摘要
六氟化硫(SF6)气体以其优良的绝缘和灭弧性能广泛应用于各种高压电力设备中,但它也是一种对环境有很大危害的高温室效应气体,因此迫切需要寻找新的低温室效应的、环境友好的气体替代SF6.研制了灭弧试验装置,对温室效应值较低的c-C4F8气体及其混合气体进行了灭弧试验,利用麦也尔电弧模型得到了电弧时间常数和散出能量常数,并分析了其灭弧性能.结果表明,c-C4F8气体在电力设备中具有一定的应用研究价值.
SF6 gas is widely used in all kinds of high-voltage apparatus because of its excellent dielectric properties and arc interruption capability. However, SF6 is a gas with serious greenhouse effect, so it is urgent to find new kinds of low GWP gas or mixed gas to replace SF6. Through a series of arc distinguishing tests in an arc distinguishing device on c-C4F8 gas or mixed gas, the arc constant and power loss coefficients are obtained by means of Mayr＇ s equation, and the interruption capacity is analyzed. The result shows that c-C4F8 is a kind of gas of practical use and further research value.
