6 Fixed-Mounted Circuit-Breaker Switchgear Type NXPLUS up to 40.5 kV, Gas-Insulated Siemens HA 35.51 2012
Requirements
Environmental independence
Hermetically tight, welded switchgear vessels made ofstainless steel as well as single-pole solid insulation makethe parts of the primary circuit under high voltage ofNXPLUS switchgear Insensitive to certain aggressive ambient conditions,
such as: Air humidity Dust
Condensation Tight to ingress of foreign objects, such as:
Dust Pollution Small animals Humidity
Independent of the site altitude.
Compact design
Thanks to the use of SF6insulation, compact dimensions arepossible up to 40.5 kV.Thus:
Existing switchgear rooms can be used effectively New constructions cost little Costly city-area space is saved.
Maintenance-free design
Switchgear vessels 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)
Installation, operation, extension and replacementwithout SF6gas work
Reduced operating costs Cost-efficient investment No maintenance cycles.
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 NXPLUS is at least 35 years,probably 40 to 50 years, taking the tightness of the
hermetically welded switchgear vessel into account. Theservice life is limited by the maximum number of operatingcycles of the switchgear 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.
Personal safety
Safe-to-touch and hermetically sealed primary enclosure Cable terminations, busbars and voltage transformers are
surrounded by earthed layers All high-voltage parts including the cable terminations,
busbars and voltage transformers are metal-enclosed or
metal-coated. Capacitive voltage detecting system to verify safe isolation
from supply
Operating mechanisms and auxiliary switches safelyaccessible outside the primary enclosure (switchgearvessel)
Due to the system design, operation is only possible withclosed switchgear enclosure
Standard degree of protection IP 65 for all high-voltageparts of the primary circuit, IP 3XD for the switchgearenclosure according to IEC 60529 and VDE 0470-1
High resistance to internal arcs by logical mechanicalinterlocks and tested switchgear enclosure
Panels tested for resistance to internal faults up to 31.5 kA 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 (IEC 62271-1and VDE 0671-1)
Operating mechanisms of switching devices accessible
outside the primary enclosure (modules) Metal-coated or metal-enclosed, plug-in inductive voltagetransformers mounted outside the SF6switchgear vessel
Current transformers as ring-core current transformersmounted outside the SF6switchgear vessel
Complete switchgear interlocking system with logicalmechanical interlocks
Welded switchgear vessels, sealed for life Minimum fire load Type and routine-tested
Standardized and manufactured using numericallycontrolled machines
Quality assurance in accordance with DIN EN ISO 9001
More than 500,000 switchgear panels of Siemens inoperation worldwide for many years
Option: Resistance against earthquakes (single busbaronly).

Components
Features
According to IEC 62271-100 and VDE 0671-100(for standards, see page 53)
Application in hermetically welded switchgear vessel inconformity with the system
Climate-independent vacuum interrupter poles in the
SF6-filled switchgear vessel Maintenance-free for indoor installation according to
IEC 62271-1 and VDE 0671-1
Individual secondary equipment A metal bellows is used for gasketless separation of the
SF6insulation and the operating mechanism (already usedwith success for over 2 million vacuum interrupters).
Trip-free mechanism
The vacuum circuit-breaker is fitted with a trip-freemechanism according to IEC 62271 and VDE 0671.
Switching duties and operating mechanisms
The switching duties of the vacuum circuit-breaker are
dependent, among other factors, on its type of operatingmechanism.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 vessel in the operating
mechanism box and behind the control board Stored-energy spring mechanism for 10,000 operating cycles.
Operating mechanism functions
Motor operating mechanism 1)(M1 *)
In the case of motor operating mechanism, the closingspring is charged by means of a motor and latched in thecharged position (spring charged indication is visible).Closing is effected either by means of an ON pushbuttonor a closing solenoid. The closing spring is rechargedautomatically (for auto-reclosing).

Vacuum circuit-breaker
Components
Secondary equipment
The scope of the secondary equipment of the vacuum circuit-breaker depends on the type of application and offers a widerange of possible variations, allowing almost every require-ment to be satisfied:
Closing solenoid
Type 3AY15 10 (Y9 *) For electrical closing.
Shunt release
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 *)
Consisting of: 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(mechanical and electrical)
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 remote con-trol 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: 6 NO + 6 NC, free contacts thereof 1)2 NO + 2 NC
Option: 12 NO + 12 NC, free contacts thereof 1)8 NO + 8 NC.
Position switch
Type 3AX4 (S41, S42, S16 *)
For signaling closing spring charged
For circuit-breaker blocked indication.Mechanical interlocking
Mechanical interlocking to the three-position disconnector During operation of the three-position switch, the vacuum
circuit-breaker cannot be operated.

ComponentsPanel connection with inside cone
Panel connection withinside-cone plug-in system orsolid-insulated bar
Features
For circuit-breaker and
disconnector panels Inside-cone plug-in systemaccording to DIN EN 50181
For connection cross-sectionsup to 630 mm2
Up to 4 cables with inside-coneplug size 2
Up to 3 cables with inside-coneplug size 3
With cable bracket, type C40according to DIN EN 50024
Option: Access to the cablecompartment only if the feeder has
been isolated and earthed For thermoplastic-insulated cables Cable routing downwards,
cable connection from the front Inside-cone plugs are not
part of the scope of supply Additionally one outside-cone
termination (up to 36 kV) or oneinside-cone socket (40.5 kV) forconnection of a voltage transformer
Instead of an inside-cone plug,the cable connection can also bedesigned for a solid-insulated bar.
Surge arresters
Inside-cone sockets can beequipped with a surge arresterinstead of an inside-cone cable plug
Surge arresters are available forplug-in sockets size 2 or 3
Surge arresters are available withdischarge currents of 5 kA and10 kA.
Connection options
4 cables per phase (option: surge arrester)Interface type 2
3 cables per phase (option: surge arrester)Interface type 2 or 3
