1. Description
GSec is a three-position SF6 gas-insulated switch-disconnector designed for use in medium voltage switchgear for secondary distribution.
GSec is used in line ingoing/outgoing panels, in those with circuit-breakers or in a combination with fuses. Typical
applications are supplying lines, protecting transformers and use in ring networks.
Thanks to its size, GSec can be installed in panels 375 mm in width or wider.
The contacts of the three phases can be set to the following positions:
LINE – OPEN – EARTH.
The enclosure of the GSec switch-disconnector consists of two half-shells, the top part being made of resin and the bottom part in stainless steel.
GSec apparatus is “sealed for life” in accordance with standard IEC 60694, wich means that the gas tightness is guaranteed for more than 30 years.
GSec has a wide range of “plug&play” accessories that can be easily installed and replaced from the front part of the apparatus.
The GSec series has been designed and tested in compliance with Standards IEC 60694, IEC 62271-102, IEC 62271-105 and IEC 60265-1.

Safety
– The stainless steel bottom part of GSec provides metallic segregation between the cable and busbar compartments, ensuring that the two compartments are earthed and therefore making conditions safer for the personnel.– Thanks to GSec design, it can be used to create
switchgear with PM (Metallic Partitions) classification for the segregation between the busbar and cable compartments.– Safety valve for exhausting accidental gas overpressure. It is installed in the rear part of the apparatus.
– Mechanical interlocks for the safety of the personnel.
– The door lock prevents the panel door from being opened when the GSec contacts are not in the earthed position. Vice versa, the lock prevents the switch-disconnector from setting to the open or line positions when the door is open.– The operating lever with “anti-reflex” function.
Maintenance free
– The enclosure of GSec is guaranteed “sealed for life” for more than 30 years, in accordance with IEC 60694 standards
– Up to 5000 mechanical operations without maintenance for GSec with the 1S - Single spring operating mechanism
– Up to 1000 mechanical operations without maintenance for GSec with the 2S - Double spring operating mechanismReliability
– The apparatus can house VPIS voltage indicators in
accordance with standard IEC 61958, for voltage detection on the cable side
– Mechanical signalling of the state of the apparatus connected directly to the operating shaft (Annex A of standard IEC 62271-102)
Ease of use
– Both the GSec operating mechanisms are equipped with springs so the operating speed is independent of the operator.
– The operating mechanism has two separate seats, one for line operation and one for earthing operation.Customizing
– A full range of “plug & play” accessories that can be easily installed on the front part of the operating mechanism allows the apparatus to be adapted to suit many applications.
– GSec can be used for incoming/outgoing units, in combination with fuses, circuit-breakers with lateral
operating mechanisms, current and voltage transformers.Compactness
– Thanks to the upper resin part it is possible to design small size apparatus and switchgear panel, while still ensuring a high level of insulation.
– The capacitive sockets for voltage indicator (VPIS) and the cable connections are already integrated in the apparatus bottom insulators. This allows to reduce the number of components of the the panel.

3. Specific product characteristics
a. Power part
The enclosure of the GSec switch-disconnector consists of two half-shells, the top part being made of resin and the bottom part in stainless steel.
Smaller sized apparatus can be created thanks to the top part in resin while still guaranteeing a high insulation capacity.
The stainless steel part provides metallic segregation between the cable and busbar compartments, ensuring that the cable compartment is fully earthed and therefore making conditions safer for the personnel. GSec can be used to create panels in the PM (Metallic Partitions) class because it provides metallic segregation between the busbar and cable compartments of the panel.
The power section of the GSec is filled with SF6 at 148 kPa absolute pressure. The gas is used as an interruption and insulation medium. Gas tightness is guaranteed for 30 years, in accordance with the specifications established by standard IEC 60694. GSec apparatus is called “sealed for life” for this reason.
The rear part of the switch-disconnector is equipped with a safety valve with predetermined rupture value that allows gas overpressure caused by an accidental fault to be relieved in safe conditions.
The GSec contacts can set to the following positions:- LINE: The line contacts are closed
- OPEN: the apparatus ensures that there is insulation between the cable side and busbar side
- EARTH: the contacts on the cable side are earthed. A mechanical signal visible from the front of the apparatus indicates the position of the contacts. In accordance with annex A of standard IEC 62271-102, this device is connected straight to the operating shaft.
The capacitive sockets for the voltage signalling devices (accessory available on request) are housed inside the three bottom insulators. Moreover, the cable connection can be created on the apparatus without the need for a cross-beam for the insulators. This cuts down on the number of components that need to be installed in the panel.
14
b. Operating mechanism
The GSec switch-disconnector can be equipped with two types of operating mechanisms: – 1S - Single spring – 2S - Double spring.
Both operating mechanisms have separate lever seats for the line and earthing operations and both can be equipped with a motor for loading the springs. Even when a motor is installed for loading the springs, it is always possible to operate GSec in the manual mode in case of emergency.
1S - Single spring operating mechanism
– It opens and closes the GSec line contacts. The energy required for the operation is obtained by compressing a spring with a lever, which closes (or opens) the device once dead center has been passed. The operating speed is independent of the operator.
– It opens and closes the earth contact at operating speeds independent of the operator. In the case of GSec/IB units, it also closes and opens the separate earthing switch at operating speeds independent of the operator. – Manual operation: with the operating lever

