Pure SF6 gas is colorless, odorless and basically non-toxic. But once the purity is not enough, mixed with toxic impurities, or under the action of high-power arc, spark discharge, corona discharge, SF6 gas will decompose and release a variety of toxic substances. It is assumed that SF6 is not properly controlled during use or that there is a leak during gas recovery. It not only pollutes the environment, but also adversely affects the normal operation of electrical equipment and the health of employees. Therefore, we need to carry o... more

Because the SF6 gas itself contains moisture, the SF6 regeneration gas contains moisture, or the SF6 equipment is mixed with moisture during maintenance, inspection, and gas supply, or the insulating materials and adsorbents in the equipment fail, or the moisture in the atmosphere is sealed through the SF6 electrical equipment There are many reasons such as the weak link infiltrating into the equipment. Moisture is gradually contained in SF6 equipment. We know that moisture has a great impact on SF6 gas and equipment. The amount... more
