLR mechanism)

 Use the lever to load the springs (operate clockwise circular movements).  Close the circuit breaker by turning the maneuver button in a counter-clockwise

direction.

 The circuit breaker will be ready to make an opening maneuver (turning the

maneuver button clockwise or by discharging the opening coil).

 If you want to make a new maneuver, it is necessary to recharge the springs again,

even if the circuit breaker is not open. If the circuit breaker has a powered mechanism, it will charge the springs automatically when necessary.

11. MAINTENANCE

NORMAFIX is a maintenance-free product.

However, when the switchgear is inoperative for a long time or if it is under severe environmental conditions (dust, humidity, salty etc), it is advisable to perform the following operations whenever there is a duty break:

 Visual inspection to confirm the good condition of the material;  Wipe the dust or dirt that may arise in insulators parts (insulators, switches,

transformers, etc.) with a dry cloth. Never use solvents;

 Verify the correct operation of the mechanisms and interlocks;  Verify the correct placement of the cable connectors;  Check the tightness of all connections;  Apply a very light coat of neutral industrial vaseline (Mobil Special with MoS2) in

the male contacts of earthing switch and the electrical contacts in air, having removed the old grease with the help of a cloth impregnated with oil or other non-

chlorinated solvent.
