中文摘要 | 本研究主要在於探討以乙二醇與水爲系統之電解液中,分別添加磷酸二氫銨 (ammonium dihydrogen phosphate)、己二酸胺(ammonium adipate)、甲酸胺(ammonium formate)及對硝基苯甲酸胺(p-nitrobenzoic ammonium formate)等有機與無機胺鹽對於鋁質電解電容器中之電導度、酸鹼值、火花電壓、低溫穩定性及壽命測試過程中之電容量、捐失角及漏電流之變化情形。由實驗結果證明,添加磷酸二氫胺在乙二醇雨水系統電解液中有助於火花電壓的提昇。添加甲酸胺有助於增加溶液導電度。己二酸胺則有助於穩定氧化膜的生成。而對硝基苯甲酸胺則有防止電解電容器之內爆情形産生。最佳條件爲添加0.6%磷酸二氫胺,5.5%己二酸胺,14.9%甲酸胺及0.77%對硝基苯甲酸胺。溶液之導電度爲18.60 mS.cm¯¹,pH值爲6.37,火花電壓爲120V,於273K低溫穩定性佳,高溫負荷之壽命測試增加至1344小時。 |
英文摘要 | This study examined the effects of organic and inorganic ammonium salts in the electrolyte of an aluminum electrolytic capacitor on the performance of the electrolyte in terms of conductivity , pH, and sparking voltage. In addition, the capacity (Cp), dissipation factor (DF), and leakage current (LC) of capacitors impregnated with electrolytes prepared in this work were periodically measured under loading at high temperatures. The results revealed that the sparking voltage increased quickly in the presence of ammonium dihydrogen phosphate, the conductivity of the electrolyte was promoted by adding ammonium formate as electrolyte, and the oxide film at the surface of aluminum was more stable in the presence of ammonium adipate. Further, the p-nitrobenzoic ammonium formate functioned was hydrogen adsorption reagent. The optimum operating conditions for this system were 0.6% added ammonium dihydrogen phosphate, 5.5% added ammonium adiapate, 14.9% added ammonium formate, and 0.77% added p-nitrobenzoic ammonium formate. The properties of this ethylene glycol/H₂O solution were 18.60 mS.cm¯¹ conductivity, pH 6.37, and sparking voltage 120 V. The results showed that the durability of the aluminum electrolytic capacitor increased to over 1344 h. |
