Abstract
The utility model discloses a fuse monitor with a sound-light prompt function. The fuse monitor comprises a direct current power supply, a three-terminal regulator, a piezoelectric buzzer, a triode, a capacitor, a first light-emitting diode, a second light-emitting diode, a diode, a first resistor and a second resistor. According to the fuse monitor with the sound-light prompt function, through detecting connection and disconnection states of the fuse and by means of controlling the piezoelectric buzzer and the light-emitting diodes through the connection and disconnection of the diode and the triode, the alarm function can be realized. The fuse monitor can monitor the working condition of the fuse; when the fuse is fused, the fuse monitor can send out a prompt; the fuse monitor is especially suitable for a fuse that can not be judged whether is broken or not through examination on the appearance; further, the fuse monitor can assist a user or maintenance personnel to quickly and intuitively find the cause of a problem, thereby bringing convenience to maintenance work.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of fuse, relates in particular to a kind of fuse watch-dog with acousto-optic prompting function.
Background technology
As the fuse of circuit safety protection because of cheap, use simple, advantage of wide range of application extensively to be adopted.Having under the situation of a plurality of fuses; Which section blown fuse if the situation of blown fuse just must detect is; Change again; Particularly some is made the fuse of real core or is insured resistance by pottery and so on material, is to judge whether fuse breaks off through the inspection outward appearance, and service work is carried out will be slow.
Summary of the invention
The purpose of the utility model provides a kind of fuse watch-dog with acousto-optic prompting function with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises DC power supply, three terminal regulator, piezoelectric buzzer, triode, electric capacity, first light-emitting diode, second light-emitting diode, diode, first resistance and second resistance; The electrode input end of said three terminal regulator is connected with first end of said second resistance and the positive pole of DC power supply simultaneously; The cathode output end of said three terminal regulator is connected with first end of said piezoelectric buzzer and first end of said first resistance simultaneously; The negative pole of said three terminal regulator is connected with said transistor emitter with the negative pole of said DC power supply simultaneously; Second end of said piezoelectric buzzer is connected with the collector electrode of said triode; The base stage of said triode is connected with first end of said electric capacity and the negative pole of said first light-emitting diode simultaneously; Second end of said first resistance is connected with the positive pole of said diode with the anodal of second end of said electric capacity, said first light-emitting diode simultaneously; Second end of said second resistance is connected with the positive pole of said second light-emitting diode; The negative pole of said second light-emitting diode is connected with the negative pole of said diode, connects fuse between the emitter of said triode and the negative pole of said diode, connects electrical appliance between first end of said second resistance and the negative pole of said second light-emitting diode; Said triode is a NPN type triode.
The beneficial effect of the utility model is:
The utility model is through detecting the on off operating mode of fuse, and controls through the break-make of diode and triode and to force down buzzer and its warning function of light-emitting diode realization.The utility model can be monitored the working condition of fuse; After blown fuse, can send prompting, be particularly useful for judging the fuse of quality through the inspection outward appearance; Find the problem reason with helping user or maintenance personal's quicklook, bring convenience to maintenance work.
Description of drawings
Accompanying drawing 1 is the circuit structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises DC power supply+4 ~ 30V, three terminal regulator IC, piezoelectric buzzer B, triode VT, capacitor C, first LED 1, second LED 2, diode VD, first resistance R 1 and second resistance R 2; The electrode input end of three terminal regulator IC is connected with first end of second resistance R 2 and the positive pole of DC power supply simultaneously; The cathode output end of three terminal regulator IC is connected with first end of piezoelectric buzzer IC and first end of first resistance R 1 simultaneously; The negative pole of three terminal regulator IC is connected with triode VT emitter with the negative pole of DC power supply simultaneously; Second end of piezoelectric buzzer B is connected with the collector electrode of triode VT; The base stage of triode VT is connected with first end of capacitor C and the negative pole of first LED 1 simultaneously; Second end of first resistance R 1 is connected with second end of capacitor C, the positive pole of first LED 1 and the positive pole of diode VD simultaneously; Second end of second resistance R 2 is connected with the positive pole of second LED 2; The negative pole of second LED 2 is connected with the negative pole of diode VD, connects fuse between the negative pole of the emitter of triode VT and diode VD, connects electrical appliance between first end of second resistance R 2 and the negative pole of second LED 2; Triode VT is a NPN type triode.
Shown in accompanying drawing: circuit is suitable for operating voltage can be from 4V to 30V, and three terminal regulator IC provides stable 5V voltage to supply observation circuit to use.Even supply voltage drops to 4V, circuit still can be monitored the working condition of fuse FU reliably.When fuse FU just often, diode VD forward conduction, not enough first LED 1 of its forward voltage drop and triode VT work, at this moment triode VT ends, piezoelectric buzzer B is sounding not, circuit is in the monitoring holding state.In case fuse FU breaks off, the load power source loop is cut off, and diode VD ends at this moment; The 5V supply voltage is through first resistance R 1; First LED 1 makes triode VT conducting immediately, and piezoelectric buzzer B gets the electric alarm sound prompting of sending, and first LED 1 is because have electric current to flow through also ceaselessly to glimmer luminous simultaneously; Thereby the acousto-optic of realizing circuit is reminded, and reports to the police.The effect of capacitor C is to prevent owing to break-make in first LED, 1 course of work causes piezoelectric buzzer B " snapping " sound is arranged.Second LED 2 is load power source indicator lights.Fuse FU just often, second LED, 2 luminous indicate fuse FU and load power source are in proper working order.
