Functional composite and integrated products
The inflatable casing of the switchgear is made of high-quality 2.5mm thick stainless steel plate through laser welding, ensuring the sealing reliability of the air box, high mechanical strength, good corrosion resistance, and the protection level of the inflatable casing reaches IP67; The air box is equipped with explosion-proof diaphragm, which can effectively prevent damage to people and equipment caused by high air pressure; Enclosing all conductive components in an air box can not only avoid the influence of external environmental factors, but also improve operational reliability, enabling it to have maintenance free (or minimal) functions, and also meet the requirements of volume miniaturization.
The switch adopts a three station (isolation+grounding)+vacuum arc extinguishing chamber structure, which is currently the most mature configuration method and particularly suitable for the current operation and maintenance needs of the power grid.
Environmental protection and pollution-free
The insulation medium of LPHBN-12 energy-saving and environmentally friendly fully insulated ring main unit is zero level dry air (purchased externally) or 99.99% pure N2 in accordance with GB/T8979-2008. Gas leakage will not have any impact on the external environment and does not require any recycling treatment.
Complete mechanical chain
The operation panel of LPHBN-12 energy-saving and environmentally friendly fully insulated ring main unit has a complete five proof mechanical interlocking function, and all interlocking functions are configured internally. Please follow the operation instructions in the order of operation, which is very convenient to use.
Flexible and scalable design
The LPHBN-12 energy-saving and environmentally friendly fully insulated ring main unit is designed in a modular manner, which can connect various modules through dedicated bus connectors to achieve diversified unit combinations and maximize the satisfaction of complex and diverse distribution design schemes in various parts of China
