GCK low voltage distribution cabinet
GCK low-voltage power distribution cabinet (hereinafter referred to as switch cabinet) is used in AC 690V and below. The rated frequency is 50~60Hz. It is used for power receiving, feeding, reactive power compensation, energy metering, lighting and motor centralized control. This product meets; national standard GB7251 "low-voltage switchgear" ZBK36001 "low-voltage withdrawable switchgear".
Conditions of Use
The ambient air temperature is not higher than +40 C. Not lower than 10 c. and its average temperature is not higher than +35 c within 24 hours.
The relative humidity of the surrounding air does not exceed 50% at a maximum temperature of +40 ° C. A relatively large relative humidity is allowed at a lower temperature. For example, 90% at +20 C. However, it may be considered that the temperature may change accidentally. Produces moderate condensation.
The indoor use altitude does not exceed 2000m.
It should be installed in a place where there is no severe vibration and impact and no corrosive substances, if the above conditions of use are exceeded. It should be resolved by the user and the manufacturer.
■GCK's external dimensions are always standard size: 2200mm in height. The width includes 600800 and 1000mm. The depth includes 800mm and 1o0mm. The cabinets are neatly arranged and compact. The floor space is small.
■ The horizontal busbar is installed on the top of the GcK cabinet. The front part of the drawer cabinet is the cable compartment in the middle of the electrical compartment. The rear part of the assembly is the busbar compartment. The vertical pluggable busbar is laid. In each drawer rear panel is equipped with a main circuit connector socket for a total of 2 pay and 10A auxiliary circuit contacts 620 for a mating plug 1 pay.
■ Due to the reasonable combination method, the total capacity of the 600mm wide capacitor cabinet can reach 160Kvar.800mm wide and the total capacity of the capacitor cabinet can reach 240Kvar. Make full use of the effective space in the cabinet.
■ Adopting more advanced design and process drawer unit operation is flexible and interchangeable.
■Function unit chamber height is divided into 200.400.600mm three kinds of cumulative effective installation unit height 1800mm. 1/2 function unit can be processed as required. The unit cabinet can hold up to 18 12 unit drawers or 9 one unit drawers.
■Each functional unit has perfect and reliable operation mechanism, obvious switch separation, accurate position limit of drawer position mark and limited measures to prevent misoperation, and safe and reliable operation.
