A capacitor protection fuse, which includes a base, an anti-sway tube and a fuse tube, the base is provided with a first terminal, the lower end of the anti-sway tube is fixed on the base, and the inside of the anti-swing tube is provided with a pull Spring, the lower end of the extension spring is connected to the first terminal in the base, and the upper end of the extension spring is provided with a connection block; the upper end of the fuse tube is provided with a second terminal, and the fuse in the fuse tube is connected to the connection block. A tail wire is arranged between them; one end of the tail wire is connected to the fuse in the fuse tube, and the other end is fixedly connected to the connection block. The utility model not only can put away the tail wire after the fuse is blown, avoids the situation of power connection, and improves safety, but also has the advantages of simple and compact structure, low manufacturing cost and easy installation and use.
Description
Technical field
The utility model relates to a kind of fuse, specifically a kind of voltage capacitor protective fuse.
Background technology
Fuse is also referred to as fuse, and the IEC127 standard is defined as it " fuse-link fuse-link) ".It is a kind of being arranged in circuit, guarantees the electric elements of circuit safety operation.Fuse is exactly a kind of short-circuit protector in fact, is widely used in distribution system and control system, mainly carries out short-circuit protection or serious overload protection.
At present, in distribution system, in order to ensure capacitor safe, adopt fuse as overcurrent protection, be used for the disengagement failure capacitor, to guarantee the normal operation of fault-free capacitor.The fuse of existing fuse because of electric arc fusing after, the buttock line that fuse can be connected with fuse is by extracting out in cartridge fuse, to reach the effect of power-off protection.But, after existing fuse fuse failure, the buttock line be drawn out of is longer, buttock line easily contacts even electricity with equipment or conductive component on every side in swing process, causes the accident.
The utility model content
For above-mentioned deficiency, the utility model provides a kind of voltage capacitor protective fuse, thereby it can pack up buttock line the situation that occurs that company is electric of avoiding after fuse failure.
The technical scheme in the invention for solving the technical problem is: a kind of voltage capacitor protective fuse, it is characterized in that, comprise base, anti-swing pipe and cartridge fuse, be provided with the first binding post on described base, described anti-swing pipe lower end is fixed on base, described anti-swing pipe inside is provided with extension spring, and described extension spring lower end is connected with the first binding post in base, and the extension spring upper end is provided with contiguous block; Described cartridge fuse upper end is provided with the second binding post, between the fuse in described cartridge fuse and contiguous block, is provided with buttock line; Described buttock line one end is connected with the fuse in cartridge fuse, and the other end is fixedly connected with contiguous block.
Preferably, the vertical body of described anti-swing pipe for being made by insulating material.
Preferably, described cartridge fuse is obliquely installed.
The beneficial effects of the utility model are: after adopting said structure, the utility model is provided with extension spring and contiguous block in anti-swing pipe, after fuse failure, extension spring can drive in the anti-swing pipe of most of buttock line income by contiguous block, only there is extremely short buttock line to stay outside anti-swing pipe, thereby can effectively reduce the Probability that connects electric situation, improve fail safe.
The utility model not only can after fuse failure pack up buttock line, avoided occurring connecting electric situation, improved fail safe, but also has advantages of compactness simple for structure, cheap for manufacturing cost and install and use easy.
The accompanying drawing explanation
Structural representation when Fig. 1 is the utility model normal operation;
Fig. 2 is the structural representation after fuse failure in cartridge fuse described in the utility model;
In figure, 1 base, 2 anti-swing pipes, 3 cartridge fuses, 4 first binding posts, 5 extension springs, 6 contiguous blocks, 7 second binding posts, 8 buttock lines.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and, in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of voltage capacitor protective fuse of the present utility model, it comprises base 1, anti-swing pipe 2 and cartridge fuse 3, be provided with the first binding post 4 on described base 1, described anti-swing pipe 2 lower ends are fixed on base 1, the vertical body of described anti-swing pipe 2 for being made by insulating material, and its inside is provided with extension spring 5, described extension spring 5 lower ends are connected with the first binding post 4 in base, and extension spring 5 upper ends are provided with contiguous block 6; Described cartridge fuse 3 is obliquely installed, and upper end is provided with the second binding post 7, between the fuse in described cartridge fuse 3 and contiguous block 6, is provided with buttock line 8; Described buttock line 8 one ends are connected with the fuse in cartridge fuse 3, and the other end is fixedly connected with contiguous block 6.
As shown in Figure 1, the utility model is before fuse failure, and buttock line 8 pulls contiguous block 6 to be positioned near anti-swing pipe 2 upper port.As shown in Figure 2, after fuse failure, extension spring 5 by contiguous block 6 by buttock line 8 by the interior extraction of cartridge fuse 3, and by the anti-swing pipe 2 of most of buttock line 8 income, only there is the buttock line 8 of few part to stay outside anti-swing pipe 2, guarantee that buttock line 8 can't contact with surrounding devices or conductive component even electricity.
The above is preferred implementation of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also are regarded as protection range of the present utility model.
