摘要
本文笔者对500kV天然酯绝缘油与矿物油变压器进行数值模拟,通过施加与温度变化密切相关的绝缘油物理参数,对天然酯绝缘油与矿物油的油流温升进行了对比。计算发现不同冷却介质下绕组热点温升位置不同,后期通过温升试验进行了验证。
Appling numerical simulation method in 50okV natural ester and mineral oil transformer,adopting different physical properties of natural ester oil and mineral oil,which changing with temperature,we find the local of hot-spot temperature rise is change.The temperature rise results are compared with testing data.For the future temperature rise measure of optical fiber temperature measurement,he author gives her own opinion.
