b breaking principle
The exceptional qualities of SF6 gas are used to extinguish the electrical arc.
To increase cooling of the arc, a rotative movement is created between the arc and
the gas. The arc appears when the fixed and moving contacts separate.
The combination of the current and a magnetic field created by a permanent magnet
provokes arc rotation around the fixed contact, resulting in arc extension and cooling
unit it is extinguished at current zero.
The distance between the fixed and moving contacts is then sufficient to withstand
the recovery voltage.
This system is both simple and sure and also provides improved electrical endurance
due to very low wear on contacts.

SF6, the switchgear manufacturer’s gas
SM6-36 switch-disconnectors and earthing switches use sulphur hexafluoride gas
(SF6) for insulation and breaking. The active parts are placed in an insulating
enclosure in accordance with the definition of IEC 56/Appendix EE (1987 edition) for
sealed pressure systems.
SM6-36 devices offer remarkable characteristics:
b long service life
b maintenance-free active parts
b high electrical endurance
b very low over-voltage level
b operating safety.

SF1 circuit breaker
The SF1 circuit breaker is made up of three separate pole mounted on a structure
supporting the operating mechanism. Each pole-unit houses all the active elements
in an insulating enclosure filled with gas to a relative pressure of 2 max bar.
This system offers maximum operating reliability:
b gas tightness
The enclosure filled with SF6 gas satisfies “sealed pressure system” requirements
and seal tightness is always checked in the factory.
b operating safety
As for switch-units, accidental over-pressures are eliminated by the opening of the
safety membrane.
b breaking principle
The circuit breaker is based on the SF6 gas autocompression principle.
The inherent qualities of SF6 and the soft break resulting from this technique reduce
switching over-voltages.
SF1 circuit breaker.
b precompression
When the contacts begin to open, the piston slightly compresses the SF6 gas in the
pressure chamber.
b arcing period
The arc then forms between the arcing contacts and the piston continues its
downward movement. A small quantity of gas, directed by the insulating nozzle, is
injected into the arc.
The cooling of the arc is thus achieved through forced convection for the interruption
of low currents, however, during the interruption of high currents, thermal expansion
is responsible for the transfer of the hot gases toward the cold parts of the pole unit.
Toward current zero, the distance between the two arcing contacts is sufficient for
final interruption of the current due to the dielectric properties of the SF6 gas.

Reliable operating mechanism
Switchgear status indicator
Fitted directly to the mobile equipment’s shaft, these give a definite indication of the
switchgear’s position (appendix A of standard IEC 60129).
Operating lever
This is designed with an anti-reflex device that stops any attempt to re-open the
device immediately after closing the switch or the earthing disconnector.
Locking device
Between one and three padlocks enable the following to be locked:
b access to the switching shaft of the switch or the circuit breaker
b access to the switching shaft of the earthing disconnector
b operating of the opening release push-button.
Simple and effortless switching
Mechanical and electrical controls are side by side on the front fascia, on a panel
including the schematic diagram indicating the device’s status (closed, open, earthed).
Closed:
the mobile equipment is operated via a quick acting mechanism, independent of the
operator. No energy is stored in the switch, apart from when switching operations are
taking place.
For combined switch fuses, the opening mechanism is armed at the same time as
the contacts are closed.
Opening:
the switch is opened using the same quick acting mechanism, operated in the
opposite direction.
For circuit breakers and the combined switch fuses, opening is controlled by:
b a push-button
b a fault.
Earthing:
a specific control shaft enables the opening or closing of the earthing contacts.
Access to this shaft is blocked by a cover that can be slid back if the switch is open
but which remains locked in place if it is closed.
Voltage presence indicator
This device has integrated VPIS (Voltage Presence Indicating System) type lights, in
conformity with IEC standard 61958, enabling the presence (or absence) of voltage
to be checked on the cables.

Safety of people
By internal arc protection (optional)
Standard IEC 60298 appendix AA indicates
a method for testing switchgear in metal
enclosures under internal arcing conditions.
The aim of this test is to show that an
operator present in front of a switchboard
would be protected against the effects of an
internal fault.
To enhance the safety of people, it is desirable to provide as high a degree of
protection as possible by evacuating the effects of internal arcing using:
b evacuation systems which direct gases towards the top or the bottom of the
switchboard enabling over pressure to be limited in the case of an internal fault in the
compartments
b channelling and evacuating hot gases towards an external area, which is not
hazardous for the operator
b materials which are non-inflammable for the cubicle
b reinforced panels.

In its internal arc version, the SM6-36 range has successfully passed all of the type
testing relative to standard IEC 60298 (6 acceptance criteria).
The materials used meet the constraints for which the SM6-36 is designed.
The thermal and mechanical forces that an internal arc can produce are perfectly
absorbed by the enclosure.

things, on the following criteria:
b service voltage
b transformer rating
b fuse technology (manufacturer).
Different types of fuses with medium loaded striker may be installed.
Fusarc CF fuses as per DIN dimensions 43-625.
Example:
For the protection of a 400 kVA transformer at 33 kV, select Fusarc CF fuses rated

(1) Please consult us for overloads and operation over 40 °C.
(2) This selection table has been prepared according to the technical characteristics of France
Transfo.
The characteristics of transformers and fuses may change according to manufactures and
standards.
Access to fuses
Access via the front with the front panel removed. Fuses may be removed without
tools by simply pulling them forward. The field deflector pivots and automatically
returns to its position.
Replacement of fuses
When fault clearance results in one or two blown fuses, it is still common practice
to replace only the blown fuses.
However, though the remaining fuse(s) may apparently be in good condition, their
operating characteristics are generally reduced due to the short-circuit. If non-blown
fuses remain in service, they may blow even at very low over-current values.
In systems where continuity of service is of importance, it is recommended to
replace all three fuses, in compliance with IEC recommendation 282.1.

Fixing of units
With each other
The units are simply bolted together to form the MV switchboard (bolts supplied).
Busbar connections are made using a torque wrench set to 28 mN.
On the floor
b for switchboards comprising up to three units, the four corners of the switchboard
must be secured to the floor using:
v bolts (not supplied) screwed into nuts set into the floor using a sealing pistol
v screw rods grouted into the floor
b for switchboards comprising more than three units, the number and position of
fixing points depends on local criteria (earthquake withstand capacities, etc.)
b position of fixing holes depends on the width of units.
