Shielding conductor is used for the lightning current that overhead ground wire is walked around in interception, and the heavy current that produces when playing the shunting thunderbolt can avoid thunder and lightning directly to puncture built on stilts lightning conductor, plays shielding action.Shielding conductor adopts eight, and per four is one group: it can fully shunt thunder-strike current.Described shielding conductor adopts carbon fibre composite to make, and has the characteristics such as high temperature resistant, frost resistance, acid-mist burn into frost resistance performance are good.
The utility model adopts thunder and lightning signal receiver output phase line be connected with earth connection method and the shielding action by shielding conductor; the heavy current that moment produces in the time of can effectively receiving and catch strong thunderbolt; be connected the output phase line with the thunder and lightning signal receiver by shielding conductor and directly connect earth connection and shaft tower; but moment leaks into electric current among the earth; thereby effectively protected wire; thoroughly avoid overhead transmission line to run into bad weather and formed thunderbolt and the short circuit or the trip accident that cause, thereby guaranteed safe, the reliable and stable operation of overhead transmission line.
Tower comprises tower bar cross-arm anchor clamps and the hanging wire metal compounds anchor clamps that connect up and down to connecting metal fixture anyhow, and it is the taper wire clamp that described hanging wire connects metal fixture.
Described overhead ground wire fixing metal connector adopts Z-shaped wire clamp, material selection 316L stainless steel.
It is the sealings of 868 special epoxy resins that described lightning strike signals receiver casing adopts model, can play waterproof, the effect such as anti-spillage, antifreeze.
The beneficial effects of the utility model:
The output phase line of the thunder and lightning signal receiver method that is connected with ground wire is adopted in the utility model design; and the shielding action that produces by eight shielding conductors; can effectively catch the heavy current that moment in when thunderbolt produces, thereby lightning conducter and wire are effectively protected under the moment heavy current surge.Directly be connected with ground wire by the output phase line that adopts respectively the thunder-lightning signal receiver simultaneously, and the shielding action of shielding conductor, the heavy current that moment produces in the time of can making thunderbolt incorporates in the earth immediately and is fully discharged.Avoid and prevent short circuit that overhead transmission line is struck by lightning to be caused tripping operation, guaranteed the safe and stable operation of overhead transmission line.That the utility model also has is simple in structure, easy for installation, maintenance cost is low, the characteristics such as safe and reliable.
