Title:
GAS-INSULATED ELECTRIC APPARATUS AND MANUFACTURING METHOD FOR GAS-INSULATED ELECTRIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/012012
Kind Code:
A1
Abstract:
This gas-insulated electric apparatus is provided with: a metallic airtight container (2); a high voltage conductor (3) which is housed in the airtight container (2) and to which voltage is applied; an insulative support member (4) which insulates and supports the high voltage conductor (3) relative to the airtight container (2); and a non-linear resistive film (6) which covers at least a portion, of an inner surface of the airtight container (2), under the high voltage conductor (3). The non-linear resistive film (6) is formed by dispersing non-linear resistive material particles into an insulation material. The non-linear resistive material particles are disposed in the insulation material such that at least one of the non-linear resistive material particles is always in contact with conductive foreign substance mixed in the airtight container (2).
