SF6 Gas Infrared Imaging Leak Detection Equipment

MOEORW-WJL2 split-type SF6 quantitative leak detector consists of a main control console and a separated handheld detection gun, adopting NDIR dual-wavelength non-dispersive infrared measurement technology. The system excludes radioactive materials and requires no carrier gas supply, with an internal sampling pump realizing 1-second ultra-fast gas response. The equipment is unaffected by ambient humidity and background pollutant gases, supporting trace SF6 detection down to 1 ppmv. The dual-display system separates main console and handheld gun operation interfaces, with built-in printing and data storage modules to generate formal test reports, suitable for long-duration quantitative leakage detection of high-capacity power SF6 gas-insulated equipment.

Hardware & Structural Design
1.Split split-body structure (main console + separate detection gun) for long-distance pipeline detection;
2.Aviation plug connection between console and probe for stable signal transmission;
3.Independent charging interface and power switch layout on main console for centralized power management;
4.Particle filter matched on detection gun front-end to intercept particulate contaminants;
5.No wearing consumable parts, low long-term equipment operation cost.
 

Performance Advantages
1.Zero cross-interference from humidity and background impurity gases, stable measurement in complex site environments;
2.1-second ultra-fast gas intake response to capture transient leakage signals;
3.Detection limit down to 1 ppmv to realize trace SF6 leakage quantitative analysis;
4.No radioactive raw materials, unrestricted storage and cross-regional transportation;
5.Ultra-low maintenance frequency, only one comprehensive maintenance every 5 years under standard working conditions.
 

Practical Application Values
1.Independent SF6 alarm value and calibration value adjustable module for customized testing standards;
2.Selective single-record deletion and full-data formatting functions with irreversible operation reminder;
3.Handheld gun touch screen sliding navigation for one-switch access to measurement, record and parameter setting pages;
4.Built-in timestamp editing function to calibrate system time for accurate record filing;
5.Standard sealed bag sampling leakage rate calculation formula matched for quantitative leakage volume conversion.

1.Quantitative leakage detection of large-scale GIS combined electrical equipment air chambers;
2.Routine inspection and acceptance testing of SF6 circuit breakers and inflatable ring main units;
3.Power plant high-voltage SF6 insulated equipment long-term monitoring;
4.Factory ex-factory leakage testing of SF6 gas-filled electrical products.

1.Prevent violent vibration and impact during transportation and on-site testing to protect internal pump and sensor components;
2.Inspect battery residual power before each use; fully charge the lithium battery for long-term idle storage;
3.Standard calibration cycle: annual full calibration; shorten cycle according to actual gas pollution degree;
4.Full charging takes 2–3 hours; charging adapter red light indicates charging, yellow light represents full charge with built-in overcharge protection circuit;
5.Regularly inspect the gas pipeline between main console and detection gun for air leakage.
