Each of the three poles of a fluidblast circuit interrupter comprises a
fixed contact carried by the operating cylinder of a puffer
mechanism, whose piston is connected to the movable contact
operating means by two rods extending through the cylinder and
fixed contact structure, the piston during an opening operation,
commencing its movement before the movable contact. Figs. 3A and
3B show a weatherproof porcelain tube housing a cylinder 48 carrying
a contact plate 62 and fixed contact 32, the latter being enclosed in
an orifice 43 communicating with the cylinder 48 through holes in the
plate 62, Fig. 4 (not shown). The movable contact 33 bears, through
springs 34, 35, against a sleeve 37 connected to a verticallymovable
operating rod 22 and carrying another sleeve 39 having a projection
39a engageable with a flange 40 on the contact 33, which is guided
by a sleeve 54 and is connected through contact fingers 50 to a
terminal plate 53 having a contact 5. The sleeve 39 has portions 45
connected to piston-rods 46 secured to a piston 47, the pressure on
whose upper face is stabilized, during contact opening and closing,
by apertures 49 in the cylinder 48. To open, rod 22 is moved
downwards, thus lowering the piston 47 to build up pressure in the
cylinder 48 until members 39a, 40 engage, whereupon contacts 32, 33
separate and the arc between them is extinguished by a fluid blast
from the cylinder 48. The springs 34, 35 faciliate reclosure and provide
the contact pressure. Porcelain housings 24, 25 are mounted on a
housing 11 containing the operating mechanism for the rod 22, and
all three poles of the interrupter are carried on a movable truck 2
which supports a mechanism compartment 13 operating all the pole
mechanisms simultaneously, closing being by solenoid action, thus
tensioning opening springs which are retained latched until tripping.
The interrupter may be used with metal-clad switchgear, its external
contacts 4, 5 co-operating with contacts 7 on a panel 10. Alternative
orifice structures are described, Figs. 8 and 9 (not shown), and the fluid
used may be sulphur hexafluoride, selenium hexafluoride, or one or
both of these mixed with air, carbon dioxide, argon, helium or
nitrogen. Alternatively, air alone may be used or a liquid such as oil.
The current-carrying capacity may be increased by connecting the
interrupter contacts in parallel with main contacts which do not break
the arc.

A vertical mounting plate (47) supports on one side three split-shell
cylindrical chambers (1,2,3) in plastic material with conducting
external surface. Aligned horizontally and communicating internally
via sealed band-joints (8), the shells are filled with pressurised e.g. SF6
gas. Shells are vertically divided, the halves (1',2',3') next the mounting
plate containing isolating switches capable of connecting feeder
cable terminations (15,32), traversing the plate, with busbars in the
other half-shells (1'',2'',3''), or with earth. One shell (3) is backed by an
insulated case (51) containing single-pole vacuum or SF6 circuit-
breakers - opt., a fuse-cabinet - controlling local MV equipment, e.g.
a transformer, with associated earthing switch (63). An outer cabinet
(41,81,82,83), of metal plates cut, folded and riveted, supports the
equipment and its LV ancillary gear.

19950622
HV substation primary, e.g. copper, phase conductors (1) are each
centrally supported within an e.g. aluminium earthed casing (2) filled
with SF6 gas (3). Oscillatory overvoltages produced e.g. by switching
are attenuated by a carbon-based layer (5B) applied by deposition,
or as a prefabricated sleeve inserted during assembly, over a 3 to 10m
length of the conductor. The layer's thickness is designed to produce
a radial resistance equal to the circuit characteristic impedance, the
attenuator being completed by series capacitance established
between the surfaces of the layer and the casing. Opt., layers are
applied both to the conductor (5B) and the inner casing surface (5A),
or to the latter only. Opt., also, desired capacitance values are
obtained using a different dielectric (6) from SF6.

The switching system, preferably suitable for distributing electric
energies of medium-high voltage, includes a metal housing which is
filled with insulating gas and in which at least one circuit breaker, one
isolating switch, one earthing or grounding system and one busbar are
arranged. In this arrangement, the contact arrangement of the circuit
breaker is located in a housing which is accessible from the outside
without intervention in a busbar housing which contains the busbar.
This system saves parts and has a small space requirement while its
components subject to the most wear are easy to maintain. This is
achieved by the fact that the contact arrangement of the isolating
switch is provided in the busbar housing and that the housing of the
circuit breaker is provided with a housing part of insulating material
which penetrates the wall of the busbar housing as a gas-tight current
lead-through. In a system of three-phase design, the volume of the
busbar housing is additionally reduced by the fact that the three
phase conductors of the busbar are helically wound around a
common axis.

