基于ReaxFF的聚异丁烯高温裂解机理及影响因素研究

Gaoya dianqi
作为高压电缆终端中的常用填充剂，聚异丁烯（polyisobutylene，PIB）的高温裂解机理尚不明晰。文中利用ReaxFF反应分子动力学软件，获得了聚异丁烯在2 400 K和3 000 K下的裂解产物及其生成路径。研究结果表明，3 000 K下PIB高温裂解产物体积分数均高于2 400 K，表明老化温度升高会加速PIB的裂解及各特征气体的生成，且H2及CH4可作为PIB高温裂解的主要特征产物，并在473 K下开展了PIB热老化验证了数值模拟结果的有效性。同时，为探究影响PIB产气特性的关键因素 ...

检测SF₆分解产物的半导体传感器筛选与识别方法研究

Gaoya dianqi
六氟化硫（SF6）因其优越的电气性能和化学稳定性成为气体绝缘开关设备（gas insulated switchgear，GIS）等高压电气设备的首选绝缘介质。当SF6电气设备内部发生局部放电等故障时，SF6气体会发生分解反应，产生SO2、H2S等物质。而SF6气体分解产物的组分体积分数反映了电气设备的运行状态。因此，监测设备内部的气体组分能够有效评估SF6电气设备的运行状况，从而对设备内部可能的故障起到预警作用。文中通过搭建气敏测试平台 ...
