树脂灌封电力电子电容器耐湿热性能的研究
|
摘要
通过对树脂灌封的电力电子电容器灌封材料改性,提高环氧树脂阻隔性和与其他材料的结合力,同时对电容器的结构设计进行改进,减少水汽侵入,解决其在风能光伏等领域使用中的耐湿热问题。通过湿热耐久性试验和长时湿热耐久试验对改进后的电容器进行试验验证。改进后的电容器通过长时湿热耐久性试验,保证圆柱形电力电子电容器在严酷的环境中安全可靠地运行。
The barrier properties of epoxy resin and its bonding with other materials is improved by changing the performance of resin-encapsulated power electronic capacitor materials. At the same time,the improvement of the structural design of the capacitor reduces penetration of water vapor and solves the problem of heat and humidity resistance of the capacitor in the field of wind energy photovoltaic and the like. The test verification of the modified capacitor is performed by the damp heat durability test and the long-term damp heat endurance test. The improved capacitors passing the long-term damp heat durability test can assure safe and reliable operation of cylindrical power electric capacitor at severe environment.
