简要回顾本安理论及相关标准的发展历史;介绍从不同角度提出的非爆炸性本安判定理论;探讨本安电源实现保护电路和提高功率的方法;在阐明电流变化率对本安性能产生的影响后,提出与此相适应的新评价方法和新火花试验装置需要进一步研究;给出不同类型的本安现场总线结构,总结现有本安现场总线系统冗余电源的结构;最后,展望本安理论与技术相关的研究热点和研究方向.%The paper had a brief review on the development history of the intrinsic safe theory and the related standards and introduced the assessment theory of the non explosion intrinsic safe from the different aspects. The paper discussed the intrinsic safe power applied to protect the circuit and to improve the power. After the statement on the current variation rate affected to the intrinsic performances, the paper provided the related new assessment method and the new spark test device needed to be further studied. The different type intrinsic safe site bus structure was provided. The paper summarized the redundant power structure of the available intrinsic safe site bus system. In the final, the paper had an outlook on the related study focuses and the study orientation of the intrinsic safe theory and technology.
