Fuse electric loading Intelligent indicating device

Technical field

The utility model belongs to electrotechnics and electronics field, is about a kind of fuse electric loading Intelligent indicating device.

Background technology

The icy face of fuse in 220V alternating current power distribution, its duty is very directly perceived, as: when electricity consumption generation blowout at night or when running into the situations such as power failure, electricity consumer for the moment cannot failure judgement character fast.

The circuit of fuse electric loading Intelligent indicating device described in the utility model only uses a light emitting diode, by the change of flashing rate can indicate single-phase alternating current presence or absence, the work of electricity consumption load can also be indicated whether, it is applicable to noiseless, unglazed etc. to indicate with the energising of electric loading.

Below describe in detail fuse electric loading Intelligent indicating device described in the utility model necessity involved in implementation process, guardian technique content.

Utility model content

Goal of the invention and beneficial effect: the circuit of fuse electric loading Intelligent indicating device described in the utility model only uses a light emitting diode, by the change of flashing rate can indicate single-phase alternating current presence or absence, the work of electricity consumption load can also be indicated whether, it is applicable to noiseless, unglazed etc. to indicate with the energising of electric loading.Electricity consumer also can be known at night and see that the duty of fuse to connect or whether boiled, fuse output terminal has the situations such as electricity, for electric consumer judges that 220V AC power and the duty by electric loading provide reference exactly, electric consumer is avoided to cause man-made fault because blindly operating.

Circuit working principle: when fuse BX in circuit disconnects, the positive half cycle of 220V alternating current charges to electrochemical capacitor C1 through resistance R1 and silicon rectifier diode Dl.When the voltage on electrochemical capacitor C1 is charged to about 30V, bidirectional trigger diode KS punctures in pole low impedance state, and electrochemical capacitor C1 is by bidirectional trigger diode KS, LED electric discharge, and LED is lighted.Along with electrochemical capacitor C1 is discharged gradually, bidirectional trigger diode KS ends, and LED extinguishes, and circuit will enter next charge and discharge cycle, LED just constantly flashing.The resistance of resistance R1 determines the duration of charging of electrochemical capacitor C1, also determines the glittering frequency of LED, and this situation shows that 220V AC-powered is normal.

At night, when fuse BX blows, the glimmer low-light that sends of LED can be used as the temporary lighting of panel box, and electricity consumer can check processing circuitry fault by low-light, and power consumption during indicating device work is very micro-, substantially can ignore.Electricity consumer is according to LED flicker frequency or do not work, and accurately can judge the nature of trouble of 220V alternating current transmission line.

When connecting fuse BX and working with electric loading RL, 220V alternating current charges to electrochemical capacitor C1 through resistance R1, silicon rectifier diode Dl and resistance R2, the parallel connection of silicon rectifier diode D2 two-way simultaneously, electrochemical capacitor C1 charging rate is obviously accelerated, the flicker frequency showing as LED accelerates, illustrate that fuse BX is intact, also explanation electric loading RL has been energized work.

From circuit working principle, when fuse BX blows, due to the unilateal conduction effect of silicon rectifier diode D1, silicon rectifier diode D2, be no matter positive half cycle or the negative half period of 220V alternating current, with on electric loading RL all no current pass through.The utility model is different from the indicator light circuit being usually connected in parallel on fuse BX two ends, when fuse BX blows, has faint electric current by making pilot lamp luminous with electric loading RL.
