摘要
从安全生产的角度出发,爆炸性环境下电动(电子式)仪表设备选用必须考虑防爆要求。文章从防爆原理切入,研究化工装置中爆炸性气体环境下常用的本质安全型与隔爆型仪表区别,以及根据实际情况选择合适的防爆仪表类型。
From the view point of safe production, in the selection of electric（electronic） instruments which are applied in explosive environment, the requirements for explosion proof shall be taken into account. In this article, based on the principles of explosion protection, the differences between intrinsic safety instruments and frame proof instruments which are commonly used in explosive gas condition in chemical plant were studied. And the selection of appropriate explosion proof instrument on the basis of practice was also discussed.
