Description
Technical field
Electric pole is the utility model is related to, is specially a kind of straight line pole cap for flock of birds interference feeder line fault.
Background technology
Phase fault repeatedly occurs 35kV for focal line, Jiao's 35kV new line forever in recent years, and 35kV forever concentrate by focal line trouble point
In 16#-40# strain sections, length 3.267km；Jiao's 35kV new line trouble point concentrates on 85#-120# strain sections, length 4.812km.
Two lines line conductor uses LGJ-120/20 shaped steel core aluminum stranded wires, and completely using suspension type composite insulator, faulty section is without ground
Line, main force's rod-type are ZS1 series of straight lines bars, and conducting wire is in triangle arrangement.
The transmission line of electricity specific responsibility of O＆M maintenance portion, through grinding, circuit master sets and Yongchang County Utilities Electric Co. related personnel repeatedly gos deep into
Field investigation, analyzes fault in-situ photo, preliminary to assert that failure cause is due to that pigeon passes through circuit and causes middle phase-side phase in groups
Short circuit.
The reason for drawing conclusions is analyzed：The landform of multiple section of two lines road failure, landforms are similar, are respectively positioned on open ground
Band, landforms are arable land, plant barley or wheat, surrounding have sporadicly been located village, understand through scene, the location crops harvesting season
Save as annual 9, October, using mechanical harvesting.All rise winged photo with reference to live dove and the line fault multiple phase concentrate on 9,
The situation of 10 two months, looks for food the reason for this is that the wheat being scattered after mechanical harvesting in farmland, barley attract pigeon nearby, and surrounding is opened
Wealthy environment easily forms pigeon and takes off in groups, and when dove group passes through 35kV circuits with the larger formation of density, pigeon spacing reaches drawing
Cause phase fault during arc critical value.After October, as the grain reduction being scattered in arable land and peasant household start to plow, dove group turns
And other places of looking for food are found, therefore failure is also greatly decreased after October.
Therefore a kind of method for solving flock of birds interference generation phase fault is urgently studied.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, overcome the shortage of prior art, disclose a kind of to be used for flock of birds and disturb
The straight line pole cap of feeder line fault, phase hanging wire mode in the strain section straight line pole of two lines road Frequent Accidents has been changed to
Machine composite cross-arm insulator supports hanging wire, and middle phase conductor will be greater than 4m with side phase conductor vertical range after secondary transformation.Specifically arrange
Apply to process the top cover anchor ear suitable for ZS1, ZS1+3, ZS1+6, ZS2, ZS2+3 bar, double string organic composite cross-arm insulation are installed
Son, the top cover anchor ear of ZS1 series, which often covers, nearly weighs 47kg, and the top cover anchor ear of ZS2 series, which often covers, nearly weighs 60kg.
To achieve the above object, the present invention uses following technical scheme：
A kind of straight line pole cap for flock of birds interference feeder line fault, including concrete bar, the concrete bar top are equipped with top
Cap, the top cap upper end are equipped with composite cross-arm insulator, and the concrete bar top is arranged with the first composite suspension type insulators and
Two composite suspension type insulators, first composite suspension type insulators are connected by conducting wire with top cap, and the second compound suspension type is exhausted
Edge is connected by conducting wire with concrete bar top.
Preferably, the composite cross-arm insulator top and the first composite suspension type insulators bottom are at a distance of 400cm.
Preferably in first composite suspension type insulators and the second composite suspension type insulators bottom are in same level
Face.
Preferably, first composite suspension type insulators are connected with the second composite suspension type insulators by lower cross-arm.
Preferably, the top cap is fixed on concrete bar top by top cap anchor ear, and the top cap anchor ear is by two semicircle anchor ears
Type combination ironware is formed, and the top cap anchor ear internal diameter is adapted to concrete bar outside diameter.
Preferably, the top cap anchor ear weight is 45-62kg.
Preferably, the middle phase conductor is more than 4m with side phase conductor vertical range.
Beneficial effects of the present invention are：The straight line pole top for being used for flock of birds interference feeder line fault of the utility model design
Cap, adapts to each field location for occurring flock of birds harm on power circuit, can solve the phase caused by dove group's ruler road
Between short circuit, less investment, solve method it is simple and easy to operate, difficulty of construction is little.

Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
A kind of straight line pole cap for flock of birds interference feeder line fault as shown in Figure 1, Figure 3, including concrete bar 1, concrete
1 top of bar is equipped with top cap 2, and 2 upper end of top cap is equipped with composite cross-arm insulator 3, and it is exhausted that 1 top of concrete bar is arranged with the first compound suspension type
4 and second composite suspension type insulators 5 of edge, the first composite suspension type insulators 1 are connected by side phase conductor 6 with top cap 2, and second is multiple
Suspension insulator 5 is closed by side phase conductor 6 with 1 top of concrete bar to be connected.3 top of composite cross-arm insulator and the first compound suspension type are exhausted
4 bottom of edge is at a distance of 400cm.First composite suspension type insulators 4 and 5 bottom of the second composite suspension type insulators are in same level
Face.First composite suspension type insulators 4 are connected with the second composite suspension type insulators 5 by lower cross-arm 8.Top cap 2 passes through top cap anchor ear
201 are fixed on 1 top of concrete bar, and top cap anchor ear 201 combines ironware 202 by two semicircle anchor ear types and forms, 201 internal diameter of top cap anchor ear
It is adapted to 1 outside diameter of concrete bar.201 weight of top cap anchor ear is 45-62kg.Middle phase conductor 7 is more than 4m with 6 vertical range of side phase conductor.
As shown in Fig. 2, be existing straight line pole arrangement at present, when dove group passes through 35kV circuits with the larger formation of density, dove
Sub- spacing causes phase fault when reaching arcing critical value.
Compared with current straight line pole top, the composite cross-arm insulator 3 of 1 upper end of concrete bar is by parallel to concrete bar 1, being arranged on instead
1 top of concrete bar, 1 top of concrete bar are equipped with top cap anchor ear 201, the double string organic composite cross arm insulators 3 of 1 top of concrete bar installation.Change
It is original it is widely used " on " mode of word row conductor mounting arrangement so that the middle phase conductor 7 and side phase conductor 6 of homonymy arrangement
Between distance substantially increase, static ranging is avoided because strong wind is waved, flock of birds inhabites phenomena such as suppressing of taking off up to 400cm
Caused phase spacing deficiency afterwards, has prevented the situation that conventional phase fault takes place frequently, improve circuit security and can
By property.Practical application positive effect, improvement cost is cheap, has and is widely popularized value
The straight line pole cap for being used for flock of birds interference feeder line fault of the utility model design, adapts on power circuit
There is each field location of flock of birds harm, the phase fault caused by dove group's ruler road, less investment, solution party can be solved
Method is simple and easy to operate, and difficulty of construction is little.
Above-described embodiment, simply presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalence changes that content described in invention claim is done, should all be included within scope of the invention as claimed.
