XP-1A Sulfur Hexafluoride (SF6) Qualitative Leak Detector

XP-1A Sulfur Hexafluoride (SF6) Qualitative Leak Detector

Application Areas: GIS and SF₆ gas insulated circuit breaker leakage detection in the power industry

The XP-1A SF6 Qualitative Leak Detector is the culmination of more than 30 years of leak detector manufacturing experience. As the most stable and sensitive negative corona leak detector ever made, the heart of this device is an advanced microprocessor. Its digital signal processing allows for better control of the circuit and sensor head signals than ever before. In addition, the number of components used in the circuit is reduced by approximately 40%, thereby improving reliability and performance. The microprocessor monitors the sensor head and battery voltage values ​​in real time up to 4000 times per second, and can promptly compensate for even the slightest change in signal pulsation. This makes the instrument a stable and reliable detection tool for almost all environmental applications.

The XP-1A SF6 Qualitative Leak Detector has been designed with many user-friendly features. The seven levels of sensitivity are freely set, increasing the sensitivity of the instrument by 64 times from level 1 to level 7; the unique three-color LED displays the progressive and wide-range leakage size indication; notifies the sensitivity level; and provides an actual voltage indication of the battery charge. The touch keyboard controls all functions; the novel shell design allows users to hold it tightly and operate it easily; and it is equipped with intuitive indicators for visual inspection during use.

Key Points Of Operation And Maintenance

Steps Of Use

• Preheating after power-on: Preheat to a stable state as required by the manual.
• Calibration zeroing: Calibrate in a clean environment without SF₆ gas to avoid background interference.
• Detection scanning: Move the probe close to the suspected leak point (usually ≤5cm away), move slowly, and observe the alarm prompt.
• Location mark: After the alarm is found, gradually narrow the scope and determine the specific leak location (such as valve interface, sealing ring, etc.).

Maintenance Precautions

• Clean the probe regularly: Avoid dust and oil from clogging the sensor.
• Calibration cycle: It is recommended to calibrate at least once a year to ensure sensitivity.
• Storage environment: Moisture-proof, sun-proof, away from corrosive gases.

Selection Reference Factors

• Sensitivity requirements: Select the detection accuracy (such as 1ppm, 5ppm level) according to the risk level of equipment leakage.
• Use environment: Outdoor detection needs to consider anti-interference ability (such as windproof design); narrow space needs to be equipped with an extended probe.
• Additional functions: Whether it has intelligent functions such as data storage, Bluetooth transmission, and GPS positioning.
• Brand and certification: give priority to brands that have passed ISO standard certification.

Safety Tips

• Although SF₆ gas is non-toxic, it will displace oxygen at high concentrations, leading to the risk of suffocation. Ensure good ventilation during testing.
• Avoid using in strong electromagnetic fields and high temperature (>50℃) environments, which may affect the performance of the instrument.
• If a leak is found after testing, ventilate in time and contact professionals for treatment. It is strictly forbidden to dismantle high-voltage equipment by yourself.
