仪器仪表本安电路设计及火花安全评估方法

摘要

Intrinsic safety technology is widely used in production process of oil, chemical industry, coal mining and so on, many kinds of new intrinsic safety equipments are applied in the dangerous environment. This paper discussed intrinsically safe circuit design method and spark safety assessment method based on the related standards to strengthen the function, improve safety performance, and shorten the certiifcation period of instrument.%本安防爆技术广泛应用石油、化工、煤炭开采等生产过程中，各种新型本安设备也越来越多的应用于这些危险环境中。本文结合相关防爆标准，探讨了本安电路设计及其火花安全性能的评估方法，对增强设备功能、提高产品本安性能及缩短认证周期具有一定的指导作用。
