摘　　要：35KV干式并联空心电抗器在电力系统应用中越来越广泛,其运行事故的发生给电力系统安全带来很多问题。局部过热是引发电抗器故障的重要原因之一,电抗器的发热主要是由导线自身电阻损耗和导线的涡流损耗引起,因此对电抗器绕组中涡流损耗的分析计算是十分重要的。本文将考虑绕组因为涡流效应所产生的损耗,并利用ANSYS Workbench仿真软件对35KV并联干式空心电抗器进行三维流场—温度场耦合计算,仿真出电抗器的温度场分布。分析讨论绕组涡流损耗对温度场的影响。35KV Parallel dry type air-core reactor is more and more widely used in power system, and its operation accident brings many problems to power system safety. Local overheating is one of the important causes of reactor failure, heating reactor is mainly caused by the eddy current loss of wire loss and self resistance of the wire, so the analysis and calculation of eddy current losses in the windings of reactor is very important. This paper will consider the loss due to eddy current effect caused by winding, and coupled three-dimensional flow field and temperature field calculation of 35KV Parallel dry type air-core reactor using ANSYS Workbench simulation software, simulation of temperature distribution of reactor. The influence of eddy current loss on temperature field is analyzed and discussed.
