Abstract
The utility model discloses a high-voltage tubular fuse and belongs to the technical field of fuses. The fuse comprises an insulating shell, end electrodes positioned at two ends of the insulating shell and a metal thin sheet positioned inside the insulating shell; two ends of the metal thin sheet are connected with the end electrodes at the two ends of the insulating shell respectively through by soldering tin; a plurality of long circular holes are evenly distributed on the metal thin sheet; and with the long circular holes distributed on the metal thin sheet, elongated fusing portions can be formed on the metal thin sheet. The high-voltage tubular fuse of the utility model can be used in a high-voltage circuit, and can cut off the circuit with safety when faults occur on the circuit.
Description
Technical field
The utility model relates to a kind of high pressure tube fuse, belongs to the fuse technical field.
Background technology
Fuse is also referred to as fuse, and it is a kind of being arranged in circuit, guarantees the electric elements of circuit safety operation.When circuit broke down or be abnormal, the electric current of rising likely damaged some important devices in circuit, even also likely burns circuit and causes fire.If fuse correctly has been installed in circuit, so, after electric current was elevated to certain numerical value, fuse can be by the mode from fusing by circuitry cuts, thereby plays the effect of protective circuit safe operation.
The shape of fuse and size are different, divide according to the shape of fuse, can be divided into tube fuse, blade fuse, cutting knife type fuse, spiral fuse and flat fuse etc.Volume according to fuse divides, and can be divided into large-scale fuse, medium-sized fuse, minitype fuse and microfuze.
At present, popular tube fuse adopts fuse as melt usually on the market, the voltage max that this fuse generally can bear is 250V, if it is arranged in the circuit that voltage is higher, due to overtension, fuse insulation shell when fusing is inner can produce the electric arc that is difficult for extinguishing, and this electric arc can make the temperature of insulation shell inside and air pressure sharply raise, and likely causes blast.
The utility model content
The utility model, for the problem in background technology, proposes a kind of high pressure tube fuse, and this fuse can safety fusing under condition of high voltage.
The utility model, for solving above technical problem, adopts following technical scheme:
A kind of high pressure tube fuse, the sheet metal that comprises insulation shell, is positioned at the termination electrode at insulation shell two ends and is positioned at insulation shell inside; The two ends of described sheet metal are connected with the termination electrode at insulation shell two ends by scolding tin respectively; On described sheet metal, be uniform-distribution with several slotted holes, these slotted holes make on sheet metal to have formed a lot of long and narrow fusing sections.
As further prioritization scheme of the present utility model, described insulation shell adopts flame-retardant insulating material to make.
Technique effect:
1, the utility model can be applied in high-tension circuit, safety by circuitry cuts when circuit breaks down.
2, design is ingenious, is easy to processing, has stronger practicality.
3, insulation shell adopts flame-retardant insulating material to make, and has fail safe preferably.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure title: 1, termination electrode; 2, insulation shell; 3, sheet metal; 4, scolding tin; 5, slotted hole; 6, fusing section.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, the sheet metal 3 that comprises insulation shell 2, is positioned at the termination electrode 1 at insulation shell 2 two ends and is positioned at insulation shell 2 inside; The two ends of described sheet metal 3 are connected with the termination electrode 1 at insulation shell 2 two ends by scolding tin 4 respectively; Described insulation shell 2 adopts flame-retardant insulating material to make; On described sheet metal 3, be uniform-distribution with several slotted holes 5, these slotted holes 5 make on sheet metal 3 to have formed a lot of long and narrow fusing sections 6, and when circuit broke down, the fusing simultaneously of these fusing sections 6, by circuitry cuts.In the process of fusing, electric arc can be divided into a plurality of segments and extinguish fast.
During use, this fuse is contained in the circuit needed protection, when circuit breaks down; electric current by sheet metal 3 increases, and the temperature of sheet metal 3 rises, and after temperature rises to certain numerical value; the fusing simultaneously of fusing section 6 on sheet metal 3, by circuitry cuts.In the process of fusing, electric arc can be divided into a plurality of segments and extinguish fast.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
