摘要
六氟化硫（SF6）断路器因开断电流大、灭弧性能强、不易发生重燃和截流过电压、使用寿命长等特点，广泛用于110—550kV高压系统中。但SF6在2000℃以上分解形成的水和有毒的腐蚀性气体，对绝缘造成严重危害。预防SF6气体的泄漏、断路器绝缘水平下降、电器部件的腐蚀是一项重要任务，必须采取有效措施加以解决。
SF6 circuit breakers are widely used in 110 -550kV high voltage systems, because of high on-off circuit.strong arc suppression,not easy reignition and cut-off overvoltage and long life features and so on. But SF6 which is resolved into water and toxic corrosive gases above 2000℃ is serious harm for insulation. It is an important job to preventSF6 gas from leakage, insulation level of circuit breaker reducing and element corrosion. Effective measures must be take.
