ZX SF6 Gas Recycling Devices: Technical Overview and Specifications

SF₆ gas is widely used in electrical power systems for its excellent insulation and arc-quenching properties. However, handling, recycling, and purifying SF₆ require specialized equipment to ensure safety, efficiency, and environmental compliance. The ZX series SF₆ gas recycling devices offer a range of solutions tailored for maintenance and recovery operations in substations and power facilities.

Key Features and Performance

The ZX series is designed to meet rigorous technical demands with the following core capabilities:

1.Recycling Performance: The system can recover SF₆ gas from initial pressures up to 0.8 MPa down to 50 kPa in under 2.5 hours per cubic meter of gas.

2.Refilling Efficiency: Refilling 1 m³ of SF₆ from 133 Pa to 0.8 MPa takes less than 0.8 hours.

3.Vacuum Capability: With an ultimate vacuum level of ≤10 Pa, the unit can evacuate 1 m³ of gas from 0.1 MPa to 133 Pa in under 1 hour.

4.Storage Capacity: Equipped with a storage tank capable of holding 50 kg of liquid SF₆, with a maximum storage pressure of 3.8 MPa.

5.Purification: Effectively reduces moisture content from ≤1000 ppm (volume) to ≤60 ppm (weight) and oil content to below 10 ppm (weight) in a single pass.

6.Leakage Rate: Annual leakage is limited to ≤1% of nominal storage capacity.

7.Operational Environment: Works reliably in temperatures from –10°C to 40°C, with sound levels under 75 dB(A).

8.Power Requirements: Operates on ≤5 kW, using a 3-phase 380V ±10%, 50 Hz power supply.

Models and Configurations

The ZX series includes several models to match different operational scales and throughput requirements:

Additionally, the series includes dedicated vacuum and refilling units:

1.ZX2015A: Equipped with a 54 m³/h Chinese vacuum pump, digital vacuum gauge, and auto-restart function.

2.ZX2018A: Features a German Leybold vacuum pump (65 m³/h), digital vacuum gauge, and automatic restart upon vacuum drop.

3.ZX2085A: Combines a 54 m³/h vacuum pump with a 70 L/S Roots pump for higher performance, also with auto-recovery function.

Design and Build

The device is compact, with dimensions of 1450 × 810 × 1200 mm and a weight of approximately 600 kg. Its robust construction ensures stable performance in demanding field conditions while maintaining user safety and operational simplicity.

Conclusion

The ZX SF₆ gas recycling series provides efficient, reliable, and scalable solutions for SF₆ gas handling. With flexible configurations and strong performance metrics, these units are well-suited for utility technicians and service teams involved in GIS maintenance, gas recovery, and emission control.
