Abstract
The utility model discloses a power transmission line guano-proof protective plate, which comprises cross arms and line hanging angle steels of a power transmission line tower. A protective plate for shielding insulators is mounted on the line hanging angle steels and is flat-plate-shaped or groove-shaped, the size of the protective plate corresponds to that of each wire hanging angle steel, and the protective plate is mounted above each insulating string and fixed via connecting bolts. The power transmission line guano-proof protective plate can effectively stop guano dropping on the insulators to cause short circuit or flashover, further can effectively prevent foul, ice, snow and the like from being accumulated on the insulators, has functions of preventing foul flashover and ice flashover, and is a better comprehensive protection measure.
Description
Technical field
The utility model relates to a kind of protective equipment of transmission line, refers in particular to a kind of facility of avoiding birds ight soil to cause transmission line instantaneous short circuit or flashover.
Background technology
Transmission line running environment is positioned at the field, overhead line structures provide one well to perch and the hunting platform for birds, and because electric pole and iron tower are higher than general trees, thereby enlarged the visual field of large-scale poultry, birds enjoy a lot to perch in such place and nest.In recent years, the tall and big trees that can perch for bird, mountain forest are reducing, and therefore are located in the wilderness, more secluded overhead line structures more and more become the desirable habitat of birds, make the bird pest accident of transmission line that the trend of rising be arranged.The shaft tower of transmission line all is provided with insulator, for making the insulation of electric wire and shaft tower.Long cross-arm is set on the shaft tower of ultra-high-tension power transmission line, insulator string by the hanging wire angle steel be suspended on cross-arm below, the insulator string lower end is power transmission line fixedly.The birds droppings that bird drains is a conductive materials, the ight soil that inhabits the birds discharging of insulator string top is dripping several sections continuous fine strip shapes of formation in the process down, fall from the insulator edge that dangles, and perch at the bigger bird defecation when taking off of the bodily form of cat head, birds droppings forms the longest birds droppings passage that reaches 1.2 meters between live part and iron tower rod member, can insulate by short circuit like this, form discharge channel and cause flashover.If birds droppings runs up to a certain degree in the SI semi-insulation sub-surface, when running into external environment influence such as air humidity increase, insulator Electric Field Distribution is on every side seriously distorted, most of voltage is added on the front end and the air gap between the insulator high-pressure side of birds droppings passage, is easy to cause lead and tower body instantaneous short circuit like this.
At present, the bird pest precautionary measures have multiple mode in the transmission line, as: flush device be brush red lacquer in the head of mast, hang little red flag, windbell be installed, anti-bird wheel, plastics windmill etc. roll, this method is simple, can also work at the initial stage of installing, but after after a while, birds have just adapted to this device.Therefore this device can only be met an urgent need temporarily, can not use for a long time.Bird-resistant generally is to form with the multiply steel strand manufacturing, and an end is fixed on the iron tower top, the top of string or wire jumper string of dangling, and the other end scatters, the group's of formation thorn-like.This device is made simple, easy for installation, certain effect is arranged, but its shortcoming be bird-resistant diameter hour bird can nearby perch in the same old way, and diameter can influence the service work to transmission line when big, steel wire time one length can deform simultaneously, breaking falls, and threatens line security.Scarer is to utilize the induced electricity energy storage and send the device that property is at interval rung, can prevent effectively that bird from dwelling on shaft tower, shortcoming is that cost height, operating experience are few, and after on one section shaft tower scarer being installed, birds can be moved on the shaft tower that bird-proof device is not installed nearby, therefore this device needs installing on a large scale, and is costly.Dangling, to add the mode of blocking be to install the gamp cover additional on the string top of dangling of insulator on the string top, can avoid birds droppings to connect along insulator string is whole, keeps the insulator string cleaning surfaces, and effect is better.Shortcoming is that material is softer, and is yielding, and need change insulator when this device will be installed on the transmission line that has moved, therefore costly, causes a large amount of wastes.The insulating protection measure is that the live part on 35kV and the following low-voltage distribution wire line pole tower is adopted the insulation booth protection, and guaranteeing does not have nuditing wire on the shaft tower, prevents that Bird's Nest or bird from causing ground connection or alternate flashover.Fruit is better to low-voltage distributing line for this method, but is not suitable for high-tension line.Perch abductive approach and be meant control or influence the position that bird perches and nests on shaft tower, some little bamboo basket are installed in the appropriate location of shaft tower are initiatively provided a nest, but effect is difficult to control to bird.Although the measure of anti-birds droppings has varied, all has some shortcomings or deficiency therefore at present.
The utility model content
The utility model technical issues that need to address provide a kind of anti-birds droppings backplate that can effectively protect the birds droppings on the transmission line.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Transmission line is prevented the birds droppings backplate, comprises the cross-arm and the hanging wire angle steel of electric power line pole tower, and the backplate of the insulator of screening is installed on the hanging wire angle steel.
Further improvement of the utility model is: backplate is fixedly installed on the hanging wire angle steel of each insulator string top with connecting bolt, and the size of backplate is corresponding with hanging wire angle steel size.
Further improvement of the utility model is: backplate is for adopting that sheet metal is made into and process antiseptic tabular of hot galvanizing or groove shape.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is at the anti-birds droppings backplate of shaft tower cross-arm hanging wire point place installing, the line short or the flashover that effectively stop birds droppings to be trickled down on insulator, to cause, and short circuit or the flashover effect of using the rear defence birds droppings to cause are remarkable.And can prevent effectively also behind the installing backplate that filth, ice and snow equivalance from falling on the insulator, can play the effect of anti-pollution flashover, anti-icing sudden strain of a muscle, be integrated protection measure preferably.Be a kind of economy, safety, the easily transmission line insulating protection measure of enforcement.Its service time for a long time, not yielding, expense is low, do not need to change existing facility, be convenient to install.Backplate of the present utility model can adopt sheet metal to make, and is easy to draw materials, and is easy to processing, and is cheap, and easy operating is installed simply; After adopting hot galvanizing to handle, antiseptic effect is better, and can be equal to the life-span of transmission tower useful life.The utility model utilizes original bolt connection on the iron tower, does not change the shaft tower original structure, does not influence structure function and transmission of electricity safety, does not need to increase separately material, firmly can not break away from.Be not only applicable to newly-built circuit, on the circuit that has moved, can conveniently implement yet.
