摘要

通过在110 kV GIS（气体全封闭组合电器）设备中模拟局部放电故障

研究了在局部放电作用下电极材料、放电强度、气体湿度和吸附剂对SF6分解产物中SO2+SOF2和HF体积分数的影响及其变化规律。结果表明

电极材料、放电强度和吸附剂对SF6分解产物的生成有较大影响

而气体湿度对分解产物的生成影响不大。研究结果为通过SF6分解产物判断设备故障提供了理论基础。

Abstract

Partial discharge was simulated in an 110 kV gas insulated switchgear（GIS）.The effects of electrode materials

discharge intensity

contents of water and absorbents on the yields of SF6 decomposition products（SO2 + SOF2 and HF） were investigated

and the relevant change rules were summarized.The results showed that the electrode materials

discharge intensity and the adsorbents had great influence on the formation of SF6 decomposition products and gas humidity had limited effect.The results will provide theoretical foundation for fault diagnosis of GIS equipments through SF6 decomposition products.
