Problems solved by technology

Since the insulating cylinder is directly wound on the outer surface of the two conductive rings and the mounting base, their connection may cause leakage, and the positioning of the two conductive rings and the mounting base in the insulating cylinder is not firm enough
In addition, the connection strength between the insulating cylinder of this structure and the two conductive rings and the installation base is not high enough, so that the bending resistance of the base is also low

Abstract

The invention discloses a base for an oil-immersed fuse, which comprises an insulation cylinder body, a head conducting ring, a middle conducting ring and a mounting pedestal. The insulation cylinder body comprises an inner layer insulation cylinder and an outer layer insulation cylinder, wherein the inner layer insulation cylinder comprises an interphase insulation cylinder and a mounting insulation cylinder that are defined and wound by epoxy glass fibers. Seal rings are arranged between the outer surface of the rear part of the head conducting ring and the inner surface of the interphase insulation cylinder, between the outer surface of the front part of the middle conducting ring and the inner surface of the interphase insulation cylinder, between the outer surface of the rear part of the middle conducting ring and the inner surface of the mounting insulation cylinder, and between the outer surface of the mounting insulation cylinder and the inner surface of the mounting pedestal respectively; sealants are arranged between the outer surface of the head conducting ring and a front port of the interphase insulation cylinder, between the outer surface of the middle conducting ring and a rear port of the interphase insulation cylinder, between the outer surface of the middle conducting ring and a front port of the mounting insulation cylinder, and between the outer surface of the mounting insulation cylinder and a front port of the mounting pedestal respectively; and the outer layer insulation cylinder is in an integral structure defined and wound by the epoxy glass fibers.

Description

technical field [0001] The invention relates to a multi-seal base for an oil-immersed fuse. Background technique [0002] Oil-immersed fuses are installed on oil-immersed box-type transformers. Generally, oil-immersed fuses include a cylindrical base with one-way opening, a fuse and a fuse. At the installation base at the end of the insulation cylinder, the insulation cylinder is formed by winding epoxy glass fiber reinforced composite insulation material, and two conductive rings and an installation base are connected as a whole to form a closed base. Since the insulating cylinder is directly wound on the outer surfaces of the two conductive rings and the mounting base, leakage may occur at their connection, and the positioning of the two conductive rings and the mounting base in the insulating cylinder is not firm enough. In addition, the connection strength between the insulating cylinder of this structure and the two conductive rings and the installation base is not hi...
