Product Description
1.GeneralGCK low voltage withdrawable type switchgear is widely used in power plant and metallurgical, petroleum chemical, textile industries port and high-rise buildings and hotels; GCK (three phases and four or five lines; voltage: 380V, 660V; frequency: 50HZ; rated current: 5000A and below) can be used as the power distribution and motor centralized control in power generating and supplying system.GCK passed all the tests and gained CCC certificate. The advanced design of GCK meets the following standards: GB7251.1 "Low Voltage Switchgear" and IEC61439.1 "Low Voltage Whole Set Switching and Controlling Equipment".2.Structure FeaturesFunction Unit (Drawer)The height module of drawer unit is 200mm, There are five series of series of function unit: 0.5unit, 1unit, 1.5units, 2units, 3units. The rated current of the unit circuit is 630A and below.Each MCC cabinet can be installed with 9of 1 unit drawer and 18 of 0.5 unit drawer at most.Operating mechanism and the drawer are interlocked, When the switch is in closing position, the drawer can not be drawer out.The lock of operation mechanism can lock the drawer in breaking or closing position for safety maintenance.The plugs of main circuit inlet and outlet lines and auxiliary circuit secondary lines are the back of the function unit.Function unit is separated by metal plate.The drawer unit uses rotating feed mechanism and has three functional positions for easy and reliable operations.The draw-in and draw-out function are achieved through the positioning movement in helical track. During the processes of draw-in and draw-out, the three functional positions are indicated and mechanical interlocking works. The drawer is equipped with micro switch. The electrical interlocking happens when it is in test position.The frame is assembled by C type material, and the matched components are provided by the company to make sure the accuracy and quality of the frame.The dimensions of components, holes and intervals are modulated (module E=20mm, the same below)Inner structures are processed through zinc plating.The cover of the roof is removable. The flying rings at the four corners at the top of cabinet are forcraning, loading and transporting.The frame is separated into three independent compartments: busbar compartment, function unit compartment and cable compartment to prevent accident to spread.3.Working ConditionsAmbient temperature: -5ºC~+40ºC and the average temperature in 24h must below 35ºC.Humidity: ≤50% at the highest ambient temperature +40ºC, lower temperature with higher humidity, such as ≤90% at 20ºC, mild condensation occasionally happens for the variations of the temperature.It is applicable in the place with clean air and without corrosive and explosive gases and without the non-conductive and de-isolation dusts.The inclination to the vertical plane is not more than 5° and the switchgear should be operated in the conditions without obvious shaking and violet vibration.Altitude:≤2000mTemperature for Transferring and Storing: -25ºC-+55ºC and short-term temperature in 24h must below 70ºC.Other special requirements need to be discussed when ordering.4.SpecificationsRated Insulation Voltage | 660V/1000V |
