Title:
VACUUM-CAPACITOR-TYPE VOLTAGE TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2022/049891
Kind Code:
A1
Abstract:
The present invention comprises a vacuum capacitor (2) that constitutes a main capacitor (or a part of a main capacitor), and a voltage-dividing capacitor, a configuration being attained with which it is possible to perform a desired voltage measurement using the voltage division of the vacuum capacitor (2) and the voltage-dividing capacitor. In the vacuum capacitor (2), an insulated tube opening (4a) on one side in the axial center direction of an insulated tube (4) is closed by a high-voltage part (5), and the insulated tube opening (4b) on the other side in the axial center direction is closed by a ground part (6), and a vacuum container (20) is constituted. A voltage division part (8) is insulated and supported, by a tubular insulating support part (7) extended in the axial center direction, in a position facing the high-voltage part (5) on the inner side of the vacuum container (20) at the ground part (6). The high-voltage part (5), ground part (6), and voltage-division part (8) of the vacuum capacitor (2) are thereby insulated from each other, and the outer circumferential side of the voltage-division part (8) is covered by the high-voltage part (5) and the ground part (6).
