摘要
分析了变压器在直流偏磁下振动的偏置特性,提出了一种研究长时间直流偏磁下垫块偏移的建模方法,获得变压器长期直流偏磁运行情况下的垫块的偏移特性曲线,并研究了此时变压器抗短路能力性能。
The vibration bias characteristics of transformer under DC magnetic bias are analyzed theoretically,and a modeling method is proposed to study the migration of cushion block under DC magnetic bias for a long time.The migration characteristic curve of cushion block under DC magnetic bias operation for a long time is obtained and the anti-short-circuit performance of transformer is studied.
