Abstract
The utility model relates to a fuse and especially relates to a high-voltage fuse. The high-voltage fuse is characterized in that the high-voltage fuse is formed by moving contacts on two ends of a fusion tube and an electric conductor equipped with bidirectional pulling force in the fusion tube, the moving contacts and the electric conductor being connected by a lock catch joint. The high-voltage fuse has characteristics of a unique structure, stable performance, security and reliability, small size, light weight, free maintenance, long service life, low cut-off temperature, short arc extinguishing time, energy conservation and environment friendliness, simple manufacturing technique, easy use, and low production cost.
Description
Technical field
The utility model relates to a kind of fuse, especially relates to a kind of high-tension fuse.
Background technology
Fuse is one of protection electrical equipment the most frequently used between electrical network and the electric equipment, and is cheap and in advantages such as some scope of application protection are reliable because it is simple in structure although it is a kind of ancient protection electrical equipment, still is widely used so far.High-tension fuse commonly used mainly contains fuses such as falling injecting type, filling quartz sand and vacuum type at present; The molten part that these fuses use all is that alloy material is made, and the molten part that alloy material is made produces metal vapors when fusing is cut-off, cut-off the arc extinguishing difficulty; When falling expulsion fuse and cut-offfing arc extinguishing, there is metal vapors to spray to discharge and explosive sound is arranged, have potential safety hazard and contaminated environment.When the fuse of filling quartz sand cut-off arc extinguishing, because producing metal vapors, the arc extinguishing conditions such as the additional quartz sand of fusion tube domestic demand could extinguish arcs, and volume is large, weight is large, cost is high, unstable properties and the easy explosion of fusion tube.When the vacuum type fuse cut-offs arc extinguishing, because producing metal vapors, need the arc extinguishing condition ability extinguish arcs such as additional magnetic circuit, manufacture difficulty is large, cost is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned fuse and molten part produces the technological deficiencies such as metal vapors, arc extinguishing difficulty are large when cut-offfing arc extinguishing, a kind of structure uniqueness, stable performance are provided, safe and reliable, volume is little, lightweight, non-maintaining, life-span long, cut-off that temperature is low, the quenching time is short, energy-conserving and environment-protective, high-tension fuse that manufacturing process is simple, easy to use, cheap.
The utility model is realized in the following way:
A kind of high-tension fuse is characterized in that: it is to be assembled through the bayonet type node by the electric conductor that two-way tension is arranged in the moving contact at fusion tube two ends and the fusion tube to form;
Described electric conductor is to be assembled by anaerobic metallic conductor and anaerobic metal flexible conductor to form;
Described bayonet type node is to be assembled by metal electric heating electric conductor, metal button member and bimetallic thermo-sensitive conductive body to form;
Described bayonet type node is assembled by organic material fastener or organic material bolted by metal electric heating electric conductor and metallic conductor stack.
The utility model has following effect:
1) unique, the stable performance of structure: it is to be assembled through the bayonet type node by the electric conductor that two-way tension is arranged in the moving contact at fusion tube two ends and the fusion tube to form for the fuse that the utility model provides.
2) safe and reliable, the speed of cut-offfing is fast, easy to use, cheap: the fuse that the utility model provides, electric conductor that two-way tension is arranged and be connected with fusion tube two ends metal contact of installing in the fusion tube, a special bayonet type node is housed in the middle of the electric conductor, node combination in the current ration scope is tight, electric current passes through smoothly, when Node Current surpasses definite value or the following equipment of node, line failure, the heating of metal electric heating electric conductor, bimetallic thermo-sensitive conductive body and moving dropout of metal electric heating conduction body heat; Or the fusing of organic material fastener, bolt heat, metallic conductor and the dropout of metal electric heating electric conductor.The bayonet type node is opened under the two-way tension effect immediately, immediately disjunction of electric conductor in the fusion tube, this disjunction is not to melt the fusing of part but the contact separation of breaker type, molten part melts and the metal vapors of generation, so the electric arc ratio is easier to extinguish, electric arc extinguishes immediately when current over-zero in the fusion tubes such as vacuum or sulphur hexafluoride
3) volume little, lightweight non-maintaining, the life-span is long: the described electric conductor of the fuse that the utility model provides is to be assembled by anaerobic metallic conductor and anaerobic metal flexible conductor to form; Described bayonet type node is to be assembled by metal electric heating electric conductor, metal button member and bimetallic thermo-sensitive conductive body to form; Described bayonet type node is assembled by organic material fastener or organic material bolted by metal electric heating electric conductor and metallic conductor stack; Simple in structure, volume is little, lightweight, non-maintaining, the life-span is long, easy to use, cheap, the speed of cut-offfing is fast, energy-conserving and environment-protective.
