Title:
INSULATING SUPPORT DEVICE AND CIRCUIT USING THE INSULATING SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP3431412
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a switchgear, and simplify design by supporting a conductor by an embedded member, and penetrating the other conductor through an opening part.
SOLUTION: In a support insulator 10 as an insulating support device, a support electrode 11 to support a conductor is embedded in an upper part of an insulating layer 12, and installing bosses 13 are embedded in the grounding side of a lower part of the insulating layer 12. An opening part 14 is arranged in the insulating layer 12, and a cross-sectional shape of its opening is formed in an inverse U shape so as to open toward the grounding side. The opening part 14 is made penetrable. Therefore, the support insulator 10 is formed in a conductor penetrable shape, and a conductor can be penetrated through the opening part 14. When such an insulating support device is used in a compressed gas insulation switchgear, a design dimension is shortened.
