摘要
介绍了计算干式空心电抗器磁场的解析方法,并对空间闭合环路受电抗器磁场影响所产生的环流进行了计算分析,并用试验方法对计算结果进行了验证。结果表明:在空心电抗器的设计安装中,必须考虑诸如围栏、接地网等可能构成闭合环路结构的环流问题。
In this paper, an analytic calculation method of magnetic field of dry type air core reactor is presented, the situation of spatial closed loop influenced by magnetic field of reactor and the circulating currents in spatial closed loop are calculated and analyzed. The calculation results are verified by practical tests. The calculation shows that in the designing and installation of air core reactor the circulating currents in the conducting structures in a certain range, which may constitute closed loops such as grounding nets, etc., must be considered, and these structures must be avoided to be arranged near air core reactors.
