Description
Technical field
The present invention relates to a kind of collapsible variable angle arrester lightning protection device.
Background technology
Thunderbolt for a long time always causes the major reason that transmission line malfunction trips, particularly summer mountain area thunder
Electricity is multiple, it is easier to which lightning stroke trip failure occurs.In each electric pressure, 35kV circuits lightning fault at most, accounts for complete substantially
More than the 50% of portion's damage to crops caused by thunder.
By being analyzed to the 35kV overhead line structures for being subjected to lightning fault all in recent years, discovery causes lightning stroke trip
The reason for be concentrated mainly on it is following some：（1）Shaft tower in the higher hillside of mountain top, drop or does not have which around mountain valley etc.
The open ground of his higher building body, easily draws thunder；（2）Lightning protection configuration is weak, and particularly 35kV overhead line structures do not have lightning conducter
Or lightning protection angle is too big, generally more than 25 °, the design protection angle of shaft tower lightning conducter in state's net modular design is all higher than；（3）
Some pole tower ground resistances of mountain area are higher, and resistance is bigger than normal, and to cause thunder and lightning to lead passage off not smooth, causes thunderbolt to be likely to form counterattack.
Understand that it is exactly to take simple method to reduce to solve the most effective feasible way of this problem at present by the above analysis of causes
The lightning protection angle of 35kV circuits.Thus substantial amounts of data consultation and market survey are We conducted, it is found that traditional erection keeps away
The method construction period length such as thunder line, installation arc suppression coil are not suitable for the transformation of old circuit, and the product such as new dissipation array is general
Store-through it is expensive, range of application is little the features such as, be not suitable for large area track remodelling.Therefore 35kV line thunder protection works are directed to
The actual demand of work, develops a kind of simple and reliable, low price, but convenient construction can the lightning protection installed and used of large area draw thunder dress
Put very necessary.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of collapsible variable angle arrester lightning protection device, using purely mechanic
Structure design, it is simple and reliable, it is easy to carry, it is easy to install, it is low cost, highly versatile, widely applicable.
Collapsible variable angle arrester provided by the present invention, including firm banking and attracting thunder needle, attracting thunder needle are fixed on
Determine on base, described firm banking includes base bar steel plate, universal hook bolt is installed while also on base bar steel plate
Fan-shaped steel plate, fan-shaped steel plate are vertically welded on base bar steel plate, and attracting thunder needle is fixed on fan-shaped steel plate.Universal hook bolt
Straight end is connected on firm banking bar steel plate, and hook end hooks shaft tower angle bar, and universal hook design can be with various directions, the angle of angle
Iron is reliably fixed, convenient to install.
Multigroup relative U-shaped bayonet socket is provided with described fan-shaped steel plate, attracting thunder needle is adjusted by being fixed on U-shaped buckle
Section angle.
Described attracting thunder needle includes fixing attracting thunder needle and movable attracting thunder needle, and fixed attracting thunder needle is fixed on base bar steel plate
It is vertically arranged with fan-shaped steel plate, movable attracting thunder needle is multigroup symmetrical structure, and movable attracting thunder needle is by embedded slide bolt and U-shaped
Buckle is fixed.
Described attracting thunder needle has electric discharge spine and attracting thunder needle body, and discharge tip transfixation is crossed and is bolted on attracting thunder needle
Bodies top.
Described movable attracting thunder needle bottom is fixed on fan-shaped steel plate by rotating shaft, and movable attracting thunder needle can pass through rotating shaft freedom
Rotation, you can overlap also dependent on needing to launch with fixed attracting thunder needle.Coordinate U-shaped bayonet socket simultaneously to be fixed, it is real
Existing variable corner structure, can reduce the lightning protection angle of shaft tower according to the setting angle of different shaft tower model regulation activity attracting thunder needles,
The lightning protection angle of various model shaft towers is made to can be in the range of effective protection.
The radial spine structure of bird-resistant is grabbed in radiation can be strengthened point discharge and draw thunder effect, reduce thunder and lightning direct attack and protected
Shield thing probability.
Attracting thunder needle is divided to fixed and movable two kinds, fixed attracting thunder needle one, perpendicular to ground, is bolted on base fan
The middle part of shape steel plate；Movable attracting thunder needle preferably two, is installed on fixed attracting thunder needle both sides and in same covering of the fan,
Tighten U-shaped bayonet fittings on bolt and fan-shaped steel plate to adjust movable attracting thunder needle established angle using the embedded slip in which
Degree, is folded with fixed dissipation array when not installing, convenient to transport and carry.The present invention is set using collapsible variable corner structure
Meter, can adjust attracting thunder needle setting angle, is suitable for the electric power line pole tower of the various models of all regions, can substantially reduce the anti-of shaft tower
Thunder shielding angle, improves line thunder protection level.
Operation principle：
This device is installed on head of mast, is reliably connected with tower body and grounding body by base.During installation, described device is drawn
Thunder pin is fan-shaped to be ensured in the same plane with cross arm of tower, and fixed attracting thunder needle is located at middle and highest, V-shaped point of movable attracting thunder needle
Above the cross-arm of both sides, and the setting angle according to different tower regulation activity attracting thunder needles and then lightning protection angle Wei Yu not be changed,
So that two side phase conductors are can be in the range of effective protection.Attracting thunder needle attracts the thundercloud in shaft tower overhead to discharge which, then
Lightning current is leaked into by the earth by the earthing or grounding means of shaft tower itself, the probability of thunderbolt shaft tower and wire is reduced.
The invention has the beneficial effects as follows：
（1）Collapsible variable angle structure design, the angle of adjustable attracting thunder needle changing the protection domain of arrester,
The shaft tower of different model is made to can be in the range of its effective protection.
（2）Attracting thunder needle tip borrows many sharp thorn structure designs of bird-resistant, can strengthen point discharge and draw thunder effect, subtract
Few thunder and lightning attacks protected object probability directly.
（3）It is connected with shaft tower using two universal hook bolts, can be fixed with the Bolted angle connection of various directions, pattern, is installed
It is easy to use and reliable.
