Description
Technical field
The utility model relates to the livewire work field, builds the nest masking device in particular to a kind of anti-bird of distribution line isolating switch.
Background technology
Birds are built nest at distribution line and cause distribution line failure easily, and the safe operation of serious threat circuit has caused enormous economic loss to electric power enterprise and user.At present, it is varied that the anti-bird of using at the 10kV distribution line is built the nest measure, influenced by various factors, and effect is very little, and the progress of making a breakthrough property is failed in preventing and controlling all the time.Power supply enterprise is in order to reduce bird pest to the influence of line security operation simultaneously, strengthen operational management, increase and make an inspection tour density, drop into a large amount of manpower and materials and remove Bird's Nest, though obtained certain effect, also brought greatly seasonal work pressure to the operations staff, simultaneously in the process of removing Bird's Nest, also easily cause line fault, for hidden danger has been buried in the line security operation.
The technical scheme of prior art and shortcoming:
1, pneumatic type bird-scaring unit: the principle that keeps in dark place, fears look according to birds, the employing natural wind is power, drive interruption reverberation that the chromium plating stainless steel reflecting piece on the wind bowl turning cylinder sends with atwirl wind bowl and reach and drive the bird effect, prevent the purpose that birds are nested, have a rest at the overhead line structures dangerous position.The pneumatic type bird-scaring unit plays certain effect for preventing that birds dangerous position on tower from nesting, the installation but this bird-scaring unit need have a power failure, and do not having in the weather of wind, the wind bowl can't rotate, and bird-scaring unit also loses flush, drives the usefulness of bird.Phenomenons such as after moving certain hour simultaneously, the partial devices accessory corrosion, weathering occur, falls to take off, breakage, thus lose bird-scaring unit drive the bird effect, near the residential block, easily cause light pollution.
2, supersonic wave bird driving device: this device comprises parts such as solar panel, radar, eagle model, loudspeaker, adopt solar powered, storing birds in advance, to die in an accident, meet natural enemy be the warning of sending, sound of call for help etc., under normal circumstances be in mute state, in case ultrasonic sensing is to there being small bird to fly when near, the sound that will give a warning is driven birds and is perched at shaft tower, reduce the possibility that birds are nested, prevented that birds from nesting in the deathtrap.This device need to have a power failure is installed, and has played remarkable effect at the application initial stage to preventing that birds from nesting at the shaft tower dangerous position, but birds have been accustomed to eagle model and the cry of bird-scaring unit after using a period of time, and the dangerous position that begins again on electric pole is nested.Can not effectively frighten for a long time and expel birds, near the residential block, easily cause noise pollution.
3, bird-resistant: solve the difficult problem that birds are nested at the shaft tower dangerous position, be on the cross-arm that is placed on the high-voltage transmission line pole tower insulator limit, prevent that birds from nesting and stop for a long time at cross-arm, steel wire generally adopts the steel wire of 2 millimeters of diameters, adopt intermediate conveyor screw formula structure, increase elasticity, birds can't be stopped and fly away, from the effect of rear defence bird is installed, this device can prevent effectively that bigger birds from stopping in the string cross-arm position of dangling and have a rest, the erosion of can withstand long term exposure open-air sleet frost dirt has the long-term bird effect of driving.But this device needs to have a power failure and installs, and bird-resistant is metallic conductor, the bird thorn needs to form the thorn hat with specific density and area, because 10kV distribution line cross-arm, electric pole and lead space are less, do not satisfy safe distance relatively, if reduce the length of bird-resistant, drive the bird function with what reduce bird-resistant.
4, anti-bird pest cross-arm: by special structural design, make bird not possess the condition of building nest, anti-bird pest effect is remarkable.Owing to be the product of new research and development, do not come into operation on a large scale, be used for newly-built 10kV distribution line more, as the circuit that puts into operation is changed, then need a huge sum of money and need large tracts of land, the long-time power failure.
5, other anti-bird pest measures among the people: as in position hanging plastic bottle, plastic sack even birds corpse.The installation that need have a power failure of this type of way, and hang measures such as plastic bottle, plastic sack even birds corpse, can only play the flush effect in a short time.
