摘要

台灣地狹人稠，在自產能源缺乏下，98%的能源仰賴進口，各國致力於開發再生能源，在各項能源技術中，風力發電是替代能源的可行方式，因台灣四面環海本身屬於海島型和季風氣候區的國家，西部沿海地區、高山和離島地區都蘊藏著豐富風能資源，十分適合發展風力發電，但風力發電機長期在沿海潮溼易腐蝕的環境中運行，機件故障的機率也隨之上升，而風力發電機機艙高度約在60至75公尺，假若發生火災事故，搶救上有極大困難，為避免風力發電機火災事故一再發生，本論文針對風力發電機內部構造進行探討可能的可燃物，並進行火災危害及火災成因分析，本文亦進行細水霧防護系統於風力發電機火應用的探討，NFPA750標準定義細水霧系統為以特殊設計的水噴頭噴撒出細微之水粒子，且99%之水粒子平均粒徑低於1000微米。本文針對細水霧系統進行火災實驗測試，將實驗結果進行分析，發現細水霧系統不僅可以及時滅火並能冷卻火場溫度，防止油類復燃造成二次災害，抑制火災發生時災害擴大，本文之測試驗證細水霧系統用於風力發電機火災防護有其有效性與可行性。

Through extensive research and testing, water mist systems have gained worldwide acceptance as an effective solution in many applications, such as those that involve flammable liquids, electrical equipment, semiconductor facilities, and outdoor transformers. The NFPA 750 standard defines “water mist” as a water spray discharged through a nozzle in which 99% of the water spray’s volume comprises water particles less than 1,000 microns in diameter. A water mist system combines the key suppression mechanisms of heat absorption, oxygen displacement and radiant heat blocking to control, suppress and extinguish fires. In addition, water mist systems provide the following advantages over other systems: superior fire suppression, smoke absorption capability, minimal water damage, non-toxicity, non-asphyxiating, and environmentally friendly.
Wind generators have become very popular lately as a means to generate power for today’s life. The height of wind generator is always 60 to 70 meters. If the cabinet is in fire, it will be hard to response for fire fighter. A fixed fire suppression system is a good solution for fire protection. For the good performance of water mist system, this study wants to develop a water mist system for wind generator fire protection. Through series of fire tests, the water mist system is proofed to have good effectiveness on fire suppression in wind generator fire.
