- DRY TYPE PLUG-IN BUSHING MUNUFACTURING METHOD THEREOF AND HIGH-VOLTAGE INSTALLATION HAVING A BUSHING SUCH AS THIS

摘要

The present invention relates to a dry plug-in bushing and a manufacturing method, and to a high voltage facility, and more particularly, to a plug-in high voltage bushing for connecting an external electrical conductor to a high voltage facility filled with an insulator, and a high voltage facility including the bushing. About. The dry plug-in bushing according to the present invention comprises: a centrally located conductor; A cast resin insulator that is cast-molded in a shape surrounding the outer periphery of the conductor; An electric field control electrode made of a semiconductive synthetic resin material coupled to the upper end of the lower support and used as an electrode for controlling an electric field; A lower support bracket connected to the lower outer periphery of the cast resin insulator; An injection insulator manufactured by insert injection including the outer periphery of the cast-type resin insulator and the electric field control electrode and having a plurality of shades formed to secure an insulation leakage distance; And a stress cone connected to the lower end of the cast resin insulator and in which an insulating material and a semiconducting material are combined.
