What are the SF6 gas leak detection methods of GIS equipment SF6 gas is an important debugging item of SF6 circuit breaker, and also the key to ensure the normal operation of SF6 circuit breaker. For the equipment in operation, the density relay is generally used to monitor the leakage of SF6 gas in real time. Once the pressure value drops rapidly or there is an alarm signal, it is necessary to further find the leak part in order to determine the leak part in the shortest time and gain time f

Sulfur hexafluoride itself is a non-toxic and harmless gas, but under the action of high temperature and high pressure arc, it tends to decompose and free a variety of products, mainly S2F10, SF4 and SF2, as well as a small amount of S2, F2, S, F, etc. Some of these decomposers are toxic substances that will cause harm to the human body. At the same time, if a large amount of sulfur hexafluoride gas is inhaled, it will also cause adverse reactions such as asphyxia. But sulfur hexafluoride gas is

SF6 gas is a colorless, odorless, odorless, non-toxic, inert gas that is denser than air and is one of the six greenhouse gases discovered today. SF6 gas is widely used in the high voltage electrical appliance manufacturing industry. Pure sulfur hexafluoride gas is a non-toxic and harmless asphyxiating gas, and there is no toxic sulfur hexafluoride. However, the impure SF6 gas is very harmful to the environment and the human body and equipment. Especially when sulfur hexafluoride gas contains ex

In the switch room filled with SF6 gas equipment, regardless of the amount of SF6 gas leakage, SF6 online detection and alarm device is required. The SF6 online detection and alarm device mainly detects the SF6 gas content and oxygen content in the ambient air. When the SF6 gas content in the environment exceeds the standard or is hypoxic, it can give a real-time alarm and automatically open the fan for ventilation. And has temperature and humidity detection, working state voice prompt, remote a

Sulfur hexafluoride is a century-old gas, which was synthesized by two French chemists, Moissan and Lebeau, in 1900 and made commercially available in 1947. At present, sulfur hexafluoride gas is mainly used in the power industry. Sulfur hexafluoride gas is used in four types of electrical equipment as insulation and/or arc suppression: sulfur hexafluoride circuit breakers and GIS, sulfur hexafluoride load switchgear, sulfur hexafluoride insulated transmission lines, sulfur hexafluoride transfor
