With the wide application of SF6 in ultra-high voltage and UHV circuit breakers, it has replaced oil as an arc extinguishing medium, and has largely replaced compressed air. There are more and more instruments used to detect whether SF6 leaks on the market. Today, we will understand what are the SF6 gas leak detectors?

?I?.Portable SF6 gas leak detector

?A highly accurate, highly sensitive leak detector that uses non-dispersed red external (NDIR) technology to locate and quantify leaks. It is mainly used in leakage detection of GIS and SF6 inflatable equipment in power industry. It can detect the leakage of SF6 electrical equipment qualitatively and quantitatively. And accurately locate the leakage failure point of SF6 gas electrical equipment. The instrument is portable, can be hung on the body to carry, the instrument is light and compact, easy to use.

II.?Conventional SF6 gas leak detector

?It can be used for qualitative and quantitative testing of SF6 gas electrical equipment. The annual leakage rate of SF6 gas electrical equipment was measured by bandaging method. At the same time, the equipment is widely used in power supply bureaus, substations, high-voltage switch companies, laboratory safety fume hoods, scientific tests and other fields of SF6 gas leakage detection. The test speed of the instrument is fast, the data stability can be reached 10s, and the data repeatability is good.

III.Infrared imaging leak detector

?The principle of infrared focal plane method is used to design the instrument, which ensures the sensitivity and reducibility of the instrument. The instrument has the advantages of simple and reliable design, high test sensitivity and clear image, and can find the SF6 gas leakage point of electrical equipment accurately and quickly in the work site. No matter what kind of SF6 gas leak detector, the choice must be based on the performance indicators and after-sales support, so that it can be easily used.
