To respond to the call of the country and realize carbon neutrality, our company has launched a green energy power switchgear called environmental protection cabinet for short, The equipment size is the same as that of the national grid standardization. BGHBN – 12 environment-friendly gas-insulated ring-network switchgear avoids the use of SF6 greenhouse gas compared with ordinary gas-filed cabinets. it has the characteristics of reasonable design, reliable power supply, compact structure, convenient installation, flexible operation, small size, high performance-price ratio, etc. This product applies to a three-phase AC 50Hz, rated voltage 12kV distribution system. it is especially suitable for receiving and distributing electric energy in small secondary distribution stations. switching stations, industrial and mining enterprises. urban residential areas. airports railways, tunnels, high-rise buildings, and other power systems.
Functional composite and integrated products
The gas-filled shell of the switchgear is made of high-quality 2.5mm thick stainless steel plate by laser welding to ensure the airtightness and reliability of the gas box, high mechanical strength, and good corrosion resistance. The protection grade of the gas-filled shel reaches lP67; The air box is equipped with an explosion-proof diaphragm, which can effectively prevent damage to people and equipment caused by high air pressure; Enclosing all conductive parts in the air box can not only avoid the influence of external environmental factors, but also improve the operation reliability, make it have the function of maintenance-free or less maintenanceand also meet the requirements of volume miniaturization.
The switch adopts a three-position isolation+grounding+vacuum arc extinguishing chamber, which is the most mature configuration mode at present, especially suitable for the current power grid operation and maintenance needs
Environmental protection and pollution-free
The insulation medium of the BGHBN-12 environment-friendly gas-insulated ring-network switch is zero-grade dry air (purchased) or 99.99% pure N2 by GB/T 8979-2008. The leakage of gas will not have any impact on the external environment, and no recovery treatment is required
Perfect mechanical interlocking
The operation panel of BGHBN-12 environment-friendly gas-insulated ring-network switchgear has a complete five-prevention mechanical interlocking function. All interlocking functions have been configured internally, Please operate according to the order of the operation instructions, which is very convenient to use.
Flexible expansion design
BGHBN-12 environment-friendly gas-insulated ring-network switchgear is of modular design, which can realize diversified unit combinations through various modules through special bus connectors, and meet the complex and diverse power distribution design schemes in various parts of China to the maximum extent.
