电力柜智能除湿系统研究与设计

Research and Design of Smart Dehumidification System of Electric Cabinet

针对电力柜内部电力设备工作的安全性和稳定性受环境影响的问题,分析半导体制冷器的工作原理,并结合我国南部地区湿度较大这一实际情况,设计基于单片机和半导体制冷技术的智能除湿系统.该系统的特点是:根据箱内温湿度条件自动启停除湿器,将电力柜内的湿空气快速凝结成水排出箱外,达到自动降温除湿的目的;具备故障检测和报警功能,将相关数据信息通过串口发送至上位机,实时监测箱体的温湿度及除湿器的运行状态;与传统的防潮除湿设备相比较,具有控制灵活、温湿度检测准确、功耗低等优点,除湿效果良好.

In view of the security and the stability of the power equipment inside cabinet influenced by the environment ,especially the humid air in the south of our country ,an intelligent dehumidification system was designed based on single chip and semiconductor refrigeration technology according to the working principles of the semiconductor refrigerator .The system can start or stop dehumidifier automatically ac‐cording to the humidity inside the cabinet by condensing the humid air into water and exhausting it outside the cabinet .The system also posesses fault detection and alarm function by sending the body temperature , humidity and dehumidifier running state to the real‐time monitoring in PC through the serial port .Com‐pared with the traditional moisture proof and humidity control equipment ,it has the advantages of flexible control ,accurate temperature and humidity detection ,low power consumption and effective dehumidifica‐tion .
