40.5GIS High Voltage Inflatable Switchgear

1Overview:

-40.5Series fully enclosedSF6 gas insulated ring main unit is a technology introduced by our company, which adopts modular design and features fixed and flexible expansionunify.Nxring-40.5The series of inflatable switchgear has the characteristics of compact structure, full insulation, long service life, maintenance free, small footprint, complete solutions, strong scalability, safety and environmental protection, and is not affected by the environment. It can be widely used in industrial, civil environmental networks and terminal power supply networks. Specially suitable for small secondary distribution stations, switch stations, industrial and mining enterprises, airports, railways, highways, subways, commercial areas, residential areas, wind power, optoelectronics and other fieldsThe switchgear has the characteristics of fully enclosed, maintenance free, small size, excellent performance, safety and reliability, long life, and maintenance free, and is highly welcomed by users.

IIProduct advantages:

1Application in high-altitude areas: SF6 gasFull insulation characteristicsThere is no need to consider the impact of pressure difference inside and outside the air box.

2Unit assembly: convenient for user expansion, scheme changes, and circuit switching.

3Distribution network automation application: It can work with all automation terminals on the market to easily achieve distribution network automation.

4Application in coastal areas: The institution is fully sealed and treated with long-term salt spray and anti-corrosion to ensure the safe operation of the equipment for a long time.

5Application of live replacement of PT cabinet: PT cabinet comes with isolation function, which can achieve online replacement.

6Application in strong sandstorm areas: institutional sealing, primary circuitandThe busbar is fully sealed, and the control circuit uses automotive specific sealing strips to ensure long-term safe operation in areas with strong sandstorms.

7.Free combination between units to achieve different solutions

IIIProduct Features:

Modular design, each unit module can be combined and expanded freely without the need for inflation or deflation, making it easy to combine solutions and design high-pressure metering, with a wide range of adaptability.SF6 fully insulated circuit breaker inlet and outlet cabinets (vacuum arc extinguishing), load switch inlet and outlet cabinets, bus tie cabinets, metering cabinets, load switch fuse combination electrical cabinets, and TV cabinets (with or without switches) can be compactly combined into single unit, two unit, three unit, four unit, etc., providing broad application prospects for SF6 fully insulated ring main units or multi circuit distribution cabinets.

The cabinet adopts an armored structure, and there are metal partitions between the busbar room and the switch room, as well as between the switch cabinet and the cable room. The primary protection level of the fully insulated structure can reachIP67。

A load switch with three workstations welded on the punchSF6 gas is sealed in a stainless steel shell, with excellent airtightness and low gas consumption, ensuring no gas leakage for 30 years and meeting environmental requirements. It is suitable for indoor or outdoor use with metal or non-metal shells, or for use in underground or semi underground substations.

The operating mechanism is made of corrosion-resistant metal, and the bearings of the rotating parts are self-lubricating designed. The product is not affected by the environment, does not require regular maintenance, and is easy to connect with the outside world. This makes the operating power small, the reliability high, and the service life longer.

The expansion busbar adopts plug-in silicone connectors, fully insulated and shielded to ensure reliable conductivity and is not affected by the surrounding environment. The combination connection and expansion are convenient, making it easy for users or substations to undergo capacity expansion and renovation in the future.

4Environmental conditions for use:

Air temperature: Maximum temperature:+40°，Temperature: -20 ° C;

Temperature: Monthly average temperature95%, daily average temperature 90%,

Altitude: Maximum installation height:2500 meters;(Customization required for higher altitudes)

No flammable, explosive, serious pollution, chemical corrosion, or severe vibration.

5Main technical parameters:

(Note)1) Depends on the rated current value of the fuse

VICabinet structure: Inflatable compartment adopts3-5MM thick stainless steel plate, processed by CNC machine tool and welded by welding robot, with less welding deformation and good air tightness. The remaining compartments are made of high-quality cold-rolled steel plates, welded by CNC bending, with high precision and good strength; Each functional unit is an independent module, making assembly extremely convenient. Each sealed compartment of the cabinet is equipped with independent pressure relief channels to maximize personal safety and equipment operation.
