CAUTION!
When MV equipment is operating, certain components are live, other parts may be in movement and some may reach high
temperatures. Therefore, the use of this equipment poses electrical, mechanical and thermal risks.
In order to ensure an acceptable level of protection for people and property, and in compliance with applicable environmental
recommendations, Ormazabal designs and manufactures its products according to the principle of integrated safety, based on
the following criteria:
•
Elimination of hazards wherever possible.
•
Where elimination of hazards is neither technically nor economically feasible, appropriate protection functions are
incorporated in the equipment.
•
Communication about remaining risks to facilitate the design of operating procedures which prevent such risks,
training for the personnel in charge of the equipment, and the use of suitable personal protection equipment.
•
Use of recyclable materials and establishment of procedures for the disposal of equipment and components so
that once the end of their service lives is reached, they are duly processed in accordance, as far as possible, with
the environmental restrictions established by the competent authorities.
Consequently, the equipment to which the present manual refers complies with the requirements of section 11.2 of the
forthcoming IEC standard 62271-1. It must therefore only be operated by appropriately qualified and supervised personnel, in

Gas tank: Sealed compartment which houses the busbar and the switching
and breaking elements, where the insulating medium
is SF6 gas.
The tank has a membrane to allow gases to escape
in the event of an internal arc.
Each tank has a manometer for checking the gas
pressure, which can easily be seen from outside the
Figure 1.3: manometer
cubicle. The manometer scale is divided into different
colours: red, grey and green. For safe operation, the needle must be in the
green zone of the corresponding temperature band.

Switch - Disconnector and Earthing Switch: This component has three positions: closed,
open and earthing.
The operation is carried out using the actuating lever on 2 different actuation zones: one for
the switch (switching between the closed and open positions); and another for the earthing
switch (which switches between the open and earthing positions) on the feeder cables, and
in the case of fuse protection cubicles, on the six fuse-holder clamps.
These elements are operated independently[2], i.e., their actuation speed does not depend on
the speed of the manual operation.
Vacuum Circuit Breaker: The CGMCOSMOS-V cubicle's circuit breaker uses vacuum
switching technology.
The circuit breaker is actuated by means of the push-button on the front of the cubicle. For
manual operation, springs must be charged with the corresponding lever.
The CGMCOSMOS-V circuit breaker cubicle has two options for ensuring the isolating
distance
a) RA(M)V driving mechanism. The circuit breaker comes standard equipped with a
disconnector and an earthing switch.
b) A(M)V, AV (3G) or RAV (3G) driving mechanism. The circuit breaker comes
standard equipped with a switch-disconnector and an earthing switch.
In both cases, this element is operated using a specific lever depending on the type of driving
mechanism.
The motorised CGMCOSMOS-V circuit breaker cubicles may optionally be equipped with an
electromechanical safety device called an undervoltage coil. Its function is to ensure that the
cubicle circuit breaker opens in the event of an unexpected drop of more than 30% in the
auxiliary voltage.
CAUTION
When the CGMCOSMOS-V circuit breaker cubicles with A(M)V or RA(M)V driving
mechanism have an undervoltage coil, a possible lack of auxiliary voltage in the coil
could cause the cubicle to block if it is in earthing position.
For these occasions, the undervoltage coil has a manual blocking mechanism that
retains the trip rod while the manual mechanism remains actuated and the coil has no
voltage.
For more information on how to carry out the manual blocking of the undervoltage coil
or how to act in the event of an accidental blocking of the cubicle, see the Spares and
Accessories Instructions document RA-232.

Driving Mechanism Compartment: This is the compartment in which the switchdisconnector or the circuit breaker is actuated, depending on the type of cubicle. The mimic
diagram for the MV main circuit is displayed on the cover of this compartment.
The mimic diagram includes all the position indicators for the actuators.
The driving mechanisms can be replaced (due to improved
characteristics) in any of the three switch-disconnector
positions. These positions can be blocked on the B, BM and
BR driving mechanisms by means of a padlockable coupling
device, whether or not the cubicle is operating.

Base: Made up of the cable compartment and the gas relief compartment:
Cable compartment: This is located in the lower front section of
the cubicle and has a cover interlocked with the earthing switch,
thus allowing front access to the Medium Voltage cables.
It is designed to contain up to:
•
Optionally, 2 shielded screw-in terminals per phase or one
terminal plus a surge arrester with space for the
corresponding incoming power cables.
•
Cable ties for the power cables.
•
Earthing bars
Figure 1.21: Cable Compartment
As a special option, a phase-segregation box can be housed inside the base.
3b
Gas relief compartment: This is located in the lower rear section of the cubicle. In the event
of an internal arc, the gases produced are deflected downwards and to the rear, and in no
way affecting any persons, cables, or the rest of the Transformer Substation switchgear.

