These are
the medium voltage switchgears designed for use in secondary
distribution systems up to *0,5 kV, in compact kiosk type
transformer substations, in industrial facilities and indoor
spaces. All functional units which may be required in a switching
and distribution centre can be easily installed side by side. By
safely using the Switchgears which are produced in the factory with
all routine and type tests conducted, they can be commissioned in a
very short period practically.
Isolating and breaking processes are carried out in SF6 gas
environment and the busbars compartment in air. Thanks to this, a
safe isolating and breaking process is ensured and dimensions have
been minimised.modular Switchgears, due to their compact
dimensions, can be easily and safely used in kiosk type transformer
stations.
modular Switchgears consist of 4 main compartments
Cable connection and switching section
Busbar section
Operating mechanism section
Low voltage section
CABLE CONNECTION and SWITCHING SECTION
Network cables are connected to the connection terminal located
under the earthing switch. In this section, load break switch,
switch disconnector, circuit breaker and earthing switch are
located the as the switching element depending on the cubicle type.
MV fuses and striker pin transmission mechanisms are located in
fuse-switch combination.
Switch disconnector or Load Break Switch within the epoxy resin
frame has been completely separated from the busbar section and
cable connection section by means of a sheet metal plates..Single
-core cables up to **0 mm can easily be connected to this
section.
Sleeves and braces are present at the cable entrance in order to
allow the cables to stand firm inside the cubicle. The earthing
switch must be closed in order to access this section.
BUSBAR SECTION
When the modular Switchgears are installed side by side, the busbar
connection between the Switchgears is conducted by 3 pieces of
busbars with proper sections. Access to busbar section is provided
through the top cover of the cell.
OPERATING MECHANISM
SECTION
In this section, switch disconnector and/or load break switch,
driving mechanism elements of the earthing switch exist.
Optionally, this part can be installed with motorised spring
charging system.
LV BOARD SECTION
This section contains terminal blocks, LV fuses, thermostat,
measuring instruments and protection relays. When the cubicle is
energised (busbars and cable) processes can be performed in LV
board.
Basic Interlocking
Systems
LBS can be closed only when the cell gate is closed and grounding
isolator is open.
Earthing Switch can be closed when the LBS is open
Cubicle door can be opened when the earthing switch is
closed.
LBS can not be closed when the cubicle door is open.
Switchgears with Circuit Breakers;
LBS (in
the coupling cubicle) can be opened only when the breaker is in on
position.
LBS or breaker can be locked in ON position.
Earthing Switch can only be closed when it is open.
Cubicle door can not be closed when open.
Cubicle Door can be opened only if the breaker is locked in ON
position, if the LBS is open and the earthing switch is not
closed.
STRUCTURAL
PROPERTIES
Switchgears have been designed under complete modular structure, in
consideration of functionality, appearance and security features.
Cubicle carcasses are manufactured of 2mm hot dip galvanized sheet
metal and with its galvanise thickness of **5gr/m² which is above
the industry standards, it is not subject to any deformation even
under the most damp mediums.
In all epoxy resin parts used in Switchgears (support and
capacitive isolators, switch disconnector frame etc.) are produced
in the epoxy resin facility inside our factory and each is
subjected to the relevant tests prior to entering in main
switchgear assembly line.
STANDARD and OPTIONAL
ACCESSORIES
Toroidal type current transformer
-Cast resin type current transformer
DIGITAL PROTECTION AND CONTROL
RELAYS
In Switchgears various types of relays are used with
various
protection, measurement and control properties. In consideration of
the
Customer and Project requirements, the selected relays are
dispatched
from our factory with the desired set values. The PNC PAC E***0
relay
which is frequently used and which offer *0 & *1 over current
and ground
protection functions, operate in full compliance with Ulusoy
toroidal
current transformers and in line with the customer demands, the
relays of
different manufacturers can also be used in our
Switchgears.
LINE FAULT
INDICATORS
The devices supplied from various manufacturers which can
be
mounted into control board or concrete kiosk in order to indicate
the
phase and ground faults are offered optionally with our
Switchgears.
METERING
INSTRUMENTS
The selection of the metering instruments in our Switchgears, such
as
ammeter, voltmeter, gauge, energy analyser is made in line with
the
customer and project requirements.
MV FUSES
In Switchgears, high breaking capacity MV fuses are
used, after being selected as per the transformer power.
REMOTE CONTROL
By means of the remote control which is offered in
Switchgears as default, it is possible to remote control the
operation on the cell from up to 5 meters.
BUSBARS
The busbars which are used for connection of the Switchgears
with
each other are manufactured from high conductivity aluminium or
copper and insulated with heat-shrink tubes.
