Abstract

The utility model discloses an anti-bird insulated comprehensive protection device for a high-tension power transmission line. The device is characterized in that the two ends of a protection box are provided with buckle insulation sleeves. The device adopts the composite insulation scheme of the insulated comprehensive protective box and the buckle insulation sleeves and aims to increase the external flash leakage distance of an insulator and also increase the air insulation margin of a bare wire to a tower; therefore, the insulation of the aerial bare wire is strengthened, the flashover level is greatly improved, and the insulated protection requirement of a system can be met.

Description

The anti-bird pest insulation of ultra-high-tension power transmission line integrated protection device

Technical field

The utility model relates to and a kind ofly prevents that big migratory bird (stork class, crane class) from nesting or stopping perch defecation and cause flashover fault on 110KV, 220KV high-voltage transmission line towers, causes the integrated protection device of large-area power-cuts.

Technical background

Along with the electric power system user to the demand of capacity and the science and technology development of people's daily life aspect; power department is more and more higher to the requirement of transmission line security of operation; regional northeastward; especially area, Qiqihar has considerable 110; the 220KV overhead transmission line is positioned at the wetland nature reserve area; in large-scale migratory bird (stork class) defecate; high filthy; thunderstorm; under the humidity effect of high wind-force and saline-alkali wetland; discharged to shaft tower in gold utensil wire clamp position; the thing that repeats to trip often takes place; influence the security of operation of circuit, caused heavy losses for local economical production.According to the accident potential that these phenomenons occurred, how to solve the security of operation of overhead transmission line, increase the insulation distance of its gold utensil wire clamp and two ends lead-in wire and shaft tower, avoid the generation of circuit repeatability tripping operation accident, just become more and more crucial.

Traditional method is as installing various bird proof devices additional above the insulator of shaft tower, drainage to the middle-size and small-size birds ight soil below the 5KG has had certain obstruction, solve the bird pest problem under the general situation, but can not solve the outer problem of climbing that above large-scale migratory bird (stork class) defecate of 5KG causes; Have again and above composite insulator, install anti-bird skirt of silicon rubber or creeping-increasing skirt additional, solved the creepage distance on top, but the air flashover of following gold utensil and aerial bare line part still occurs; Also have lapped insulation band on gold utensil and aerial bare line, be mounted for big problem, large-area power-cuts is installed and can't be realized.

The utility model content

Technical problem to be solved in the utility model provides and a kind ofly can prevent that really large-scale migratory bird defecation from causing flashover fault to cause the bird damage prevention device of large-area power-cuts.By taking insulation measures to make the exposed gold utensil of circuit obtain insulating protection, and then the flashover passage of cutoff high discharge, reach the purpose of security protection.

For solving the problems of the technologies described above, the utility model provides the anti-bird pest insulation of a kind of ultra-high-tension power transmission line integrated protection device, it is characterized in that: establish the buckle insulating sleeve at the two ends of protection box.

The utility model integrated protection box of taking to insulate adds the compound inslation scheme of buckle insulating sleeve, purpose is to prolong the outer leakage distance of dodging of insulator, reaching increases the air insulation nargin of bare wire to shaft tower simultaneously, the insulation of aerial bare line is strengthened, the flashover level promotes greatly, can satisfy the insulating protection requirement of its system.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

With reference to accompanying drawing, ZLFN-series gold utensil wire clamp insulation integrated protection box 1 is to be raw material with high-performance poly alkene, cooperates anti-aging, uvioresistant, anti-electric trace additive, pass through mixing, extrude, mold pressing and crosslinking with radiation moulding.Insulation integrated protection box 1 is to opening structure, and purpose is at overhead transmission line the gold utensil wire clamp not to be needed dismounting, helps suit and coated.The edge of opening adopts U type sealing profile to clamp the design of insulative water-proof adhesive tape, and it is fastening to be aided with insulated bolt 5, has not only increased dielectric strength but also the fine water proof and dust proof problem that has solved interface.Three interfaces of insulation integrated protection box 1 with the insulated enclosure waterproof adhesive tapes respectively with the link plate and lead 4 adhering and sealings of insulation integrated protection box 1 inner gold utensil wire clamp, both effectively raised the insulation level of global design, stoped the intrusion of rainwater, dust and moisture again, and support fixation insulation integrated protection box 1, thereby solved friction problem between insulation integrated protection box 1 and gold utensil wire clamp and the lead 4.

According to the design feature of gold utensil wire clamp, goat's horn outlet position is adopted inclined design and is kept certain space, prevents internal friction.The outlet position of aerial condutor 4 prolongs 100mm, and overhead wire outlet position lapped insulation water-tight adhesive tape makes insulation integrated protection box 1 that a stability reliably be arranged.Guaranteed the free gap of gold utensil wire clamp, can make its inside not frayed again.Integral body both saw and coordinated, firmly, improved anti-withstand voltage properties again.Easy for installation, need not to dismantle the gold utensil wire clamp, need not large-area power-cuts and install, but live line working does not influence the normal operation of transmission of electricity.

Begin to adopt buckle insulating sleeve 2 to carry out supplementary insulation from the gold utensil wire clamp to stockbridge damper 3 positions, the insulation of aerial condutor 4 is strengthened, the flashover level promotes greatly, only need insulating sleeve is centered on bare wire by craft or instrument with sheath, and button box together, form complete insulation system, it need not be inserted in from an end, does not also need wrapped or heat shrink.Products characteristics: exempt from and contract, till the fastening, insulation fully, use convenience, craft, machinery all can, can accomplish continuous 30M, can realize the large span construction, be applied to the comprehensive insulating protection (foreign matter overlaps, icicle, antifog sudden strain of a muscle etc.) of aerial bare line.

Claims

1. the anti-bird pest insulation of a ultra-high-tension power transmission line integrated protection device is characterized in that: establish the buckle insulating sleeve at the two ends of protection box.