Voltage presence indicator
Ormazabal offers two options for the voltage presence indicator:
• The ekorVPIS unit for indicating the presence of voltage has been designed in
accordance with the IEC 61958 standard. Therefore, the “presence of voltage” indication
appears when the phase-earth voltage is greater or equal to 45% of the rated voltage and
does not appear when the phase-earth voltage is less than 10% of the rated voltage.
• The ekorIVDS unit for detecting the presence of voltage has been designed in
accordance with the IEC 61243-5 standard. Therefore, the “presence of voltage” is
detected when the phase-earth voltage is between 45% and 120% of the rated voltage
and does not appear when the phase-earth voltage is less than 10% of the rated voltage.
Both units provide a clear visual indication to the user, and do not require an auxiliary power
supply to operate.
For each of the three phases, the presence of voltage is indicated by intermittent flashing of
the indicators.
The voltage detection unit has the following indicators:
1
2
4
2
L 1, L2 L3
Display each of the indicator phases
The numbering corresponds to the order of the
phases, from left to right, seen from the front of
the cubicle. Each phase has a test point for
checking the phase balance between cubicles.
Voltage presence indicator
A flashing light indicates the presence of voltage
in that phase.

Phase test points
Each phase has a test point for checking the
phase balance between cubicles.
4
Earth test point
This is only used for comparing the phases.
Figure 1.22: Unit to indicate the
presence of voltage
The purpose of the test points for the three phases and earth is to make it easier to check the
phase balance[5] between cubicles. Ormazabal's specific phase comparator ekorSPC can be
used to do this.
CAUTION
If the indicators on the ekorVPIS unit do not light up, other methods should be used to
check for the absence of voltage.

1.1.2.
ekorSAS - Acoustic Earthing Prevention Alarm Unit
The ekorSAS acoustic alarm unit is associated with the ekorVPIS voltage presence indicator
and actuation of the earthing shaft. The alarm is activated when
there is voltage in the cubicle's MV feeder and the lever is inserted
in the earthing switch shaft. A sound then indicates that a shortcircuit or zero voltage may occur in the network if the operation is
carried out.
On RAV-type CGMCOSMOS-V cubicles the alarm sounds when
there is voltage on the line and the earthing preparing operation is
performed (switch in earthing position and circuit breaker open).
Figure 1.23: ekorSAS Unit
Operation of the unit is assured within the same operating range as the ekorVPIS unit
associated with it.
NOTE
•
In the cubicles equipped with the ekorVPIS unit for the indication of the
presence of voltage, the ekorSAS unit is fitted as standard in the CGMCOSMOS
system feeder functions and can be supplied on request for the other
functions.
•
The cubicles equipped with the ekorIVDS unit for detecting the presence of
voltage are never fitted with the ekorSAS unit (option not compatible)

2. TRANSPORT
2.1. LIFTING METHODS
The cubicles must always be kept upright, directly on the ground or on a pallet depending on
the type of handling involved.
To handle assemblies of up to 4 CGMCOSMOS functional units, one of the following
methods must be used:
1.
Using a forklift truck or hand-operated pallet truck[6]
Figure 2.1: Lifting a CGMCOSMOS cubicle using
a forklift truck
2.
Raising it using slings fixed to the lifting supports on the sides of the top of the
cubicle. The angle of pull should be as vertical as possible (with an angle greater
than 60º from the horizontal).

3.
If it is not possible to use the aforementioned methods, rollers may be used
underneath the cubicles. Another option is to slid the cubicles over rods (these same
rods can be used to help get over the trench).
4.
To handle 5 functional unit assemblies (consisting of either coupled modules or
compact assemblies associated with modules), use lifting systems (slings, lifting
beam, etc,...) with a pull angle greater than 65º and less than 115º in order to
prevent possible damage to the cubicles during hoisting.
Figure 2.3: Lifting a 5 functional unit assembly CGMCOSMOS
by means of lifting beam and slings.

CAUTION
The use of lifting beams is required for cubicle assemblies with control boxes As the
sole exception, slings may be used if all the cubicles of the assembly have identical
height control boxes installed.

If it needs to be stored, the equipment must be placed on dry ground or on top of damp-proof
insulating material, still in its original packaging.
After prolonged storage, clean all the insulating parts carefully before commissioning the
equipment. The enclosure should be cleaned with a clean dry lint-free cloth.
NOTE
In addition, cubicles are available up to class:
«– 30 ºC interior (– 40 ºC storage)».
•
•
Maximum height above sea level 2000 m

4.3. FASTENING TO THE FLOOR
Before assembling the cubicles, the floor must be carefully levelled to prevent any
deformation which may make it difficult to connect the cubicles to one another.
The cubicles can be fastened to the floor in two ways:
4.3.1.
Floor fastening On a profile
If the floor of the Transformer Substation is not sufficiently uniform, it is advisable to install
the MV cubicle assembly on an auxiliary profile, to make it easier to connect them. This
profile, which can be supplied to order, must be anchored to the floor using expansion
screws.

