| Zusammenfassung: | The invention relates to the field of manufacturing of coupling capacitor and capacitor voltage transformer for an electric power system, and discloses a novel hidden foil-type capacitor element. The capacitor element comprises a positive plate aluminum foil, a negative plate aluminum foil and an insulating medium, and is characterized in that: both sides of the positive and negative plate aluminum foils are retracted into the edge of the insulating medium; and the wound ends of the positive and negative plate aluminum foils are exposed on the upper side and the lower side of the large surface of a flattened capacitor element respectively to form a positive electrode and a negative electrode of the capacitor element. |
