Description
Technical field
The invention belongs to the fuse technical field, relate to a kind of transparent fuse switch.
Background technology
The shell of existing fuse or claim that fusion tube is a ceramic material, be with the potter's clay sintering form, technology is wayward, the scrappage height, the quality instability, frangible, often ftracture when doing the fuse attribute testing.Because sintering technology, mineral resources, ring are competed the restriction of factors such as polluting, ceramic fuse only has minority specialty ceramics factory to produce at present, and the cost of fuse manufacturer is higher, the numerous rope of technology, production cycle is long, does not supply when producing the busy season, is one of bottleneck of restriction fuse development.
When electric power maintenance, often run into the problem that fuse switch fuses because of electric current is excessive, ideally, after fuse switch blows, can fall, thereby cut off the protective effect of circuit realization equipment from link.In actual applications, because fuse switch is in the environment of exposure, stand wind, Exposure to Sunlight for a long time and drench with rain, make the Plug Division of fuse switch suffer oxidative attack and save bit by bit a large amount of dusts, cause the success rate of fuse switch when falling to reduce greatly, so that when outage is repaired, be difficult to whether fall the damage of judging fuse switch from fuse switch, cause trouble to the attendant, wasted preventive maintenance time.
Chinese patent 200910156807.3, a kind of fuse shell.This inventive features is that housing adopts BMC to make.BMC is also referred to as the unsaturated polyester (UP) BMC, BMC (DMC) material, and wherein BMC (DMC) material is the abbreviation of Bulk (Dough) molding compounds, so two kinds of addresses of BMC/DMC are arranged both at home and abroad.Its primary raw material is by GF (short glass fiber), UP (unsaturated-resin), MD (filler) and the various additive material bulk prepreg through fully mixing.The DMC BMC has good electric property, mechanical performance, and thermal endurance, chemical resistance adapts to various moulding processs again, can satisfy various products to performance demands.Substitute pottery with DMC, advantage is at first to make suitable mould, DMC material system is put into the mould compacting to form, it is extremely easy to make, general individual or little factory just can the mold pressing production in enormous quantities, and precision height, cost are low, and can mold pressing nameplate or laser marking, Expected Results can be reached through the long term test checking, and the under-supply and unsettled bottleneck of quality of the long-standing fusion tube of fuse industry can be fundamentally solved.Also the injection molding machine injection moulding can be used for the shell that electric current is little, identical technique effect can be reached.But, as ceramic fuse, be difficult to whether fall the damage of judging fuse switch from fuse switch, cause trouble to the attendant, the waste preventive maintenance time.
Chinese patent 200910216957.9, a kind of fuse.This utility model discloses the structure of fuse, comprise the hollow cartridge fuse, the upper end of cartridge fuse is equipped with upper fixing element, the lower end of cartridge fuse is provided with down fixture, is hinged with the fuse fixed mount on the following fixture, is provided with fuse in the cartridge fuse, the upper end of fuse is electrically connected with upper fixing element, the lower end of fuse is electrically connected with the fuse fixed mount, and its design feature is: the lower end of cartridge fuse is installed with one section transparent secondary cartridge fuse, and the lower end of secondary cartridge fuse is fixed together with following fixture.Under the electricity consumption normal condition, when fuse does not also fuse, just can see that by transparent secondary cartridge fuse the fuse heavily fortified point directly strains in cartridge fuse, break down and work as electricity consumption, when actual current surpasses fuse permission electric current, fuse fuses high temperature, the fuse part of below, fuse failure place this moment will be in cartridge fuse blows out cartridge fuse under the impact of high temperature gas flow, this moment is when observing by secondary cartridge fuse, in the secondary cartridge fuse will be empty, can judge fast whether fuse fuses, especially be suitable as fuse switch and use, can make the attendant under the situation of not climbing, judge whether to need to change fuse fast.But this utility model is owing to establish two sections cartridge fuses of major-minor, and complex structure also increases difficulty to processing and manufacturing.
Chinese patent 200810160209.9, fuse switch.This fuse switch is to have insulator, fusion tube, go up moving contact, load electrode, arc control device and binding post, and the upper end of described arc control device is provided with high-field electrode graphitic carbon block, in graphitic carbon block upper end lead-in wire is set and is connected with binding post.Described graphitic carbon block is the composite material of graphite and copper powder.But, be difficult to judge whether to damage from fuse switch, cause trouble to the attendant, the waste preventive maintenance time.
Chinese patent 200810158614.7, fuse switch.This fuse switch has fusion tube, it is characterized in that: the fusion tube upper end is provided with the movable contact headstock, installs moving contact in the last movable contact headstock; The lower end of fusion tube is provided with double hook and falls supporter, falls the middle lower moving contact seat that is provided with of supporter, and lower moving contact is installed in the lower moving contact seat.Described upward moving contact and lower moving contact are copper soft round body, and the described supporter that falls is the stainless steel stamping parts.Described going up in movable contact headstock and the lower moving contact seat is provided with antagonistic spring, and last moving contact and lower moving contact are copper round flexible conductor with the lead that is connected of terminal.This fuse switch is because last moving contact and lower moving contact are copper soft round body, and modification causes loose contact easily, is that fusion tube is opaque in addition, is difficult to judge whether to damage from fuse switch, causes trouble to the attendant, the waste preventive maintenance time.
Chinese patent 200620139626.1, the outdoor AC high-voltage expulsion fuse.Fixing respectively up and down gold utensil and the following gold utensil gone up of the porcelain vase of this fuse, fixing static contact successively above the last gold utensil, the copper terminal block, canopy, the iron terminal block, dough is linked up with surely under the last gold utensil, fixing upper connecting terminal on copper terminal block and the iron terminal block, put spring between static contact and the canopy right part and connect and compose a locking device by rivet, fixing lower carriage successively below it, following terminal block and supporting bracket, fixing lower connecting terminal on following terminal block and the supporting bracket, fixing respectively ring and the following ring gone up of the upper and lower end parts of cartridge fuse, following seat is connected with following ring, the plate of sending out that has little spring is fixed on down on the seat, the fuse of band button is contained in the cartridge fuse and band button end is compressed by pressure releasing cap, fuse is fixed on down below the seat by a cartridge fuse and a process plate, fuse is in tension, following seat hangs in the lower carriage, and last ring leans against in the hook, and pressure releasing cap is locked by locking device below static contact.It has characteristics such as stable performance, long service life.This fuse is because last moving contact is copper, and modification causes loose contact easily, is that fusion tube is opaque in addition, is difficult to judge whether to damage from fuse switch, causes trouble to the attendant, the waste preventive maintenance time.
In sum, the insulator and the fusion tube of existing fuse are ceramic material, and technology is wayward during sintering, the scrappage height, and the quality instability, frangible, often ftracture when doing the fuse attribute testing.And because last moving contact is copper, modification causes loose contact easily, is that fusion tube is opaque in addition, is difficult to judge whether fuse damages, and causes trouble to the attendant, the waste preventive maintenance time.
