SecoGear 24kV-27kV Air Insulation Switchgear
2
General
Summary
This publication contains the information required for
installation, commissioning, operation and maintenance
of SecoGear. SecoGear is three-phase, metal enclosed, air-
insulated factory assembled switchgear. SecoGear is type-
tested and suitable for indoor applications up to 27 kV. The
panel is designed with withdrawable modules and is fitted with
a single busbar system. The withdra
wable parts are equipped
with circuit breakers, voltage transformers, fuses or current
transformers.
Details of the technical design and configuration of individual
switchgear, such as the technical data, detailed part lists for the
individual panels and comprehensive circuit documentation etc.,
can be found in the relevant order documents.
For correct usage of the switchgear, please read this manua
l
carefully. It is always advisable to use the manual for all
operations regarding installation, commissioning, operation and
maintenance of SecoGear air-insulated switchgear.
These instructions are also used as references for personnel to
carry on regularly maintenance of the switchgear.
Standard and Specification
• SecoGear complies with the standards and specifications for factory-assembled, metal enclosed and type tested high voltage
switchgears to IEC publications as given below.
IEC62271-100: 2008 …………… High-voltage alternating current circuit breakers.
IEC62271-200: 2003 …………… AC Metal enclosed switchgear and control gear for rated voltages above
1kV and up to 52kV.
IEC62271-102: 2001 …………… High-voltage alternating current Disconnector and Earthing Switches.
IEC62271
-1: 2007 …………… The common specification for high voltage switchgear and control gear
simple Standards
IEC60529:1989 …………… Degrees of protection as provided by enclosures (IP Code)
The switchgear has the following degrees of protection:
IP 4X applies for the enclosure and IP 2X applies for the partitions.
All other corresponding IEC publications, national or local safe
ty regulations must be followed during the installation and operation of
the switchgear. In addition, any project specific advice from GE must be considered.
