摘要:	為有效降低電氣火災發生率，本研究探討積污導電發生時，如何有效地控制異常升溫持續進行導致可能衍生的電氣火災。透過檢視國內各項法規、近年相關專利發明、相關文獻研究並配合積污導電實驗，探討溫控預警保護裝置對積污導電發生時之控制或預警效能，經由檢視國內法規發現有關積污導電現象預防措施之規定相當罕見，顯見國內有關電氣安全相關法規仍有改善空間。本研究之目的在於探討灰塵等產生積污導電之最適控制溫度，以灰塵等介質進行模擬積污導電試驗以探討積污導電現象，並採用溫控預警保護裝置以預警並控制電路異常升溫。依據日本JIS C 8303插頭插座升溫試驗方法，分析並探討各種積污導電條件之控制點溫度，本研究發現電解液均容易使積污導電反應劇烈，而其餘水份介質在緩和的狀況下反應，其系統溫度亦隨著時間慢慢蓄熱而升溫，即使插頭插座本體未引起燃燒，卻可能引起周遭之可燃物燃燒而引發火災。劇烈的積污導電反應時間雖短暫，但會使插頭插座材質熔解，長期下來易使導線絕緣失效，由此可知插頭插座定期清潔的重要性。配合有效的預警、保護裝置，期能有效預防積污導電引起之火災，研究結果可提供業界設計、製造相關保護裝置時之參考依據，並導正電器用品之不當使用習慣。 In order to reduce the incidence rate of electric fire effectively, the study aims to investigate how to effectively control the continuously abnormal temperature rise that may cause to electric fire when deposit electric conduction occurs. By examining the domestic laws and regulations, recent patent-related inventions, and relevant literature studies, and coordinating with the experiment of deposit electric conduction, investigation of control as well as warning effectiveness of the temperature control device with forewarning and protecting function when deposit electric conduction occurs is conducted in this study. By reviewing the domestic laws and regulation, it is found that regulations about prevention measurement for deposit electric conduction is very rare; in other words, the study discovers that there is room for improvement to the domestic laws and regulations of electrical safety. The objective of the study is firstly to investigate the optimum temperature control of deposit electric conduction that is caused by the dust and then to proceed the simulation experiment of deposit electric conduction by applying dust as the medium in order to discuss the phenomenon of deposit electric conduction; following with application of the temperature control device with forewarning and protecting function to control the abnormal temperature rise in the circuits. In accordance with the experiment method of Japan JIS C 8303 on the plug and socket heating-up, and after analysis and investigation on the control temperature points under various condition of deposit electric conduction, the study discovers that the electrolyte can easily cause to vigorous reaction to the deposit electric conduction while the other water-content mediums reacted under the mild condition; the temperature of the system is also heated up by gradual heat accumulation. Although the plug and socket are not under burning condition, the heat may cause to fire while the combustible materials in the surroundings start to burn. The response time of the vigorous deposit electric conduction is short, however, it may melt the materials of the plug and socket which may easily lead to the short-circuit of the wires in the long term. Consequently, it is important to clean the plug and socket regularly and coordinate with effective warning as well as protecting device for secure and safe life.The results of this research could serve as references for the design as well as the manufacturing-related protection installment for the industry in order to not only set up the accurate methods to prevent from deposit electric conduction but also correct the habits of using the electrical appliances.
