摘要
特高压系统用干式空心电抗器系统结构的电位分布不均匀性会引发电晕放电的问题,通过采取配置均压装置有效均匀电场、消减电晕放电以满足工程需要。在建立分析模型的基础上利用有限元的方法计算和分析干式空心电抗器在采取均压措施前后不同情形的电场分布情况。结果表明,采取的措施能有效解决工程设计中的问题,为特高压干式电抗器的研制开发提供了参考依据。
In the ultra high voltage（UHV）system, the non-uniform potential distribution of the dry-type air-core reactor will lead to corona discharge problems. Taking measures of using potential grading device, it can effectively improve electric field distribution and eliminate corona discharges. The analysis model is built in order to calculate and analyze the electric field distribution by finite element method of dry-type air-core reactor. The results show that it would be useful to solve problems in reactor design and could provide the reference to the research and development of UHV dry-type air-core reactor.
