The present invention is a kind of device of puncturing because of Voltage for Insulators on HV Lines that bird pest causes of preventing, improves the insulator tolerance of ultra-high-tension power transmission line, guarantees line security operation.This device is directly installed on circuit suspension insulator top, to stop that birds droppings, foreign matter fall.Because surface is hard, a large amount of birds droppings are just when falling to umbrella body, be beneficial to and splash and bounce-back is gone out, can not form bridge joint conductive path (this point is better than silicon rubber material), guarantee that insulator string can not be short-circuited and around field intensity do not distort, fundamentally avoid falling to causing ground connection electric discharge trip accident because there are a large amount of birds droppings, foreign matter in suspension insulator top.
Theoretical foundation national grid internal specification of the present invention (18 great anti-accident measures of electrical network ' revised edition ') chapter 6 the 6th joint article one is for the regulation that prevents bird pest flashover fault.
The present invention is firm light, and handling are simple, and scientific structure design is reasonable, has fundamentally avoided falling to causing insulator ground connection, electric discharge, trip accident because there are a large amount of birds droppings, foreign matter in suspension insulator top, guarantees the safe operation of electric power system.
Advantage is specific as follows:
1, adopted a kind of special polymer composite, within bird-proof cover overall weight is reduced to 2Kg, than the weight saving of traditional glass steel matter bird-proof cover 1/3, be more convenient to installation and removal;
2, cover body is insulating material, the safety while guaranteeing circuit operation; And there is good hydrophobicity, birds droppings and foreign matter and be difficult for remaining in surface, and there is good resistance to low temperature, ultra-violet resistance and thermal endurance, can be for a long time for-40 ℃～+ 100 ℃ environment, be difficult for agingly, reach useful life more than 10 years;
3, this device adopts Belt-type tools once compressing, has adopted two-piece type to embed design in structure, and it is circular-arc, smooth hard that surface is projection;
4, place's brushing fluid sealant and by bolted is agreed with in gap, easy for installation; Central hole location is provided with the stressed silicagel pad of buffering, sealing is tight, effectively stop the stress causing because of factors such as wind shake to extend, avoided cover body joint because of overtired generation damage and fracture, stoped cover body because of under the External Force Actings such as wind relative to the rotating of insulator string, rock, the big-movement such as upset, improved the coefficient of safety after installing additional;
5, according to the regulation of national grid internal specification (18 great anti-accident measures of electrical network ' revised edition ') chapter 6 the 6th joint article one, according to the difference of line voltage distribution grade, the bird-proof cover product of design size gradual change, protection circuit safe operation better.
