Abstract
The utility model provides three-dimensional closed type device for preventing lightning shielding failure of a high voltage power transmission line, which is formed by erecting a row of tubular carbon fiber lightning shielding rods along the transverse horizontal direction of lightning shielding wire trend in a lightning shielding failure dangerous zone, wherein the rods are parallelly arranged at intervals and are strong in bending resistance and good in friction resisting capability, corrosion resistance, current impact resisting capability and aging resistance. Each carbon fiber lightning shielding rod is integrally composed of a 'horizontal section' and a 'vertical section', one of nearby lightning shielding wires at two ends of the 'horizontal section' extends horizontally and outward for 2-20 meters, and the 'vertical section' extends vertically and downward to be grounded, thereby forming a three-dimensional closed type lightning shielding protective grid cover which fully seals high voltage power transmission line exposed arcs in the lightning shielding failure dangerous zone. Due to the fact that the three-dimensional closed type lightning shielding protective grid cover seals the exposed arcs, high voltage power transmission lines are protected effectively, and accordingly trip-out rate of the lightning shielding failure can be reduced remarkably.
Description
Technical field
The utility model relates to the device that a kind of ultra-high-tension power transmission line prevents thunderbolt, is used for high pressure/UHV transmission line, and particularly the thunderbolt of shaft tower napex exposes the device that arc effectively protects.
Background technology
Damage to crops caused by thunder is the principal element that influences China's electric power netting safe running.The ultra-high-tension power transmission line tripping operation accident that causes of thunderbolt accounts for circuit 70% of the number of times that always trips according to statistics.China's practical operating experiences shows that 500kV superhigh pressure and above UHV transmission line tripping operation mainly are caused by thunderbolt.Superelevation/UHV transmission line is owing to the insulation distance long enough on the one hand, and the line insulation level is very high, and counterattack can not cause flashover to insulator.On the other hand; Because height, material, electrical structure and the ground connection situation of shaft tower; Making shaft tower and near zone is that thunder and lightning provides the discharge channel more better than other position, often forms the hazardous area of triggered lightning shielding more easily than other zone, is called for short the shielding hazardous area.Countries in the world operating experience shows that also thunderbolt is the one of the main reasons of transmission line tripping operation.
To the guard technology means in shielding hazardous area, mainly be lightning rod to be installed and to be set up lightning conducter at present at cat head.Because high-voltage transmission line towers is the lightning conducter structure, inevitably have the exposure arc that partly exposes guide's thunderbolt.Through transforming lightning conducter, reduce shielding angle and can reduce to be struck by lightning and expose arc and reduce the risk of shielding failure of thunder and lightning.Japan's UHV transmission line and 500KV circuit all adopt negative shielding angle, and its thunderbolt rate is starkly lower than other country of the world.But, be not all the suit technological transformations of lightning conducter of all transmission lines, both made transformable transmission line, also can't eliminate thunder and lightning fully and expose arc.Therefore, transform the method that lightning conducter reduces shielding angle, tight, complete protection can not be provided the transmission line in the shielding hazardous area.
Before the utility model proposes, to the shielding hazardous area, also do not eliminate the correlative protection product that thunder and lightning exposes arc both at home and abroad, this also is that thunderbolt causes the high all the time major reason of transmission line tripping operation accident.
Summary of the invention
The goal of the invention of the utility model is: for the user provides ultra-high-tension power transmission line the three-dimensional closed device that prevents thunderbolt; The thunder and lightning that adopts this device can effectively eliminate on the ultra-high-tension power transmission line exposes arc; Cut off the thunderbolt channel; Significantly reduce the thunderbolt rate, can realize effectively protection, thereby reduce the tripping rate with lightning strike of ultra-high-tension power transmission line greatly the ultra-high-tension power transmission line in the shielding hazardous area.
The goal of the invention of the utility model realizes through implementing following technical proposals:
