根據統計，台閩地區近十年來平均每年火災發生次數達10,571次，造成230人死亡及695人受傷，並造成新台幣約32億元的直接財物損失，其中以「電氣設備」火災平均每年發生2,241件，持續佔當年度的第一位，比率約為全部火災發生原因與次數的23.9％[1]。
另為考量建築成本回收及電磁波、噪音等問題造成鄰近住戶的抗議，台電、工業廠房、商業及住宅建築物等紛將變配電室設置於屋內或地下層密閉空間，該電力設備場所具有穿越空間區劃管線眾多、空間容積小、採光通風困難、避難出入口位置與數量受限及災害發生時救援補給不易等建築特性，若不幸發生火災事故時，將因氧氣供應不足，造成不完全燃燒或悶燒，再加上電力設備火災多屬PVC、PE等塑膠類絕緣被覆材的燃燒，會產生大量的濃煙，濃煙隨著垂直管道與平面配管到處流竄，火害危險度將擴大。
本論文以屋內電力設備場所火災之行為做研究，首先研究電力設備的熱源、熱傳遞方式及燃燒特性與危害；再採用西元2004年NIST修正之FDS作模擬工具，求得電力設備在起火燃燒後該場所煙、熱與時間的相關數據；本論文提出（1）弧光偵測、PD監測、抽氣式煙霧檢測系統、線型感溫電纜、煙熱雙迴路偵測系統等事前的預防偵測和控制技術，（2）對於燃燒時穿越樓層或區劃之電纜線槽與配管排內外的煙、熱阻絕方案，以防止火勢及煙流蔓延，（3）歸納現行有關屋內電力設備場所防火安全相關法令規定未臻完善或有相互牴觸的地方，提出建議及可行修正方向，作為日後行政措施之考量及後續研究之參考。

The statistics showed that there were 10,571 fires averagely in Taiwan every year during the last decade and the fires have caused 230 deaths, 695 injuries, and a total of 3.2 billion NT of loss. Among all of the fires, the top cause of fire is by electric equipment which resulted to 2,241 fires. 23.9% out of all of the causes.
Taiwan Power Company, industry plants, business and residential buildings have built the electric power distribution room indoors or underground enclosed area under the consideration of cost of construction, electric wave and noise problems which have attracted protests from the neighboring residents. These electric power centers are usually very small, clustered with cables, poor lighting, poor air circulation, limited emergency exits, and that will cause difficulties for rescue. When a fire has happened, the supply of oxygen will be insufficient which will result to incomplete burning. With the help from the plastic PVC or PE insulation jacket of the electric equipments, excessive amount of smoke will be produced and will flow all over the building through the vertical and surface pipes which will expand the fire.
Indoor electric power center is being used as a tool for the study of behavior of fires. First of all, the heat source of the electric equipment, heat transfer method, and the characteristics and damage of burning will be studied. Following with the application of FDS published by NIST 2004, we can get the statistics regarding the smoke and heat when the electric equipment is on fire. With it, we suggest: (1)Arc detector, PD detector, VESDA, linear heat detector, heat and smoke detect system being applied to prevent and control the fire. (2) Ways to arrange the cable tray and piping in the throughout floors to block the smoke and heat in order to prevent the spreading of the fire. (3) Offer suggestions to the administration to fix the safety rules that are contradicting.
