GCS LV with drawable switchgear is developed according to the requirements from industry competent department, numerous electric users and design unit by original state mechanical department, united design group of power department. It conforms to national conditions and with higher technical performance index, and adapts the demands for power market development and able to compete with available imported products.
The device passed the authentication jointly presided by two departments in July 1996 in Shanghai. It obtains the recognition and affirmation from manufacturing unit and power consumer construction.
The device is applicable to the distribution system of power station, petroleum, chemical engineering, metallurgy, weaving and tall building industries etc. In the places with high automaticity and need computer to joint, such as large-scalepower station and petrochemical industry system etc, it is the low voltage complete distribution device used in the generating and power supply system with three-phase AC50(60)Hz, rated working voltage 380V, rated current 4000A and below for distribution, motor central control and reactive power compensation. The device accords with standards IEC439-1 and GB7251.1.
1.Main framework adopts 8MF bar steel. Both sides of bar steel is installed with φ9.2mm mounting hole with modulus 20mm and 100mm. Inner installation is flexible and easy.
2.Two types of assembly form design for main framework, full assembly structure and partial (side frame and cross rail) welding structure for user selection.
3.Each function compartment of device is separated mutually. The compartments are divided into function unit compartment, bus bar compartment and cable compartment.Each one has relative independent function.
4.Horizontal bus bar adopts cabinet back level placed array pattern for enhancing the capacity of resisting electron dynamic force for bus bar. It is the basic measure for obtaining high short circuit strength capacity for main circuit.
5.Cable compartment design makes cabIe outlet and inlet up and down convenient.
Use environmental conditions
1. Ambient temperature:-5ºC~+40ºC;
2.Altitude: ≤2000m;
3. Relative humidity:daily≤95%, monthly≤90%;
4. Seismic intensity:≤Ms8;
5. Vapor pressure: daily≤2.2kPa, monthly≤1.8kPa.
6. Ambient environment: the installation site should be free of fire, explosive danger,serious pollution, chemical corrosion or severe vibration.
