Abstract
The utility model relates to a lightning arrester which is provided with a series beam and a cross-beam on the tower top of the rod of the transmission line. 3 to 50 vertical and upward cross-shaped needle bars are arranged on the series beam and the cross-beam. A cross-shaped needle cross-beam is respectively arranged at the head of both ends. A group of main and auxiliary lightning arresting needles are respectively arranged at the cross-shaped end point of the needle bar. The installation of the needle bar is based on the distribution of the electric field of the thunder cloud. The middle part is high and two ends are gradually changed and the top is curved. The earth contact connecting line on the series beam and the cross-beam is led into the ground. The utility model only uses one series beam and two cross-beams and has compact structure. The lightning arrester can be used for the 35-330 kv transmission line at any place. The lightning arrester can evenly reduce 60% lightning trip rate and lightning accident rate.
Description
The utility model belongs to the lightning proof class of ultra-high-tension power transmission line.
Up to now, both at home and abroad on the ultra-high-tension power transmission line of 35-750kv, still widely used be " lightning conducter ", it is contained in above the transmission line usually.The shielding angle of lightning conducter generally only is about 25 °; shield ranges to lead is little; the suffered thunderbolt in head of mast accounts for about 40% of thunderbolt in addition; thereby when imperfect earth or earth resistance are too high; will too high lightning stroke trip and lightning strike accident occur because of direct attack, shielding, counterattack make ultra-high-tension power transmission line, make power failure.
" conductor display type dissipation array " (publication number 1067532, open day 921230), it is main and auxiliary prevention eliminating needle to be installed in walk crosswise on the dress pin spare, forms single array, two arrays, the dissipation array of array in pairs.Its concrete structure is: walk crosswise dress pin spare and be installed on the cross-arm two ends of electric power line pole tower, main prevention eliminating needle is installed in to be walked crosswise on the dress pin spare, auxilliary prevention eliminating needle square crossing is arranged on the main prevention eliminating needle, and the left and right dress pin spare of walking crosswise goes into ground by the down conductor of ground connection connecting line.Though it can make the tripping rate with lightning strike of the ultra-high-tension power transmission line of being adorned and rate of failure reduce, because its " array " is oversize, structure is insecure, should not and repeat the ice formation and adopt in violent typhoon.
The purpose of this utility model is the problem that exists at the array type dissipation array, is intended to design a kind of sound construction, long service life, the effective dissipation array of the thunder that disappears.
The purpose of this utility model realizes in the following manner, and the load type dissipation array that crouches is installed string beam 3 on electric power line pole tower 1, will go here and there, pitch beam and be fixedly mounted on the shaft tower top.On the string beam the criss-cross shank 2 of 3-50 root is installed then, criss-cross end points has 4,3 * 4 auxilliary prevention eliminating needles 5 of 3 main prevention eliminating needles respectively.Be installed in the shank 2 on the string beam, middle height, both sides are step-down gradually, and this top of body is curved.String, the fork down conductor 6 on the beam goes into ground along shaft tower.
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, string, fork beam 3 are installed on electric power line pole tower 1, according to required how many main and auxiliary prevention eliminating needle logarithms that refill, the string beam is changeable, is generally 3-16m, fork beam length 0,3-6m.Shank can adopt the 3-50 root, adorn one group of main and auxiliary prevention eliminating needle at the cross end points on every shank top, prevention eliminating needle is made with the corrosion-resistant high-strength aluminium of high-quality, copper alloy and stainless steel material etc., main prevention eliminating needle shank length 0,1-2m, auxilliary prevention eliminating needle shank length 1-100cm, the pin end is 3 ° of-30 ° of cone angles.
The utility model shank 2 is that the characteristic distributions according to the thundercloud electric field is installed on the string beam, and middle shank height, two ends are step-down gradually, and top is curved, pacifies prevention eliminating needle above again, and every pair of prevention eliminating needle all can be played one's part to the full.
The utility model only adopts a string beam, two fork beams, and top is criss-cross shank, radical is the 3-50 root, total compactness, firm.Be added in string beam two ends again cross fork beam 3 also is housed, whole dissipation array is crouched sleep on the shaft tower top, thereby constitute " the load type crouches ", make the utility model in officely where distinguish use, both made in violent typhoon and repeat the ice formation and all can use.After installing firmly, useful life is more than 15 years.Down conductor can directly be connected on the string fork beam.Downlead 6 is contained on the line pole tower, and the downlead sectional area is greater than 25mm
2
Adopt the utility model can eliminate and reduce, can eliminate and limit the thunderbolt that caused by the downward guide of thundercloud and the current strength of its main discharge reliably by the electric power line pole tower thunderbolt that the guide caused that makes progress.The utility model on average can reduce tripping rate with lightning strike and stroke-incidence rate about 60% in the operation of 35-330kv transmission line, makes the anti-lightning strike level of ultra-high-tension power transmission line obtain big spoke degree raising.
Claims (3)
1, load type dissipation array for sleeping in, it is characterized in that at electric power line pole tower (1) string beam (3) installation 3-50 root top on string, fork beam being installed upward is criss-cross shank (2), criss-cross end points is equipped with 1 pair of main and auxiliary prevention eliminating needle (4), (5) respectively, be positioned on high in the middle of the shank (2) of string on the beam, both sides step-down gradually, two ends also has cross fork beam (3), whole dissipation array top is curved, and the ground connection connecting line on the string fork beam is through lead-in (6) and ground connection after the original downlead of shaft tower is connected.