CGMCOSMOS SYSTEM
version 09
20.12.2012
4.3.2.
Fastening to the Floor By Anchorage
If the floor of the Transformer Substation is even enough, it is advisable to install the MV
cubicle assembly directly anchored to the floor.
The sequence for anchoring the cubicles to the floor is as follows:
1.
The cubicle's switch must be in the earthing position[9].
NOTE
By default, the cubicles are supplied with the switch in earthing position.
2.
Remove the cable compartment cover, using the central handle on the cover to pull
it up and forward as indicated in the figure.
Figure 4.2: Removing the lower cover
3.
Anchor the first cubicle to the floor of the Transformer Substation using screws
through the holes made in the base for this purpose. This will prevent vibrations or
movements due to short-circuits, possible flooding of the Transformer Substation,
etc. Take the following dimensions and figures into account.

•
For cubicles measuring 1740 mm, use the four anchorage points shown in
figure 4.16.
Figure 4.15: Location of corner holes on CGMCOSMOS cubicles
•
For 1300 mm high cubicles, apart from the front anchorage points, position the
angle bars supplied with the equipment and fix them to the floor, so that once
the anchoring process is complete they are approximately in the middle of the
rear gas output. Fit one angle bar per function and two on compact cubicles.
Figure 4.16: Push from the front of the cubicle
•
Figure 4.17: Cubicle with angle bar in central position
Another possibility for 1300 mm high cubicles, in addition to the front anchoring
points, is to fasten the cubicle to the floor via the two anchorage holes on the
side.

CAUTION
Earthquake resistance
The CGMCOSMOS system has earthquake resistant equipment, as an option.
The earthquake resistance of this type of switchgear does not only depend on the
equipment construction and design, but also on the installation.
In order to anchor this type of cubicles properly, use the six points indicated in the
figure below:
91.5 mm
For further information please consult Ormazabal’s Technical - Commercial
Department.
Once properly levelled, the final installation of the MV cubicle assembly only requires
electrical and mechanical coupling between the different cubicles, and then anchorage to the
floor, which must be carried out as indicated above.

4.6. CABLE CONNECTION
The MV incoming and outgoing feeders are linked to the transformer or other cubicles via
cables. These cables and the corresponding bushings on the CGMCOSMOS system
cubicles can be connected with simple (plug-in) or reinforced (screw-in) connecting points,
either IEC type or IEEE-386 compliant.
CAUTION
Never touch live connectors, not even screened connectors. Screening does not
constitute a protection against direct contact.
When the equipment is in service and a reserve cubicle is left with voltage in the
upper busbar and without the cables in the lower bushings, insulating plugs must be
placed in the bushings (EUROMOLD type) or close the earthing switch and lock that
position with a padlock.

CAUTION
Before carrying out any operation when the cubicle is energised, we recommend
checking the SF6 gas pressure, using the manometer.
5.1. CHECKING VOLTAGE PRESENCE AND PHASE BALANCE
Ormazabal's ekorSPC[14] phase comparator should be used for checking that the MV cables
are correctly connected to the Transformer Substation feeder cubicles.
Firstly, connect the red cables of the ekorSPC unit to the corresponding phase test points on
the voltage indication units[15], and the black cable to the earth test point. This operation
should be repeated for all the phases: L1, L2 and L3

Fuse Replacement Sequence
To access the fuse holders, first remove the cable compartment cover. It is essential to
close the earthing switch.
Once the fuse holders can be accessed, follow these steps:
1. Since this is a switch-fuse combination cubicle, any of
the three fuses blowing causes the switch-disconnector
to open automatically.
2. When a fuse blows, this is indicated unequivocally by
the red indicator which appears on the front of the
driving mechanism compartment.

On CGMCOSMOS-P fused protection cubicles, when
the cable compartment access door is interlocked, the
tripping mechanism is reset directly and loaded
automatically.

5.12. INTERLOCKS
5.12.1.
Padlock Interlock
Each actuation shaft can be locked with a maximum of three standardised
padlocks, with a maximum handle diameter of 8 mm.
Figure 5.86: Locking with a Padlock on Feeder Cubicles
5.12.2.
Lock Interlock
The cubicles are designed to incorporate optional blocks of locks for the earthing switch,
whether open or closed.
Examples of Lock Interlocks (optional):
•
Lock 1: Earthing switch interlocked in Open Position. It avoids setting the switch to
the "earthing" position until the key for the low-voltage disconnector lock has been
recovered.
•
Lock 2: Earthing switch interlocked in closed position (ALWAYS INTERLOCK for
works without voltage). It prevents anyone from accidentally opening the earthing
switch by removing the earth from the cable.

