Gaoya dianqi, 2020 车载油浸式空心电抗器面临稳态工作电压可达1 100 k V,为保证安全运行,文中分析了稳态情况下车载油浸式空心电抗器的电场强度分布。为减小有限元建模的复杂程度,文中建立了车载油浸式空心电抗器的简化有限元模型并验证了模型的正确性。电场计算结果表明,车载油浸式空心电抗器的内部绝缘油是保证稳态安全运行,不发生放电的重要绝缘组件。电抗器的环氧树脂外壳形状需合理设置以减小电介质极化带来的高电场强度。加装均压球能使车载油浸式空心电抗器的电场强度峰值减小73.12%,进一步减小放电风险的同时 ...

Gaoya dianqi, 2020 车载油浸式空心电抗器没有铁心,在进行特高压GIL交流耐压试验时工作电压高,工作电流大,可能在周围产生较强的磁场。为确保现场试验人员和电抗器周边设备的安全,研究电抗器周围工频磁场分布十分必要。文中对车载油浸式电抗器进行了电路建模,然后基于毕奥—萨伐尔定律计算了车载油浸式空心电抗器周围工频磁场分布。文中计算得到的结果与有限元法计算结果相符。相比有限元法,文中算法对计算机性能要求低,计算速度快,能提高电抗器工频磁场计算效率 ...

Gaoya dianqi, 2020 车载油浸式空心电抗器进行特高压GIL交流耐压试验时工作电流大,绕组发热功率高。为避免过热故障,研究耐压试验情况下车载油浸式空心电抗器的瞬态温度场十分必要。文中应用有限元法耦合计算了二维轴对称电抗器模型的瞬态温度场和绝缘油瞬态流体场,分析了车载油浸式电抗器的温升和散热特性。车载油浸式空心电抗器依靠绝缘油自然对流散热速率有限,文中计算了两种辅助优化散热措施。外部吹风辅助散热措施易于实现,但散热速率提高有限。环境温度降低辅助散热实现难度适中,降温效果好于外部吹风辅助散热 ...
