Abstract
The utility model discloses an induction lightning rod, which comprises an air-termination system, a down lead and a grounding body, wherein an induction ring is arranged on the lower end of the air-termination system, and is connected with a thundercloud detecting circuit, the induction ring is arranged on an insulating bracket which is fixed on the air-termination system or a metal shielding layer, a rain-proof cover is arranged on the insulating bracket, and the down lead and the outer side of a hollow magnetron are provided with metal shielding layers which are connected with the grounding body. The utility model can judge the far, near, strong or weak conditions of thundercloud before forming lightning strikes, and reduces the electromagnetic interferences of strong electromagnetic radiation generated by thunder strikes to nearby electronic facilities owing to installing the metal electromagnetic shielding layers and the magnetron. The metal electromagnetic shielding layers and the magnetron can form a magnetic path, thereby leading the down lead to have larger electric inductance, reducing the variance ratio of thunder flow, and inhibiting voltage numerical value on a ground-resistance. The rain-proof cover which is arranged on the insulating bracket can prevent the induction ring from getting wet in the rain, and increases the induction sensitivity of the induction ring to an electric field.
Description
Technical field:
The utility model relates to lightning protection, a kind of specifically lightning arrester with induction and function of shielding.
Background technology:
The form structure that existing lightning rod adopts has guiding mostly and provides thundercloud to lead discharge and back discharge channeling, and far and near power of thundercloud etc. do not had the sensing effect, thundercloud do not had shielding action by the electromagnetic interference that lightning rod interdischarge interval downlead produces yet, can not suppress discharging current, can not reduce the rate of change of electric current, be difficult to overcome the earth potential counterattack and moment strong-electromagnetic field to the destruction of electronic equipment.Publication number is that the Chinese patent of CN2692887 discloses a kind of electromagnetic-radiation-free lightning arrester, this device be at the outside of common lightning rod and downlead suit one deck or two-layer shielding iron pipe, thereby reached the effect of electromagnetic shielding; Publication number is that the Chinese patent of CN2651998 discloses a kind of lightning rod; adopted conical arrester; and the arranged outside hollow cylinder screen at downlead reaches the shielding action of reduction lightning rod to the protection thing; but above-mentioned two kinds of structures all can't be responded to the strong and weak degree of thundercloud, have still stayed potential safety hazard.
Summary of the invention:
The utility model be exactly provide at above deficiency be skillfully constructed, simple in structure, the induction lightning rod that can before thunderbolt forms, just can judge the thundercloud situation; In thunderbolt formation, reduce the rate of change of lightning current, suppress the voltage value on the earth resistance, reduce the temporary overvoltage in induction overvoltage and the circuit.
Technical solution adopted in the utility model is:
A kind ofly respond to lightning rod and comprise successively arrester, downlead and the earth electrode that connects, the lower end of arrester also is provided with inductance loop, and inductance loop is connected with the thundercloud testing circuit.
Described inductance loop is arranged on the insulating support, and insulating support tilts to be fixed on arrester or the metal screen layer.
The described downlead and the hollow magnetic tube outside also are provided with metal screen layer, and metal screen layer also is connected with earth electrode.
Described insulating support is provided with rain cover, prevents that inductance loop is soaked with rain.
The good effect that the utility model can reach is:
1, the utility model be skillfully constructed, simple in structure, easy to use, can before thunderbolt forms, judge the situation such as far away, near, strong, weak of thundercloud.
2, the installation of the utility model metal electro-magnetic screen layer and magnetic tube has reduced lightning strike and has formed the electromagnetic interference of powerful electromagnetic radiation near electronic equipment; And metal electro-magnetic screen layer and magnetic tube constitute magnetic circuit, make its downlead that bigger inductance be arranged, and reduce the rate of change of lightning current, suppress the voltage value on the earth resistance.
3, on the insulating support rain cover is set, can prevents that inductance loop is soaked with rain, improve the induction sensitivity of inductance loop electric field.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1: this induction lightning rod comprises arrester 4, downlead 6 and the earth electrode 7 that connects successively, and the lower end of arrester 4 also is provided with inductance loop 1, and inductance loop 1 is connected with the thundercloud testing circuit; Inductance loop 1 is arranged on the insulating support 2; insulating support 2 tilts to be fixed on arrester 4 or the metal screen layer 3; the downlead 6 and hollow magnetic tube 5 outsides also are provided with metal screen layer 3; metal screen layer 3 also is connected with earth electrode 7; on insulating support (2), add rain cover (8), protection inductance loop (1).Arrester 4 plays common lightning rod function, is about to the thundercloud discharge guiding to self, makes thunderbolt occur in self, makes powerful lightning current through downlead 6, releases into the earth by earth electrode 7, thereby makes protected object and inductance loop 1 exempt from direct stroke.Insulating support 2 works to support inductance loop 1 and rain cover 8, inductance loop 1 is to be used for surveying the far and near strong and weak transducer of thundercloud, with after connect the thundercloud testing circuit and cooperate and can before thunderbolt, induce the far and near strong and weak situation of thundercloud, metal screen layer 3 and be socketed in outside arrester 4 and the downlead 6 with the magnetic tube 5 that special material is made, when taking place to launch aing surprise attack on arrester 4 and the downlead 6 Electromagnetic Interference of radiation towards periphery play certain shielding inhibitory action; Simultaneously, metal screen layer 3 and magnetic tube 5 constitute magnetic circuit, make its downlead 6 that bigger inductance be arranged, and reduce the rate of change of lightning current, suppress the voltage value on the earth resistance, reduce the temporary overvoltage in induction overvoltage and the circuit.Can reduce the electric surge that forms because of thunderbolt destruction so effectively to electric equipment.
