SF_6开关设备微水含量优化处理

Optimization of Water Content in SF_6 Switchgear

本文通过多种措施对SF_6开关设备中存在微水含量超标问题进行分析和逐项处理。通过合理的热烘烤清除零部件固有分水、利用适当时间抽真空对装配中引入的水分进行清除,设置适量的专用分子筛对渗入水分进行吸附处理,优化密封工艺,最终将微水控制在合格范围内,为相似类型电气设备微水控制提供有价值的参考。

In this paper,through a variety of measures,the problem of ultra super standard water content in SF6 switching equipment is analyzed and processed item by item. Clean the natural water separation of parts by reasonable heat bake,remove the moisture introduced in the assembly by pumping the vacuum at the appropriate time.,adsorption of infiltration water by proper proper molecular sieve,optimization of sealing process. Finally,the micro water is controlled within the range of qualification. It provides valuable reference for the control of water micro control of similar types of electrical equipment.
