冷冻冷藏大机组电控箱防护等级设计

Design of Protection Degree of Electric Box for Refrigeration Unit

介绍了冷冻冷藏大型机组提高电控箱防护等级的设计要点和注意事项,从箱体自身结构设计、密封材料、门锁、密封材料压缩量、元器件等方面进行了阐述,指出了各关键要素之间的相互关系对提高IP等级的重要性。对大机组的电控箱防护等级设计给出了指导建议。

The key design points and precautions of enhancing the protection degree of electric box for the largesized refrigeration unit was presented from the aspects of the configuration design of box boby, seal materials,door lock, compression capacity of seal materials and the primary device, the great importance of relationship among these factors on increasing the IP degree was pointed out. Finally, we put forward some guidance for the protection degree design of electric box of large-sized refrigeration unit.
