现场总线系统的本质安全防爆技术

The Ex i Explosion-Proof Technology in the Fieldbus System

采用本质安全技术制造的电气设备具有重量轻、体积小、成本低的特点 ,还可实现带电维护和 0区危险场所的应用。因此 ,这种技术是现场总线中最理想的保护技术。克服本质安全防爆对现场总线的限制是现场总线在应用理论上的发展趋势。本文旨在了解本质安全防爆技术在现场总线中的应用 。

The essential electric equipment made of the Ex i explosion-proof technology has characteristic with light weight,small volume, low costs and realize electrification maintain and the applications of 0 district dangerous places.So,this technology is the most ideal protection technology in the fieldbus.It is the development trend in the fieldbus practical theory to overcome the restriction fieldbus of the Ex i explosion-proof.This paper aims at finding out the technology application in the fieldbus of the Ex i explosion-proof,Strengthen the study of the Ex i theory in the fieldbus.
