Abstract
Taking an underground gas-insulated metal-enclosed transmission line(GIL)corridor with a ventilation system as the research object,the numerical analysis method was adopted to establish the physical and mathematical model of GIL corridor by using Fluent software.The influence of air supply and exhaust on the temperature of the corridor was fully considered.Reasonable initial and boundary conditions of the corridor space were set.The thermal environment changes of GIL corridor in summer and winter and at extreme temperatures as well as temperature changes at different locations were analyzed,and the difference between normal and abnormal working conditions was compared to reveal the spatial temperature distribution characteristics.The results show that under the natural ventilation and mechanical exhaust mode,the temperature inside the GIL tunnel gradually increases along the length,with the highest temperature at the end of the tunnel,which can meet the requirements of the"Code for design of power cables tunnel"(DL/T 5484-2013).In the event of abnormal conditions in summer,the temperature at the tail is relatively high and can be improved by increasing the air inlets and wind volume;in winter,natural ventilation and natural exhaust methods can be considered.关键词
