Abstract
The utility model relates to a fuse with an open-circuit display device, which belongs to an electric appliance element. The fuse comprises a shell, two electrodes which are installed on two ends of the shell and a melt which is connected between the two electrodes. A large-resistance visible-light display device is arranged between the two electrodes in parallel, and the shell is transparent. The large-resistance visible-light display device can be a neon lamp. The large-resistance visible-light display device also can comprise a dropping resistor and a neon lamp which is connected with the dropping resistor in series. Once the melt of the fuse is burned out, the burn-out of the melt can be clearly displayed through the visible light. Therefore, the maintenance personnel can instantaneously confirm which fuse is burned out and is required to replace, so the time is saved, the maintenance efficiency is improved, and the fuse is very convenient to repair. The fuse with the open-circuit display device can be widely applied in different high-voltage circuits and different low-voltage circuits.
Description
Technical field
The utility model belongs to the electric elements technical field, more particularly relates to the design and the improvement of the fuse that has the display that opens circuit.
Background technology
Fuse is also referred to as fuse or fuse-link.It is a kind of being installed in the circuit, guarantees the electric elements of circuit safety operation.When circuit breaks down or be unusual, thereby electric current can continuous rising cause overcurrent.Too high electric current may damage some important devices in the circuit, even burns circuit and cause fire.The effect of fuse is exactly that melt is fused failure of current, and then the safe operation of protective circuit when overcurrent takes place.
Traditional fuse there is no any demonstration when melt is cut off.Thereby often need to examine or could confirm with meter check whether melt has fused and whether need to be changed.If many fuses are installed in the circuit, determine which root is fused and is not easy, need by the root inspection.This brings difficulty or puzzlement just for the line maintenance personnel, has wasted the time, has reduced maintenance efficiency, and is very inconvenient.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of fuse that has the display that opens circuit is provided.When in a single day the melt of this fuse is fused, can know with visible light simultaneously to show.This just makes the maintenance personal will confirm which root fuse need be changed by fusing moment, has saved the time, has improved maintenance efficiency, and is very convenient.
In order to achieve the above object, the utility model comprises housing, is installed in two electrodes at housing two ends and is connected two melts between the electrode, big resistance visible light display in parallel between two electrodes, and housing is transparent.
Big resistance visible light display can be neon tube.
Big resistance visible light display can comprise dropping resistor and the neon tube of connecting with dropping resistor.Dropping resistor can reduce part voltage, and the protection neon tube is avoided being burnt out better effects if.
When the circuit operate as normal, because of the resistance of very little big resistance visible light display of the resistance of melt or neon tube is bigger, electric current will be by the melt conducting, greatly in resistance visible light display or the neon tube because of no current passes through, can luminously not show.When circuit broke down or be unusual, the electric current by melt increased the generation overcurrent rapidly, and melt is fused.Voltage between two electrodes all is added on big resistance visible light display or the neon tube, just makes its luminous demonstration.Whether transparent housing is convenient to observe melt and is fused.
Task of the present utility model comes to this and finishes.
When in a single day the melt of the utility model fuse is fused, can know with visible light simultaneously to show.This just makes the maintenance personal will confirm which root fuse need be changed by fusing moment, has saved the time, has improved maintenance efficiency, and is very convenient.It can be widely used in the various hi-lo circuits.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment 1.A kind of fuse that has the display that opens circuit, as shown in Figure 1.It comprises housing 1, be installed in two electrodes 2 at housing 1 two ends and be connected big resistance visible light display in parallel between 3, two electrodes 2 of two melts between the electrode 2, and housing 1 is transparent.Big resistance visible light display comprises dropping resistor 4 and the neon tube 5 of connecting with dropping resistor 4.
When the circuit operate as normal, because of the resistance of the very little neon tube 5 of resistance of melt 3 is bigger, electric current will because of no current passes through, can luminously not show in the neon tube 5 by melt 3 conductings.When circuit broke down or be unusual, the electric current by melt 3 increased the generation overcurrent rapidly, and melt 3 is fused.Voltage between two electrodes 2 all is added on the neon tube 5, makes its luminous demonstration.Whether transparent housing 1 is convenient to observe melt 3 and is fused.
When in a single day the melt of embodiment 1 fuse is fused, can know with visible light simultaneously to show.This just makes the maintenance personal will confirm which root fuse need be changed by fusing moment, has saved the time, has improved maintenance efficiency, and is very convenient.It can be widely used in the various hi-lo circuits.
Claims (3)
1. a fuse that has the display that opens circuit comprises housing, is installed in two electrodes at housing two ends and is connected two melts between the electrode, it is characterized in that between two electrodes big resistance visible light display in parallel, and housing is transparent.
