Although it is the lightning protection measures that transmission line of electricity generally uses to set up lightning conducter and ground connection, in area with more lightning activities, thunderbolt is to make
The main reason for being tripped into transmission line of electricity.Due to lightning conducter（Including OPGW）The top of wire is erected at, generally thunderbolt can be hit
Lightning conducter or shaft tower, in most cases, resistance to thunder is horizontal to be higher than intensity of lightning, and transmission line of electricity can't trip.But thunder
The high temperature of electric arc can cause the coating for protection against corrosion localized burn of lightning conducter strands, add the risk of lightning conducter rusting broken strands broken string；
Under serious situation, thunder and lightning arc directly blows the strands of lightning conducter, and dissipate de- strands too can cause transmission line of electricity close to wire
Trip power outage；More serious situation is that lightning conducter broken string occurs in multiple loop transmission line, causes more back transmission lines
The serious consequence of tripping operation simultaneously.For the lightning conducter part corrosion defect caused by thunderbolt, cost-effective skill is also lacked at present
Art means monitor discovery in time, cause to be eventually developed to as the power outage that breaks.Allow to be found that lightning conducter is stranded in time
Defect, repairing or replacing need of work long period have a power failure, especially OPGW, and replacement cost is very big.
In the transmission line of electricity of voltage levels, the main reason for causing line tripping is shielding thunder.Shielding thunder is avoided to draw
Transmission line of electricity tripping operation is played, almost needing every Ji Ta, cost is high, fails large area at present per phase conductor all wiring arresters
Popularization and application.
To reduce the probability of happening of shielding thunder, it is to go out in recent years to install lateral lightning rod additional on the lightning conducter of transmission line of electricity
Existing technology trend.Structure is protruded by increasing the lateral needle-like of lightning conducter so that lightning conducter is more prone to form lightning leader, draws
Thunderbolt lightning conducter is led, reduces the probability of thunderbolt wire.A variety of similar technical schemes are applied on the transmission line of electricity of various regions, are obtained
Preferable anti-mine effect.But existing anti-shock arrester technology generally existing is insufficient as follows：1st, it is complicated, cost
It is high；2nd, weight is big, easily occurs to loosen sliding in the big place in lightning conducter inclination angle；3rd, lightning rod and lightning conducter contact surface are less,
Easily it is in contact a generating scaling loss lightning conducter.
The content of the invention
Present invention aims at a kind of shield line lightning rod is provided, to solve the above problems, following purpose is realized：1st, make to take shelter from the thunder
Line is easier to be formed thunder and lightning and headed on guide, reduces thunderbolt wire probability；2nd, during thunderbolt lightning conducter, guiding thunderbolt lightning rod,
The probability that thunder directly hits lightning conducter is reduced, scaling loss coating for protection against corrosion, stranded or even broken string risk when reducing lightning conducter thunderbolt；3、
Lightning current is reduced by lightning rod and the contact resistance of lightning conducter, avoids junction from being generated heat when passing through lightning current impaired；4th, tie
Structure is simply light and handy, reliability and durability, and simple installation is firm, and cost is cheap, cost-effective, is easy to be widely applied.
To achieve these goals, the invention provides one kind to protect line lightning rod, installed in the lightning-arrest of overhead transmission line
On line, including the preformed strands part on lightning conducter that is fastened, and by preformed strands perpendicular to lightning conducter bending
Extend the point discharge pin part formed.This two parts is to be formed by one whole section of strands is preformed with bending.Point discharge pin part
In transmission line of lightning strike, it is initially formed thunder and lightning and heads on guide, attracts thunder and lightning to hit point discharge pin, and pass through preformed strands
Part and the abundant rigid contact of lightning conducter, conduct lightning current, avoid connection position heating scaling loss；So as to realize reduction thunderbolt
Wire or the probability for directly hitting lightning conducter, play the effect of protection wire and lightning conducter.
Above-mentioned preformed strands are made up of single strands, or are made up of multiply strands.
When multiply strands are twisted integrated point discharge pin, point discharge pin is a tip or the branched tip of dendroid.
Above-mentioned point discharge pin is made up of the one or both ends bending extension of preformed strands.
The bending extension above lightning conducter of above-mentioned point discharge pin is formed, and two point discharge pins are in the horizontal plane to phase
The vertical lightning conducter extension of opposite direction.The bending extension above lightning conducter of point discharge pin can utilize the gravity of sophisticated lightning rod to increase
Add the twisted power of preformed strands.The vertical lightning conducter level of an at least point discharge pin stretches to the outside of transmission line of electricity.When only
When thering is one end to have sophisticated lightning rod, fixed using the frictional force of preformed strands and lightning conducter.When there is spray point at both ends, remove
Outer using preformed strands and the fixation of the frictional force of lightning conducter, they can also play a part of gravitational equilibrium, offset upset not
Equilibrant force, even if overturning, also an at least point discharge pin is towards on the outside of transmission line of electricity.
The present invention draws thunder part and preformed strands fastening part integral structure for sophisticated lightning rod, connects without bolt
Connect, will not be released because of Long-term Vibration, be not in that loose contact causes heating scaling loss lightning conducter；It is simple in construction, overall weight
Amount is light, loading will not be caused to influence on lightning conducter, can be separated by tens meter amperes and fill one；Prior art is contrasted, cost is cheap, property
