Abstract
A lightning arrester relates to a lightning protection product. The lightning arrester comprises a metal housing which is provided end covers at both ends. A socket is fixed at each end cover. A shielding coil and a voltage-sensitive resistor are connected between the core wires of two sockets in the metal housing. The sockets are provided with connecting plugs with same axis. The induced charges of lightning can be transferred in time thereby preventing the damage to the device.
Description
Technical field
The utility model belongs to and relates to a kind of lightning arrester.
Background technology
Conventional lightening arresting method is to utilize element parallel connections such as gas discharge tube and piezo-resistance on the line, realizes taking shelter from the thunder.Piezo-resistance needs certain starting resistor could produce the drastic change of impedance, and needing many situation thunders and lightnings is to enter with the form of low-voltage with big electric current, so there is the possibility that does not respond in lightning protection system.And lightning stroke process is an extremely short process, requires the piezo-resistance reaction to want fast, and so in fact the piezo-resistance response is gone up and be unhappy, and the inductance of transmission line also makes the time slack-off.In fact, this lightening arresting method essence is a kind of shunting mode, and shunting effect is undesirable, thereby lightning protection effect and bad.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of new leakage conductor is provided.This lightning arrester can in time be transferred to the thunder and lightning static charge inducing on lightning rod or the lightning conduction, thereby avoids the damage to equipment.
Structure of the present utility model is: a kind of lightning arrester, comprise metal shell, the two ends of metal shell are provided with end cap, are fixed with socket at end cap, be connected with shielded coil and piezo-resistance between the inherent two socket heart yearns of metal shell, socket is provided with the plug of band coaxial line.
Metal shell links to each other with the shielding conductor of two coaxial lines, article two, in the coaxial line is the coaxial line of terminal heart yearn and shielding conductor short circuit, another is the open circuit coaxial line of terminal heart yearn and shielding conductor open circuit, and two coaxial lines connect with the communication interface that being connected of metal shell adopts standard.
The effect of described piezo-resistance is in order to block direct connection the between circuit and the ground.
Advantage of the present utility model: the open circuit coaxial line communicates with protection circuit, and short-circuit coaxial line links to each other with lightning rod.Can be shifted timely the lightning induction electric charge, thereby be avoided damage equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
1 is metal shell, the 2nd among the figure, end cap, the 3rd, socket, the 4th, shielded coil, the 5th, piezo-resistance.
Embodiment
As shown in Figure 1, a kind of lightning arrester comprises metal shell 1, the two ends of metal shell 1 are respectively equipped with end cap 2, be fixed with socket 3 on the end cap 2 at two ends, be connected with shielded coil 4 and piezo-resistance 5 between metal shell 1 inherent two sockets, 3 heart yearns, socket 3 is provided with the plug of band coaxial line.
Metal shell links to each other with the shielding conductor of two coaxial lines, article two, in the coaxial line is the coaxial line of terminal heart yearn and shielding conductor short circuit, another is the open circuit coaxial line of terminal heart yearn and shielding conductor open circuit, and two coaxial lines connect with the communication interface that being connected of metal shell adopts standard.
