The decomposition products of sulfur hexafluoride (insulating gas

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price

The sf6 gas Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (insulating gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of gaz sf6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce theGet price

Handling and Use of Sulfur Hexafluoride Gas

B. Decomposition Gasses and Solid By-Products When exposed to sustained or intense electrical arcs, SF 6 gas decomposes to form sulfur-fluoride gases and metal-fluorides which are toxic. If moisture is present, the decomposition by-products may also include sulfur-oxyfluorides and hydrofluoric and sulfuric acids.Get price

Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf 6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what insulating gas can do in centimeters.Get price

Muqtada al-Sadr is the son of Grand Ayatollah Mohammed Sadiq al-Sadr, who founded the prominent Sadrist Movement in the 1980s, a vehemently nationalist political movement popular among Iraq’s Shiite lower class. After Mohammed Sadiq al-Sadr was assassinated in 1999, presumably by the Hussein regime, Muqtada al-Sadr succeeded him as the leader of the Sadrists as well as one of the most powerful and respected Shiite clerics in Iraq. Following the U.S. invasion in 2003, Sadr called upon the Sadrist to join his new militia, the Mahdi Army, with the goal of expelling the U.S. coalition from Iraq and establishing an Iraqi Shiite government. Some of the group’s initial three hundred fighters were recruited in Kuwait and Saudi Arabia and together with their Iraqi counterparts were sent to Hezbollah camps in Lebanon for training.
