Advantages
Strict Global Standard Compliance
Fully designed and calibrated in accordance with IEC 60480 (Guidelines for the handling and disposal of SF6), IEC 62271-203, and GB/T 8905 standards, process data is globally recognized, meeting the compliance requirements of power utilities, international projects, and environmental regulations.
Ultra-High Vacuum Performance & Efficiency
55L/s high-speed dual-stage vacuum pump delivers ultimate vacuum down to ≤0.1Pa, far exceeding the industry standard 1Pa requirement. It ensures complete removal of moisture, air, and impurities from SF6 equipment gas chambers, preventing insulation degradation and equipment failure caused by residual gas and moisture.
Precision Filling for Long-Term Equipment Reliability
Closed-loop mass flow metering with ±1% filling accuracy, combined with automatic temperature and pressure compensation, ensures precise control of SF6 gas density in the equipment. This eliminates the risk of over-filling or under-filling, guaranteeing optimal insulation performance and long-term reliable operation of SF6 assets.
Fully Automated Operation to Reduce Human Error
One-click fully automatic workflow covers the entire process from pre-vacuum detection to post-filling pressure verification, eliminating manual operation steps and human error. Even non-specialist operators can complete standardized, compliant SF6 gas handling with minimal training.
Zero-Leak Environmental Protection Design
Fully enclosed gas circuit with metal sealed connections minimizes SF6 gas emissions, supporting global carbon reduction goals and compliance with SF6 environmental regulations. The system’s closed-loop design also eliminates operator exposure to SF6 gas, ensuring workplace safety.
Field-Proven Ruggedness & Reliability
Mobile trolley structure with industrial-grade shockproof components ensures stable performance in harsh outdoor and industrial environments. The system requires minimal maintenance, with long service life of the vacuum pump and core components, delivering low total cost of ownership for users.
FAQ
Q: What international standards does the GSH-V/D-55 comply with?
A: The system is fully designed and calibrated in accordance with IEC 60480 (Guidelines for the handling and disposal of SF6), IEC 62271-203, and GB/T 8905 standards for SF6 gas handling, with globally recognized process data and compliance.
Q: What is the ultimate vacuum degree of this machine?
A: The ultimate vacuum degree is ≤0.1Pa, which fully meets the strict vacuum requirements of HV SF6 equipment commissioning and maintenance, ensuring complete removal of air, moisture, and impurities from the gas chamber.
Q: What is the filling accuracy, and can it compensate for environmental changes?
A: The filling accuracy is ≤±1% full scale, with built-in automatic temperature and pressure compensation function, eliminating filling errors caused by on-site temperature and pressure changes, ensuring accurate SF6 gas density control.
Q: What types of SF6 equipment is this machine suitable for?
A: It is suitable for all SF6-insulated high-voltage equipment, including GIS, SF6 circuit breakers, load switches, ring main units, current/voltage transformers, and gas-insulated power transformers.
