GCS low voltage extractable switchgear
GCS low voltage pull out switchgear
Summary of products
GCS low-voltage switchgear is the latest type of low-voltage distribution cabinet developed by the Ministry of Electric Power Industry and the Ministry of Machinery Industry. The maximum capacity of bus can reach 5000A. It is stable, safe and reliable.
Characteristics of products
The main frame of_device is made of 8MF steel frame with two types of structure: assembling and partial welding, which has high mechanical strength. Both sides of section steel have modulus of 20mm and
The installation holes of 100mm 9.2mm are flexible and convenient to install inside.
The function rooms are strictly separated, and the functions of each unit are relatively independent, and the protection level is high.
The drawer of the functional unit is small and compact and can be conveniently interchanged.
_Drawer panels have obvious marks for the position of bench and sub-test drawer, and drawers are equipped with mechanical interlocking devices.
Feeder cabinet and motor control cabinet have special cables compartment. The cable connection between function unit and cables room is realized by switching parts or switching copper bars, that is to say, the electricity is improved.
The reliability of cable has greatly facilitating the installation and maintenance of cables.
Features of the device:
A. Increase the heat capacity of the adapter, greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the adapter, cable head and spacer plate.
B. The separation between functional units and compartments is clear and reliable, and the fault of one unit does not affect the work of other units, so that the fault is limited to the minimum range.
C. The parallel arrangement of generators makes the device have good dynamic and thermal stability and can withstand the impact of 80/176KA short-circuit current.
D, MCC cabinet single cabinet circuit number up to 22 times, fully consider the large single capacity power plant, plant and mining system waiting for the industry automation door (machine) group needs.
E. The connection between the device and the external cable is completed in the cable compartment. The cable can be in and out of the compartment. The zero-sequence current transformer is arranged in the cable compartment to facilitate installation and maintenance.
In the same power distribution system, the short-circuit current can be limited by matching the current-limiting reactor, the bus current can be stabilized at a certain value, and the short-circuit of components can be partly reduced.
G. Drawer units have a sufficient number of secondary connectors (32 pairs for units 1 and above, 20 pairs for units 1/2). It can meet the requirement of the number of docking points in the computer interface and automatic control loop.
Conditions of use
_ambient air temperature is not higher than + 40, not lower than - 5, the average temperature within 24 hours should not be greater than + 35.
Indoor installation and use. The altitude of the site should not exceed 2000m.
_Relative humidity of ambient air does not exceed 50% at the highest temperature of +40 C, and greater relative humidity is allowed at lower temperatures, such as 90% at +20 C. Consideration should be given to the effect of accidental condensation due to temperature changes.
Equipment installation is not more than 5 degrees of inclination with vertical surface.
Equipment shall be installed where there is no violent vibration or shock and where there is insufficient corrosion of electrical components.
If there are special requirements, it can be negotiated with the manufacturer.
