7 Components

7.1 Three-position switch-disconnector

Features • The three-position switch-disconnector is designed for a rated voltage of up to 36 kV• Switching functions as general-purpose switch-disconnector (class E3) according to

IEC 62271-103, IEC 62271-102 / VDE 0671-102 and IEC 62271-105 / VDE 0671-105• Designed as a three-position switch incorporating the functions of a switch-disconnector

and a make-proof earthing switch with the switch positions CLOSED - OPEN - EARTHED

Fig. 3: Operation of three-position switch

Mode of operation The operating shaft forms one unit together with the three contact blades. Due to the arrangement of the fixed contacts (earth - busbar), it is not necessary to interlock the CLOSE and EARTHING functions.

Closing operation During the closing operation, the operating shaft with the moving contact blades changes from the OPEN to the CLOSED position.

The force of the spring-operated mechanism ensures a high closing speed and a reliable connection of the main circuit.

Opening operation During the opening operation, the arc is caused to rotate by the arc-suppression system, thus preventing the development of a fixed root. This very effective arc extinction provides short arcing times. The isolating distance in gas established after opening satisfies the conditions for isolating distances according to IEC/EN 62 271-102 / VDE 0671-102 and IEC/EN 62 271-1 / VDE 0671-1.

Earthing operation The "EARTHING" operation is implemented by the turning movement of the operating lever (rotation, if required) from the "OPEN" to the "EARTHED" position.


Description Operating mechanisms for the three-position switch

Common features • Mechanical endurance of more than 1000 operating cycles• Manual operation with the help of a slip-on operating lever• Option: Motor operation of the disconnecting function• Control board with accordingly cut-out switching gate prevents the three-position switch-

disconnector from being switched directly from the CLOSED via the OPEN to the EARTHED position

• Two separate actuating openings are provided for unambiguous selection of either the load-break function or make-proof earthing

• Operation via rotary movement, operating direction according to IEC/EN 60 447(VDN/VDEW recommendation)

The switching movements are performed independently of the operating speed.

Spring-operatedmechanism

The spring-operated mechanism is used for the three-position switch-disconnector in ring-main panels (as ring-main switch). The switching movements are performed independently of the operating speed.

Design The three-position switch-disconnector is operated through a gas-tight welded bushing at the front of the switchgear vessel.

Description


Features of

spring-operated/stored-energy mechanism

During the charging process, the closing and opening springs are charged. This ensures that the switch-disconnector/fuse combination can switch off all types of faults reliably even during closing.

Closing and opening is done via pushbuttons after removing the operating lever.

An energy store is available for tripping by means of an operating HV HRC fuse or via a shunt release (f-release).

After the HV HRC fuse has tripped, a red transverse bar appears on the "fuse tripped" indicator.

Manual operation for the EARTHING function with the help of a slip-on operating lever.

Mode of operation ofspring-operated/

stored-energy mechanism

The spring-operated/stored energy mechanism is used for three-position switch-disconnectors in transformer panels (as transformer switch). First, the operating springs are charged with the "spring charged" operation. Then, closing and opening is done via separate pushbuttons. An energy store is available for the opening process when an HV HRC fuse or a shunt release (f-release) trips. No additional charging process is required for the energy store. This energy store is already charged by switching from the "spring not charged" position to the "spring charged" position. This pre-charged energy store ensures that the switch-disconnector/fuse combination can switch off all types of faults reliably even during closing. After the HV HRC fuse has tripped, a red transverse bar appears on the "fuse tripped" indicator.

Generally, the switchgear is equipped with an operating lever ejection system, which means that, after charging the springs, the operating lever is ejected, thus preventing it from being left inserted accidentally. On the customer's request, the operating lever ejection system can be ommitted.

ATTENTION!Risk of injury! When charging the spring, the operating lever is inserted in the actuating opening. If no operating lever ejection system is available, the operating lever rotates and can thereby injure the operator.

Remove operating lever before charging the spring.


Description

Mechanism operation Operating levers for charging the springs of the switch-disconnector and the make-proof earthing switch. Coding of the operating levers is optionally possible.

