摘要
为了了解SF6气体的低温液化特性,保证寒冷地区SF6电气设备冬季运行安全,笔者利用SF6气体低温试验装置,在实验室和户外分别对SF6气体的低温液化特性进行了试验,并参考工程中常用的Beattie-Bridgman六氟化硫状态参数曲线和经验公式,绘制了SF6气体状态参数曲线,得到了简明实用的SF6气体状态参数公式。试验结果表明,在低温条件下,SF6气体很容易液化,而且气体压力越高,其液化温度也越高,SF6电气设备在低温环境中运行的SF6气体液化温度不应高于该区域环境最低温度,否则必须采取防止SF6气体液化的措施。
In order to understand the characteristics of SF6 gas low-temperature liquefaction so as to guarantee the safe operation of SF6 electrical equipment in cold area in winter,the author tested the characteristics of SF6 gas low-temperature liquefaction separately in the laboratory and in the open air by using SF6 gas low-temperature testing device,drew the SF6 state parameter curve according to the Beattie-Bridgman SF6 state parameter curve and experience function commonly used in projects,and worked out the simple and practical SF6 state parameter function. The result of test showed that SF6 gas easily liquefies under low temperature. Besides,if the gas pressure is higher,its liquefaction temperature is higher. The SF6 gas liquefaction temperature,therefore,operating in low temperature,must be lower than the lowest environment temperature. Otherwise,measures should be taken to prevent SF6 gas from liquefaction.
