The fusion tube has the following beneficial effects: by adopting the fusing warning indicator and other structures, the state of the fuse element is easy to intuitively observe through the fusing warning indicator when the circuit or the equipment in the circuit is overloaded or has fault, without dismantling the fusion tube, thus greatly improving the efficiency and reliability of judging whether the line has fault by the staff.
Description
Technical field
The invention belongs to the electric power system detection range, relate in particular to a kind of fuse tube that is used for the high-tension line fault detect.
Background technology
At present, traditional fuse tube generally all is high insulation high strength shell two ends button metal caps, connects fuse in the middle of two metal caps, and perfusion quartz sand is formed in the shell then.Fuse is the wire that utilizes the lower metal material of fusing point to make, and is connected in the protected circuit.When the apparatus overload in circuit or the circuit or when breaking down, fuse heating and melting, thus cut off circuit, reach the purpose of protective circuit or equipment.Yet traditional fuse tube is not easy intuitively to observe fuse state when fuse failure, need will could detect after the fuse tube dismounting, and operating wastes time and energy, and has increased the cost of overhaul.
Summary of the invention
The present invention provides a kind of fuse tube that is used for the high-tension line fault detect for solving the technical problem that exists in the known technology, be intended to solve fuse tube traditional when fuse failure and be not easy intuitively to observe fuse state, need be with the problem that could detect after the fuse tube dismounting.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of fuse tube that is used for the high-tension line fault detect is characterized in that, described fuse tube comprises fuse tube housing, metal cap, fuse, spring holder, signal body, energy-stored spring, fusing attention device and metal cap base;
Described fuse tube housing upper end is buckled with metal cap, and the lower end is buckled with described metal cap base; The upper end of described fuse is fixed on the described metal cap; The lower end of described fuse is fixed by described spring holder and signal body; Between described signal body and the metal cap base energy-stored spring is installed; Also be fixed with described fusing attention device on the described signal body.
The present invention can also be further by the following technical solutions:
Described fuse passes through the fuse snap fit on metal cap.
The outside of described metal cap base also is equipped with transparent display tube.
Described fusing attention device is the danger signal board.
Described fuse tube housing is made up of porcelain jar body and metallic object.
The present invention is by adopting structures such as energy-stored spring, signal body, fusing attention device, when the apparatus overload in circuit or the circuit or when breaking down, and fuse heating and melting, thus cut off circuit; When fuse failure,, do not need to improve efficient and reliability that the staff judges whether circuit breaks down greatly with detecting after the fuse tube dismounting by fusing attention device observation fuse state directly perceived easily.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify the following example of executing now, and conjunction with figs. is described in detail as follows:
Fig. 1 shows the structural representation of the fuse tube that is used for the high-tension line fault detect that the embodiment of the invention provides, and for convenience of explanation, only shows part related to the present invention.
A kind of fuse tube that is used for the high-tension line fault detect, this fuse tube comprise fuse tube housing 7, metal cap 2, fuse 6, spring holder 3, signal body 8, energy-stored spring 9, fusing attention device 10 and metal cap base 5;
Described fuse tube housing 7 upper ends are buckled with metal cap 2, and the lower end is buckled with described metal cap base 5; Described fuse 6 is installed in the inside of described fuse tube, and the upper end of described fuse 6 is fixed on the described metal cap 2; The lower end of described fuse 6 is fixing by described spring holder 3 and described signal body 8; Between described signal body 8 and the metal cap base 5 energy-stored spring 9 is installed; Also be fixed with described fusing attention device 10 on the described signal body 8.
As a preferred version of the embodiment of the invention, described fuse is fixed on the metal cap 2 by fuse buckle 1.
As a preferred version of the embodiment of the invention, the outside of described metal cap base 5 also is equipped with transparent display tube 11.
As a preferred version of the embodiment of the invention, described fusing attention device 10 is the danger signal board.
As a preferred version of the embodiment of the invention, described fuse tube housing 7 is that porcelain jar body and metallic object are formed.
The mounting means compatibility of the mounting means of the fuse tube that the embodiment of the invention provides and traditional fuse tube is installed in novel fuse tube on the position identical with traditional fuse.
Fig. 2 is schematic diagram before the fuse tube fusing, and Fig. 3 is the schematic diagram of fuse tube after fusing.When the apparatus overload in circuit or the circuit or when breaking down, the fuse 6 in the fuse tube fuses, and makes energy-stored spring 9 discharge downward power, and the feasible fixedly signal body 8 of fuse 6 bottoms moves down.
After the signal body 8 that the pulling of the elastic force of energy-stored spring 9 is fixed with fuse 6 moves down.Because the signal body connects fusing attention device 10, after energy-stored spring 9 releases energy, make fusing attention device 10 move down, and then in transparent display tube 11, show.As long as in transparent display tube 11, see fusing attention device 10, can judge intuitively that the fuse in the fuse tube fuses, the reply high-tension line overhauls and changes fuse tube of the present invention.
When circuit generation fault, the fuse 6 in the novel fuse tube fuses, and makes energy-stored spring 9 discharge downward power, after spurring the signal body 8 that is fixed with fuse 6 and moving down.Because the signal body connects fusing attention device 10, after energy-stored spring 9 releases energy, make fusing attention device 10 move down, and then in transparent display tube 11, show, can make the people judge that intuitively the fuse in the fuse tube fuses, the reply high-tension line overhauls and changes fuse tube of the present invention.
Fuse tube provided by the invention is mainly used in the electric power system detection range, the staff is as long as see fusing attention device 10 in transparent display tube 11, do not need cartridge fuse dismounting back is detected, can judge intuitively that the fuse 6 in the fuse tube has fused, the reply high-tension line overhauls and changes fuse tube of the present invention.Novel fuse tube can improve efficient and the reliability that the staff judges whether circuit breaks down greatly.
The above only is to preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention is to any simple modification that above embodiment did, and equivalent variations and modification all belong in the scope of technical solution of the present invention.
