6/63
6 Fixed-Mounted Circuit-Breaker Switchgear Type 8DA and 8DB up to 40.5 kV, Gas-Insulated Siemens HA 35.11 2014
Requirements
Environmental independence
The enclosed high-voltage part of 8DA and 8DB switchgearis suitable for applications under aggressive ambientconditions, such as: Saline air
Air humidity
Dust
Condensation.
It is tight to ingress of foreign objects, such as: Dust
Pollution
Small animals.
The application is independent of the site altitude.
Compact design
Thanks to the use of SF6insulation, compact dimensions arepossible.
Thus:
Existing switchgear rooms can be used effectively New constructions cost little
Costly city-area space is saved.
Maintenance-free design
Switchgear housings designed as sealed pressure systems,maintenance-free switching devices and enclosed cableplugs ensure: Maximum supply reliability
Personnel safety
Sealed-for-life design according to IEC 62271-200(sealed pressure system)
Reduced operating costs
Cost-efficient investment.
Innovation
The use of digital secondary systems and combinedprotection and control devices ensures Clear integration in process control systems
Flexible and highly simplified adaptation to new systemconditions and thus to cost-efficient operation.
Service life
Under normal operating conditions, the expected servicelife of gas-insulated switchgear 8DA and 8DB is at least35 years, probably 40 to 50 years, taking the tightness of
the enclosed high-voltage part into account. The service lifeis limited by the maximum number of operat ing cycles ofthe switching devices installed: For circuit-breakers, according to the endurance class
defined in IEC 62271-100
For three-position disconnectors and earthing switches,according to the endurance class defined in IEC 62271-102.

Logical mechanical interlocks prevent maloperation
Make-proof earthing by means of the vacuum circuit-
breaker.
Security of operation
Hermetically sealed primary enclosure independent ofenvironmental effects (pollution, humidity and smallanimals)
Maintenance-free in an indoor environment according toIEC 62271-1
Two-phase and three-phase short-circuits between theprimary conductors are excluded by the single-poleprimary enclosure
In isolated or compensated systems, low-currentearth-fault currents are self-extinguishing
Operating mechanisms of switching devices accessibleoutside the primary enclosure (switchgear housings)
Metal-enclosed, plug-in inductive voltage transformersmounted outside the SF6switchgear housings
Current transformers as ring-core current transformersmounted outside the SF6switchgear housings

A metal bellows is used for gasketless separation betweenthe SF6insulation and the vacuum (already used withsuccess for over 2 million vacuum interrupters).
Trip-free mechanism
The vacuum circuit-breaker is fitted with a trip-freemechanism according to IEC 62271-100.
Switching duties and operating mechanisms
The switching duties of the vacuum circuit-breaker aredependent, among other factors, on its type of operating
mechanism.Motor operating mechanism Motor-operating stored-energy mechanism For auto-reclosing (K) For synchronization and rapid load transfer (U)Further operating mechanism features Located outside the switchgear housings in the operating
mechanism box and behind the control board
Stored-energy spring mechanism for 10,000 operating cycles
Optional:Stored-energy spring mechanism for 30,000 operating cycles.
Operating mechanism functions
Motor operating mechanism1)(M1 *)In the case of motor operating mechanism, the closing springis charged by means of a motor and latched in the chargedposition (spring charged indication is visible). Closing iseffected either by means of an ON pushbutton or a closingsolenoid. The closing spring is recharged automatically (forauto-reclosing).

Vacuum circuit-breaker
Components
Secondary equipment
The scope of the secondary equipment of the vacuumcircuit-breaker depends on the type of application and offersa wide range of possible variations, allowing almost everyrequirement to be satisfied.
Closing solenoid Type 3AY15 10 (Y9 *)
For electrical closing.
Shunt releases
Types: Standard: 3AY15 10 (Y1 *) Option: 3AX11 01 (Y2 *), with energy store
Tripping by protection relay or electrical actuation.
Undervoltage release
Type 3AX11 03 (Y7 *)
Comprising:
Energy store and unlatching mechanism Electromagnetic system, which is permanently connected
to voltage while the vacuum circuit-breaker is closed;tripping is initiated when this voltage drops
Connection to voltage transformers possible.
Anti-pumping
Function: If constant CLOSE and OPEN commands arepresent at the vacuum circuit-breaker at the same time,the vacuum circuit-breaker will return to the open positionafter closing. It remains in this position until a new CLOSEcommand is given. In this manner, continuous closing andopening (= pumping) is avoided.
Circuit-breaker tripping signal
For electrical signaling (as pulse > 10 ms), e.g. to remotecontrol systems, in the case of automatic tripping(e.g. protection)
Via limit switch (S6 *) and cutout switch (S7 *).
Varistor module
To limit overvoltages to approx. 500 V for protectiondevices (when inductive components are mounted in thevacuum circuit-breaker)
For auxiliary voltages 60 V DC.
Auxiliary switch Type 3SV9 (S1 *)
Standard: 12 NO + 12 NC.
Position switch
Type 3SE4 (S4 *)
For signaling closing spring charged.
Mechanical interlock
Mechanical interlocking to the three-position disconnector
During operation of the three-position disconnector,the vacuum circuit-breaker cannot be operated.

Protecting, controlling and monitoring are the basic require-ments placed on a complete bay controller across all tech-nology generations. The properties the user expects frommodern bay controllers are: multifunctionality, reliability,safety and communication capability.The increasing integration of many functions in one multi-
functional device leads to an optimally supported engineer-
ing process, IT security, service and testability, or simpleand safe operability of the devices and tools.On the following pages you will find functional descrip-tions for some selected devices. The low-voltage compart-ment can accommodate all customary protection, control,measuring and monitoring equipment available on the
market:
