GCK type low-voltage drawer type switch cabinet frame main material is made of open-type steel, the use of Angle plate positioning, bolted welded structure, parts molding size, opening size and equipment spacing implement modular. The cabinet is divided into three separate sections: bus bar room, functional unit room and cable room, which can effectively prevent accident diffusion and facilitate on-line maintenance;
The functional unit of GCK type low-voltage drawer switch cabinet, with the drawer removed, the unit device is 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 solid plug, uniform force and balanced plug and pull to ensure reliable connection. The unit compartment is separated by metal plate, and the valve in the compartment can be automatically closed with the drawer pulled out to ensure that the human body can not touch the charged vertical bus bar to ensure safety;
The horizontal bus bar of GCK type low-voltage drawer switch cabinet is installed on the top of the cabinet, which is three-phase five-wire system or three-phase four-wire system. The specifications are selected according to the calculated load or specified by the user. The vertical bus bar is closed with halogen-free non-toxic and flame-retardant engineering plastic shell.
Altitude does not exceed 2000m. The ambient air temperature is not higher than +40℃, and the average temperature within 24 hours is not higher than +35℃, and the ambient air temperature is not lower than -5℃.
Atmospheric conditions: The air is clean, the relative humidity does not exceed 50% when the temperature is +40 ° C, and the relative humidity is allowed to be higher when the temperature is low.
No fire, explosion danger, serious pollution, chemical corrosion and violent vibration of the place, pollution level III, creepage distance ≥2.5cm/KV, and vertical tilt does not exceed 5°.
The control center is suitable for the transport and storage process at the following temperature, -25℃~+55℃, and does not exceed +70℃ in a short time.
GCK type low-voltage drawer switchgear is used in power plants, substations, petrochemical, metallurgical rolling, light industrial textile and other factories and mining enterprises and residential areas, high-rise buildings and other places, as AC 50~60Hz, rated working voltage AC 660V and below the power system of the power distribution equipment for power conversion, distribution and control.
