纯水冷却系统在高原环境中的设计和应用

Design and Application of Pure Water-Cooling System in Plateau Environment

纯水冷却技术是大功率电力电子装置冷却的主要技术,纯水冷却系统准确合理的设计、稳定可靠的运行与电力电子装置同等重要。电力电子装置及其纯水冷却系统在平原地区的应用已有很多工程经验,但在高原地区的设计和应用案例还很少。以西藏某220 kV变电站静止无功补偿装置晶闸管阀纯水冷却系统为例,介绍了在高原地区的设计经验,为纯水冷却系统在其他高海拔地区的工程应用提供借鉴。

Pure water cooling technology is the main technology for cooling high power electronic device.The accurate and reasonable design and stable and reliable operation of pure water cooling system are as important as power electronic devices.There are many engineering experiences in the application of power electronic devices and their pure water cooling systems in plain areas,but there are few design and application cases in plateau areas.Taking the pure water cooling system of thyristor valve of a 220 kV Substation in Tibet as an example,the design experience in plateau area is introduced,which provides reference for the engineering application of pure water cooling system in other high altitude areas.
