摘要

直流场内电抗器散热是影响特高压技术发展的热点问题。为解决传统送风方式能耗大、降温不均匀以及尘埃飞扬等问题，从电抗器特性以及室内环境调控角度出发，文中提出了一种新型辐射板降温方法，并以广州某±800 kV特高压直流场为例，对电抗器辐射板进行结构优化设计，利用Fluent软件模拟研究了辐射板放置位置对特高压直流场的降温冷却效果，研究表明：辐射板放置距离在500 mm以内的效果更显著；内置辐射板比外置辐射板对电抗器冷却降温效果更好；内外兼置的辐射板放置方式综合效益不显著。

Abstract

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 associated with traditional air supply methods and starting from the perspective of the characteristics of reactor as well as indoor 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 radiation plate. However

the combined effect of the internal and external placement of radiation plate is not significant.
