Description

A kind of middle phase conductor wind deflection preventive for single loop electric power line pole tower
Technical field
The present invention relates to a kind of middle phase conductor wind deflection preventive for single loop electric power line pole tower, belong to power circuit Service technique field.
Background technology
Trip accident is to endanger one of subject matter of line security operation.According to the system of State Grid Corporation of China in 2015 Meter, causes the main cause of line tripping to be followed successively by:Thunderbolt(617 times, account for 40.6%), external force destruction(330 times, account for 21.7%)、 Ice trouble(201 times, account for 13.2%), bird pest(170 times, account for 11.2%)And windburn(152 times, account for 10%).Cause the main of failure stoppage in transit Reason is followed successively by:External force is destroyed(174, account for 31.6%), ice trouble(156 times, account for 28.4%), windburn(104 times, account for 18.9%)Thunderbolt (69 times, account for 12.5%)And bird pest(19, account for 3.5%).
Statistical result more than can be seen that windage yaw tripping operation and endanger larger to circuit.Because windage yaw tripping operation causes circuit Failure stoppage in transit probability is higher(Account for more than 90%), the harm for sending out circuit for the higher circuit of importance and power plant is particularly bright It is aobvious.In addition some regional strong wind natural calamities take place frequently, and regional wind-deviation work is particularly important herein.
The content of the invention
Windage yaw thoroughly can be solved the problems, such as using " V " type string for newly-built circuit.And in the circuit one of operation As insulator chain will still be put to tower body in the presence of strong wind by the way of weight-adding hammer and double string " eight words " arrangement, but so It is dynamic.The area taken place frequently for strong wind natural calamity, once windage yaw accident will still be occurred by instantaneous extreme wind occur.
Middle phase pinning assembly is exactly to utilize one group of insulation and telescopic device, the main material on the inside of single loop steel tower lower bent lever Connected between crosspoint and wire pendency series board.So pining down wire, it is not occurred again in the presence of strong wind larger Deflection, thoroughly solves the problems, such as middle phase conductor windage yaw.
According to the above analysis, if there is a kind of pinning assembly of insulation, the main material crosspoint on the inside of single loop steel tower lower bent lever It is connected between wire pendency series board, it is possible to prevent wire from occurring larger deflection, steel tower is not being changed on a large scale The windage yaw of phase conductor in thoroughly being solved the problems, such as in the case of making.
The technical problems to be solved by the invention are that the defect for overcoming prior art is used for single loop power transmission line there is provided one kind The middle phase conductor wind deflection preventive of line pole tower.
In order to solve the above technical problems, a kind of middle phase conductor for single loop electric power line pole tower of present invention offer is windproof Deflection device.The present invention is one group of seal that is scalable and having some strength, it is necessary to connect bent under single loop steel tower On the inside of arm between main material crosspoint and wire pendency series board.When wire is by horizontal loading, wire suspension string deflects, Pinning assembly can extend therewith.When wire suspension string deflects into certain angle, pinning assembly stops extending and pining down leading Line suspension string makes it not continue to deflection, so as to play a part of wind-deviation.
The present invention is adopted the following technical scheme that:A kind of middle phase conductor wind-deviation for single loop electric power line pole tower is filled Put, including single loop electric power line pole tower, the single loop electric power line pole tower include being arranged at top on crank arm, be arranged at The lower bent lever of bottom, it is characterised in that cranked arm on described be provided between the lower bent lever middle phase conductor suspension insulator, Middle phase pinning assembly, the top of the middle phase conductor suspension insulator with it is described on the middle part cranked arm be connected, the middle phase The bottom of wire suspension insulator is connected with the top of the middle phase pinning assembly, the bottom of the middle phase pinning assembly with It is connected on the inside of the lower bent lever.
As a kind of preferred embodiment, the front and rear sides of the inner side of lower bent lever are respectively arranged with main material crosspoint, main material Hanging hole is provided with crosspoint, the bottom of middle phase pinning assembly is connected by hanging hole with main material crosspoint.
As a kind of preferred embodiment, middle phase pinning assembly includes upper junction plate, connecting rod, lower connecting plate, elasticity and stretched Compression apparatus, connecting rod nesting is arranged at the inner side of upper junction plate and lower connecting plate, and the bottom of upper junction plate is by connecting rod with The top of connecting plate is connected, and the bottom of lower connecting plate is connected with the top of elastic telescopic device, the bottom of elastic telescopic device End is connected with the front and rear sides of the inner side of lower bent lever, the top of upper junction plate and the bottom phase of middle phase conductor suspension insulator Connection.
As a kind of preferred embodiment, some hinge holes are offered on upper junction plate, connecting rod and lower connecting plate, on It is hinged between connecting plate, connecting rod and lower connecting plate by hinge hole.
