摘　　要：电弧危险分析有两种常用方法:1)入射能量分析法;2)电弧PPE分级法。入射能量分析法是一种定量精确计算法,电弧PPE分级法是依据《工作场所的电气安全标准》(NFPA 70E-2018标准)的查表对照法。两种方法各有其适用条件和实施要求,通过对两种分析方法的说明和对比,认为我国工厂企业适宜采用入射能量分析法。基于IEEE 1584-2018实验推导模型的入射能量分析法,提供了全面的实施步骤和说明,可以帮助工厂企业全面规范地进行电弧危险评估与控制。There are two valid methods for arc flash hazard analysis:1)the Incident energy analysis;2)the arc flash PPE category method.The incident energy analysis method is a kind of quantified analysis,and arc flash PPE category method is a kind of table look-up scheme as per NFPA 70E-2018 Standards.The two methods have the different applicable scope and the effective conditions.This article elaborates the contents of two methods and conducts the comparison between the two methods,then the incident energy analysis method is approved to be suitable for the factories in China.Finally,the article puts up a complete scheme of arc flash hazard analysis based on the incident energy analysis method involve IEEE 1584-2018 experimental derivation model,and the scheme and the concrete measures can instruct a facility to implement an effective arc flash hazard evaluation and control program.
