Title:
DRY-TYPE PLUG-IN BUSHING, MANUFACTURING METHOD OF SAME, AND HIGH-VOLTAGE INSTALLATION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/204363
Kind Code:
A1
Abstract:
The present invention relates to a dry-type plug-in bushing, a manufacturing method of same, and a high-voltage installation, and more specifically, to a plug-in high-voltage bushing for connecting an external electrical conductor to a high-voltage installation filled with an insulating body, and to a high-voltage installation comprising said bushing. According to the present invention, the dry-type plug-in bushing comprises: a conducting body positioned in the center thereof; a cast-type resin insulating body cast in a form surrounding the outer circumference of the conducting body; an electric field-control electrode made of a semiconducting synthetic resin material, coupled to an upper end of a lower support fitting, and used as an electrode for controlling an electric field; the lower support fitting connected to the outer circumference of a lower part of the cast-type resin insulating body; an injected insulating body produced by an insert injection including the outer circumference of the cast-type resin insulating body and the electric field-control electrode, and having formed thereon a plurality of fins for ensuring a leakage distance; and a stress cone connected to a lower end of the cast-type resin insulating body and having an insulating material and a semi-conducting material combined therein.
