Abstract
The utility model relates to a bird-trouble flashover preventing device of a transmission line, wherein the lower end of a suspension insulator is a grading ring, on which a high pressure suspension clamp is hung; a transmission conductor is supported on the high pressure suspension clamp, a composite insulating big umbrella is fixed on the suspension insulator above the grading ring, a clamp insulation sheath is fixed on the high pressure suspension clamp, and a conductor insulation sheath is fixed on the transmission conductor near to the high pressure suspension clamp. The bird-trouble flashover preventing device of the transmission line disclosed by the utility model is simple in structure and capable of effectively preventing from the flashover caused by bird droppings.
Description
Technical field
The utility model belongs to transmission line anti-bird pest technology, particularly a kind of device of anti-bird pest flashover
Background technology
Along with the continuous improvement of biological environment, birds quantity increases, and frequent activity makes power transmission and transformation line happen occasionally because of the tripping operation power outage that bird pest causes.Electric power line pole tower is the normal habitats of selecting of birds, and birds nest on shaft tower, lay eggs, hatch.Bird's Nest on shaft tower is blown to four winds and drops on live wire or insulator, can cause short circuit grounding fault (flashover).Birds can void excreta every day, and concentrated phenomenon of sending ight soil when morning is arranged.The bird that stands on tower head aloft drains, particularly the large birds discharge just rare, cause single-phase earthing when insulator trickles, perhaps birds droppings blows to the wind electrified body and causes the air gap short circuit to puncture, and causes the birds droppings flashover fault.According to incompletely statistics, the Bird-caused Fault that causes due to birds droppings accounts for more than 95%.
The anti-bird pest measure of existing use mainly contains bird scarer, bird-scaring unit, anti-bird plate washer, bird-resistant etc., still can play a role at the initial stage of installing additional, and along with the enhancing of birds adaptive capacity, the time is accustomed to once long, and is ineffective.This makes the preventing and controlling of bird pest flashover fault fail all the time the progress of making a breakthrough property, and along with the bird pest flashover fault of progressively becoming better of biological environment presents ever-increasing trend.
Summary of the invention:
In order to overcome the shortcoming of prior art, the utility model provides a kind of Against Bird Flashover of Transmission Line device, and it is simple in structure, can effectively prevent the flashover that causes due to bird pest.
The technical scheme in the invention for solving the technical problem is: the lower end of suspension insulator is grading ring, hangs the high pressure suspension clamp, and the pop-up of high pressure suspension clamp has transmission pressure; Fixing compound inslation gamp on the suspension insulator of described grading ring top; Be fixed with the wire clamp insulating sleeve on described high pressure suspension clamp; Described near fixing cord insulating sleeve on the transmission pressure of high pressure suspension clamp.
The utility model installs the compound inslation gamp additional by the position above insulator equalizing ring, the insulation blocking grading ring; At suspension clamp and both sides transmission pressure, wire clamp insulating sleeve and wire insulating sheath are installed respectively, are formed the integral insulation in overhead transmission line tower head zone; The foreign matter that small bird is dropped when particularly draining birds droppings, is avoided forming local conductive channel, reaches the purpose that prevents the bird pest flashover fault.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
