中文摘要:
      温变应力已成为危害变电站支撑式管母系统结构安全的主要因素之一,基于硬管母绝缘子的结构应力约束,本文开展了硬管母系统安装温度对其运行温变允许范围的影响研究。文中基于ABAQUS搭建了变电站支撑式管母系统有限元仿真模型,分高温与低温两类情景开展了传统1/2安装法的管母系统温变结构应力仿真,建立了温变与应力之间的量化拟合数学模型,针对得出的高温、低温安装均不利于管母运行允许温变的结论,给出了考虑安装温度的支撑式管母滑动金具中安装位置计算方法及工程应对策略。研究成果可为变电站硬管母系统的工程安装和安全运行提供指导,具有工程应用价值。
英文摘要:
      Temperature-dependent stress has become one of the main factors that impair the structural safety of the supporting tube bus system of substation. Based on the structural stress constraints of the supporting tube bus insulator, this paper studies the influence of the installation temperature of the tubular bus system on the allowable range of operating temperature change. Based on ABAQUS, the finite element simulation model of the supporting tubular bus system of substation is built. The temperature-dependent structural stress simulation of the tube bus system is carried out in high-temperature installation and low-temperature installation scenarios separately with the traditional 1/2 installation method. A mathematical model of quantitative fitting between temperature range and stress is constructed. Based on the conclusion that high temperature and low temperature installation are not conducive to the allowable temperature change of the tubular bus-bar, a calculation method and engineering countermeasures are proposed of the installation position of the sliding fittings considering the installation temperature. The research results can provide guidance for the engineering installation and safe operation of the substation hard tubular bus system, and have engineering application value.
