Title:
A manufacturing method of a gas insulation electric appliance and a gas insulation electric appliance
Document Type and Number:
Japanese Patent JP6246363
Kind Code:
B2
Abstract:
The present invention is provided to comprise: a container filled with insulating gas; a high voltage conductor (3) arranged inside the container and applied with a prescribed voltage; and an insulating support member configured to insulate and support the high voltage conductor (3) relative to the container. The high voltage conductor (3) is covered by a first dielectric film (6). The first dielectric film (6) has a first main surface (6A) exposed inside the container, and a second main surface (6B) located on a side opposite to the first main surface (6A) and being in contact with the high voltage conductor (3). The first dielectric film (6) is provided with a through hole (6H) extending from the first main surface (6A) to the second main surface (6B). The through hole (6H) has an inner circumferential surface on which a first coating film (7) is formed such that at least a hole diameter of the through hole (6H) is less than a diameter of an electron avalanche in a state where a gas insulated electrical apparatus is used.
