【Summary】
GCK low-voltage taking out type switch board is suitable
for exchanging 50Hz, 660V and the following three-phase
Line five make power transmission and distribution system.
Use as what the power plant , transformer substation ,
worker's vast enterprise and the skyscraper of the power
system are controlled by the electricity , feed , illumination
and motor.
This product accords with IEC 439-1<Low-voltage complete
set of switch equipment and controlling the equipment>；GB7251.1—1997<Low-voltage
complete set of switch equipment and controlling the first
part of equipment, test and test the complete sets with
some patterns in pattern>and ZBK36001-89<Low-voltage
taking out type complete set of switch equipment>Standard.
GCK low-voltage taking out type switch board , adopts
advanced assembling the structure and making the unit
up , person who take out make up unit pile load with in
the compartment , it protects the grade as IP30 on close
metal cupboard body, advantage of have safe , reliable
, compactness , convenient , flexible etc.
GCK low-voltage switch board , has special-purpose measurement
cupboards, can meet the electric power system to the low-voltage
demand that measures .
GCK low-voltage switch board , has special-purpose static
condenser cupboards, as compensating the using of inactive
power.
【Normal service condition】
1、Ambient air temperature high level cadre +40, lower
than- 5, and 24 hours its average temperature is not
higher than +35 degrees Centigrade .
2、Air clean, relative humidity when +40 of maximum temperature
, exceed 50% ; In lower temperature, allow to have higher
humidity, for example: +20 degrees Centigrade is 90%
at; Allow because temperature change may produce congeal
and revealing.
3、The height above sea level does not exceed 2000m .

【Structure
characteristic】
Body structure
of the cupboard:
GCKl low-voltage switch board of taking out etc. for
all assembling type combining structure, the basic skeleton
adopts the special-purpose material to assemble , cupboard
body skeleton , part external dimension turn on hole size
press the basic modulus E =20mm change.
Fasten because of all structure of frame with screw
connection , is it weld out of shape with stress to avoid,
have improved the precision.
Every cupboard body is separated into three parts, namely
main bus bar room for the horizontal bus bar to run through
on the top , the part in the front is separated into a
small room of several function units with the baffle ,
the height is 1760mm after making up, it is the cable
room partly to be following, contain the support in the
room , is used for laying and passing in and out the cable.
Having set up the vertical
bus bar behind the small room of the taking out type function
unit, the vertical bus bar utilizes the branch bus bar
and horizontal bus bar to link, each taking out type function
unit, it is linked in the position and vertical bus bar
that putting through. The cupboard carries the metal which
is equipped with the ventilator and seals the board; The
top is while needing to pass in and out the line, adopt
and seal the board insulatingly, the bottom seals the
board for the metal, wash and strike and leave the hole
on it, pass in and out with the sharp cable.
Taking out type systematic
structure:
The electric apparatus component of each function unit
is installed on a drawer , can make the whole unit break
away from the cupboard body , maintenance is safe , convenient.
The drawer is put in the wide cupboard body of 600mm,
there is " separating " , " test "
, " put through " in three seats. The power
in the light room of drawer enters the thread side and
is equipped with the valve, the drawer is being "
tested ", " put through " to the position,
the valve is opened automatically, is " separating"
the position, the valve is being closed automatically.
Small room door and return circuit main switch have
interlock , close main switch little room door can be
opened, can also unblock and open the door under the special
circumstances.
The main return circuit
electric current is and following in 100A, the height
of small room is 220mm; 45A and the following return circuit
, can generally install two drawers side by side . The
height of small room of return circuit of 200A , 400A
is generally 440mm, the small room of the return circuit
of 600A is generally 660mm.
Bayonet
systematic structure：
Main return circuit electric current>, at the 630A
, adopt frame posture circuit breaker of structure of
injecting etc. , is it push into spiral shell's pole finish
putting through and disconnection with generatrix to sway
with gear shift.
The regular installation of other electric apparatus
components besides main switch is in the small room.
Systematic structure of regular
type：
Measuring the unit and static
condenser cupboard, adopt the regular type to be installed,
all electric apparatus components are installed on the
crossbeams or mounting plates of the switch board .
