The utility model content
The purpose of this utility model is to improve on the structure of existing lightning rod, and a kind of bypass type demagnetization arc extinguishing lightning rod is provided.
Bypass type demagnetization arc extinguishing lightning rod of the present utility model has the thunder and lightning arrester, lightning-arrest tower body of metal and down conductor system, the lightning-arrest tower body of described metal is erect setting and is had the lightning-arrest tower body top of metal and the lightning-arrest tower body bottom of metal, described thunder and lightning arrester is fixedly mounted on the lightning-arrest tower body top of metal, described down conductor system one end is connected with thunder and lightning arrester conduction, the described down conductor system other end extends to the lightning-arrest tower body bottom of metal, it is characterized in that having electric spark isolating metal reflector net between the lightning-arrest tower body of described thunder and lightning arrester and metal, described electric spark isolating metal reflector net is fixed and is conducted electricity with the lightning-arrest tower body of metal and is connected, described electric spark isolating metal reflector net and the insulation of thunder and lightning arrester, has part flow arrangement between described thunder and lightning arrester and down conductor system one end, described thunder and lightning arrester is connected by the part flow arrangement conduction with down conductor system one end, described down conductor system is made of at least three down conductor system unit, and described adjacent down conductor system has the gap between the unit.
The lightning-arrest tower body that the lightning-arrest tower body of metal described in the utility model promptly adopts existing metal material to make is as the lightning-arrest tower body of ferrous metal, the lightning-arrest tower body of steel metal or the lightning-arrest tower body of copper metal or the like.The existing metal material of the same employing of the isolating metal of electric spark described in the utility model reflector net is made, and isolates steel metallic reflection net or electric spark isolation copper metallic reflection net or the like as electric spark isolation ferrous metal reflector net, electric spark.The multichannel syndeton (being similar to this multichannel of wiring board Electricity Federation exchange device) that part flow arrangement described in the utility model is promptly made of existing metal material, the just electric shunt of common indication in the electricity.
The isolating metal of electric spark described in the utility model reflector net is fixing to be fixed and conducts electricity and be connected with the metal tower body of taking shelter from the thunder, be meant that promptly described electric spark isolating metal reflector net is when the thunder and lightning arrester is struck by lightning, the electric spark that thunder and lightning produces can be stopped, and eliminate issuable electric arc by the lightning-arrest tower body of metal that conduction connects.
The arrester of thunder and lightning described in the utility model is fixedly mounted on the lightning-arrest tower body top of metal, described down conductor system one end is connected with thunder and lightning arrester conduction, be meant that promptly the thunder and lightning arrester is except with down conductor system conduction is connected, with other device insulation, as with the lightning-arrest tower body insulation of metal or with the lightning-arrest tower body of metal on other external device (ED)s insulation of installing additional or the like.
Down conductor system described in the utility model is made of at least three down conductor system unit, be meant that promptly described down conductor system both can be that three down conductor system unit constitute, it also can be the down conductor system unit formation more than three, certainly, the down conductor system unit is many more, when the thunder and lightning arrester was struck by lightning, the lightning current that each down conductor system unit is carried was just low more, and the corresponding harm that brings is just more little.
Adjacent down conductor system described in the utility model has the gap between the unit, is meant promptly between a plurality of down conductor systems unit that remainder insulate mutually except part flow arrangement place conduction connects.That is to say that down conductor system of the present utility model unit adopts multipoint earthing.Described down conductor system unit can make of the High-Voltage Insulation wire rod, like this, just can effectively guarantee the shunting effect to lightning current between the described down conductor system unit.
In order to allow bypass type demagnetization arc extinguishing lightning rod of the present utility model better bring into play usefulness, the lightning-arrest tower body of described metal can adopt the existing electromagnetic-field-shielded tower body of multichannel, allow the down conductor system unit pass metal tower body cable shielding pipeline on the lightning-arrest tower body of metal, down conductor system unit to every road earial drainage all carries out electromagnetic-field-shielded, can make thunder and lightning in the process on the ground of releasing through the down conductor system unit, reduce the electromagnetic field radiation ability to greatest extent, thereby reduce thunderbolt secondary breakdown strength better effectively, guarantee lightning protection effect.
Compared with the aforementioned existing similar products, bypass type demagnetization arc extinguishing lightning rod of the present utility model can be shunted lightning current and release into ground, can reduce the energy of lightning current greatly, prolong the lightning rod life-span, reduce thunderbolt secondary breakdown strength effectively, guarantee lightning protection effect and eliminate safe hidden trouble.
