Interrupting
chambers
The pole is comprised of two interrupting chambers (1) -- in a ceramic envel-
ope -- equipped at each end with a HV terminal (5).
The interrupting chambers are laid out horizontally and attached, at their
base, to a common housing (6). This housing contains the mechanism used
to transfer the operating movement to the mobile contacts of both chambers.
The interrupting can also be equipped with capacitors (7) and a corona ring
(4).
Support column Consisting of two, three or four ceramic insulators, the support column allows
the circuit--breaker to be ground--insulated and it also encloses the operating
tie--rod which is attached to the interrupting chamber’s moving contacts.
The support column can also be equipped with a corona ring (13).
Housing of the
mechanism
A housing (3) -- situated at the base of the column -- contains the lever and
crank assembly and which operates the moving contact.
The SF6filling and monitoring device (8) is also situated on the housing.

Interrupting chamber
Quenching medium The quenching medium is pressurized SF6gas or -- in particular instances --
pressurized SF6+CF4gas mixture.
Interrupting principle The interrupting chamber is of thermal blasting type, using the energy from
the arc, with an auxiliary autopneumatic effect.
Diagram
421
Description The interrupting chamber has been designed in such a way as to increase the
mechanical resistance of the working part and take advantage of the low wear
rate of the contacts subjected to the arc in SF6. The working part is enclosed
in a leak tight ceramic envelope, providing insulation between the
circuit--breaker input and output.
The chamber is made up of the following elements :
Mark Component Information
(1) Envelope Can have a long creepage
distance, depending on the
pollution level.

Opening
Opening When an electrical or manual opening order is given, the energy accumulated
in the opening spring (7) is released.
The insulating tie--rod (8), directly activated by the opening spring (7),
transmits the movement to the transfer mechanism (9) inside the housing
which causes the contacts to separate simultaneously in both chambers.
