摘要

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

缓解了高场强可能导致的介质老化。

Abstract

Rated voltage of vehicle-mounted oil-immersed air-cored reactor is up to 1 100 kV.To ensure the safety during operation

the steady electric field of vehicle-mounted oil-immersed air-cored reactor is analyzed.In this paper

a simplified finite element model of vehicle-mounted oil-immersed air-cored reactor is created and the correctness of this model is verified.According to the electric field calculation result

the insulation oil in the reactor is very important to avoid discharge.The geometry of the epoxy resin shell should be set reasonably to reduce the electric field strength caused by dielectric polarization.By applying the shielding ball

the peak of electric field strength is reduced by 73.12%.The risk of discharge reduces and the dielectric aging caused by high electric field strength is avoided.