3. Specific product characteristics
2S - Double spring operating mechanism
– It opens and closes the GSec line contact using the
energy stored in two springs: the springs of the operating mechanism are loaded by means of a lever, after which the switch-disconnector is operated by pressing the closing and opening push-buttons. The springs must be reloaded after a closing and opening cycle. The operating speed is independent of the operator.

– Manual operation: using the operating lever and push-buttons
– Automatic or remote controlled operation: with a motor and opening and closing coils
– The contacts of the switch-disconnector also open even if only one fuse blows (GSec/T2F) or when the undervoltage coil trips
– The load state of the springs is signalled by an indicator on the front of the panel

d. Mechanical interlocks
GSec has been designed to ensure maximum safety for the operators. It therefore features the following interlocks:
– Interlock between the line and earthing operations obtained by means of separate lever seats
– Panel door interlock thanks to the door lock device: the cable compartment can only be accessed when the earthing switch is closed. Moreover, the earthing switch cannot be opened or the panel be put into service unless the door has been closed. The cables can still be tested with the door open by removing the front guard from the apparatus.
– Interlock for the push-buttons of the 2S - Double spring operating mechanism: these push-buttons cannot be operated when the operating lever is connected.
– Motor interlock: if the operating mechanism is a motor operator, operation of the motor is disabled when the operating lever is in the line lock.

3. Specific product characteristics
ABB CEF fuses for transformer protection Standard IEC 60282-1/DIN 43625
Three fuses (one for each phase) for transformer protection can be connected in series with the switch-disconnector.Selection of the fuses according to the voltage and power of the transformer, must be made in conformity with the data indicated in the table below.
Transformer protection and choice of fuses
When the isolators are used to control and protect
transformers, they are fitted with a particular type of current-limiting fuses which guarantee selectivity with other protection devices and can take the high transformer connection currents without deteriorating.
In this case, protection against overcurrents on the medium voltage side of the transformer is not indispensable since this task is carried out by the protection provided on the low voltage side. Protection on the medium voltage side can be entrusted just to the fuse, which must be chosen taking into account the no-load connection current since this can be the same or 10 times more that the rated current depending on the power of the transformer and the type of laminations used (hot-rolled or grain oriented).
There is maximum connection current when circuit-breaker closing takes place, corresponding to the voltage passing through zero.
A further result to be guaranteed is protection against faults in the low voltage winding and in the part of the connection between this and the circuit-breaker on the secondary, thus avoiding the use of fuses with rated current which is too high, in order to ensure tripping within a short time even under these fault conditions.
Rapid calculation of the short-circuit current at thesecondary terminals of the transformer and on
the supply side of the circuit-breaker on the secondary,if installed at a significant distance, allows the tripping timeto be verified on the fuse blowing curve.
The usage table given below takes both the required
conditions into account, i.e. rated current high enough toprevent untimely fuse blowing during the no-load connectionstage and, in any case, of a value which guarantees
protection of the machine against faults on the low voltage side.

Altitude
The insulating properties of the air diminish as the altitude increases. This must be taken into account with regard to the external insulation of the equipment.
The phenomenon must always be considered when the insulating components of equipment that must be installed at more than 1000 m above sea level are designed.
In this case, one must consider a correction coefficient that can be taken from the graph on the following page, created in accordance with the indications provided by Standards IEC 62271-1.
The example below gives a clear interpretation of the indications described above.

In this case, equipment with 17.5 kV rated voltage characterized by 38 kVrms insulation levels at power-frequency with 95 kVp impulse withstand voltage is required for installations at an altitude of 2000 m above sea level with 12 kV operating voltage.
