Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
In electromagnetism voltage-stabilizing energy-saving device over-voltage over-current protection device embodiment of the present invention, this electromagnetism voltage-stabilizing energy-saving device
With the structural representation of over-voltage over-current protection device as shown in Figure 1.In Fig. 1, this electromagnetism voltage-stabilizing energy-saving device over-voltage and over-current is protected
Protection unit include the first resistance R1, the second resistance R2, the 3rd resistance R3, the 5th resistance R5, the 6th resistance R6, the 8th resistance R8,
First audion Q1, the second audion Q2, the first stabilivolt D1, the second stabilivolt D2, the 3rd diode D3, the 4th diode
D4, the 5th stabilivolt D5, controllable silicon T, LED and anti-thunder tube, wherein, one end of the first resistance R1 exports with rectification
Unidirectional current connect, the other end of the first resistance R1 pass through anti-thunder tube ground connection, the colelctor electrode of the first audion Q1 by the 3rd electricity
Resistance R3 is connected with one end of the first resistance R1 and one end of the second resistance R2 respectively, and the base stage of the first audion Q1 is respectively with second
The emitter stage of the other end of resistance R2, the negative electrode of the first stabilivolt D1, the negative electrode of the second stabilivolt D2 and the second audion Q2 is even
Connecing, the emitter stage of the first audion Q1 connects voltage output end Vout by the 8th resistance R8, and the anode of the first stabilivolt D1 connects
Ground, the anode of the second stabilivolt D2 is connected by the anode of the 5th resistance R5 and the 3rd diode D3, the moon of the 3rd diode D3

First stabilivolt D1 constitutes backup voltage-limiting protection branch road, for when there being thunderbolt to gush pressure, outfan is carried out pressure limiting
Protection.When non-overvoltage, it is output Voltage Cortrol branch road clamper, in open circuit OFF state.If the unidirectional current of rectification output has thunderbolt
Gushing pressure, the both end voltage that output voltage adjusts branch road is too high, and the first stabilivolt D1 opens and base stage carries out pressure limiting again, protection electricity
Pressure output end vo ut.So benefit of design is, backup voltage-limiting protection branch road, when non-overvoltage, is in open-circuit condition, does not produces
Electrical wear, does not damages, and is a kind of Status of Backups, thus when rectification overvoltage, will not the problem that lost efficacy of generating element.First voltage stabilizing
The voltage stabilizing value of pipe D1 adjusts the value of branch road higher than output voltage, namely higher than the output valve after the normal voltage stabilizing of power supply.
Second audion Q2 and LED constitute overcurrent protection display unit, when supporting equipment occurs short
After the fault of road, the electric current through the 8th resistance R8 can increase, voltage when between the emitter stage more than the second audion Q2 and base junction
After, Q2 is open-minded for this second audion, this base bleeder current to the first audion Q1, thus closes the output of the first audion Q1,
The shunting route of base flow is to colelctor electrode from the emitter stage of the second audion Q2, and to ground wire after LED, this
Sample is achieved that overcurrent protection.After the second audion Q2 opens, electric current, through LED, forms light instruction, so
The function of instruction is produced after being achieved that the fault that is short-circuited.When the voltage of the 8th resistance R8 increases, the second audion Q2 is certainly
Dynamic open-minded, automatically recover after Failure elimination, so the over-voltage over-current protection device tool protection automatically of this electromagnetism voltage-stabilizing energy-saving device
With auto restore facility.In the present embodiment, the second audion Q2 is PNP type triode, certainly, in the certain situation of the present embodiment
Under, the second audion Q2 can also be NPN type triode, but at this moment this electromagnetism voltage-stabilizing energy-saving device over-voltage over-current protection device
Circuit structure also to change accordingly.
In the present embodiment, controllable silicon T, the 6th resistance R6 and the 5th stabilivolt D5 constitute Overvoltage protecting unit, controllable silicon T and
5th stabilivolt D5 constitutes triggering branch road, if thunderbolt causes voltage output end Vout too high, and more than the 5th stabilivolt D5's
Turn on after door, thus trigger controllable silicon T conducting, the base stage short circuit to the first audion Q1 immediately, causes the first audion
The output voltage of Q1 is closed, and forms lightning protection overvoltage fast tripping protection.It is to say, the overtension of once voltage output end Vout
Time, controllable silicon T conducting has the strongest positive feedback, can be rapidly by the base stage short circuit of the first audion Q1.And work as voltage output end
After Vout is without overvoltage, can not become trigger to controllable silicon T-shaped, be in open-circuit condition, as long as just working when thunderbolt or overvoltage, institute
To be not easy to damage, the moment, all in a kind of backup protection state, enhances reliability.Second stabilivolt D2 and the 5th resistance R5
Constitute output voltage and adjust branch road.The overvoltage of the present invention and overcurrent protection ability are relatively strong, adapt to civil power wider range, simple in circuits
Easily produce, there is stream instruction function.
