Abstract
The invention provides a lightning arresting method and device with function of inhibiting lightning stroke current intensity and relates to a lightning arresting method and device with function of inhibiting lightning stroke current intensity which are applied to direct lightning flash protection of buildings. The device comprises a lightning arrester, at least one high-frequency impulse transformer and a grounded device, wherein the high-frequency impulse transformer comprises a primary coil, a magnetic core and a secondary short circuit coil; the primary coil and the secondary short circuit coil form electromagnetic coupling through the magnetic core; a loop is formed by the secondary short circuit coil; and when more than two high-frequency impulse transformers are arranged, the primary coils of the high-frequency impulse transformers are connected in series with a loop formed by the lightning arrester and the grounded device. When lightning stroke current passes through the lightning arrester, the primary coils of the high-frequency impulse transformers and a lightning stroke release loop, energy in the primary coils is coupled to the secondary short circuit coils through the magnetic cores of the high-frequency impulse transformers and is consumed by internal resistors of the secondary short circuit coils, and thus the size of the lightning stroke current in the lightning stroke release loop is limited and the purpose of inhibiting the lightning stroke current is achieved.

Background technology
The device that does not all have effectively to suppress thunder-strike current intensity in arrester (being commonly called as lightning rod) that lightning protection such as present building are used and the thunderbolt energy bleed-off circuit, the direct lightning strike electric current enters the earth by arrester and bleed-off circuit, its current strength is decided by the quantity of electric charge of charged cloud layer, the height of voltage, the impedance of bleed-off circuit and earth resistance, because the impedance and the earth resistance of thunder-strike current bleed-off circuit are little, the direct lightning strike size of current does not wait in tens kilo-amperes to hundreds of kilo-amperes, produce powerful Lightning Electromagnetic Pulse, diverse location at the thunder-strike current bleed-off circuit produces very high space potential simultaneously, because the existence of electrostatic induction and electromagnetic induction, power-supply system in peripheral certain limit, produce overvoltage surge (being indirect lightning strike) in the signal system, damage power-supply system, signal system and this power supply, electronic equipment in the signal system.
If in thunder-strike current is released process, effectively consume the energy of thunderbolt, just can control the size of thunder-strike current in the thunder-strike current bleed-off circuit effectively, thereby alleviate LEMP and electrostatic induction intensity, and then alleviate the degree of protection of overvoltage surge overvoltage surge in peripheral electronic equipment power source system, the signal system.
Summary of the invention
The present invention is intended to overcome the drawback that not have effectively to suppress the device of thunder-strike current intensity in arrester that lightning protection such as existing structure uses and the thunderbolt energy bleed-off circuit, releases a kind ofly to connect sudden strain of a muscle method and device thereof with the inhibition of thunder-strike current intensity.To be a kind of direct lightning strike connect sudden strain of a muscle method and device thereof to the protection at building, wind power generation, solar power generation, naval vessel, communication equipment station or the like for it, particularly can effectively consume the thunderbolt energy, suppress in the thunder-strike current bleed-off circuit, be that a kind of direct lightning strike that suppresses the thunder-strike current size connects the sudden strain of a muscle device therefore.
To achieve these goals, finish above-mentioned task, sudden strain of a muscle method that connects that band thunder-strike current intensity of the present invention suppresses and device thereof adopt following technical scheme:
The sudden strain of a muscle method that connects that band thunder-strike current intensity of the present invention suppresses, between arrester and earthing device, the connect primary coil of at least one high-frequency pulse transformer, described high-frequency pulse transformer comprises described primary coil, magnetic core and secondary short circuited coil, make described primary coil and secondary short circuited coil form electromagnetic coupled by magnetic core, the secondary short circuited coil has the loop of one's own.
The arrester device that band thunder-strike current intensity of the present invention suppresses, comprise arrester, at least one high-frequency pulse transformer and earthing device, described high-frequency pulse transformer comprises primary coil, magnetic core and secondary short circuited coil, make primary coil and secondary short circuited coil form electromagnetic coupled by magnetic core, the secondary short circuited coil has the loop of one's own; When being a high-frequency pulse transformer, the two ends of the primary coil of described high-frequency pulse transformer are connected with earthing device with arrester respectively; When being plural high-frequency pulse transformer, the primary coil of described high-frequency pulse transformer is series in the loop of arrester and earthing device formation.
Arrester is the point discharge arrester.
Described magnetic core is a high frequency magnetic core.
Mechanism of the present invention is: thunder-strike current by arrester, high-frequency pulse transformer primary coil and during bleed-off circuit, energy in the primary coil is coupled to the secondary short circuited coil by the magnetic core of high-frequency pulse transformer, and by the internal resistance consumption of secondary short circuited coil, thereby the size of the thunderbolt pulse current of restriction thunderbolt bleed-off circuit reaches and suppresses the thunder-strike current purpose.
The present invention compares with prior art, its beneficial effect is: one, can limit the size of the thunderbolt pulse current of thunderbolt bleed-off circuit, thereby alleviate LEMP and electrostatic induction intensity to overvoltage surge in peripheral electronic equipment power source system, the signal system, promptly alleviate overvoltage surge that LEMP and electrostatic induction produce destruction, and then alleviate the degree of protection of overvoltage surge peripheral electronic equipment power source system, signal system.Its two, simple in structure, easy to implement, on the basis of existing arrester, earthing device, the primary coil of described high-frequency pulse transformer be series in the loop that arrester and earthing device form get final product.Its three, purposes is wide, it is all very suitable that the protection at building, wind power generation, solar power generation, naval vessel, communication equipment station or the like is connect sudden strain of a muscle.
