Title:
ELECTRIC-POWER-FEEDING DEVICE AND PLASMA GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057453
Kind Code:
A1
Abstract:
This electric-power-feeding device comprises a plurality of electrical circuit parts, a shield part, an outer-side sheath part, and an inner-side sheath part. The plurality of electrical circuit parts are members provided to the radial-direction center side of an electric power cable that feeds supplied electric power supplied from a power source device to a plasma head for generating plasma, the plurality of electrical circuit parts feeding the supplied electric power. The shield part is an electroconductive member provided farther to the radial-direction outer side of the electric power cable than the plurality of electrical circuit parts so as to cover the plurality of electrical circuit parts, the shield part electrically shielding the plurality of electrical circuit parts from an external environment. The outer-side sheath part is an insulating member provided farther to the radial-direction outer side of the electric power cable than the shield part so as to cover the shield part, the outer-side sheath part physically protecting the shield part from the external environment. The inner-side sheath part is an insulating member provided farther to the radial-direction inner side of the electric power cable than the shield part, the inner-side sheath part providing support so as to sandwich the shield part in concert with the outer-side sheath part.