Operation• Local operation by momentary-contact rotary control switch (option)• Remote operation (standard) applied to terminal

Operating voltages for motor operating mechanisms and tripping coils• 24, 48, 60, 110, 220 V DC• 110 and 230 V AC 50/60 Hz• Power consumption: 80 W for AC and DC

Fig. 6: Motor unit with auxiliary switch block

Shunt release (optional) Spring-operated/stored-energy mechanisms can be equipped with a magnetic tripping coil (shunt release). Remote electrical tripping of the three-position switch-disconnector is possible via the magnet coil, e.g. transformer overtemperature tripping.

To avoid thermal overloading of the shunt release in the event of a continuous signal that may be applied, the shunt release is switched off via an auxiliary switch which is mechanically coupled with the three-position switch-disconnector.

In transformer feeders, continuity at the shunt release can only be tested when the operating lever is removed.

Description


Auxiliary switch

(optional)The operating mechanism of the three-position switch-disconnector can be optionally equipped with an auxiliary switch for the position indication. A motor operating mechanism is equipped with an auxiliary switch as standard.• For switch-disconnector function: CLOSED and OPEN: 1 NO + 1 NC + 2 changeover• For earthing switch function: CLOSED and OPEN: 1 NO + 1 NC + 2 changeover

Fig. 7: Auxiliary switch in the operating mechanism of the three-position switch-disconnector, for example in the ring-main feeder

Wiring Auxiliary switches, motor operating mechanisms or shunt releases are wired to terminal strips. The terminal strips are feeder-related and located above the operating mechanism assembly of the feeder concerned. Customer-side cable routing is made from the side to the terminal strip arranged on the operating mechanism assemblies.


Description 7.2 Interlocks

Mechanical interlocking • The switching gate prevents switching straight from CLOSED to EARTHED position, or from EARTHED to CLOSED position, as the operating lever must be re-inserted in the OPEN position.

• The cable compartment cover (HV HRC fuse compartment cover) can only be removed if the transformer feeder is earthed and the operating lever is removed. The three-position switch-disconnector can only be switched from the EARTHED position to another position if the cable compartment cover (HV HRC fuse compartment cover) is fitted.

• The cable compartment covers can only be removed when the associated feeder is earthed.• A closing lock-out (option) in the ring-main feeder prevents the three-position

switch-disconnector from being switched to the CLOSED position if the cable compartment cover is removed.

• A de-earthing lock-out in the transformer feeder (standard) and the ring-main feeder prevents the three-position switch-disconnector from being switched from EARTHED position to OPEN position if the cable compartment cover is removed.

• With stored-energy mechanisms, closing and opening is not possible if the operating lever is inserted.

• The locking device (option) of the switching gate can be padlocked in all three switch positions. The locking device can be padlocked so that no closing or no opening or no earthing is possible. The padlock can also be fitted in such a way that none of the three switching operations can be performed.

Electrical interlock If the operating lever for the three-position switch is inserted, the motor operating mechanism cannot be operated from remote or locally anymore.

7.6 Aligning and extending the switchgear

Features • Busbar extension possible on all individual panels and panel blocks (option)• Plug-in unit consisting of contact coupling and screened silicone coupling• Insensitive to pollution and condensation• Switchgear installation, extension or panel replacement is possible without gas work

Version Every switchgear block and every individual panel is optionally available with busbar extension on the right, on the left or on both sides. This offers a high flexibility for the creation of switchgear configurations whose functional units are lined up in any order. Local installation and lining up is done without gas work.

Lining up takes place as follows:• By the busbar couplings. Tolerances between adjacent panels are compensated by spherical

fixed contacts and the movable contact couplings with degrees of freedom in all axis directions.

• By safe dielectric sealing with screened silicone couplings that are externally earthed and adjustable to tolerances. The silicone couplings are pressed on with a defined pressure when the panels are interconnected.

• On free busbar ends, screened dummy plugs are inserted, each of which is pressed on through a metal cover. A common protective cover with a warning is fixed over all three covers.

• By guiding tension bolts for easier switchgear installation and fixing of adjacent panels.• By bolted panel joints with defined stops for the distances between adjacent panels and the

associated pressure of contact pieces and silicone couplings.

