【摘要】 高压直流输电中晶闸管阀能否可靠并安全地实现冷却是非常重要的,而工程实际中主要应用水冷却技术。本文以某公司实际工程应用为背景,论述了高压直流输电晶闸管阀的整个水冷却过程,并基于fluent软件对内冷却系统的单个晶闸管冷却模型进行了仿真研究,考察了相关参数对水冷却效果的影响,并以仿真结果为依据做出了分析,从而为工程应用中的水冷却技术提供了参考数据。更多还原

【Abstract】 It is of great importance for the thyristor valve in D.C.high-voltage transmission to be chilled reliably and safely. Considering that the water cooling technology is usually used in practice,this paper discusses the whole process about water cooling in D.C.high-voltage transmission based on some real company’s application background.By using the Fluent software, the thyristor’s water cooling model of the internal cooling system is simulated through a simplified model,Based on the simulation results,the influence of some relative parameters to the water cooling effect is analyzed,which can provide the reference date for applying the water cooling technique in the application.更多还原
