GIS设备中吸附剂的合理选择与设计要点

Reasonable Selection and Design of Adsorbent in GIS Equipment

为控制水分和SF_6气体分解物的含量,以GIS为代表的SF_6绝缘类电力设备内部必须加装吸附装置,利用吸附剂吸收GIS内部残留的水分和电弧分解物。本文详细分析了GIS设备水分超标的主要原因和水分对GIS设备的危害,介绍了GIS设备对吸附剂的基本要求、吸附剂的种类及特性、吸附剂合理用量等内容,同时针对GIS的典型故障,介绍了吸附装置的设计要点。

In order to control the content of moisture and SF6 gas decomposition products, the SF6 insulation type electric power equipment, which is represented by GIS, must be equipped with an adsorption device inside, and the adsorbent can absorb the residual moisture and arc decomposition products inside the GIS. This paper analyzed in detail the main causes of GIS equipment moisture and water hazards to GIS equipment, introduced the basic requirements of GIS equipment, adsorbent type and characteristics, the amount of adsorbent and other content, while for the typical GIS fault, the design of the adsorption device was introduced.