vessel (14, 16) which has such an expansion capacity and is otherwise
dimensioned and designed such that, on reaching a defined limiting
gas overpressure value in the interior of the switch housing, it can
absorb an element of at least ten per cent of the gas volume in the
switch housing. The expansion vessel can be constructed as a metal
bellows or plastic bellows or as a balloon (preferably trapped inside a
cage) consisting of rubber-elastic material or, finally, it can be formed
from a piston/cylinder arrangement. In consequence, in particular,
relief of the stress on the sealing points of the encapsulated switch

The switching installation comprises a metal housing (1) which is filled
with insulating gas and in which at least one power circuit breaker (2),
an interrupter circuit breaker, an earth and a busbar (25) are
arranged. In this case, the contact arrangement of the power circuit
breaker (2) is located in a housing (7) which is accessible from the
exterior without having to gain access into a busbar housing (13)
which surrounds the busbar (25). This installation is intended to be
distinguished by a saving of parts and small space requirements with a
high level of ease of servicing of its components which are most highly
stressed. This is achieved in that the contact arrangement of the
interrupter circuit breaker is provided in the busbar housing (13) and in
that the housing of the power circuit breaker (2) has a housing part
(12) which consists of insulating material and passes through the wall
of the busbar housing (13) as a gas-tight power bushing. In the case of
an installation of three-phase construction, the volume of the busbar
housing (13) is additionally further reduced in that the three phase
conductors of the busbar (25) are wound around a common axis in
the form of a helix. Such a switching installation is preferably suitable
for distributing medium voltage electrical power.

of a partition wall between the busbar compartment and the rest of
the cell. Additional equipment for individual cells can comprise an
earthing switch 74, protective line fuses 72 for the outgoing equipment
and a variety of alternative cable entry and termination means. The
puffer-type circuit-breaker, Fig. 10, has a monobloc-type moulded
housing 118 with a sealed rear cover 114, and with an internal
mounting member 142 for the movable contact rods 132 there is
formed a rear compartment 111 in which a common drive shaft 124,
individual insulating cranks 126 and link couplings 128, 130 for each
pole are situated, the contact rods being connected to busbar side
terminals 40, 42, 44 of the circuit-breaker by flexible braids 154. In a
front compartment 116 the end face 140 of the housing supports
incoming terminals 34, 36, 38 and fixed contacts 136 whilst the puffer
device comprising a piston, nozzle and aperture assembly 146, 148,
150 is secured by the movable contact 134 to the contact rod 132
and cooperates with an open-ended cylinder 144 integral with the
member 142. The rear compartment 111 also contains an earth bar
156 more closely spaced to the live link coupling 130 than the
separated distance of the two contacts 134, 136 so that an excessive
voltage rise on the busbar side will flashover to earth rather than

A metal-encapsulated medium-voltage switching installation (2) has a
switching element (32) which operates as an interrupter switch, is
supported such that it can move in a pivoting manner and can be
engaged with at least one mating contact (38, 40). In this case, the
mating contacts (38, 40) each have a curved track (48) so that the
moving switching element (32) executes a radial forced movement
when it moves into the contact limit position. This forced movement is
transmitted onto a load or power switch, especially in the form of a
vacuum switch (12), so that the vacuum switch (12) is closed in the
two contact limit positions of the switching element (32) but in
contrast is open in all the intermediate positions between the mating
contacts (38, 40) of the vacuum switch (12). In this case, the closing
and opening of the vacuum switch takes place after and respectively
before the contact-making and interruption respectively of the
interrupter switch so that reliable, load-free switching of the interrupter
switch is ensured.

The invention relates to a method for extinguishing an interference arc
in a mid- and high-tension switchgear assembly, with which,
according to the preamble of patent claims 1 and 3, at least one
short circuit element is connected between the phases of a three-
phase alternating current distributor. In order to extinguish the
interference arc more reliably, the invention proposes that the
interference is detected by sensors and that the short circuit switching
element is fired by means of an explosive charge that impacts directly
on the short circuit switching element on a conical contact structure
complementary to the short circuit element connected to the three-
phase power lines in such a way that, with the help of the
complementary contours of the short circuit switching element and
the three-phase power lines, self-locking persistence is achieved in the
short circuit condition without having to apply a retaining force.

comprising it. This involves the application of a vacuum breaker which
is interconnected in such a way with the other equipment, that the
main power flow of the loop is channeled only through this vacuum
breaker. All the other switchgear need to break only the distribution
transformer load current with the possible consequence to enable the
elimination of the SF6 and the use of mineral oil, esters or solid
insulation instead. Additionally, the improvement of the reliability of
the cable network is accomplished by introducing automatic
sectionalizing points and the elimination of the HRC fuses by having
the vacuum breaker protect the distribution transformed. In case of

The invention concerns a circuit breaker comprising inside an
interrupter chamber, a hollow arcing contact (3B) and an arcing
contact in the form of a rod (5B) inserted in said hollow contact (3B)
along an axial direction (A) when the circuit breaker is closed, and a
blower tube (9) which is coaxial and integral with the hollow arcing
(3B) and has a tube throat (9A) traversed by the rod-shaped arcing
contact (5B), the hollow arcing contact (3B) and the blower tube (9)
and the rod-shaped arcing contact (5B) being displaced along the
axial direction (A) in opposite directions when the circuit breaker is
opened. The invention is characterised in that the blower tube (9) is
guided in translation along the rod-shaped arcing contact (5B) when
the two arcing contacts (3B, 5B) move in opposite directions, thereby
reducing the risk of contact or friction of the tube throat (9A) on the
rod-shaped contact (5B), thus increasing the circuit breaker
interrupting capacity.

