Characteristics of sulfur hexafluoride gas:

Pure sulfur hexafluoride gas is non-toxic, but during high current interruption, strong arc discharge can produce some sulfur-containing low fluoride compounds. These substances have strong reactivity and will further react with electrode materials and water when there is water and oxygen, thereby decomposing and producing toxic or highly toxic gases. These toxic gases mainly damage the respiratory system of the human body. After poisoning, adverse reactions such as colds, skin allergies, nausea and vomiting, and fatigue may occur. When inhaled in large doses, more serious consequences may occur, so online monitoring is needed to prevent poisoning.
