Abstract
The invention relates to a foldable variable-angle lightning receptor. The foldable variable-angle lightning receptor comprises a fixed base and a lightning rod fixed to the fixed base, wherein the fixed base comprises a base strip-shaped steel plate, the base strip-shaped steel plate is provided with universal hook-shaped bolts and a fan-shaped steel plate perpendicularly welded to the base strip-shaped steel plate, and the lightning rod is fixed to the fan-shaped steel plate. According to the foldable variable-angle structural design, the protection range of the lightning receptor is changed by adjusting the angle of the movable lightning rod so that poles with different types can be located in the effective protection range of the lightning receptor. Because the multi-tip structural design of a bird repellent is introduced to the tip of the lightning receptor, point discharge and lightning attracting effects can be improved, and the possibility that protected objects are directly suffered from lightning is reduced. Because the two universal hook-shaped bolts are connected with a pole, the foldable variable-angle lightning receptor can be fixedly connected with steel angles with different directions and types and is convenient and reliable to install and use.
Description
Technical field
The present invention relates to a kind of collapsible variable angle arrester lightning protection device.
Background technology
Thunderbolt is for a long time a major reason that causes transmission line malfunction tripping operation always, and particularly summer, mountain area thunder and lightning was multiple, and lightning stroke trip fault more easily occurs.In each electric pressure, 35kV circuit lightning fault is maximum, substantially accounts for the more than 50% of whole damage to crops caused by thunder.
By all 35kV overhead line structures that suffered lightning fault are in recent years analyzed, discovery cause the reason of lightning stroke trip mainly concentrate on following some: (1) shaft tower in mountain top, the higher hillside of drop or there is no the open ground of other higher building bodies around mountain valley etc., easily draw thunder; (2) lightning protection configuration is weak, particularly 35kV overhead line structures do not have lightning conducter or lightning protection angle too large, generally exceed 25 °, be all greater than the design protection angle of shaft tower lightning conducter in state's net modular design; (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 likely to form counterattack.By the above analysis of causes, known to address this problem at present the most effective and feasible approach be exactly to take simple way to reduce the lightning protection angle of 35kV circuit.We have carried out a large amount of data consultations and market survey thus, find traditional to set up lightning conducter, the long transformation that is not suitable for old circuit of the method construction periods such as arc suppression coil is installed, and the feature such as the product ubiquities such as novel dissipation array are expensive, range of application is little is not suitable for large area track remodelling.Therefore for the actual demand of 35kV line thunder protection work, a kind of simple and reliable, low price of development, the lightning protection thunder carrying-off device that convenient construction can large area be installed and used is again very necessary.
Summary 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, adopts pure Design of Mechanical Structure, simple and reliable, is easy to carry, and is easy to install, and cost is low, highly versatile, widely applicable.
Collapsible variable angle arrester provided by the present invention, comprise firm banking and attracting thunder needle, attracting thunder needle is fixed on firm banking, described firm banking comprises base bar steel plate, universal hook bolt is installed on base bar steel plate and is gone back fan-shaped steel plate simultaneously, fan-shaped steel plate is vertically welded on base bar steel plate, and attracting thunder needle is fixed on fan-shaped steel plate.Universal hook bolt is directly held and is connected on firm banking bar steel plate, and hook end hook is lived shaft tower angle bar, and universal hook design can be reliably fixing with the angle bar of various directions, angle, convenient installation.
On described fan-shaped steel plate, be provided with the relative U-shaped bayonet socket of many groups, attracting thunder needle is by being fixed on adjusting angle on U-shaped buckle.
Described attracting thunder needle comprises fixing attracting thunder needle and movable attracting thunder needle, and fixing attracting thunder needle is fixed on arrange vertical with fan-shaped steel plate on base bar steel plate, and movable attracting thunder needle is many group symmetrical structures, and movable attracting thunder needle is fixed by embedded slide bolt and U-shaped buckle.
Described attracting thunder needle has electric discharge spine and attracting thunder needle body, and discharge tip is stung by being 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 rotate freely by rotating shaft, can overlap and also can launch as required with fixing attracting thunder needle.Coordinate U-shaped bayonet socket to be fixed simultaneously, realize variable angle structure, can reduce according to the setting angle of different shaft tower model adjusting activity attracting thunder needles the lightning protection angle of shaft tower, make the lightning protection angle of various model shaft towers all can be in effective protection range.
The radial spine structure that bird-resistant is grabbed in radiation can strengthen point discharge and draw thunder effect, reduces thunder and lightning and attacks protected object probability directly.
Attracting thunder needle divides fixed and movable two kinds, and one of fixing attracting thunder needle, perpendicular to ground, is bolted on the middle part of base fan-shaped steel plate; Preferably two of movable attracting thunder needles, be installed on fixing attracting thunder needle both sides and in same covering of the fan, utilize embedded slip in it tight a bolt with fan-shaped steel plate on U-shaped bayonet fittings regulate movable attracting thunder needle setting angle, while installation and fixing dissipation array fold, convenient transport with carry.The present invention adopts collapsible variable angle structural design, and adjustable attracting thunder needle setting angle is suitable for the electric power line pole tower of the various models of all regions, and line thunder protection level is improved at the lightning protection angle that can obviously reduce shaft tower.
Operation principle:
This device is installed on head of mast, is reliably connected with tower body and earth electrode by base.Described in when installation, install that attracting thunder needle is fan-shaped to be ensured in same plane with cross arm of tower; fixing attracting thunder needle is positioned at middle and the highest; the V-shaped cross-arm top, both sides that lays respectively at of movable attracting thunder needle; and according to the setting angle of different tower adjusting activity attracting thunder needles and then change lightning protection angle, so that dual-side phase conductor all can be in effective protection range.Attracting thunder needle attracts the thundercloud in shaft tower overhead to discharge to it, then by the earthing device of shaft tower itself, lightning current is leaked into the earth, reduces the probability of thunderbolt tower and conductor.
The invention has the beneficial effects as follows:
(1) collapsible variable angle structural design, the angle of adjustable attracting thunder needle changes the protection range of arrester, makes the shaft tower of different model all can be in its effective protection range.
(2) many sharp thorns structural design of bird-resistant is used at attracting thunder needle tip, can strengthen point discharge and draw thunder effect, reduces thunder and lightning and attacks protected object probability directly.
(3) adopt two universal hook bolts to be connected with shaft tower, can be connected and fixed with the angle steel of various directions, pattern, easy to install reliable.
