SF6 Leak Detector/Gas Leak Detector/SF6 Gas Leak Detector - Testing Precautions and Features?

SF6 gas leak detectors are crucial tools for ensuring the safe operation of power equipment. Their core features and testing precautions are as follows:

I. Main Features

1. High Sensitivity: Utilizing advanced sensors (such as laser spectroscopy or high-frequency ionization technology), it can detect extremely small amounts of SF6 gas, with sensitivity typically reaching the ppm (parts per million) or even ppb (parts per billion) level, enabling early and accurate leak location.

2. Qualitative and Quantitative: Not only can it qualitatively locate leak sources through audible and visual alarms (alarm frequency changes with concentration), but it can also quantitatively detect leak concentrations and calculate annual leakage rates, providing data support for condition assessment.

3. Intelligent and Convenient: Equipped with automatic calibration, data recording, and background concentration subtraction functions. The probe has a fast response and a flexible extension rod, facilitating comprehensive inspection of complex structures in equipment such as GIS systems.

4. Safety and Environmental Protection: Effective detection of SF6 gas and its decomposition products (such as SO2 and H2S) helps prevent equipment failure and environmental pollution caused by leaks, enhancing personal and power grid safety.

II. Test Precautions

1. Safety and Environment: Testing must be conducted under well-ventilated conditions. Underground substations and other confined spaces require thorough ventilation beforehand. Operators should wear protective equipment and operate from an upwind location to prevent suffocation.

2. Instrument Preparation: After powering on, preheat until stable. If necessary, perform automatic zeroing or calibration in clean air to ensure accurate data reference.

3. Standardized Testing: The probe should move slowly and evenly (approximately 3-5 cm/s), focusing on scanning common leak points such as seals, welds, valves, and meters, maintaining a distance of 3-5 mm from the surface being tested. After hearing an alarm, briefly pause at that point to confirm.

4. Interference Elimination: Be aware of potential interfering gases in the environment (such as acetone and ethanol) to avoid false alarms. After testing, the instrument should be run in clean air until the reading reaches zero before being shut down. 5. Data Recording: Detailed recording of leak location, concentration, and other data provides a basis for subsequent maintenance. Regular professional calibration of the instrument ensures its sensitivity.

Correct use of this instrument is crucial for ensuring the safety of electrical equipment and environmental protection.

MS-403SF6 Gas Leak Detector

1. Capable of qualitative and quantitative detection of leaks in SF₆ electrical equipment.

2. Accurately locates the leak fault point in SF₆ gas electrical equipment.

3. Simultaneously displays multiple parameters including SF₆ concentration, temperature and humidity, battery indicator, time, and diaphragm pump status.

4. Employs non-dispersive infrared (NDIR) technology and a world-leading German-made sensor.

5. Fast testing speed; data stabilizes within 10 seconds, with excellent data repeatability.

6. Includes temperature and pressure compensation, perfectly compensating for gas concentration under different temperature and pressure environments.

7. SF₆ gas-only response; does not respond to any other gas, eliminating false alarms.

8. Non-contact gas measurement ensures that sensor poisoning will not occur at any concentration.

9. Sensor constant temperature chamber ensures that the sensor will not experience temperature drift under any ambient temperature. SF6 Gas Leak Detector, SF6 Leak Detector
