Abstract
The utility model discloses a solid insulation looped netowrk is fuse insulating cylinder for cabinet, including insulating barrel, be equipped with the inlet wire conductor of connecting the fusion tube respectively and the conductor of being qualified for the next round of competitions on the insulating barrel, be equipped with entrance bushing on the insulating cylinder respectively, go out wire sleeve and grounding sleeve, the inlet wire conductor sets up in entrance bushing, the conductor of being qualified for the next round of competitions sets up in a wire sleeve. The conductor of connecting the fusion tube sets up in advancing, goes out wire sleeve, defect such as avoid for a long time that filth, oxidation appear in the operation, rust, ensure the fuse to cut -off the performance not influenced, avoid appearance insulation hidden danger.
Description
Technical field
The utility model relates to fuse field, is specifically related to a kind of solid insulation ring main unit fuse insulating cylinder.
Background technology
Solid insulation ring main unit is a very important switching device in distribution system, particularly city electric distribution system, and have the advantages such as volume is little, reliability is high, environmental protection, fuse is the critical component on solid insulation ring main unit; The fuse fusion tube used in current solid insulation ring main unit is arranged in insulating cylinder, the conductor that insulating cylinder is connected with fusion tube two ends is exposed in solid insulation ring main unit, through long-play, conductive surface has filth, be oxidized, the defect such as to get rusty, these defects constantly accumulate, and not only can affect the break performance of fuse, also there is insulation hidden danger, can cause insulation fault in the superpotential situation of appearance, serious meeting causes ring main unit blast, large-area power failure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of solid insulation ring main unit fuse insulating cylinder, the conductor that the fuse insulating cylinder that uses in existing solid insulation ring main unit is connected with fusion tube two ends can be solved exposed, conductive surface has filth, be oxidized, the defect such as to get rusty, cause the break performance affecting fuse, there is the problem of insulation hidden danger.
The utility model is achieved through the following technical solutions:
A kind of solid insulation ring main unit fuse insulating cylinder, comprise insulating cylinder body, described insulating cylinder body is provided with the inlet wire conductor and outlet conductor that connect fusion tube respectively, described insulating cylinder is respectively equipped with entrance bushing, outlet casing tube and grounding sleeve, described inlet wire conductor is arranged in entrance bushing, and described outlet conductor is arranged in outlet casing tube.
Further scheme of the present utility model is also provided with the voltage sensor being connected to outlet conductor in described outlet casing tube.
Further scheme of the present utility model is, described voltage sensor is the coil be wrapped on outlet conductor.
Further scheme of the present utility model is, described insulating cylinder outer wall is also provided with conductive layer.
The utility model advantage is compared with prior art:
One, the conductor connecting fusion tube is arranged at into and out of thread casing, and defects such as avoiding long-play to occur filth, be oxidized, get rusty, guarantees that the break performance of fuse is unaffected, avoid occurring insulation hidden danger;
Two, voltage sensor is convenient to the voltage signal of monitoring fusion tube, is convenient to fix a breakdown in time;
Three, conductive layer makes insulating cylinder outer wall form the equipotential of ground connection, even if having spot, water also there will not be electrical leakage problems, increases the fail safe of attendant's work, improves the reliability under the antifouling capacity of fuse, insulation property and long-time running further.
