Figure 1.4: Tank

1.1. CUBICLE ELEMENTS The cubicle is made up of a series of independent compartments:

Figure 1.1: Main components of CGMCOSMOS modular cubicles

Figure 1.2: Main components of CGMCOSMOS compact cubicles

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 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.

[2] Applicable to CGMCOSMOS system cubicles, except the disconnector of the CGMCOSMOS-V cubicle with RA(M)V driving mechanism.

Driving Mechanism Compartment: This is the compartment in which the switch-disconnector 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 As a special option, a phase-segregation box can be housed inside the base. 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.

1.1.1. 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:

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.

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.

[5] See section 5.1. ekorSPC - Voltage Presence and Phase Balance Checking.

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 short-circuit 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). 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)

Figure 2.2: Lifting a CGMCOSMOS cubicle with slings

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]

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).

[6] Position the rear of the cubicle facing the driver, to avoid damaging the front.

Figure 2.1: Lifting a CGMCOSMOS cubicle using a forklift truck

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.

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.

3. STORAGE 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.

• Maximum height above sea level 2000 m • Store in non-corrosive environments

Any other conditions must be notified beforehand, since the equipment must be factory-adjusted to the atmospheric pressure. Otherwise, the needle may indicate an incorrect value (red scale), even though the value of the equipment internal pressure is correct. Otherwise, the manometer needle may indicate an incorrect value, even if the equipment internal pressure is correct.

NOTE In addition, cubicles are available up to class:

«– 30 ºC interior (– 40 ºC storage)».

4. INSTALLATION 4.1. UNPACKING THE EQUIPMENT CGMCOSMOS system cubicles come wrapped in protective plastic.

On receiving the equipment, check that the goods supplied correspond to the order and associated documentation.

The process for unpacking the equipment is as follows:

1. Using a blade, cutter or similar tool, cut the cellophane wrapped around the cubicle[7].

2. Remove the cellophane.

3. Detach the white polystyrene corner pieces.

4. Unscrew the fixings between the base and the pallet.

5. Remove the pallet, handling the cubicle as indicated in section 2.1.

6. Unpack the accessory box located at the rear bottom or at top of the cubicle.

7. Remove the self-adhesive protective plastic from the cable compartment cover. Remove the cover.

8. Dispose of any waste in an environmentally-friendly manner.

It is advisable to make a visual inspection of the equipment to check whether it has suffered any damage in transit. If so, contact Ormazabal’s Technical - Commercial Department immediately.

[7] It is advisable to cut the cellophane at the rear of the cubicle or at the corner to avoid scratching the surface.

CAUTION The self-adhesive plastic must be removed from the cable compartment cover so that the equipment enclosure’s earth connection may have the proper electrical continuity.

4.2. CIVIL ENGINEERING WORKS The minimum distances to the walls and roof, and from the trench for the MV cables are as follows:

Minimum Distances [mm] Side wall (a) 100 Ceiling (b) 500

Front clearance (c) 500(*) Rear wall (d) > 100(**)

(*) The Spanish HV regulation (MIE-RAT 14) requires a minimum operating aisle space of 1000 mm (**) Except for CGMCOSMOS-V (> 50 mm) and CGMCOSMOS-M (0 mm).

The space required to extend the assembly with an additional cubicle is 150 mm plus the width of the new cubicle[8].

[8] Should a query arise, contact Ormazabal's Technical - Commercial department.

NOTE The above-mentioned measurements have been obtained in accordance with the internal arc tests, which have been carried out in a compartment 2300 mm high, for gas-insulated modules, according to annex A of standard IEC 62271-200.

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.

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.

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.

• 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:

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.

5. RECOMMENDED SEQUENCE OF OPERATIONS

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

Comparison of balanced phases Comparison of unbalanced phases

There is NO indication on the comparator. YES, there is indication on the comparator.

[14] Optionally, other comparison devices which comply with the IEC 61958 standard may be used. [15] See section 1.1.1. Voltage Indication of this General Instructions document.

5.6.9. 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. 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.

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.

NOTE No polarity is defined for 230 Vac voltage, so either the phase or neutral conductor can be connected.

Figure 6.1: Connecting the ekorVPIS unit




20.12.2012

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)
