Abstract

The utility model discloses a long-life reproducible fuse, which is used for improving the working stability of fuses and prolonging the service life. The technical scheme is that: the long-life reproducible fuse comprises an insulating casing, a fuse wire and tube caps, wherein the fuse wire is arranged in the insulating casing, the tube caps are fixedly mounted at two ends of the insulating casing; and the long-life reproducible fuse is characterized in that a bonding layer and a clay adsorption layer are additionally added, and the clay adsorption layer is bonded on the inwall of the insulating casing by the bonding layer. The long-life reproducible fuse has the main advantages as follows: 1, the inner layer of the insulating casing is the clay adsorption layer which has the functions of adsorbing water vapor and oxygen, the working environment of the fuse wire and other components is improved, and the working stability of the fuse is promoted; 2, moreover, a plurality of sub-layers are formed by the clay adsorption layer through the layer-by-layer pressing process, the innermost layer of the clay adsorption layer can be scraped away in case of the situation that the fuse wire is attached to the inwall, and the fuse wire is replaced with a new one, thereby greatly prolonging the service life of the fuse.

Description

Renewable fuse of a kind of long-life
Technical field
The fuse that the utility model relates to a kind of electric elements, particularly stable work in work and can increase the service life belongs to the electric elements technical field.
Background technology
Fuse is a kind of short-circuit protector commonly used, is widely used in distribution system and control system, mainly carries out short-circuit protection and overload protection.The structure of fuse comprises insulation shell, be arranged in the fuse of insulation shell and be positioned at the pipe cap at insulation shell two ends.During use, fuse is serially connected with in the protected circuit, and when circuit was short-circuited fault, fuse was divided deenergizing by instantaneous fusing, plays a protective role.The shell of fuse adopts ceramic material mostly at present, has the good insulation performance performance, but lacks the adsorption function to steam and oxygen, makes the fuse that is enclosed in the insulation shell easily produce surface oxidation, thereby causes fuse insulation less stable.In addition, when fuse during by big current fusing, electric arc splashes fuse or fuse particle and is bonded in firmly on the inwall of insulation shell, is difficult to remove, and causes fuse to be scrapped.Moreover, using a large amount of insulators at power circuit, the insulator use reaches 20 years and will be updated replacement, though these insulators can not continue to use at high-tension line, but it is superior that its electrical insulation capability still belongs to, large quantities of insulators that change do not have suitable recycling approach, cause waste on the one hand, form environmental pollution on the other hand yet.
The utility model content
The purpose of this utility model be at prior art drawback, renewable fuse of a kind of long-life is provided, described fuse can effectively utilize discarded insulator, and can prolong its useful life by the setting of layer structure.
Problem described in the utility model realizes with following technical proposals:
Renewable fuse of a kind of long-life, it comprises insulation shell, fuse and pipe cap, described fuse is positioned at insulation shell, pipe cap is packed in the insulation shell two ends, its special feature is, sets up tack coat and clay adsorption layer, and described tack coat is bonded in the clay adsorption layer on the insulation shell inwall.
Renewable fuse of above-mentioned long-life, set up regeneration insulator powder neutralizing layer, described regeneration insulator powder neutralizing layer and is bonded together by will regenerate insulator powder neutralizing layer and insulation shell inwall of tack coat between insulation shell inwall and clay adsorption layer.
Renewable fuse of above-mentioned long-life, described clay adsorption layer is made of a plurality of layerings of mutual bonding.
Renewable fuse of above-mentioned long-life, described clay adsorption layer comprises 3~5 layerings.
The utility model improves with raising problem in useful life at improving the fuse job stability, its major advantage is as follows: 1. the insulation shell of fuse adopts layer structure, the internal layer of insulation shell is the clay adsorption layer, the clay adsorption layer has the adsorption function to steam and oxygen, improve the operational environment of fuse and other elements, improved the stability of fuse device work; 2. the clay adsorption layer forms a plurality of layerings by pressing process successively, in case the situation that fuse is attached to inwall occurs, the most inboard layering that can strike off the clay adsorption layer more renews fuse again, prolongs the service life of fuse greatly; 3, the internal layer of insulation shell is regeneration insulator powder neutralizing layer, and this layer is crushed to powder with the waste old ceramics insulator, makes by tablet forming technique, when keeping good insulation performance and support function, realize twice laid, reduce the fuse production cost, and be conducive to environmental protection.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged view at Figure 1A place.
Each list of reference numerals is among the figure: 1, fuse, 2, pipe cap, 3, regeneration insulator powder neutralizing layer, 4, tack coat, 5, the clay adsorption layer, 5-1, layering, 6, insulation shell.
Embodiment
Referring to Fig. 1, the utility model comprises insulation shell, fuse 1 and pipe cap 2, and fuse is positioned at insulation shell, and pipe cap is packed in the insulation shell two ends.Insulation shell of the present utility model is layer structure, described layer structure is respectively insulation shell 6, regeneration insulator powder neutralizing layer 3, tack coat 4 and clay adsorption layer 5 from outside to inside, bondd and is integrated admittedly by will regenerate insulator powder neutralizing layer and clay adsorption layer of tack coat.Regeneration insulator powder neutralizing layer 3 is raw material with the insulator of discarding, and will discard insulator and be broken for powder, makes by tablet forming technique.By adhering to regeneration insulator powder neutralizing layer, can make the fuse that has fused be able to housing regeneration.Regeneration insulator powder neutralizing layer has the good insulation performance performance, and can guarantee the insulation property of insulation shell.The inwall of insulation shell is clay adsorption layer 5, and the raw material of clay adsorption layer is clay desiccant, the function that the clay adsorption layer has good suction, keeps dry, and it is not yielding, for fuse provides the environment of a drying, and then prevent the fuse oxidation, improve the job stability of fuse greatly.
Referring to Fig. 2, clay adsorption layer 5 adopts pressing process preparation successively, and it is made of a plurality of layering 5-1 of mutual bonding, and the number of layering is 3~5.This structure be when in case the situation that fuse failure is attached to inwall occur, can strike off in the clay adsorption layer near that layering of fuse, and more renewing fuse continues to use, and this measure can prolong the service life of fuse.