A method of monitoring the quality of filler gases, in particular of sulfur
hexafluoride (SF6), in a gas-filled installation, in particular in gas-
insulated switch units, such as high and medium voltage switches, a
solution is provided which enables a continuous monitoring of the
quality of filler gases in the gas-filled installation, which simultaneously
enables to possibly determine the location of a fault and a type of the
fault in such an installation. This is achieved by virtue of the fact that
the filler gas of the installation, at least for the time of the analysis, is in
a condition of a constant gas exchange with an ion-mobility
spectrometer, in which the filler gas is ionized, and the ions are finally
analyzed in the drift channel of the ion-mobility spectrometer.

19880616
Encapsulated switch disconnector arrangements are increasingly
used in medium-voltage switching installations. The reason for this is
that they occupy a smaller amount of space than large-volume, air-
insulated switching cells. The object now exists of accommodating all
the important parts in a single, encapsulated housing, of further
reducing the number of parts and of reducing the cost for the arc
extinguishing device, with the same performance capability as the
previous devices. The invention specifies an encapsulated switch
disconnector arrangement in the case of which the moving contact
piece is constructed as a double disconnecting blade (isolating
blade) 1 and can be switched into three positions, and the
extinguishing device consists of arc splitters 4 which are arranged in
overlapping layers parallel to a busbar 12 (which is laid in the interior
of the housing 9) in such a manner that the arc which is produced
during the switching-off movement of the double isolating blade is
bounded by a cohesive cooling surface. Such an encapsulated
switch disconnector arrangement can be used in a plurality of
configurations and for the R, Y and B phases in an encapsulated
housing 9 which is filled with sulphurhexafluoride (SF6), it preferably
being possible to use such a switching installation in mains power
supply distribution stations.

Encapsulated medium voltage switchgears, filled with insulating gas,
are being used increasingly because of their small dimensions and a
minimal maintenance cost. There is now an endeavour to operate
such switchgears conspicuously. Originating from the lever drives for
relatively small and medium-size switchgears up to control rooms for
centralised remote operation of large switchgears, the task exists of
producing a simple remote control for a medium voltage switchgear.
2.2 The invention indicates a solution in which a frontplate 4 of the
drive housing 1 is provided with a number of switch cylinders 5
corresponding to the number of switching apparatuses, the piston
rods 21 of which switch cylinders 5 are in each case connected in a
force- fitting manner via a coupling element 8, 9 to one of the
switching shafts 2, and a hydraulic set 12-16, known per se, is inserted
in the base 25 of the switch housing 21, which hydraulic set 12-16 is
connected via pressure lines 7 to the switch cylinders 5. 2.3 Such a
medium voltage switchgear can be used in a versatile manner, e.g.
with ring-cable switches, with cable switches and a transformer
switch, a high-voltage, high rupture capacity fuse being inserted in
the transformer outlet.

arms which are spaced angularly apart from one another, the arms
extending radially from the shaft. For each switching blade on the
shaft, there are at least three terminal contacts 14, 16, 18 spaced
angularly apart from one another and lying on a circle 22 centred on
the shaft axis. Rotation of the shaft results in a simultaneous double
make or double break between the arms and the relevant terminal
contacts. A ring main unit having a number of such switching
arrangements is also described, with three parallel shafts each

An electrical encapsulated medium-voltage switching installation has
a medium-voltage power circuit breaker (32), especially a vacuum
circuit breaker, or SF6 circuit breaker, which is assembled from
individual circuit breaker poles which are connected to busbars (12)
for supplying current via in each case one interrupter circuit breaker
(20). An earth circuit breaker (64) is provided between the power
circuit breaker (32) and the encapsulation (28). In order to prevent
arcs occurring in every case an intermediate contact (80) passing
through the encapsulation (10, 28) is provided on said encapsulation
(10, 28), by means of which intermediate contact (80) the moving
contact (84; 18) of both the earth circuit breaker and of the
interrupter circuit breaker can be connected. The intermediate
contact (80) is not connected to earth potential when the earth
circuit breaker is switched off, so that an internal earth is created by
interaction between the moving contact (18) of the interrupter circuit
breaker (20) and the intermediate contact, and an external earth is
created by interaction of the moving contact (64) of the earth circuit
breaker with the intermediate contact (80). The encapsulation is
preferably produced from insulating material, and the filling of the
encapsulation consists of SF6 insulating gas.
