| 摘 要： | 以某10kV无功补偿装置串联电抗器为例,计算分析了电抗器电场强度的分布,并设计了电抗器专用均压环.以场-路耦合的方法,计算了电位在电抗器匝间的分布,并以此为初始条件,采用电场的有限元计算方法,计算分析了电抗器在正常及冲击电压作用下的电场强度分布特点.根据电场强度分布,设计出电抗器专用均压环,有效减小了电抗器电场强度,对于降低电抗器的故障率,提高电抗器的使用寿命具重要作用.

| Abstract: | The electric field distribution on a air-core reactor,which is used in 10 kV reactive compensation device,is calculated;and the special shielding ring is designed.Firstly,the potential distribution on each turn of reactor is calculated using field-circuit coupling method.Then the electric distribution,both in normal and impact voltage conditions,is calculated.A special shielding ring for reactor is designed according the electric distribution,which is useful to reduce the electric field intensity. |
