Abstract

The invention provides a fuse carrier and a manufacturing method of the fuse carrier. The fuse carrier comprises a fusion tube, wherein the inner wall of the fusion tube is provided with an arc extinguishing layer; the number of the connecting pipes is two, the two ends of the fusion tube are connected with the two connecting pipes respectively, the interiors of the connecting pipes are communicated with the interior of the fusion tube, and the connecting pipes are of variable-diameter structures; the circumferential outer surface of the fusion tube and the circumferential outer surface of the connecting tube are respectively provided with a protective layer. According to the invention, the problem of poor use performance of the fuse carrier in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a fuse-carrying part of a fuse and a method for manufacturing the fuse-carrying part of the fuse. Background technique [0002] The enclosed fuse is a protective device for overload and short circuit in the power system. It has the characteristics of convenient operation, strong adaptability to outdoor environments, and no metal exposure in the shell. It is used in the primary side of distribution lines and distribution transformers as protection and protection. It is used for equipment throwing and cutting operations. A common enclosed fuse consists of a fuse-carrying part with a fuse and a housing. The housing includes a porcelain sleeve, upper and lower insulated leads, upper and lower static contacts, a sealing cover and a fixed hoop; and the fuse-carrying part is made of It consists of a fuse tube, an upper fuse cap, upper and lower connecting fittings and a spring slider....
