Description
The GSH-R-5 is a cost-effective, field-optimized portable SF₆ gas recovery and purification unitexclusively designed for SF₆ gas handling in 10kV-35kV distribution equipment such as ring main units, SF₆ circuit breakers and instrument transformers. It fully complies with DL/T 662.1-2021, IEC 60480:2019 and GB/T 8905-2012 standards, adopting an oil-free high-pressure compressor, single-stage rotary vane vacuum pump and 4-stage deep purification system to achieve efficient recovery and purification of SF₆ gas.
The unit features an integrated hand-push mobiledesign weighing only 80kg, supporting single-person operation and easy movement in narrow spaces such as distribution rooms and cable trenches. It uses AC220V single-phase power supply, which is widely available in distribution networks, eliminating the need for three-phase power. Equipped with high-precision pressure gauges and vacuum gauges, it supports both semi-automatic and manual operation modes. The 4-stage purification system can remove moisture, oil, dust and other impurities from recovered SF₆ gas, making it meet the new gas standard and can be directly reused. With comprehensive safety interlock protection and reliable performance, it is the ideal solution for SF₆ gas management in distribution power systems.

FAQ
Q: Can the recovered SF₆ gas be directly reused?
A: Yes. The 4-stage deep purification system can effectively remove moisture, oil, dust and other impurities from recovered SF₆ gas. After purification, the gas quality meets GB/T 8905-2012 new gas standard and can be directly refilled into equipment for use.
Q: Does it require three-phase power supply?
A: No. GSH-R-5 uses AC220V single-phase power supply, which is widely available in distribution rooms, residential areas and industrial sites, greatly improving on-site operation convenience.
Q: What is the maximum capacity of ring main unit that this unit can handle?
A: It can handle 10kV-35kV ring main unit single gas chambers up to 0.1m³, which covers the vast majority of mainstream ring main unit models on the market.
Q: What is the maintenance cycle of the unit?
A: The adsorbent in the purification system should be replaced every 2 years or after processing 1000kg of SF₆ gas. The vacuum pump oil should be changed every 6 months. Annual calibration of pressure gauges and vacuum gauges is recommended.
