Abstract
The utility model discloses an integrated lighting protection system for power transmission line. The system comprises vertical lighting arrester disposed on top of transmission tower and series-connected with impedor; two insulated support posts disposed on top of the transmission tower and on two sides of the lighting arrester; lighting ground wire disposed on top of the two insulated support posts, erected at a direction consistent with power transmission lines below tower top, and having discharger with upward tip; conductor wire for connecting the lighting ground wire and the lighting arrestor above the impedor; and magnetic induction choke components respectively fitted outside three power transmission lines below tower top for weakening high-frequency pulse current of lighting. The magnetic induction choke is hollow cylinder with magnetic matrix and used for accommodating insulated and sealed power transmission line in its cavity. The inventive lighting protection system can effectively weaken high-frequency pulse current component generated by lighting, and avoid power frequency short circuit of power transmission line.
Description
Technical field
The utility model relates to a kind of thunder and lightning of avoiding and attacks system, exactly relates to be used for the lightning protection system of electric power transmission line.
Background technology
At present, China supports on the iron tower of high pressure overhead power line lightning conducter all is housed, but facts have proved that this lightning conducter do not stop thunderbolt harm.The puncture short that thunder and lightning causes still happens occasionally, and reason is the overvoltage that thunder and lightning produces on lightning conducter, surrounding air is punctured, and because air ionization has destroyed the facility insulation, make the short circuit of power transmission line power frequency cause the transmission line tripping operation.In order to solve this technical barrier, Chinese patent ZL99251729.X provides a kind of " the special-purpose lightning-arrest arc-extinction device of ultra-high-tension power transmission line "; by being erected at special-purpose lightning rod that the iron tower top has impedor, setting up the consistent lightning conducter that has most advanced and sophisticated discharger up of direction, realized lightning protection to the iron tower neighboring area with the high voltage transmission line direction.But,, still have to meet with the possibility that thunder and lightning attacks for the electric power transmission line that leaves the protection zone.
Summary of the invention
Goal of the invention of the present utility model is: exempt from the integrated lightning protection system that thunder and lightning attacks for power department provides a kind of ultra-high-tension power transmission line of effectively protecting.
Goal of the invention of the present utility model realizes by implementing following technical scheme:
Electric power transmission line integrated lightning protection system, include: be erected at the special-purpose vertically lightning rod that the iron tower top is serially connected with impedor L, be arranged on the lightning rod both sides, the two piece supports insulative pillars of device on cat head, be contained in two and thoroughly do away with edge pillar top, it is consistent with the high voltage transmission line direction of iron tower top underlying that it sets up direction, the lightning conducter that has most advanced and sophisticated discharger up, and the lightning rod on lightning conducter and impedor top fuses by lead, it is characterized in that: at the A of iron tower top underlying, B, on three high voltage transmission lines of C, be respectively installed with the magnetic induction flow plug of cutting down the thunder and lightning high-frequency pulse current.
Additional technical feature is: cut down the magnetic induction flow plug of thunder and lightning high-frequency pulse current, be the hollow cylinder that magnetic material is made matrix, and be packaged with the high voltage transmission line that is insulated sealed envelope in this hollow cylindrical cavity.
Advantage of the present utility model is: in case power transmission line is struck by lightning, when the lightning current that has been excited reaches the magnetic induction flow plug along this power transmission line, its high-octane high-frequency pulse current composition is by the powerful weakening of this flow plug, and finally be attenuated on transmission line, can not cause the power frequency short circuit that causes transmission line because of air ionization.Therefore, with Chinese patent ZL99251729.The lightning conducter device of X is compared, and this integrated lightning protection system has enlarged the strick precaution scope to thunder and lightning greatly.
