SF6 Gas Leak Detector (Qualitative)

Model: XHJL306  |  LCD Display SF6 Leakage Detector for Substation Equipment
Product Overview

The XHJL306 SF6 gas leak detector is a qualitative detection instrument for sulfur hexafluoride leakage. Its principle lies in the variable ionization level of the gas mixture exposed to high-frequency electromagnetic fields, which is directly correlated with the concentration of SF6 in the air; the SF6 concentration is then determined by measuring the ionization degree. Featuring a separate probe and main unit with a small vacuum pump, the instrument draws gas samples through a 4-meter pipe and displays the concentration on an LCD screen, automatically sounding an alarm when the measured value reaches the set threshold. It is an essential tool for routine leak surveys of GIS chambers, circuit breakers and gas-filled equipment in substations.

Applications & Target Audience: Engineered for fire and safety emergency response units, gas detection instrument integrators, industrial gas suppliers, power equipment online monitoring service providers and high-voltage test halls and type test stations that need to detect SF6 gas leakage from circuit breakers, GIS chambers and gas handling systems for equipment integrity, personnel safety and environmental compliance.

Performance Features
Direct LCD Concentration Display: The probe-mounted LCD shows the gas concentration in real time, allowing the operator to observe rising levels while scanning flanges and seals.
Automatic Audible Alarm: When the measured gas concentration is greater than or equal to the set value, the instrument automatically emits an alarm sound, enabling hands-free operation.
Split Probe with Vacuum Pump: The separate probe and main unit with a 0.5 liters/second vacuum pump and 4-meter pipe reach confined spaces and elevated connections easily.
Fast 3-Second Response: Rapid response time supports efficient scanning of large switchyards without missing transient leak signals.
Non-Toxic Safe Probe: The probe is non-toxic and does not produce toxic gases, protecting operators during prolonged leak surveys.
Wide 0.01-500ppm Range: Covers both fine leak tracing and gross leak confirmation in a single instrument.
Leak Detection Best Practices
Survey from Large to Small: First scan the whole chamber to identify the leaking zone, then narrow down to individual flanges, welds and valve connections for the exact leak point.
Prioritize High-Risk Joints: Focus on flanges, weld seams, pressure gauge connections and valve stems, which account for the majority of SF6 leaks.
Inspect After Gas Filling: Always perform a leak check after refilling or topping up SF6, as valve and connection disturbance is a common cause of new leaks.
Record and Trend Data: Log leak test results with the instrument's alarm readings to track recurring leak points and evaluate repair effectiveness.
Combine with Pressure Monitoring: Use leak detection together with density relay and pressure gauge readings to distinguish slow leaks from sudden losses.
FAQ
Q1: What is the XHJL306 SF6 gas leak detector used for?
It is used for qualitative detection of sulfur hexafluoride gas leakage from circuit breakers, GIS chambers, flanges, valves and pipe connections, with a measurement range of 0.01ppm to 500ppm.
Q2: How is the SF6 concentration indicated?
The concentration is shown on an LCD digital display, and the instrument automatically emits an audible alarm plus visual alarm signal when the measured concentration reaches the set value.
Q3: How does the split type design help on-site testing?
The separate probe and main unit, with a small vacuum pump and 4-meter pipe, allow the operator to reach confined spaces, elevated connections and hard-to-access areas while monitoring the display and controls.
Q4: How fast is the response time?
The response time is less than 3 seconds, enabling quick and efficient scanning of switchyards, chambers and gas connections during routine inspection.
Q5: What are the operating requirements?
The detector operates on AC 220V 50Hz at 7 to 40 degrees C with humidity up to 85%, and supports continuous operation for up to 4 hours.
