Invention content
The present invention is intended to provide a kind of anti-structure crossed lead and fallen off, connected lead using hauling rope and strain insulator insulate
Son reaches short circuit caused by preventing lead from loosening in the case where suspension insulator falls off with the metal bolt for crossing lead and trips
Purpose.
To achieve the above object, it specifically adopts the following technical scheme that：
It is a kind of it is anti-cross the structure that falls off of lead, including grounding switch 5, cross lead 1, fixed frame 4 and be installed on fixed frame
Strain insulator 2 on frame 4 and suspension insulator 3, it is described cross lead 1 respectively with 3 phase of strain insulator 2 and suspension insulator
Even, strain insulator 2 with and the crossing between lead 1 equipped with the hauling rope 6 that prevented lead 1 from loosening of being connected of suspension insulator 3.It is described
It crosses lead 1 to be also in series with grounding switch 5, can control whether grounding switch 5 is grounded by electronic box, with reply power supply, maintenance
Etc. situations.
Suspension insulator with cross lead usually using parallel hanging plate and screw connection, in rigging up and debugging or long-time service
In the process, due to the influence of climatic environment, such as in windy area, crossing the long-term vibrations of lead leads to the screw worked itself loose of parallel hanging plate
It is de-, if crossing lead loses traction, it will cause phase fault, gently then cause to trip, the heavy then station equipment that may cause to boost is damaged
And cause a series of serious consequence.And in the stressful times for robbing generated energy, it is found that the above situation is stopped to thoroughly handle needs
Unit is transported, the loss of up to ten million degree electricity is caused, does not also include the expense being switched on again.
Present invention employs a kind of simple hitch structure, lead 1 will be crossed and be connected and fixed with strain insulator 2, prevent by
The generation of short circuit phenomenon caused by crossing lead 1 and falling off.
The present invention further scheme be：When suspension insulator 3 is loosened with mistake lead 1, the mistake being connected with hauling rope 6 is drawn
The position of line 1 in space remains unchanged.
In said program, hauling rope 6 connected lead 1 and strain insulator 2 so that suspension insulator 3 with cross lead 1 it
Between parallel hanging plate thread off when kept the spatial position of lead 1 constant, ensure power transmission line between clearance, prevent accident from sending out
It is raw.
The present invention further scheme be：The structure includes the first strain insulator 21 and the second strain insulator 22,
The end of suspension insulator 3 is connected with lead 1 excessively and is biased to the direction setting of the second strain insulator 22；The structure is equipped with extremely
A few hauling rope 6, one end of hauling rope 6 with and the mistake leads 1 of 3 joining distal ends of suspension insulator be connected, the other end and first
Electrification side and/or not charged side on strain insulator 21 are mutually fixedly connected.
In said program, hauling rope 6 is connected lead 1 is crossed with the electrification side of the first strain insulator 21, in condition of power supply
Under, the current potential at 6 both ends of hauling rope is identical, can play good insulation draw.
The present invention further scheme be：The lead 1 of crossing is made of at least two conducting wires, and interval is equipped between the conducting wire
Stick 11, the hauling rope 6 are fixed on the conductor spacer 11 of 3 end of suspension insulator.
In said program, hauling rope 6 is connected with the conductor spacer crossed on lead 1 rather than is connected directly with lead is crossed, and prevents
Cross the creepage phenomenon that may occur between lead 1 and fixed frame 4, and it is convenient to carry out in rope threading operations.
The present invention further scheme be：The structure be equipped with two hauling ropes 6, respectively with the first strain insulator 21
Electrification side is connected with not charged side.
In said program, be equipped with two hauling ropes 6, respectively with the electrification side of distance the first strain insulator 21 farther out and
Not charged side be connected, the angle for drawing lead is constant, can play the role of it is optimal to fixation loosened lead 1.
The present invention further scheme be：The hauling rope 6 includes at least two flexible cables, and the flexible cable has moisture-proof
Insulation function.
In said program, under the conditions of power failure, since the first strain insulator 21 is grounded with one end that lead 1 is connected is crossed,
And the lead 1 of crossing being connected with suspension insulator 3 charges, therefore potential difference is produced between hauling rope 6, and since hauling rope 6 uses
Insulation and moisture material, it can be ensured that can also keep traction effect in this case.
In said program, if using a flexible cable, flexible cable both ends can not be bound, form annular, operation difficulty increases
Greatly, it and can not play the role of consolidating lead 1, therefore select two or more flexible cables, one is used to draw lead, separately
A piece cooperation traction flexible cable.
The present invention also provides a kind of hauling rope, including insulation wire rope core 61, at least one layer is surrounded by outside the insulation wire rope core 61
Damp-proof layer 62.
Due to the presence of creepage phenomenon, between crossing lead 1 with charged metal in precipitation wet environment electric arc occurs for insulating cord,
So that the insulation of hauling rope 6 reduces and turns on electric current, hauling rope 6 has been burnt, and the hauling rope 6 after burning can not play the work of drawing
With, therefore damp-proof treatment is carried out to it, increase damp-proof layer 62 outside the insulation wire rope core 61 of hauling rope 6.
The further scheme of above-mentioned hauling rope is：The damp-proof layer 62 includes internal layer fluorine silicone rubber 621 and outer layer fluorine silicon rubber
Glue 622, the cladding insulation wire rope core 61 of internal layer fluorine silicone rubber 621, outer layer fluorine silicone rubber 622 coat internal layer fluorine silicone rubber 621.
The further scheme of above-mentioned hauling rope is：The radius of the insulation wire rope core 61 and the thickness ratio of damp-proof layer 62 are 5:
2, the thickness of internal layer fluorine silicone rubber 621 is 1 with the thickness ratio of outer layer fluorine silicone rubber 622:3.
In said program, using internal layer fluorine silicone rubber 621 and the double-deck moisture-proof construction of outer layer fluorine silicone rubber 622, internal layer can be with
It is combined with insulation wire rope core well and prevents moisture from immersing, and the hole that when outer layer is then molded internal layer surface leaves is filled up,
Using above-mentioned radius and thickness than insulation wire rope core 61 and damp-proof layer 62 so that hauling rope 6 also has splendid hold on rainy day
Phase voltage ability is carried on a shoulder pole, will not be burnt because of insulation breakdown, which leads to pull effect, disappears.
The present invention also provides a kind of preparation methods of hauling rope, include the following steps：
(1) it takes insulation wire rope core to immerse in fluorine silicone rubber coating, is kept for 8~15 minutes；
(2) the insulation wire rope core taking-up after being impregnated in step (1) is dried 1~2 hour, obtains being coated with internal layer fluorine silicone rubber
Hauling rope；
(3) hauling rope after being dried in step (2) is again dipped into fluorine silicone rubber coating, is kept for 2~5 minutes；
(4) hauling rope after being impregnated in step (3) is dried 1~2 hour, obtains being coated with internal layer fluorine silicone rubber and outer layer
The hauling rope of fluorine silicone rubber.
Manufactured hauling rope is measured, is measured with 2500V megameters, insulation resistance is more than 10G Ω；It is resistance to carry out power frequency
Pressure experiment, under the conditions of 100KV/0.5m, continues 5 minutes, as a result meets the requirement of GB/T 13035-2008；Be broken strong
Degree measures, rope diameter 6mm, and fracture strength is more than 4KN, meets GB/T13035-2008 requirements.
