计及电缆绝缘不均匀老化的接地电流相位角特性研究

Gaoya dianqi
交联聚乙烯（XLPE）电力电缆广泛应用于配电网和输电网，但它们在持续的电应力下遭受长期的老化退化，电缆老化容易造成绝缘击穿事故。为了提升电缆绝缘老化状态的在线评估技术，基于PSCAD建立了计及电缆绝缘不均匀老化的三芯管型电缆接地电流相位角计算模型，通过快速傅里叶变换FFT变化得到单相不均匀老化、双相不均匀老化、三相均匀老化3类情况的接电线电流相位角特性。结果表明：相比于钢铠接地线电流，屏蔽线电流相角对于老化特性的反应更为灵敏；对于单相老化，介电常数由2增加为5，屏蔽线电流相位角从-51.01°递增为 ...

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 ...
