Gaoya dianqi电缆终端硅橡胶（SR）绝缘与电缆本体交联聚乙烯（XLPE）绝缘之间良好的界面压力，是保证电缆终端高效安全运行的关键。电缆终端内径处的径向应力为电缆终端与电力电缆间的界面压力，温度的变化导致界面机械应力、界面热应力以及SR绝缘应力松弛特性存在差异，进而影响电缆终端的界面压力。文中采用单变量法研究温度对于界面机械应力、界面热应力以及SR绝缘应力松弛特性的影响，通过实验测得SR以及XLPE试样的线膨胀系数随温度的变化规律，将其分配到三维模型中，利用SR绝缘的超弹性和粘弹性本构模型 ...

Dianci bileiqi, 1990 瞬态过程时的过电压可以引起电动机线圈绝缘的损坏,在直接靠近线圈处装设金属氧化物避雷器,在瞬态过程时,由于阀片有时延,不大有效。此时残压值可能增大到1.5倍起始动作电压值。当火花间隙放电时高频分量足以增大到过电压水平。避雷器从端子箱中取出（根据热稳定的理由）并经过附加电缆接入就会增高过电压每米电缆1kV。将小电容量电容器接入线圈就要求增加安装面积。RC回路降低过电压50％,但不是在所有型式的瞬态过程时都是这样。当无重燃的真空开关时在离线圈很远处装设大电容量的电容器,但是这些电容器不能保证瞬态过程时的保护,
