摘　　要：采用正交设计方法,对中压大容量液体钽电解电容器工作电解质的配方进行了优化设计,研究了2种去极化剂对电容器性能的影响,试验结果表明,酸度对工作电解质的电导率和沸点有显著影响,在工作电解质中适量添加去极化剂,能有效地改善电容器的高低温性能。利用所研制的2种工作电解质浸渍装配成100V/100μF 的液钽电容器,测试结果表明,电容器各项电性能良好。The compounding formula of working electrolyte solution for medium voltage,large capacitance wet tanta- lum capacitor is optimally designed.The influence of depolarizer on capacitor's property is studied.The experiment results show that acid content has notable influence on the conductance and the boiling point of working electrolyte solution.The high and low temperature performance of capacitor can be improved by adding a proper volume of depolarizer into working electro- lyte.The electrolytes developed in this experiment are used to dip and assemble 100V/100μF capacitors.The electric test re- suits of the capacitors are perfect.
