Sf6 Gas Leak Test Equipment is a portable instrument specifically designed for rapid positioning and qualitative detection of sulfur hexafluoride (SF6) gas leakage points.
1. Power system (core application areas)
This is the most important and widely used application scenario of Sf6 Gas Leak Test Equipment. SF6 gas is widely used in high-voltage and ultra-high voltage power equipment due to its excellent insulation and arc extinguishing performance.
GIS (Gas Insulated Composite Electrical) equipment leak detection: GIS is the core of the entire substation, sealing all high-voltage electrical components (circuit breakers, isolating switches, grounding switches, transformers, busbars, etc.) in a metal shell filled with SF6 gas. Regular leak testing of all welds, sealing surfaces, flange connections, inflation valves, observation windows, etc. in GIS is a crucial daily maintenance task.
SF6 circuit breaker leak detection: Whether it is a tank type circuit breaker or a pillar type circuit breaker, its arc extinguishing chamber and insulation pillar are filled with SF6 gas. Leak detector is used to detect leaks in its body, the sealing of the connecting rod of the operating mechanism, and the interface of the density relay.
SF6 Transformer (GIT) and Transformer Leak Detection: Some high-voltage transformers and current/voltage transformers also use SF6 gas as the insulation medium and require regular leak detection.
Leak detection of high-voltage cable distribution boxes and ring main units: In urban distribution networks, many gas filled cabinets (C-GIS) also use SF6 gas, and leak detection is required to ensure safe operation.
2. Equipment manufacturing and installation site
Factory inspection: On the power equipment production line, XP-1A Sf6 Gas Leak Test Equipment is used to conduct 100% sealing inspection on each finished or semi-finished product to ensure that there is no leakage in the factory products.
Installation and commissioning site: When reassembling after the construction of a new substation or major equipment repairs, it is necessary to conduct thorough leak testing on all reconnected sealing surfaces and chambers to ensure installation quality.
3. Laboratories and research institutions
Research and Teaching: In laboratories of universities and electric power research institutes, this equipment is used for related research projects, teaching demonstrations, and verification of new power equipment sealing technologies.
4. Other special occasions where SF6 gas is used
Although the vast majority of applications are in the power industry, theoretically any closed system that uses SF6 gas can use it for leak detection, such as:
Some types of accelerators or nuclear physics devices: SF6 is sometimes used as an insulating medium.
Nonferrous metal smelting: SF6 is used as a protective gas in the smelting process of metals such as magnesium and aluminum (although this scenario requires more quantity detection, it can also be used to detect pipeline leaks).
