Extinguisher
environment
The extinguisher environment is SF6gas under pressure or, exceptionally,
amixofSF
6gas +CF4under pressure.
Principle of breaking The breaking chamber is thermal blowing by arc energy type, with
auxiliary auto--pneumatic effect.
Description The breaking chamber was designed to increase the mechanical and
electrical endurance of the active part and take advantage of the benefits
of the low wear of the contacts subjected to the arc in the SF6. The active
part is enclosed in a sealed ceramic envelope, for insulation between the
input and the output of the circuit breaker.

Opening
Description On electrical or manual order to open, the energy accumulated in the
opening spring (10), located in the operating mechanism, is freed.
The insulating operating rod (8), actuated by the opening spring (10),
transmits the movement to the mobile parts (6) and (7), which ensures
separation of the contacts.

Operation The following table gives the opening phases:
Phase Description
Start
of opening
When the mobile contact (4) leaves the main contacts (3),
the current is switched on the arc contacts (10). The
volume compression (Vp) creates an initial increase in
pressure.
Vp

Thermal
effect
On separation of the contacts (10), the arc appears and its
energy causes a pressure increase in the volume of
thermal expansion (Vt) colsed by the contact rod (11) and
the insulating nozzle (12).

and
assistance
on opening.
When the rod (11) leaves the nozzle (12), the thermal
overpressure in the volume (Vt) is freed, which causes
energetic blowing, just before the zero--crossing of the
current, ensuring the final extinction of the arc. The
overpressure of the volume (VP) escapes via the valve
(13).

Opening, continued
Operation, continued The following table continues the opening phases:
Phase Description
”OPEN”
position
The arc goes off.
The molecules of SF6dissociated by the arc are
instantaneously reconstituted.
The residual gases from the break are adsorbed by the
molecular sieve, located at the base of the pole. Some
powdered products are deposited in the form of dust,
without impact on the circuit breaker.
Particular case
of small currents
In the case of weak currents(eg : operating unloaded lines, transformers,
or capacity banks), the arc’s thermal energy is too weak to cause enough
overpressure.
As a result, to obtain the arc blowing, the traditional auto--pneumatic effect
is mainly used; it develops in the volume (Vp), and blows in the volume(Vt)
until arc contact.

Closing
Description On electrical or manual order to close, the energy accumulated in the
opening spring (11), located in the operating mechanism, is freed. This
energy is transmitted to the operating shaft (16) of the pole, and ensures
closing.
The liberation of the energy stored in the closing spring (11) causes the
displacement of the mobile components and therefore the closing of the
breaking chamber, as well as resetting the opening spring (10).
