Description
Technical field
The utility model belongs to transmission line equipment technical field, and in particular to a kind of wind deflection preventive of insulator chain.
Background technique
Under wind load excitation, conducting wire, the insulator chain of transmission line of electricity will generate wind-induced vibration, significantly wind swing
Reduce the air gap between cable and shaft tower, trees etc., serious conditions can generate electric discharge phenomena, run to transmission line safety
Cause greater risk；The reciprocating motion of another aspect conducting wire, insulator is easy to cause insulator chain, fitting the fatigue of material broken
It is bad.Because tripping caused by windage yaw electric discharge, is that wind load is larger, windage yaw causes the duration that minimum air void is exceeded,
The usually much larger than reclosing operation time limit, so that the gap of conducting wire and shaft tower is still less than between air in reclosing operation
Gap requirement；Meanwhile when reclosing operation, occur switching overvoltage in transmission line of electricity, is much larger than power-frequency sparkover voltage, causes to influence
Even more serious secondary discharge.Many scholars take finite element method to study windage yaw, but do not obtain effective solution
Certainly method lacks effective method in actual production and solves windage yaw.Therefore, reduce windage yaw probability of happening from practical, to electric power
The safe operation of system and the wind-deviation design of new route have important practical significance.
Utility model content
The purpose of this utility model is the wind swing to solve the problems, such as the insulator chain in transmission line of electricity, provides one kind
The wind deflection preventive of insulator chain.
To solve the above problems, the technical scheme adopted by the utility model is a kind of wind deflection preventive of insulator chain,
Including cross-arm, the insulator chain being connected with cross-arm；Wherein: it further include high-performance limiting buffer device, cross-arm connection pedestal, absolutely
Edge substring connects pedestal；The cross-arm connection pedestal is located at the bottom of cross-arm, and the insulator chain connection pedestal is located at absolutely
On the fitting of edge substring, it is hinged that one end of the high-performance limiting buffer device connect pedestal with cross-arm, the other end and insulator chain
It is hinged to connect pedestal.
Preferably, the angle of the high-performance limiting buffer device and cross-arm is between 15 ° to 45 °.
Preferably, high-performance limiting buffer device can be set to the two sides of insulator chain.
Compared with prior art, the utility model has the advantage that
First, the utility model can reduce the amplitude and frequency of insulator chain by high-performance limiting buffer device, reduce
The abrasion of fitting, and make windage yaw angle in safe range；When wind-force is lesser, the angle of wind deflection of insulator chain is effectively buffered
Degree reduces the angle and frequency of its vibration, reduces the fatigue rupture of insulator chain and fitting material；It, will when wind-force is larger
Windage yaw angle is limited in safe range, substantially reduces the probability of happening of windage yaw discharge, reduces the generation of trip accident.
Second, make insulator chain not only can be along the windage yaw in cross-arm direction by the way of hinged, and can produce one
The fixed windage yaw perpendicular to cross-arm direction, application range is wider, safer.
Third keeps transmission line safety operation in high wind, and improves the service life of insulator chain and fitting, reduces
Line upkeep frequency.
4th, present apparatus structure is simple, is easy to install additional, easy to maintain.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Specific embodiment
As shown in Figure 1, a kind of wind deflection preventive of insulator chain described in the present embodiment, including cross-arm 1, it is connected with cross-arm
Insulator chain 5；It further includes high-performance limiting buffer device 2, cross-arm connection pedestal 3, insulator chain connection pedestal 4；Described
Cross-arm connection pedestal 3 is located at the bottom of cross-arm 1, and the insulator chain connection pedestal 4 is located on the fitting 6 of insulator chain 5, institute
The one end for stating high-performance limiting buffer device 2 connect pedestal 3 with cross-arm hingedly, and it is hinged that the other end connect pedestal 4 with insulator chain.
To reduce the mechanical property requirements of buffer, the cost of the present apparatus, the high-performance limiting buffer are reduced
The angle of device 2 and cross-arm 1 is between 15 ° to 45 °.
The biggish area of wind-force in part, the two sides of insulator chain 5 are all provided with high-performance limiting buffer device 2.
The utility model prevents the device from causing under route integral insulation performance to improve the insulation performance of the device
Drop carries out insulation spray painting at cross-arm connection pedestal 3, insulator chain connection pedestal 4.
When insulator chain is in a vertical state, buffer is in the state that do not stress, and length is maximum；Wind occurs for insulator chain
When inclined, the power that windage yaw generates is transferred to high-performance limiting buffer device by the top fitting of insulator chain, by compression high-performance limit
Digit buffer, high-performance limiting buffer device generates reversed power to fitting at this time, and absorbs the part kinetic energy of insulator chain, makes
The shaking of insulator chain reduces；It is total in the thrust of high-performance limiting buffer device and the gravity of insulator chain when windage yaw reaches maximum
Under same-action, windage yaw angle is in safe range.
