RA912F Return-type SF6 Gas Analyzer
Product Overview
The RA912F Return-type SF6 Gas Analyzer is a multi-functional, closed-loop SF6 gas comprehensive analysis platform designed for the operation and maintenance scenarios of high-voltage power equipment. This device can not only accurately measure the purity, humidity (dew point/PPM) of SF6 gas and key decomposition products (SO₂, CO, H₂S), but also innovatively integrates gas recovery and refilling functions, achieving a full – process closed – loop operation of “sampling – analysis – reinjection”. It truly realizes zero loss, zero emission, and zero pollution of SF6 gas, fully meeting the strict environmental protection and safety requirements of international standards such as IEC 60480 and IEC 62271 – 4.
Core Function Highlights
✅ One – key fully automatic measurement
After startup, the system automatically completes the whole process of sampling, analysis, and data locking. Return-type SF6 Gas Analyzer is easy to operate, and the results are stable and reliable, greatly reducing human errors.
✅ Closed – loop gas management: Recovery + Refilling
The SF6 gas after detection can be safely recovered to an external temporary storage container for subsequent purification treatment; or it can be directly refilled into the original sampling gas chamber to avoid gas waste. RA912F Return-type SF6 Gas Analyzer is especially suitable for the maintenance of high – value or sealed GIS equipment.
✅ Intelligent expert diagnosis system
RA912F Return-type SF6 Gas Analyzer has built – in judgment logics of multiple national standards (such as IEC, DL/T, IEEE), automatically evaluates whether the gas status meets the standards, and gives conclusions of “qualified/early warning/unqualified” to assist operation and maintenance personnel in making quick decisions.
✅ Modular design for convenient maintenance
Core modules such as sensors, pump units, and control units adopt a quick – disassembly structure, supporting on – site replacement or upgrade, significantly improving the equipment availability and service life.
✅ Large – capacity data management
The built – in storage space can save up to 10,000 detection records; it supports data export through a USB interface to generate standardized reports, seamlessly connecting with the enterprise CMMS or EHS management system.
✅ Human – oriented mobile design
RA912F Return-type SF6 Gas Analyzer adopts a high – strength trolley case structure with universal mute wheels, easily coping with complex on – site environments such as substations and switch stations. One person can efficiently complete long – distance movement and deployment.
Typical Application Scenarios
Maintenance and condition assessment of high – voltage/extra – high – voltage GIS (Gas Insulated Switchgear)
Routine maintenance and fault diagnosis of SF6 circuit breakers and GIL pipelines
Gas quality acceptance before the commissioning of new equipment
Verification of purification effects during the SF6 recycling process
Compliance testing and environmental audits of power companies and third – party testing institutions
