Abstract
The utility model relates to a lightning protection device capable of continuously absorbing surge, comprising a piezoresistor, a gas discharge tube, a current-limiting resistor, and a transient inhibition diode, wherein the piezoresistor and the gas discharge tube are arranged in serial connection, with one end of the gas discharge tube being grounded; the current-limiting resistor and the transient inhibition diode are arranged upon the piezoresistor in parallel connection; and the current-limiting resistor and the transient inhibition diode are arranged in serial connection. The lightning protection device of the utility model combines the advantages of the piezoresistor and the gas discharge tube together by simultaneously comprising both the piezoresistor and the gas discharge tube, thereby allowing the lightning protection device to effectively and continuously discharge and restrict lightning current and thunder voltage.
Description
[technical field]
The utility model relates to a kind of continuous absorption surge lightning protection device, belongs to the thunder resisting equipment technical field.
[background technology]
Natural lightning current is that continual several transient state electrical waveform stack forms.The lightning protection device of a common 40KA; Possibly will explode at the lightning wave that occurring in nature receives a 5KA and burn, its main cause be lightning protection device inner the votage limit type components and parts--piezo-resistance can not be born continuous lightning impulse (all be continuous time in several microseconds).
If lightning protection device adopts gas discharge tube as pressure limiting unit's device then there is not above-mentioned problem, but because more than 100 nanoseconds of response time of gas discharge tube, therefore, the effect of deboost is not as piezo-resistance.
For solving the problems of the technologies described above, necessary a kind of structure improved continuous absorption surge lightning protection device that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is to provide a kind of continuous absorption surge lightning protection device of can effectively release continuously restriction lightning current, lightning voltage.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of continuous absorption surge lightning protection device, and it comprises piezo-resistance, gas discharge tube, current-limiting resistance and Transient Suppression Diode; Wherein, said piezo-resistance and gas discharge tube series connection are provided with, and an end ground connection of gas discharge tube; On said piezo-resistance, be parallel with said current-limiting resistance and Transient Suppression Diode; Said current-limiting resistance and Transient Suppression Diode are series connection setting.
The continuous absorption surge lightning protection device of the utility model further is set to: said Transient Suppression Diode is specially 4, and it is parallel connection setting.
Compared with prior art; The utlity model has following beneficial effect: the continuous absorption surge lightning protection device of the utility model is through be provided with piezo-resistance and gas discharge tube simultaneously; And have the advantage of two kinds of elements concurrently, thereby make this lightning protection device can effectively release continuously restriction lightning current, lightning voltage.
[description of drawings]
Fig. 1 is the schematic diagram of the continuous absorption surge lightning protection device of the utility model.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of continuous absorption surge lightning protection device, and it is electrically connected by several elements such as piezo-resistance 1, gas discharge tube 2, current-limiting resistance 3 and Transient Suppression Diode 4 and forms.
Wherein, 2 series connection are provided with said piezo-resistance 1 with gas discharge tube, and an end ground connection of gas discharge tube 2.Said gas discharge tube 2 works release thunder and lightning transient state overcurrent and over-voltage effect.
On said piezo-resistance 1, be parallel with said current-limiting resistance 3 and Transient Suppression Diode 4.Said current-limiting resistance 3 is series connection setting with Transient Suppression Diode 4.Said Transient Suppression Diode 4 is specially 4, and it is parallel connection and is provided with, and this Transient Suppression Diode 4 surge that produces of can avoiding being struck by lightning causes damage to element.
The continuous absorption surge lightning protection device operation principle of the utility model is following: branch road of parallel connection on piezo-resistance 1, this route current-limiting resistance 3 is formed with Transient Suppression Diode 4.In the process that lightning current takes place, the little current start of elder generation, promptly branch road starts, and excited gas discharge tube 2 starts; After lightning current progressively becomes greatly, by piezo-resistance 1 discharge; Start discharge by branch road again if lightning current descends, make piezo-resistance 1 pressure that is eased, so under the surge that continues, this lightning protection device can effectively release continuously restriction lightning current, lightning voltage.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
Claims (2)
1. one kind absorbs the surge lightning protection device continuously, it is characterized in that: comprise piezo-resistance, gas discharge tube, current-limiting resistance and Transient Suppression Diode; Wherein, said piezo-resistance and gas discharge tube series connection are provided with, and an end ground connection of gas discharge tube; On said piezo-resistance, be parallel with said current-limiting resistance and Transient Suppression Diode; Said current-limiting resistance and Transient Suppression Diode are series connection setting.