Switchgear installation, extension or replacement of one or more functional units requires a lateral wall distance ≥ 200 mm.

7.10 Ready-for-service indicatorThe switching-device vessels are filled with insulating gas at a relative pressure. The ready-for-service indicator for gas-insulated switching-device vessels located at the operating front of the switchgear panel shows through the green/red indication whether the gas density is in order.

Fig. 23: Ready-for-service indicator

Features • Self-monitoring, easy to read• Independent of temperature and external pressure variations• Independent of the site altitude• Only responds to changes in gas density• Option: Alarm switch "1NO + 1NC" for remote electrical indication

Description


Mode of operation

For the ready-for-service indicator, a gas-tight measurement box is installed inside the switching-device vessel.

A coupling magnet, which is fitted to the bottom end of the measurement box, transmits its position to an armature outside the switching-device vessel through the non-magnetizable switching-device vessel (magnetic coupling). This armature moves the ready-for-service indicator at the operating front of the panel.

While changes in the gas density during the loss of gas, which are decisive for the dielectric strength, are displayed, changes in the relative gas pressure resulting from temperature and external pressure variations are not. The gas in the measurement box has the same temperature as that in the switching-device vessel.

The temperature effect is compensated via the same pressure change in both gas volumes.

• The switchgear operates perfectly in a range between the rated filling level of 150 kPA and the minimum functional level of 130 kPA.

• If the gas pressure falls below 130 kPA, the switchgear must not be operated anymore. The ready-for-service indicator changes from the green area to the red area ("Not ready for service").

• When the ready-for-service indicator changes from the green to the red area or vice versa, the signaling switch is tripped.

Description


8.7 Gas leakage rate

Gas leakage rate The gas leakage rate is < 0.1% per year (referred to the absolute gas pressure).

8.8 Dielectric strength and site altitude

Dielectric strength • The dielectric strength is verified by testing the switchgear with rated values of short-duration power-frequency withstand voltage and lightning impulse withstand voltage according to IEC 62271-1 / VDE 0671-1.

• The rated values are referred to sea level and to normal atmospheric conditions(101.3 hPa, 20 °C, 11g/m3 humidity according to IEC 60071 and VDE 0111).

• The dielectric strength decreases with increasing altitude. For site altitudes above 1000 m (above sea level) the standards do not provide any guidelines for the insulation rating, but leave this to the scope of special agreements.

All parts housed inside the switchgear vessel which are subjected to high voltage are SF6-insulated against the earthed enclosure.

Site altitude The gas insulation at a relative gas pressure of 50 kPa (= 500 hPa) permits switchgear installation at any desired altitude above sea level without the dielectric strength being adversely affected. This applies also to the cable connection, as only screened cable T-plugs are used.

Panels with HV HRC fuses are permissible up to a site altitude of 1000 m above sea level.


Description 8.9 Selection of HV HRC fuse-links

Note toHV HRC fuse-links

According to IEC 60282-1 (2009) Clause 6.6, the breaking capacity of HV HRC fuses is tested within the scope of the type test at 87% of their rated voltage.

In three-phase systems with resonance-earthed or isolated neutral, under double earth fault and other conditions, the full phase-to-phase voltage may be available at the HV HRC fuse during breaking. Depending on the size of the operating voltage of such a system, this applied voltage may then exceed 87% of the rated voltage.

It must therefore already be ensured during configuration of the switching devices and selection of the HV HRC fuse that only such fuse-links are used, which either satisfy the above operating conditions, or whose breaking capacity was tested at least with the maximum system voltage.

In case of doubt, a suitable HV HRC fuse must be selected together with the fuse manufacturer.

Allocation of HV HRC fuses and transformers

The three-position switch-disconnector in the transformer feeder (transformer switch) was combined with HV HRC fuse-links and tested in accordance with IEC 62 271-105.

The transformer protection table below shows HV HRC fuse-links recommended for transformer protection. Furthermore, the switchgear also permits fuse protection of transformers up to ratings of 2000 kVA. Please contact us for such applications.

