Description
Technical field
The utility model is related to a kind of lightning protection device, specifically network two-in-one lightning.
Background technology
With developing rapidly for internet science and technology, internet turns into the indispensable instrument of people's live and work.But
When being that the thunder and lightning of nature occurs, the current surge of sensing can be caused in power supply and communication line, equipment is damaged.Its reason exists
It is such as super large-scale integration (VLSI) chip because electronic equipment internal structure height is integrated in one side, so that
Cause that equipment is pressure-resistant, level of resistance to overcurrent declines, the ability to bear decline to thunder and lightning such as induced lightening or switching overvoltage surge；
On the other hand it is due to that signal source path increases, system was than being easier to be invaded by lightning wave in the past, and surge voltage
In computer equipment being scurried into from the approach such as power line or signal wire.
For this problem, in the market has released the external lightning protection device of many moneys, but in the external lightning protection device of outdoor mounted, there is very big
Hidden danger, lightning protection effect is poor；When lightning rod in thunderbolt, very strong transient electric field can be produced being connected to around the lead of the earth,
The equipment and transmission line being in electromagnetic field can induce larger electromotive force, and the energy of transient electric field reaches that 1.5KA can be hit
Wear standby dielectric and invade device interior, so that inner member is broken；The circuit that external lightning protection device is applied all is
Traditional safe secondary protection circuit, the defect of its circuit is that residual voltage is high, and after thunderbolt, after the fuse resistance excessively stream in circuit
It can be damaged, can just be reused after need to changing, artificial and Material Cost will not only be spent by changing device, due to not timely
Replacing device also results in equipment and is damaged.
Utility model content
The utility model purpose be intended to provide a kind of circuit structure it is simple, can be to the power circuit and network of equipment
The network two-in-one lightning that signal circuit is protected comprehensively.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：

Double insurance silk F5, the piezo-resistance RV5 of resettable fuse F6 series connection, Transient Suppression Diode TVS2, piezo-resistance
RV6。
Using the utility model of above-mentioned technical proposal, resettable fuse F1, resettable fuse F2, resettable fuse
F3, resettable fuse F4, resettable fuse F5, resettable fuse F6, are less than its holding electric current when flowing through its electric current
When, its resistance very little, when flowing through its electric current more than its trigger current, its resistance increased dramatically rather than fuse, from
And the continuation intrusion or the afterflow of circuit of overcurrent are blocked, voluntarily recover after temperature reduction, play a part of sustainable protection, together
When avoid thunderbolt after because device failure does not change the loss brought in time, it is cost-effective.
Connected light emitting diode D and piezo-resistance RV1, the pottery for ground connection of connecting again parallel with one another by resettable fuse F1
The power supply one-level lightning protection of porcelain gas-discharge tube G1 compositions, when lightning surge overvoltage overcurrent is with power input circuit,
The electric current for flowing through resettable fuse F1 exceedes its trigger current, and its resistance increased dramatically, so as to block the continuation of lightning current
Intrusion or the afterflow of circuit, and then protect the safety of rear circuit；Piezo-resistance RV1 is because of its unique pressure-limiting function, when adding
Its resistance can diminish when the overvoltage for being loaded in two-stage exceedes its threshold value, so allow for flowing through its electric current increase sharply and to other electricity
The influence on road is less so as to play a part of suppressing clamper overvoltage；The light emitting diode DLED in parallel with piezo-resistance RV1 can
Luminescence display is carried out in power input；The ceramic discharge tube G1 ground connection of series connection can be by the powerful common mode energy of overvoltage overcurrent
Bleed off is to greatly.Between two grades of lightning protections of power supply one-level lightning protection and power supply series inductance L1, resistance R1, inductance L2,
Resistance R2 to the remaining overvoltage overcurrent progress decoupling after prime lightning protection and can be gripped as decoupling choke circuit
Stream, reduces their impacts to rear circuit；Resettable fuse F2 connects piezo-resistance RV2 as two grades of lightning protection guarantors of power supply
Shield, using the current limliting and the pressure limiting characteristic of piezo-resistance of resettable fuse, can clamp down on remaining excessively electric after prime is protected
Pressure and overcurrent, suppress the impact of surge differential mode energy；Resettable fuse F3, piezo-resistance RV3, the pressure-sensitive electricity being sequentially connected in series
RV4, resettable fuse F4 are hindered, then the ceramic gas of a ground connection in parallel is put between piezo-resistance RV3 and piezo-resistance RV4
Fulgurite G2, by preceding two-stage lightning protection, appoints the common mode energy for so having remnants to exist as power supply three-level lightning protection, pressure-sensitive
Remaining Lightning Over-voltage can be clamped to safe range by resistance RV3, piezo-resistance RV4, and resettable fuse F3, self- recoverage are protected
Dangerous silk F4 can play a part of current limliting, and remaining common mode energy can be imported the earth by ceramic gas discharge tube G2.
Protected by the ceramic gas discharge tube G3, the ceramic gas discharge tube G4 that are in series the network signal one-level lightning protection constituted
Shield, when lightning surge overvoltage overcurrent is with network signal incoming line, ceramic gas discharge tube G3, ceramic gas discharge tube
G4 can signal input part side directly by overvoltage surge and overcurrent bleed off to greatly, to reduce the impact to rear circuit.
Two grades of the network signal being made up of the resettable fuse F5, Transient Suppression Diode TVS1, resettable fuse F6 that connect is prevented
Thunder protection is mainly used in reducing residual voltage, and the instantaneous power of right ceramic gas discharge tube is big, but residual voltage is very high, self- recoverage insurance
Silk F5, resettable fuse F6, can be to follow-up using its electric current characteristic that resistance increased dramatically more than its trigger current is flowed through
Circuit realiration is protected, and Transient Suppression Diode TVS1, can be with 1ps speed by the resistance of its two interpolar by reverse surge impact greatly
Resist by high step-down, the surge power that up to thousands of watts of absorption makes the current potential clamper of two interpolars in predetermined value, effectively protects rear end
The infringement of component in equipment from surge pulse.By being gone here and there with the resettable fuse F5, the resettable fuse F6
The network signal three-level lightning protection that piezo-resistance RV5, Transient Suppression Diode TVS2, the piezo-resistance RV6 of connection are constituted is main
For clamping the voltage at safe range.
