    • 工業之輸配電系統中，如開關箱內發生電弧閃絡，高熱、強光、高分貝之巨響及壓力等現象容易隨之而來。除對設備造成莫大之損傷外，更可能危及人員之安危。為故，本研究歸納一套電弧閃絡分析方法，進而探討適用於高低壓配電箱等級之法，以及評估其危險程度並提出降低電弧能量之手段，實施相應之防護措施。本文使用電力系統分析軟體針對電弧電流、電弧能量及電弧保護邊界模型進行模擬，而低壓電弧以IEEE 1584-2018版分析結果；高壓電弧則以三種較代表性方式評估電弧能量，保守評估電弧危害等級。最後提出降低電弧危害的手段，分別以抑制故障電流、調整既設傳統保護協調、區域選擇性閉鎖、遠端控制等方式保護設備及人員安全。

    In the industrial power distribution system, if an arc flash occurs in the switch box, high heat, strong light, high decibel noise, and pressure are likely to follow. In addition to causing great damage to equipment, it may even endanger the safety of personnel. For this reason, this study summarizes a set of arc flashover analysis methods and then discusses the method applicable to the level of high-voltage and low-voltage distribution boxes, as well as assesses the degree of danger and proposes means to reduce arc energy, and implements corresponding protective measures. This paper uses power system analysis software to simulate the arc current, arc energy, and arc protection boundary model.Low-voltage arc is analyzed by the IEEE 1584-2018 version; the high-voltage arc is evaluated in three representative ways. The arc energy is conservative assess the arc hazard level. Finally, the means of reducing arc hazards are proposed, respectively, to protect equipment and personnel safety by suppressing fault current, adjusting existing traditional protection coordination, regional selective blocking, and remote control.
