六氟化硫(SF_6)断路器的应用及六氟化硫环保问题

Application and environment protection issues of sulfur hexafluoride circuit breaker

介绍了六氟化硫的性能及应用情况,阐述了六氟化硫断路器的工作原理。指出了六氟化硫断路器的安全隐患和毒性来源。若六氟化硫气体的含水量较高,则将使绝缘水平大大下降,接触电阻急剧增加,在运行中易发生损坏或爆炸事故。总结了六氟化硫断路器5个方面的毒性来源,介绍了工作过程中产生的有毒气体。最后提出了六氟化硫对环境的危害及回收利用问题。

Capacity and application of sulfur hexafluoride were introduced. Working principle of sulfur hexafluoride circuit breaker was elaborate,and toxicity resources and potential safety problem of SF6 circuit breaker were pointed out respectively. Finally the harm of sulfur hexafluoride circuit breaker to the environment and its recycling was also introduced.
