摘要

O气体具有优异的绝缘和环保特性

在中低压电气设备中作为绝缘介质使用具有很好的应用前景

但C

O与气体绝缘设备中常用的三元乙丙橡胶密封材料的相容性在其工程应用前仍待研究。为此通过搭建橡胶相容性试验平台

使用热加速老化的方法研究了C

O/CO

混合气体与三元乙丙橡胶的相容性

并测试了试验后气体成分的变化、三元乙丙橡胶的机械特性、表面形貌和元素变化。研究发现

在热老化条件下三元乙丙橡胶会与C

O和C

反应

使C

O气体分解产生的C

减少

但同时会使C

O气体分解产生的C

O和C

增多;老化试验结束后三元乙丙橡胶表面覆盖了一层油性物质

老化试验会使三元乙丙橡胶脆化降低其机械性能

表面会析出大量晶体颗粒;C

O气体腐蚀三元乙丙橡胶后

会加速三元乙丙橡胶的老化造成其使用寿命缩短。相关试验结果将会对C

O气体绝缘设备的设计和制造过程提供参考。

Abstract

O gas has excellent insulation and environmental protection characteristics

and has good application prospects as an insulating dielectric in medium-and low-voltage grade electrical equipment. However

the compatibility of C

O/CO

gas mixture with ethylene-propylene-diene monomer（EPDM） sealing materials commonly used in gas insulation equipment needs to be studied before its engineering app

lication. In this paper

the compatibility of C

O gas and EPDM rubber was studied by building a rubber compatibility test platform and using the method of thermally accelerated aging. After the tests

the changes in the composition of gas mixture

the mechanical properties

surface morphology and element changes of the EPDM rubber were tested. Studies have shown that

under thermal aging conditions

chemical reactions between EPDM and C

O gas may occur

and EPDM will react with C

O and C

to reduce the C

produced by the decomposition of C

O gas; however

in the meantime

the decomposition of C

O gas will be promoted to produce C

O and C

. After the end of the aging test

the surface of the EPDM rubber is covered with a layer of oily substances. EPDM rubber becomes brittle and reduces its mechanical properties

and a large number of crystal particles will appear on the surface. After C

O gas corrodes EPDM rubber

the aging of EPDM rubber will be accelerated and its service life will be shortened. Related test results will provide references for the design and manufacturing process of C

O gas insulation equipment.
