摘要
本文针对某水电站离相封闭母线抱箍局部温度过高问题,进行了深入分析与研究。首先,通过对比计算分析与仿真计算结果,确定了问题原因;其次,对比更换抱箍材料与采取在抱箍上安装接地线两种方案的特点,最终选取在抱箍上安装接地线的方案降低离相封闭母线抱箍温度,逐步消除离相封闭母线抱箍局部高温现象;最后,针对此类故障,提出了相应解决方法,为其他水电站处理此类问题提供参考。
This paper analyzes and studies the problem of the local high temperature of the isolated-phase enclosed busbar hoop in a hydropower station,and determines the cause of the problem by comparing the results of calculation and simulation.By comparing the characteristics of replacing the hoop material and installing the ground wire on the hoop,the scheme of installing the ground wire on the hoop is finally selected to reduce the temperature of the isolated-phase enclosed busbar hoop,and gradually eliminate the local high temperature phenomenon of the isolated-phase enclosed busbar hoop.Aiming at such faults,the corresponding solutions are put forward,which can provide reference for other hydropower stations to deal with such problems.
