变电站除湿技术研究

Research on dehumidification technology for the substation

针对变电站普遍存在的户外密封箱凝露问题。比较了在役3种除湿方式的优劣,介绍了一种基于半导体冷凝技术开发的新型除湿装置,并简介了该装置的构成。经挂网运行,发现除湿效果较为明显。结果表明,新型除湿装置设计是合理且有效的。

Aiming at the condensation problem of outdoor sealed box commonly existed in substation,there were some advantages and disadvantages of three dehumidification methods in service compared,and a new dehumidification device and the structure based on semiconductor condensation technology was introduced.It was found that the dehumidification effect was more obvious using the new device after network operation.The results showed that the design of the new dehumidifier was reasonable and effective.
