摘      要：Modeling the steady thermal field of the column-type air-core reactor,and further analyzing its distribution regularity,will help optimizing reactor design as well as improving its *** operation mechanism and inner insulation structure of a novel current limiting column-type air-core reactor is introduced in this *** finite element model of five encapsulation forced air-cooled column-type air-core reactor is constructed using *** importantly,this paper present a new method that,the steady thermal field of reactor working under forced air-cooled condition is simulated without arbitrarily defining the convection heat transfer coefficient for the initial condition;The result of the thermal field distribution shows that,the maximum steady temperature rise of forced air-cooled column-type air-core reactor happens approximately 5% to its *** law of temperature distribution indicates: In the 1/3 part of the reactor to its bottom,the temperature will rise rapidly to the increasing of height,yet the gradient rate is gradually decreasing;In the 5% part of the reactor to its top,the temperature will drop rapidly to the increasing of height;In the part between,the temperature will rise slowly to the increasing of *** conclusion draws that more thermal withstand capacity should be considered at the 5% part of the reactor to its top to achieve optimal design solution.
