Features
SIMOSEC ANSI switchgear
is a factory-assembled, typetested, three-phase, metalenclosed, indoor switchgear
according to ANSI/IEEE
C37.20.3 * for single busbars.
Technical features
Reliability
• Air-insulated indoor
• Type (design) tested with
Typical uses
• Three-pole primary enclosure
SIMOSEC ANSI switchgear is
used for power distribution in
distribution systems with
feeder currents up to 1200 A.
• Phases arranged one behind
Modular space-saving design
allows use in
• Substations, customer trans-
fer substations, distribution
substations and switching
substations of power supply
and public utilities
• Public buildings, such as
high-rise buildings, railway
stations, hospitals
• Industrial plants
switchgear
• Gas-insulated, maintenance-
free switching functions for

During the switching movement, the compression vanes
generate a pressure difference
between the subchambers.
The SF6 gas flows through a
nozzle, causes a directional
blow-out of the breaking arc
and quenches it rapidly.
Switch positions:

Compression vanes, which
rotate in conjunction with the
switch shaft, divide the arcing
chamber into two subchambers

Operating mechanisms
Spring-operated/storedenergy mechanisms can be
equipped with a shunt release. Remote electrical
tripping of the two/threeposition switch-disconnector
is possible via the magnetic
coil of the shunt release,
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 switchdisconnector.

Mode of operation
For the ready-for-service indicator, a gas-tight measuring
box is installed on the inside
of the switchgear vessel.
A coupling magnet, which
is fitted to the bottom end
of the measuring box, transmits its position to an outside
armature through the stainless steel switchgear vessel.
This armature moves the
ready-for-service indicator of
the switchgear.
While changes in the gas
density during the loss of
gas, which are decisive for
the insulating capacity, are
displayed, temperaturedependent changes in the
gas pressure are not. The gas
in the measuring box has the
same temperature as that in
the switchgear.

Cable testing
• For cable testing
– the installation and
operating instructions of
the switchgear
– the information on manufacturer-dependent cable
sealing ends
– the cable version
(e.g. paper-insulated massimpregnated cables, PVC
cables or XLPE cables)
must be observed.
• For switch-disconnector
feeders
• DC voltage test
before the test:
Remove or disconnect any
voltage transformers at the
cable connection in SIMOSEC
ANSI switchgear.
SIMOSEC ANSI switchgear
for rated voltages up to
27.6 kV can be subjected to
cable tests at a max. DC test
voltage of 70 kV. The voltage
at the busbar may be 27.6 kV

Climate and ambient
conditions
SIMOSEC ANSI switchgear may
be used, subject to possible additional measures – e.g. panel
heaters or floor covers –
under the following ambient
conditions and operating
temperatures:
• Ambient conditions
– Natural foreign materials
– Chemically active pollutants
– Small animals
• Operating temperatures
The operating temperatures
are classified according to
ANSI/IEEE C37.20.3
SIMOSEC ANSI switchgear is
largely insensitive to climate
and ambient conditions by
virtue of the following features:
• No cross insulation for
isolating distances between
phases
* VLF = Very Low Frequency.
Refer to IEEE Standard 400.2-2004
“IEEE Guide for Field Testing of
Shielded Power Cable Systems
Using Very Low Frequency (VLF)”.
For cosine-rectangular waveform,
the rms value is taken as equal to
the peak value. For sinusoidal
waveform, the rms value is 0.707
times the peak value, if distortion is
less than 5 %.
