摘　　要：针对不同贮存环境对高压脉冲电容器电容量漂移的影响进行了长期对比实验研究。采用同一批次同一型号高压脉冲电容器,随机抽取组合成实验对比组。通过观测,发现该型号高压脉冲电容器电容量的漂移与贮存环境温度的关系密切;与自然光照的关系并不明显;在同样的贮存环境下,与未加任何保护的实验对比组相比较,使用硅胶灌注的实验对比组电容量的漂移速度明显平缓,特别在贮存环境温度较低时,硅胶灌注对高压脉冲电容器电容量的漂移有明显的减缓作用。The experiment being made by our research group is aimed at obtaining the result of the capacitance variability of high voltage pulse capacitor. The quality of all the products we used in this experiment is nearly same. All the products were grouped at random. The result of this experiment indicated that the capacitance variability dependent on the temperature specially, while the effect of illumination is limited. Compared to the products protected by silica gel, the capacitance of the products without any screen increased sharply inch by inch, while the capacitance of the product protected by silica gel increased slowly, especially in the low temperature.