The protection table applies to:• Maximum ambient air temperature in the switchgear room of 40°C according to

IEC 62 271-1 considering the influence of the switchgear enclosure• Requirements according to IEC 62271-105• Protection of distribution transformers according to IEC 60787• Rated power of transformer (no overload operation)

The specified HV HRC fuses make SIBA are type-tested partial range fuses according toIEC 60 282-1. The dimensions correspond to DIN 43625. The HV HRC fuses have a thermal protection in form of a temperature-limiting striker tripping operating in case of defective HV HRC fuse-links or high overload currents.

Please contact us if you want to use HV HRC fuses from other manufacturers.

Basis for selection of HV HRC fuse-links:• IEC 60282-1• IEC 62271-105• IEC 60787• Recommendations and data sheets of fuse manufacturers• Permissible power loss in the switchgear enclosure at an ambient air temperature of 40° C

11.6 Preparing the foundation• A suitable foundation can be a false floor, a double floor or a reinforced-concrete

foundation. The reinforced-concrete floor must be equipped with foundation rails for supporting the panels.

• As for design and construction of the foundation, the relevant standards DIN 43 661 “Fundamentschienen in Innenanlagen der Elektrotechnik” (Foundation rails in electrical indoor installations) and DIN 18 202 “Maßtoleranzen im Hochbau” (Blatt 3) (Measuring tolerances in structural engineering (Sheet 3)) apply.

• The dimensions of the floor opening and the fixing points of the switchgear frame are given in the switchgear documentation.

• Determine level differences between the installation surfaces of the panels using a measuring sheet, and compensate them with shims.

Stipulations for evennessand straightness

Installation


11.7 Comments on electromagnetic compatibilityTo achieve appropriate electromagnetic compatibility (EMC), some basic requirements must be observed while erecting the switchgear. This applies especially to the installation and connection of external cables and wires.

Basic measures for ensuring EMC are already taken during design and assembly of the switchgear panels. Among other things, these measures include:• The low-voltage compartment is an integral part of the panel, which means that the

protection and control devices with the internal wiring are metal-enclosed.• Reliable earth connections of the frame parts via toothed contact washers or locking

washers.• Inside the panel, wires are laid in metal ducts.• Spatial separation of sensitive signal wires from wires with high interference voltage levels.• Limitation of switching overvoltages of inductive loads (e.g. relay or contactor coils, motors)

by means of protective circuits with diode, varistor or RC element.• Within the LV compartment, the secondary devices are mounted in defined zones.• Shortest possible connection between corresponding modules in subracks.• Consideration of the magnetic leakage fields of conductor bars and cables.• Protection of subracks and wiring backplanes against interference by perforated shielding

plates.• Large surface bonding between all modules and devices as well as bonding to the earthing

conductor of the switchgear assembly.

These measures basically enable proper operation of the switchgear itself. The planner or operator of the switchgear must decide whether additional measures are required depending on the electromagnetic environment where the switchgear is installed. Such measures must be implemented by the installation company in charge.

In an environment with heavy electromagnetic interference it may be necessary to use shielded cables and wires for the external connections in order to avoid interferences in the low-voltage compartment and thus, undesired influences on the electronic protection and control or other automation devices.

Cable shields must be electrically bonded to be able to carry high frequencies, and contacted concentrically at the cable ends.

The shields of cables and wires are connected and earthed in the low-voltage compartment.

Connect the shields to earth potential - with high electrical conductivity and all around as far as possible. Protect the contact surfaces from corrosion in case of humidity (regular condensation).

When laying cables into the switchgear assembly, separate the control, signaling and data cables and other lines with different signal and voltage levels by laying them on separate racks or riser cable routes.

Corresponding to the different shield designs, there is a number of methods to perform connection. The planning department or site management determines which of the methods will be used, taking EMC requirements into account. The preceding points should always be taken into account.

The shield is connected to cables or wires with clamps contacting all around. If low demands are placed on EMC, it is also possible to connect the shield directly to earth potential (combine or twist the shield wires) or via short cable connections. Use cable lugs or wire-end ferrules at the connecting points.

Always keep the connecting leads of the shields as short as possible (< 10 cm).

If shields are used as protective earth conductors at the same time, the connected plastic-insulated lead must be marked green/yellow over its entire length. Non-insulated connections are inadmissible.
