Product Details

    The GWWG-III High-Precision SF6 Gas Quantitative Leak Detector is meticulously designed based on feedback from a wide range of users, combined with the actual conditions of China's power system. In addition to overcoming the shortcomings of foreign products and absorbing their advantages, this instrument features high sensitivity, good stability, fast response speed, simple operation, and a large detection range. It can quickly and accurately perform qualitative and quantitative detection of leakage points and annual leakage rates in SF6 circuit breakers and GIS. The instrument is highly suitable for use by power supply departments, installation and maintenance units, and electric power test research institutes.

    2. The instrument is lightweight and compact, capable of detecting higher leakage points with a large detection range.

    3. High sensitivity: Optimized design is adopted in the high circuit, while reducing noise and electromagnetic interference, thereby improving sensitivity.

    4. Wide measurement range with multiple gear switching: The instrument can detect SF6 leakage within the leakage rate range of SF6 switchgear, with multiple gear switching options, and provides standard curves for each gear, enabling both quantitative and qualitative leak detection.

    5. High accuracy: The instrument uses advanced calibration methods to provide high-accuracy standard curves, improving the credibility of SF6 leak detection results and the precision of quantitative leak detection.

    6. Intuitive display with audible and visual alarm: The instrument uses an indicating meter for display, providing a simple and intuitive effect. When SF6 gas is present, the instrument emits an audible and visual alarm.

    7. Fast response and short recovery time: A new circuit structure is adopted to speed up the instrument's response and shorten recovery time, greatly facilitating on-site detection.

    8. Built-in self-diagnostic function: This instrument has the ability to monitor its own working status.

    9. Attractive appearance: All button switches on the panel are indicated by indicator lights.

    10. Long usage time: The usage time can reach 3 hours, making it very suitable for field use, SF6 high-voltage switchgear factories, and research institutes.

    11. Strong anti-interference capability: The instrument is fully shielded, eliminating external and internal interference.

    12. High stability: The instrument has high power supply voltage stability, low temperature, low heat loss, and good thermal stability. During the instrument's usage time, zero drift and span drift are small.

    13. Good repeatability: The instrument shows good repeatability in multiple measurements.

    14. High reliability: The instrument has a reasonable circuit structure; imported components are used and strictly screened, and it is also equipped with overcurrent and short-circuit protection.
