RF-051 Compact SF6 Recovery Unit

Why does the power system need a professional SF6 recovery unit?

As the core insulating medium of power equipment (such as circuit breakers and GIS equipment), the processing quality of SF6 gas directly affects the equipment lifespan and grid safety:

• The traditional decentralized processing (separate operations of vacuuming, recovery, and refilling) has low efficiency, and each maintenance takes more than 4 hours;
• The recovery rate of non – professional equipment is less than 80%, resulting in waste of SF6 gas (high cost) and environmental pollution (meeting the environmental protection requirements of the Kyoto Protocol);
• Unfiltered impurities (moisture, solid particles) can cause equipment insulation breakdown and increase the risk of power outage failures.

The RF – 051 small – sized SF6 recovery unit addresses the above pain points by integrating multiple core functions and has become the preferred equipment for SF6 gas processing in the power system.

RF – 051 SF6 Recovery Unit: Core Functions and Scene Adaptation

1. Multi – scene vacuuming: Real – time monitoring, precise control

Technical advantage: Equipped with a PLC intelligent operation screen, the vacuum degree change is displayed in real – time (with an accuracy of 0.1Pa), avoiding the problem of non – compliant vacuum degree caused by “blind vacuuming” of traditional equipment;

Applicable scenarios: Vacuuming before the maintenance of the SF6 switch gas chamber, pre – treatment of external pressure vessels (such as cylinders). The single – time vacuuming efficiency is 30% higher than the industry average.

2. Flexible gas recovery: Dual – storage mode, adapting to different needs

Dual – path selection: It can be recovered to the equipment’s built – in gas storage tank (with optional capacity) or directly connected to an external cylinder, solving the differential needs of “small – batch immediate recovery” and “large – batch storage”;

Negative – pressure recovery technology: Breaking through the limitations of traditional positive – pressure recovery, the recovery rate is increased to over 95%, reducing SF6 gas emissions and meeting the environmental protection maintenance standards of the power industry.

3. High – efficiency gas refilling: Multi – mode switching, adapting to equipment types

Direct – filling mode: Supports regulated pressure output (0.1 – 0.8MPa), adapting to low – pressure SF6 equipment (such as small – sized circuit breakers);
Pressure – filling mode: Includes gas pressure – filling and liquid pressure – filling methods. The refilling time for high – voltage equipment (such as GIS combined electrical appliances) is shortened to half that of traditional equipment;

Auxiliary system: An independent storage tank + gas heating system solves the problem of refilling blockage caused by SF6 gas liquefaction in low – temperature environments. It can still operate stably in an environment of – 20℃.

4. Rapid liquid filling: Completing the filling of a 40L cylinder in 5 – 8 minutes

Efficiency data: It only takes 5 – 8 minutes to fill a 40L cylinder with 50kg of SF6. Compared with the industry – average filling speed of 15 minutes, the efficiency is increased by over 40%;

Safety guarantee: The pressure is automatically monitored during the filling process, and the machine stops automatically when over – pressured, avoiding the risk of over – filling the cylinder.

Core Competitive Advantages of the RF – 051 SF6 Recovery Unit

1. Deep impurity filtration: Ensuring gas purity and extending equipment lifespan

It has a built – in three – stage filtration system (precision filter element + molecular sieve + activated carbon), which can filter SF6 gas for:

• Moisture (dew point ≤ – 60℃ after filtration);
• Decomposition products (such as SO2, HF);
• Solid particles (with an accuracy of 0.1μm). The gas purity after treatment meets the GB/T 12022 – 2014 standard, avoiding equipment insulation failures caused by impurities.

2. Anti – oil – return and safety design: Reducing maintenance risks

The vacuum pump is equipped with a one – way anti – oil – return valve, completely eliminating the problem of oil back – flow and pollution of SF6 gas when the machine stops, reducing equipment maintenance costs;

Semi – enclosed protective structure: The dust – proof and waterproof level reaches IP54, adapting to complex environments such as outdoor substations, dusty, and high – humidity environments. The equipment service life is extended to more than 8 years (the industry average is 5 years).

3. Global environmental adaptation: Multiple refrigeration methods available

In view of the climatic conditions in different regions, 3 refrigeration solutions are provided:

• Air – cooled type: Adapting to temperate regions (-5℃~40℃);
• Water – cooled type: Adapting to high – temperature regions (40℃~50℃);
• Low – temperature enhanced type: Adapting to frigid regions (-30℃~ – 5℃), ensuring that the power systems around the world can be used efficiently.

4. Modular design: Convenient maintenance and cost optimization

The core components (vacuum pump, filter, storage tank) can be modularly disassembled. There is no need to disassemble the whole machine during maintenance. The single – time maintenance time is shortened to within 2 hours (traditional equipment requires 4 – 6 hours);

Simple operation: With a Chinese/English bilingual operation interface, operators can get started after 1 – hour training, reducing labor training costs.

Applicable Scenarios of the RF – 051 SF6 Recovery Unit

Substations of power grid companies: Routine maintenance and gas replacement of SF6 circuit breakers and GIS equipment;

Power maintenance units: Outdoor/on – site emergency SF6 gas treatment (such as gas recovery from faulty equipment);

Equipment manufacturing enterprises: Vacuuming and gas filling before the factory of SF6 electrical equipment;

New energy power stations (wind power, photovoltaic): Lightweight maintenance of box – type SF6 equipment (the equipment weighs only 300kg and is easy to carry).os.
