电力电容器真空干燥及压力浸渍工艺与设备的研究

Vacuum drying/pressure impregnating process and equipment for power capacitors

传统的电力电容器的生产工艺是将芯体元件卷绕后,先在真空干燥罐内进行加热和真空干燥,然后将芯体元件压装到电容器壳内,再在另一台真空压力浸渍罐内进行真空压力浸渍。一体式的真空干燥及真空压力浸渍工艺将上述两道工艺合二为一,在同一台真空罐内进行一体式的加热、真空干燥和真空压力浸渍。本文介绍了这一工艺的研究和设备的研制。

Conventionally the power capacitors were manufactured the way their wound cores should be heated and dried in a vacuum drying vessel first, and the cores should be pressed into capacitor shells, then all the unfinished capacitors were put into a vacuum pressure tank for inpregnation. To simplity and improve the tedious technological process, a new process is proposed to integrate well the heating and drying with impregnation in a vacuum tank. Introduces the R＆D of the new process and relevant equipment.
