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).

Reliability

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).

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 *)

circuit-breaker cannot be operated.

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
