摘要

选用了电力设备中常用的吸附剂KDHF-03分子筛

模拟研究了吸附剂对电力设备中SF

气体在局部放电下分解特性的影响

特别关注了SO

、SO

、S

等几种典型分解产物添加吸附剂前后的产生规律。结果表明

添加吸附剂后

3种产物的含量均明显降低

与S

两种产物的吸附率(体积分数)分别达到79.92%和78.73%

含量则始终低于气体分析系统的检测限度。此外

引入吸附剂之后

与S

的产生速率随着加压时间逐渐降低

其含量随时间延长逐渐饱和。最后

提出将φ(S

)/φ(SO

)作为SF

类设备绝缘缺陷诊断判据

该比值在有、无吸附剂两种情况下表现出了很好的稳定性

添加吸附剂前后其值均稳定在1.5～2.0之间。

Abstract

KDHF-03 molecular sieve

a kind of adsorbent commonly used in electrical equipments

is chosen to investigate the effects of absorbents on SF

decomposition characteristics under partial discharge. The formation laws of several typical products

including SO

、SO

、S

before and after adding adsorbents

are focused on. The results show that the contents of these three kinds of decomposition products obviously decrease after adding adsorbents

the adsorption rates

of SO

and S

get 79.92% and 78.73% respectively

and the amount of SO

even falls below the detection limitation of gas analysis system. In addition

the productive rate of SO

and S

decreases with the pressurization prolonging. Finally φ(S

)/φ(SO

)

which remains within 1.5—2.0 before and after adding adsorbents

is suggested as diagnosis criterion for insulation defects in SF

gas-insulated electrical equipment.
