(Sulfur Hexafluoride) High-precision instrument for sealing performance of gas-insulated equipment such as GIS, SF6 circuit breakers, and instrument transformers
Gas Quantitative Leak Detector is a high-precision instrument specifically used in the power industry to detect the sealing performance of SF6 (sulfur hexafluoride) gas-insulated equipment (such as GIS, SF6 circuit breakers, and instrument transformers). In previous discussions, we covered testing of transformers and cables, while SF6 gas equipment is another core component of high-voltage power grids (especially at 110kV and above). SF6 gas has extremely high insulation strength and arc-extinguishing capability, but its leakage can lead to insulation degradation and equipment failure. Moreover, SF6 is a potent greenhouse gas (with a greenhouse effect 23,900 times that of CO2), so environmental regulations impose extremely strict controls on its leakage. The following is an in-depth analysis of this equipment: 1. Core Functions: From "Qualitative" to "Quantitative" Qualitative Leak Detection: Only answers "Is there a leak?" (e.g., using handheld halogen leak detectors, soap water method). It can only locate the approximate position of the leak, not the amount. Quantitative Leak Detection: Answers "How much is leaking?" (Leak Rate). Unit: Usually in
