一种用于SF_(6)高压电气设备的防泄露补气装置

A Kind of Leakage Prefection and Compensation Gas Device Used for SF_(6) High Voltage Electric Equipment

六氟化硫气体(SF_(6))作为极其优越的绝缘、灭弧介质,在变电站电气设备中大量应用。如发生六氟化硫气体泄露事件,未经净化处理和检测不合格的气体都应视为六氟化硫故障气体,有中毒和窒息危险,经过净化处理且检测合格的气体,虽然生物毒性合格但仍具有窒息的危险。六氟化硫气体经过高温电弧燃烧后可分解,产生白色粉尘,有剧毒。电网运行检修人员十分重视做好六氟化硫气体的密封工作,而六氟化硫的补气和在线试验工作是电网运行中必不可少的环节因此,因此在六氟化硫补气和在线试验的过程中保证其密封性是十分重要的问题。目前补气防泄露设计方法存在缺点,本文对此进行研究并提出一种用于SF_(6)高压电气设备的新型防泄露补气装置,解决现场实际问题。

SF_(6) gas, as very superior insulation and arc-extinguishing medium, is a lot used in tlectrical equipment of a substation.If SF_(6) gas leakage appears, it will lead to the risk of poisoning and suffocation.The paper, for this, is studying and puts forward a new kind of lealkage protection and compensation gas device used for SF;high voltage electrie eguipment so as to solue practical ftild problams.
