摘　　要：六氟化硫(SF_(6))气体由于其优良的绝缘和灭弧性能被广泛应用于各类中高压电气设备中,但当设备内部存在微量的水和氧气等杂质时,SF_(6)会发生不同程度的分解并进一步生成各种复杂的产物。本论文从化学角度讨论分解产物的产生机理及常见的化学检测方法,对目前杂质气体的吸附处理、痕量检测和催化降解技术进行了综述,并对可能替代SF^(6)的新型绝缘气体进行了展望。Sulfur hexafluoride(SF_(6))is widely used in various medium and high voltage electrical equipment because of its excellent insulation and arc extinguishing performance.However,when there is a small amount of water,oxygen and other impurities in the equipment,SF_(6) will decompose and generate many kinds of complex products.The generation mechanism of decomposed products,trace chemical detection methods and catalytic degradation are discussed from the chemical point of view,current adsorption treatments and trace detection technologies of impurity gases are summarized and the new insulating gases that may replace SF_(6) are proposed.