6. MAINTENANCE
CAUTION
For safety reasons, maintenance operations performed directly on the driving
mechanism must be performed WITHOUT any actuating lever inserted.
The live parts of the CGMCOSMOS cubicle main circuit and switching equipment do not
require inspection or maintenance, as they are completely insulated in SF6 and therefore
unaffected by the external environment. Class E2 electrical endurance tests mean there is no
restriction on maintenance of the breaking components.
The operating mechanism for the CGMCOSMOS system switching equipment does not
require lubrication for correct operation throughout its estimated lifetime, according to the
service conditions specified in IEC 62271-1.
These mechanisms must be inspected when used under extreme conditions (dust, salt,
pollution). It is advisable to carry out at least one operation during the inspections.
Components manufactured from galvanised sheet steel have been painted to ensure their
resistance to rust. Any scratches, dents or similar on them must be repaired to prevent
corrosion.
6.1. VOLTAGE PRESENCE INDICATOR TEST
To test the ekorVPIS or ekorIVDS voltage presence indicator, connect it to a 230 Vac power
supply. To do this, disconnect the ekorVPIS or ekorIVDS unit from the cubicle, and, using 4
mm terminals, apply the voltage between the test point for the phase to be checked and the
earth test point.
NOTE
No polarity is defined for 230 Vac voltage, so either the phase or neutral conductor
can be connected.
If a flashing signal is observed, the device is working correctly. In order to properly test the
ekorVPIS or ekorIVDS, this check should be carried out for all three phases.
CAUTION
The voltage presence indication is not sufficient to ensure that the installation has
been disconnected from the electricity supply. Before accessing the cable
compartments, it is necessary to confirm that the line is connected to earth.
The ekorVPIS or ekorIVDS voltage indicator can be
replaced if required. To do so, loosen until removing
the two screws on the top right and bottom left of the
indicator using a medium size Philips screwdriver.
The ekorVPIS or ekorIVDS unit can then be
disconnected from the base without needing to power
down the line.

6.2. ACOUSTIC EARTHING PREVENTION ALARM TEST
To test that the ekorSAS acoustic alarm is working correctly, connect the ekorVPIS voltage
presence indicator to 230 Vac with 4 mm terminals, which are placed in the indicator between
the earth test point and the test point for the L1 phase. Maintain the auxiliary power for 5
minutes, after which time the lever is inserted in the earthing switch shaft in order to carry out
the operation. The alarm starts to sound and continues to sound for at least 30 seconds. It
will stop when the lever is removed.
The ekorSAS alarm can be replaced if necessary, since it is joined to the associated units
with two friction-fit PCB connectors:
•
•
One 3-pin connector, polarised for the Voltage Presence Indicator.
One 2-pin connector for the lever microswitch.
The process is as follows:
•
•
•
•
Remove the screws which hold the upper cap panel and remove it.
Remove the driving mechanism cover.
Gently press the lower fastening flanges on the ekorSAS unit to remove it.
Undo both connectors and replace the damaged unit; then connect it to the lever
microswitch (2-pin connector) and the voltage indicator (polarised 3-pin
connector).

6.3. PREVENTIVE MAINTENANCE FOR THE CGMCOSMOS-V CUBICLE
The driving mechanisms and other elements outside the gas tank may require preventive
maintenance; the frequency of this maintenance depends on the existing environmental
conditions (harsh environments, dust, extreme temperatures, etc.), and should be
established based on the installer's experience and their responsibility.
The maintenance should take place every 5 years or 2000 operating cycles, unless, based
on the conditions of use, the user, together with Ormazabal’s Technical - Commercial
Department, consider otherwise.
NOTE
Depending on the type of driving mechanism, the recommended preventive
maintenance procedure is described in the following Ormazabal operating manuals:
- CGMCOSMOS-V RA(M)V-type: MO-052
- CGMCOSMOS -V A(M)V-type: MO-073
- CGMCOSMOS -V A(M)V (3G) and RA(M)V (3G) type: MO-080

7.2. ENVIRONMENTAL INFORMATION
CGMCOSMOS cubicles are defined as a sealed, pressurised system, according to IEC
62271-1, which contains sulphur hexafluoride (SF6)[20].
SF6 is included in the Kyoto Protocol list of greenhouse gases. SF6 has a GWP (Global
Warming Potential) of 22,200 units. (TAR, IPCC 2001)
At the end of the product's life, the SF6 contained in it must be recovered for processing and
recycling, to prevent it being released into the atmosphere. Extracting and handling of SF6
must be carried out by qualified personnel, using a sealed bored system.
For the usage and handling of the SF6, the indications listed in IEC 62271-303 must be
followed.
The management and treatment of the rest of materials must be carried out in accordance
with the country’s current legislation.
