    • 工業配電系統之開關箱內部發生弧光閃絡時，會伴隨高熱、強光、高分貝巨響及壓力等物理現象，對人員及設備會造成莫大之危害。為了評估其危險等級，IEEE經過多次實驗歸納出一套弧光閃絡分析模型，可於評估後依據危險等級實施相對應之防護措施。IEEE首度在2002年建立IEEE 1584標準。經過多年的實際驗證與經驗積累後，在2018年發表了更新版IEEE 1584，其內容已與舊版大相逕庭，弧光閃絡分析模型重新推導，並調整了弧光分析所需之各項參數。為比較新舊版模型之差異，本論文利用分析軟體對針弧光電流、弧光能量及弧光保護邊界模型，測試各參數變化，如開關箱尺寸、導體配置等因素對分析結果的影響程度。結果顯示電壓範圍為601V~15kV之開關箱發生弧光閃絡時，新版弧光能量模型下會比舊版模型有更大的弧光能量，而弧光保護邊界則大幅減少；電壓範圍208V~600V之開關箱的弧光能量、弧光保護邊界與舊版相比則相差無幾，導體配置方式中則以HCB相對於其他配置方式會有更大的弧光能量。

    In the industry power systems, the arc flash fault inside the panelboard phisicially accompanied with extra high heat, strong light, loudly decibel noise and heavily pressure, will endanger people and equipment nearby. To evaluate the risk degree of each panelboard the IEEE society setup an analytical arc flash calculation model. Moreover, it also gives a countermeasure according to the degree of risk. The first edition(old) of standard about arc flash evaluation IEEE 1584 was proposed in 2002. After years of review and improve, a new edition of IEEE 1584 announces in 2018. It shows much revise in arc flash calculation model than 2002 edition. To test the differences in arc flash model including arc current, incident energy, and arc protection boundary, a software is introduced. In addition, the various of parameters such as panelboard size and conductor configuration may impact the final results also being enhensively investigated. The results show that when the arc flash fault is in 601V~15kV level panelbosrd, new edition model will present much more incident energy and far less protection boundary than old edition. Furthermore, when the arc flash fault is in 208V~600V level panelbosrd, no matter the approach is using new edition model or old edition model there are no obviously difference in arc flash risk assessment. Regarding to the configuration type of conductor inside the panelboard, HCB will present the highest incident energy than other types.
