Optical Gas Cameras | Solutions for SF6 Gas Leak Detection Applications
In recent years, with the continuous progress and development of modern detection technology, there have been more and more optical imaging techniques applied to SF6 gas leakage detection. Infrared imaging leakage detection technology as a kind of charged detection technology for SF6 gas leakage detection of high-voltage electrical equipment has been more and more researched and applied.
SF6 gas is a colorless, odorless, inert gas with a density heavier than air and not easily mixed with air, and is not toxic to humans. However, under the action of high-voltage arc or at high temperature, SF6 gas will be partially decomposed, and its decomposition products often contain high toxicity, even in trace amounts, can lead to non-life.
When an indoor switch using SF6 gas as insulation and arc extinguishing medium leaks during use, the leaked SF6 gas and its decomposition products will accumulate in the indoor low-level space, resulting in localized hypoxia and toxicity, posing a serious danger to the life safety of the staff entering the room.
Hazards of SF6 gas leakage
SF6 gas is a colorless, tasteless, odorless, non-toxic, inert gas with a heavier density than air.Pure SF6 is not toxic to humans but cannot sustain life.SF6 is a simple asphyxiant.Exposure to atmospheres with O2 levels less than 19.5% will result in dizziness, unconsciousness, increased drooling, unresponsiveness, regurgitation, vomiting, unconsciousness, and even death.
Exposure to an atmosphere with O2 less than 12% will cause unconsciousness without any aura and loss of self-saving ability. More importantly, SF6 will be partially decomposed under the action of high-voltage arc, and its decomposition products are SF4, SOF2, SF2, SO2F2, HF, etc., which are highly toxic and corrosive, and even a small amount of leakage can cause injury to the person and the equipment, and it is even more important for the operators who often go in and out of the SF6 electrical equipment room to foreknow the leakage point and the amount of leakage of SF6 and the content of O2.
Prescription
Although traditional SF6 gas leak detectors can qualitatively and quantitatively detect SF6 gas leaks, it is difficult to quickly and easily find the location of the leak. In other words, it can only find the leak surface first, and then gradually reduce the scope of leak detection, but can not directly find the leak point.
SF6 is a commonly used insulating gas in high-voltage equipment around the world, but it is also a very potent greenhouse gas. Therefore, any leakage from the equipment may jeopardize the continuity of the power supply and have an impact on the environment.
In order to be able to quickly find leaks, reduce the workload of maintenance and inspection personnel, and improve work efficiency, our optical gas camera comes in handy, so that gas leaks have no place to hide!

Application Cases
With an optical gas camera, it is possible to quickly scan parts of the equipment as well as survey areas that are difficult to access with traditional contact measurement tools.
Our optical gas cameras are capable of quickly, accurately and safely detecting methane, sulfur hexafluoride and hundreds of other industrial gases without having to shut down the system.
In addition, optical gas cameras are able to detect gas leaks from a safe distance, visualizing these gases, which are not visible to the naked eye, as clouds of smoke.
Optical gas cameras can quickly scan large areas and identify the source of leaks more accurately in real time, making them ideal for monitoring equipment that is difficult to reach with contact measuring tools.
Inspectors can scan large areas and check hundreds of components at once in a single inspection, reducing repair downtime and being safe enough to detect possible gas leaks from distances of meters or tens of meters, gas leak detection using optical gas cameras is a more efficient and reliable solution for all aspects of greenhouse gas transportation, storage, production and use. This can be done at all stages of transportation, storage, production and use of greenhouse gases, thus maximizing safety and cost savings.
Once the SF6 gas leaks, it is easy to cause localized hypoxia, resulting in personnel asphyxiation due to oxygen deprivation and death, causing great safety risks to the lives of personnel. Because the degree of insulation is reduced, but also on the high-voltage circuit breaker arc extinguishing effect is also greatly reduced, thus damaging the main body of the circuit breaker.
Therefore, once the SF6 gas leakage is found, corresponding measures must be taken to accurately find the leakage point, repair the leakage point, and promptly eliminate the safety hazards of the high-voltage circuit breaker.
