Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a capacitor vacuum impregnation device. Background Art

[0002] A capacitor is a kind of electronic component, which consists of two conductor plates (usually metal plates) and an insulating material (dielectric) in the middle. When a voltage is applied between these two conductor plates, charges will accumulate on the conductor plates, forming an electric field, thereby storing energy. The core characteristic of a capacitor is its ability to store and release charges, which makes it play a crucial role in electronic circuits. The main function of a capacitor vacuum impregnation device is to impregnate capacitors in a vacuum environment. This process helps to remove air and other impurities inside the capacitors, ensuring that the impregnation material (such as insulating oil or other liquid insulating materials) can fully penetrate into all parts of the capacitors, thereby improving their overall insulation ability and long-term stability.

[0003] Some capacitor vacuum impregnation devices may have problems with poor sealing, which will cause it difficult to completely remove gas and moisture during the impregnation process, affecting the insulation performance and long-term stability of the capacitors. And during the impregnation process, if it is necessary to supplement the impregnation liquid, the current devices often need to stop the machine to add liquid.
