缩空气到同样的绝缘强度要0.6~0.7MPa。SF6气体提纯设备众博棋牌之所以具有较高的绝缘强度是由卤族化合物的负电性,即对电子的吸附能力造成的。卤族元素中又以下元素的负电性最强,它的化合物SF6仍有强负电性。在温度不太高的情况

      (2)SF6气体提纯设备的灭弧特性。SF6是一种具有优异灭弧性能的气体,这是由它独特的热特性和电特性所决定的。SF6提纯设备气体的优良灭弧性能也是由其高温下的分解,使气体降温,导热系数增大及随后的复合过程加快所决定的。SF6气体中电弧时间常数小,约为空气的1/100,即SF6气体的灭弧能力为空气的100倍。在气吹灭弧下,大量SF6分子不断和电弧接触使灭弧更加迅速。大电流电弧试验表明,SF6的开断能力为空气的2~3

     (3)SF6提纯设备的导热特性。它作为电器的绝缘介质,导热性要好,以避免温升过高。SF6气体提纯设备的热导率是不高的,比空气低1/3。SF6气体分子间通过碰撞传递动能而形成传热能力,其定压摩尔热容大约为空气的3.4倍,因此,SF6气体提纯设备的对流传热能力比空气大得多,2个大气压SF6的对流传热能力与变压器油相同。此外,SF6气体的黏度低于空气,流动性好。因此,如果一并考虑对流传热,SF6气体的实际传热能力比空气

  综上所述,SF6气体提纯设备具有良好的绝缘特性、灭弧特性和导热特性。因此,SF6气体提纯设备广泛应用于输变电设备上,作为绝缘和灭弧的介质。
