摘要
通过选取某电网公司下属一处220 kV变电站作为评价研究对象,对该变电站的通风量设计符合性、报警装置有效性进行评价。结果显示,该六氟化硫电气设备室通风量只能满足正常排热通风换气次数2次/h。此外,六氟化硫报警装置中的氧气和六氟化硫传感器均不能正常报警,存在一定的安全隐患。
A 220 kV substation was selected for the safety evaluation on conformity of ventilation design and validity of SF6 alarm. The results showed that the ventilation rate can meet the normal air exchange frequency 2 times/h. In addition, the oxygen and sulfur hexafluoride sensor are not normal alarm in sulfur hexafluoride alarm devices, which is a certain security risk.
