摘　　要：外壳防护等级和温升是成套开关柜的两个重要性能参数,两者紧密联系又相互制约。以成套开关柜设计人员对相关标准条款的理解为基础,剖析当前部分用户对防护等级的误解,阐述成套开关柜设计制造中合理选择壳体的防护等级,协调防护等级与温升的矛盾。通过对这两个重要性能参数的探讨,让成套开关柜设计者和用户对外壳防护等级和温升有更深入的理解。Shell protection level and temperature rise are two important performance parameters of a complete set of switch cabinet. On the basis of designers′ understanding of related standard terms and conditions of complete switchgear, analyzes some users′ misunderstanding of protection level, expounds reasonable selection of protection level of shell in design and manufacture of complete switchgear, and coordinates the contradiction between protection level and temperature rise. Through the discussion of these two important performance parameters, designers and users of the complete set of switch cabinet have a deeper understanding of the shell protection level and temperature rise.
