Semiconductor device is very sensitive to electrostatic, overvoltage, overcurrent, it is easy to damage, and lightning protection relevant criterion is advised
These microelectronic device system fixed all should set up independent grounding system, and earth resistance requires 1 ohm.
At present earthed system uses the mode of joint grounding substantially, the place of working of all electronic electric equipments,
Protecting field and various lightning protection collect in a grounded screen, when earth mat produces high pressure, big electric current,
According to EMC characteristic, weak electricity system probably suffers the harm that high pressure counterattack, lightning current are invaded, and causes weak
The microelectronic component of ground system is because of high pressure, overcurrent damage and interference.In ideal conditions, weak ground system
Ground connection should independently be separated with strong power system ground connection, isolate, and could really stop strong power system impact weak ground system
Normal work.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide one to have earthed system
The grounding-for-lightning device of high pressure counterattack " dividing potential drop isolation, constrain decay " function.
For achieving the above object, this utility model can be achieved by the following technical programs:
Grounding-for-lightning device, including weak ground earthed system and strong ground earthed system, also includes earth potential potentiometer
Connect respectively with two outfans of earth potential unloader, described earth potential potentiometer and earth potential unloader
Weak ground earthed system and strong ground earthed system, described earth potential potentiometer includes the first perception unit being connected in parallel
Part and non-linear votage limit type device, described earth potential unloader is by the second inductive element, nonlinear switching type device
Part and safety electric capacity composition, after described nonlinear switching type device and safety capacitances in series again with inductive element also
Connection.
Further, described first inductive element and the second inductive element are inductance.
Further, described non-linear votage limit type device is varistor.
Further, described nonlinear switching type device is Surge Protector.
This utility model simple in construction, convenient and practical, effectively the counterattack suppression of earth potential high pressure is blocked, with
Time again weak be grouped by force isolation, reach dividing potential drop isolation, the effect of constrain decay, solve to combine and connect
Earth mat causes the problem that weak ground system equipment damages.Use this technology to union ground grid resistance sizes without any
Impact, thus big ground resistance earthed system ground connection can be realized.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is further described:
As it is shown in figure 1, grounding-for-lightning device described in the utility model, mainly include weak ground earthed system A,
Strong ground earthed system B, earth potential potentiometer C and earth potential unloader D.Wherein, earth potential potentiometer C
Two outfans connect weak ground earthed system A and strong ground earthed system B, two of earth potential unloader D respectively
Outfan connects weak ground earthed system A and strong ground earthed system B respectively.Weak ground earthed system A and connecing by force
The connection end of ground system B can be copper bar or terminal block.
As in figure 2 it is shown, earth potential potentiometer C is by the first inductive element 3 and non-linear votage limit type device 4 groups
Become.Concrete, the first inductive element 3 and non-linear votage limit type device 4 are connected in parallel, and the two ends of circuit are divided
Wei the outfan 1 of earth potential potentiometer and the outfan 2 of earth potential potentiometer.
As it is shown on figure 3, earth potential unloader D is by the second inductive element 13, nonlinear switching type device 14 and
Safety electric capacity 15 forms.Concrete, after nonlinear switching type device 14 and safety electric capacity 15 series connection again with sense
Property element 13 in parallel, the two ends of circuit are respectively outfan 11 and the earth potential unloader of earth potential unloader
Outfan 12.
Preferably, the first inductive element 3 and the second inductive element 13 all use inductance, non-linear votage limit type device
4 use varistor, and nonlinear switching type device 14 uses Surge Protector.
This utility model be weak and by force between be incorporated to an earth potential potentiometer C and an earth potential presses down
Depressor D, weak, by force independent separately, isolation, be independent of each other respective normal work mutually.There is no thunder
When electricity or big electric current enter strong ground system, weakly and by force between be in zero resistance state.When strong ground system
When having lightning current to invade, cause the instantaneous rising of earth potential, at this moment earth potential potentiometer C, earth potential unloader D
Simultaneously with the speed responsive of nanosecond, the isolation of effective dividing potential drop, constrain decay, force weakly systematically at current potential
In zero change.
For a person skilled in the art, can be made other each according to above technical scheme and design
Kind corresponding change and deformation, and all these changes and deformation all should belong to this utility model right
Within the protection domain required.
