Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a fuse insulating cylinder for solid insulated ring network cabinets, which can solve the problem that the fuse insulating cylinder used in the existing solid insulated ring network cabinets is exposed to the conductors connected to the two ends of the fuse pipe, and the surface of the conductor is exposed. There will be defects such as pollution, oxidation, rust, etc., which will affect the breaking performance of the fuse and cause the problem of hidden danger of insulation

Disclosed in the invention is a fuse insulating cylinder for a solid insulating ring main unit. The fuse insulating cylinder comprises an insulating cylinder body; and an inlet wire conductor and an outlet wire conductor are arranged on the insulating cylinder body, wherein the conductors are connected with a fusion tube respectively. Besides, an inlet wire casing tube, an outlet wire casing tube, and a ground casing tube are respectively arranged on the insulating cylinder; the inlet wire conductor is arranged in the inlet wire casing tube; and the outlet wire conductor is arranged in the outlet wire casing tube. Because the conductors connected with the fusion tube are arranged in the inlet wire casing tube and the outlet wire casing tube, defects of frequent occurrence of foul, oxidization, and rustiness and the like for long time can be overcome; the breaking performance of the fuse can be protected from being influenced; and the potential insulation hazard can be avoided.
Description
technical field [0001] The invention relates to the field of fuses, in particular to a fuse insulation cylinder for a solid insulation ring network cabinet. Background technique [0002] The solid insulated ring network cabinet is a very important switch device in the power distribution system, especially in the urban power distribution system. It has the advantages of small size, high reliability, and environmental protection. The fuse fuse used in the insulated ring network cabinet is installed in the insulating cylinder. The conductors connected between the insulating cylinder and the two ends of the fuse tube are exposed in the solid insulated ring network cabinet. After a long period of operation, the conductor surface will be polluted, oxidized, and rusted. These defects will not only affect the breaking performance of the fuse, but also have hidden dangers in insulation. In the case of overvoltage, it will cause insulation failure, and in severe cases, it will cause t...
