General
China Knkong-electric produces GCK type switch panel is an improved
economical type of MNS. The vertical row has no plastic functional
panels and the door is fixed.
After opened the door, the drawer can be pulled out.
G--cabinet structure;
C--drawable type;
K--control center.
Feature
1. The main body of the GCK drawer type switch cabinet is steel
plate, which is positioned by angle plates, connected by bolts, and
has no welded structure. Modular parts. The cabinet is divided into
three isolation areas: busbar room, functional unit room and cable
room, which can effectively prevent the spread of accidents and
facilitate live maintenance.
2. The functional unit of the GCK drawer switchgear, with the
removal of the drawer, the unit components are completely separated
from the conductive vertical bus, and the electrical equipment can
be safely replaced and repaired. The main circuit plug and
auxiliary circuit plug of the functional unit have the
characteristics of firm insertion, uniform force, balanced
insertion and removal, etc., to ensure reliable connection.
3. The horizontal busbar of GCK type low voltage drawer switch
cabinet is installed on the top of the cabinet. It is a three-phase
five-wire system or a three-phase four-wire system. The
specifications are selected according to the calculated load or
specified by the user.
Working environment
1. The ambient air temperature should not be higher than +40℃, not
lower than -5℃, the average temperature within 24h should not be
higher than +35℃ if it exceeds, it needs to be derated and run
according to the actual situation;
2. Indoor use: the altitude of the place of use shall not exceed
2000m
3. The relative temperature of the surrounding air should not
exceed 50% when the temperature is +40℃. A larger relative
temperature is allowed at a lower temperature, such as 90% when the
temperature is +20℃. It should be considered that condensation may
occur accidentally due to temperature changes. The impact of
exposure;
4. When the device is installed, the inclination from the vertical
plane does not exceed 5°C, and the entire group of cabinets is
relatively flat (in accordance with the GBJ232-82 standard);
5. The device should be installed in a place where there is no
severe vibration and impact, and where the electrical components
are not corroded;
6. If the user has special requirements, it can be resolved through
consultation with the manufacturer.
