The NPS design is based on many years o experience with

installations around the world. With the NPS, ABB delivers reliable

operation in all climatic conditions and congurations. In addition,

the NPS can be either manually or remotely controlled, with the

option o incorporation into automated networks as a sectionalizer.

Thanks to its modular construction and important design eatures,

the NPS is a key component in creating uture smart grids.

The modular NPS design allows or a wide range o

accessories or various applications or outdoor air-insulated

switches. The NPS can be expanded and adapted to

changing distribution network needs, even ater installation.

The NPS oers three types o insulators - porcelain, epoxy

(cycloaliphatic) and silicone.

The epoxy and silicon insulators provide reduced weight,

resistance to mechanical shock and good perormance in heavy

polluted areas. In order to heavily polluted achieve high creepage

perormance, the NPS oers a wide range o insulators.

The NPS is provided with breaking whips as standard. I higher

interrupting ratings are required, breaking chambers are provided.

Technology reviewNPS technology

1. Wide range o various equipment (third insulator, use bases, earthing switch rom the rocking side, use base integrated with NPS, UEKO3A1 &

UEKO3B1 manual operating mechanism | 2. Various types o insulators

The main current carrying path is electrolytic copper, silver plated

to ensure a suitably low level o contact resistance. The design

o the main contacts consists o copper contact tips xed by

stainless steel springs. This design ensures sel positioning o

the main contacts in the closed position. In addition, this design

requires a lower amount o orce or closing and opening the

disconnector. The short circuit withstand o the NPS is increased

as a result o the eect o electrodynamic orces during short

circuit current fow through the main current path. In addition,

the tips may be reversed by 180 which extends the lie o the

contacts. This is a simple operation using ordinary pliers.

All steel components are coated with zinc galvanizing which

provides a high level o corrosion resistance All copper

components are silver-plated with the exception o terminals,

which are coated with tin to allow line terminals, aluminium and

copper, to be connected to the NPS without degrading their

perormance. Flexible copper parts o the NPS are coated with

tin, aluminum components are made o special aluminum alloy to

ensure high resistance to extreme ambient conditions. For special

customer requirements, acetal resin insulators are available or

disconnectors rated up to 24 kV, or composite insulators or up to

36 kV used in connection rods between the operating mechanism

and switch.

All standardized asteners are zinc galvanized or stainless steel.

This allows the NPS switch disconnector to provide long-term

operation even in the harshest environments.


Breaking chambers

There are our dierent rated current breaking versions used in

the NPS. Using one o the 2 types o chambers it is possible to

achieve signicant values o breaking rated currents:

standard fexible breaking whips or switching-o small currents

(up to 25 A or 24 kV, up to 40 A or 12 kV),

special (K1) breaking whips or switching o higher currents

(up to 50 A at 24 kV, up to 80 A or 12 kV),

air type breaking chamber (K4) with breaking capacity up to

250 A (24 kV),

air type breaking chamber (K5) with breaking capacity up to

630 A (24 kV).

Control cabinets

The NPS control cabinets are designed or remote control and

local automation applications o NPS switch disconnectors and

other similar types with up/down operating movement.

Together with the ABB REC601/603 or REC 523 monitoring and

control units both simple applications such as remote open/close

operations and more sophisticated auto sectionalizing schemes

and measurements can be realized.

Basic unction o REC601/603:

1. Controls: one (REC601) or three (REC603) drives,

2. GPRS communication3. Module o battery charging with temperature compensation,

deep discharge protection, battery monitoring and testing

in a variety o dierent positions, with either manual or remote

control.

Disconnectors equipped with electric drives can be used in

system automation solutions or distribution networks using the

remote control or auto-closing unctions. In this case, in addition

to the motor operating mechanism the NPS will also be equipped

with the latest automation systems. So in this application, the

NPS switch disconnectors will become an integral part o the

development o Smart Grids.

Remarks:

1. Standard short circuit withstand is 16/40 kA or 24 kV, version with

silicon insulators (increased creepage distance) provides 20/50 kA.

2. When using 3rd insulator, SAs or CTs it is not possible to use

an integrated earthing switch at the same site o the NPS unit.

In this case, reer to column 14 and select loose installation

earthing switches i necessary.

3. Fuse bases or separate installation or OFCD type uses are

available only with epoxy insulators version.

4. Selection o KOHU CTs electrical parameters should be dened

according to the separate KOHU CT catalogue.


5. ABB recommends SAs POLIM D and POLIM K type.

6. When selecting any style code then just one choice is available

or the specic switch solution. Only the additional equipment

has multi-choice options.

7. Please note that 36 kV versions have limited versions o additi-

onal equipment such as: earthing switches, dierent pole

installation methods, SAs, uses, insulator types. Thereore,

especially when selecting 36 kV versions we recommend dis-

cussion o the required solution with your local ABB

representative.
