Description
Technical field
The invention belongs to electrotechnics and electronics field, is on a kind of fuse electric loading Intelligent indicating device.
Background technology
The icy face of fuse in 220V alternating current power distributions, its working condition is not very directly perceived, such as：When night electricity consumption is sent out
Raw blowout or when running into power failure, electricity consumer for the moment can not quick failure judgement properties.
Fuse of the present invention, only with a light emitting diode, passes through sudden strain of a muscle with the circuit of electric loading Intelligent indicating device
The change of light frequency can indicate that the presence or absence of single-phase alternating current, also can indicate that with the work of electric loading whether, it is applied to
The energization with electric loading such as noiseless, unglazed indicates.
The defects of in order to make up and overcome existing fuse to be indicated without working condition, it is necessary to which developing one kind can indicate to protect
Dangerous silk BX working condition servicing units, make electricity consumer can be also clearly seen at night fuse working condition be to turn on or
Whether boiled, fuse output end has situations such as electricity, judges 220V AC powers and the work with electric loading exactly for electric consumer
Make state provide reference, avoid electric consumer because blindness operation and caused by man-made fault.
Fuse of the present invention described further below with electric loading Intelligent indicating device in implementation process it is involved
Necessary, key technique content.
The content of the invention
Goal of the invention and beneficial effect：Fuse of the present invention is with the circuit of electric loading Intelligent indicating device only with one
Light emitting diode, the presence or absence of single-phase alternating current can indicate that by the change of flash frequency, also can indicate that and use electric loading
Work whether, it is applied to the energization with electric loading such as noiseless, unglazed and indicated.Electricity consumer is set also to be clearly seen at night
The working condition of fuse is to turn on or whether boiled, fuse output end has situations such as electricity, is judged exactly for electric consumer
220V AC powers and provide reference with the working condition of electric loading, avoid electric consumer because blindness operation and caused by man-made fault.
Circuit operation principle：When fuse BX disconnects in circuit, the positive half cycle of 220V alternating currents is whole through resistance R1 and silicon
Diode Dl is flowed to charge to electrochemical capacitor C1.When the voltage on electrochemical capacitor C1 is charged to about 30V, bidirectional trigger diode KS
Breakdown is in extremely low impedance state, and electrochemical capacitor C1 is discharged by bidirectional trigger diode KS, LED, light-emitting diodes
Pipe LED is lighted.As electrochemical capacitor C1 is gradually discharged, bidirectional trigger diode KS cut-offs, LED extinguishes, electricity
Road will enter next charge and discharge cycle, LED just constantly flashing.Resistance R1 resistance determines electricity
Electric capacity C1 charging interval is solved, also determines the glittering frequency of LED, this situation is showing 220V AC-powereds just
Often.
At night, when fuse BX blows, the low-light that LED flicker is sent can be as the interim of distribution box
Illumination, electricity consumer can check process circuit failure by low-light, and power consumption when instruction device works is little, can neglect substantially
Slightly.Electricity consumer is according to LED flicker frequency or does not work, can be with the fault of accurate judgement 220V alternating current transmission lines
Matter.
When connection fuse BX is worked with electric loading RL, 220V alternating currents are through resistance R1, silicon rectifier diode Dl and electricity
Hinder R2, the parallel connection of silicon rectifier diode D2 two-ways while charged to electrochemical capacitor C1, electrochemical capacitor C1 charging rates are substantially accelerated, table
Now accelerated for the flicker frequency of LED, illustrate that fuse BX is intact, also explanation has been powered work with electric loading RL.
From circuit operation principle, when fuse BX blows, due to silicon rectifier diode D1, silicon rectifier diode D2
Unilateal conduction effect, the either positive half cycle or negative half period of 220V alternating currents pass through with all no currents on electric loading RL.This
Invention is different from the indicator light circuit for being generally connected in parallel on fuse BX both ends, when fuse BX blows, has faint electric current to lead to
Cross makes indicator lamp light with electric loading RL.
Technical scheme：Fuse electric loading Intelligent indicating device, it includes 220V AC powers, halfwave rectifier and filtering
