基于辐射降温方式的特高压户内直流场电抗器冷却效果研究OA

The heat dissipation of reactors in DC field is a hot issue affecting the development of UHV technology.For solving such issues in traditional problems as large energy consumption,uneven cooling and dust flying associat-ed with traditional air supply methods and starting from the perspective of the characteristics of reactor as well as in-door environment regulation and control,a novel radiation plate for cooling method is proposed in this paper.A±800 kV UHV DC field in Guangzhou is taken as an example,the structual optimization design of the radiation plate of the reactor is performed and the Fluent software is used to simulate and study the cooling effect of radiation plate placement position on the UHV DC filed.The study shows that the effect is more significant with the radiation plate within 500 mm.The cooling effect of the internal radiation plate to the reactor is better than that of external radi-ation plate.However,the combined effect of the internal and external placement of radiation plate is not significant.
