摘要
石油化工装置爆炸危险区划分和防爆设计是设计中的一项基础性工作,由于尚没有针对仪表防爆的标准规范,导致以往概念上存在一定的空白和误区。通过对国内外防爆标准规范的学习,系统分析了爆炸危险区和防爆仪表的概念,并举例说明应用,以求正确指导仪表防爆设计。
In the design of petrochemical plant, the classification of hazardous area and explo protection design is a foundational work. However, there is no standards and specifications for explo protection design of instrumentation, that causes mistakes in concept. Based on to study Chinese international explosion protection standards the classification of hazardous area and concept of explo protection is analyzed with application examples, which can be used as the guideline for instrumenta design with respect to explosion protection slon sion and sion tion
