Description
Technical field
The present invention relates to livewire work field, the anti-bird in particular to a kind of distribution line isolating switch builds nest masking device.
Background technology
Birds are built nest and easily cause distribution line failure on distribution line, the safe operation of serious threat circuit, cause huge economic loss to electric power enterprise and user.At present, it is varied that the anti-bird that 10kV distribution line uses builds nest measure, affects by various factors, and effect is very micro-, and the progress of making a breakthrough property is failed in preventing and controlling all the time.The simultaneously impact that line security run in order to reduce bird pest of power supply enterprise, strengthen operational management, increase and make an inspection tour density, drop into a large amount of manpower and materials and remove Bird's Nest, although achieve certain effect, also bring greatly seasonal work pressure to operations staff, simultaneously in the process removing Bird's Nest, also easily cause line fault, bury hidden danger for line security runs.
The technical scheme of prior art and shortcoming:
1, pneumatic type bird-scaring unit: the principle of the look that keeps in dark place according to birds, fears, employing natural wind is power, the interruption reverberation driving the chromium plating stainless steel reflecting piece on wind bowl turning cylinder to send with atwirl wind bowl reaches and drives bird effect, prevents the object that birds are nested at overhead line structures dangerous position, have a rest.Pneumatic type bird-scaring unit plays certain effect for preventing birds dangerous position on tower from nesting, the installation but this bird-scaring unit need have a power failure, and in the weather not having wind, wind bowl cannot rotate, and bird-scaring unit also loses flush, drives the usefulness of bird.Run after certain hour, the phenomenons such as partial devices accessory occurs corrosion, weathering, falls off, damaged simultaneously, thus lose the effect on driving birds of bird-scaring unit, for residential neighborhood, easily cause light pollution.
2, supersonic wave bird driving device: this device comprises the parts such as solar panel, radar, eagle model, loudspeaker, adopt solar powered, store that birds are wrecked, to meet natural enemy be the warning, sound of call for help etc. that send in advance, be in mute state under normal circumstances, once ultrasonic sensing to there being bird flew near, will give a warning sound, drives birds and perch on shaft tower, reduce the possibility that birds are nested, prevent birds to nest in deathtrap.This device need have a power failure installation, and serves remarkable effect at the application initial stage to preventing birds to nest at shaft tower dangerous position, but after application a period of time, birds get used to eagle model and the cry of bird-scaring unit, and the dangerous position started again on electric pole is nested.Effectively can not frighten for a long time and expel birds, for residential neighborhood, easily cause noise pollution.
3, bird-resistant: solve the difficult problem that birds are nested at shaft tower dangerous position, be placed on the cross-arm on high-voltage transmission line pole tower insulator limit, prevent birds from nesting on cross-arm and stop for a long time, steel wire generally adopts the steel wire of diameter 2 millimeters, adopt the rotating structure of middle screw, increase elasticity, birds are made to stop and to fly away, from the effect of installing rear defence bird, this device can effectively prevent larger birds suspension string cross-arm position stop have a rest, the erosion of energy withstand long term exposure field sleet frost dirt, has long-term effect on driving birds.The installation but this device need have a power failure, and bird-resistant is metallic conductor, bird thorn need form the thorn hat with specific density and area, because 10kV distribution line cross-arm, electric pole and cable space are less, do not meet safe distance relatively, if reduce the length of bird-resistant, drive bird function by what reduce bird-resistant.
4, anti-bird pest cross-arm: by special structural design, makes bird not possess the condition of building nest, anti-bird pest Be very effective.Owing to being the product of new research and development, not coming into operation on a large scale, be used for newly-built 10kV distribution line, as changed the circuit that puts into operation, then need a huge sum of money and need large area, have a power failure for a long time.
5, other anti-bird pest measures among the people: as in position hung plastic bottle, plastic sack, even bird carcass.This type of way need have a power failure installation, and hangs the measure such as plastic bottle, plastic sack, even bird carcass, can only play flush effect in a short time.
