Abstract

The utility model provides a vibration-reducing connecting part of an overhead electric wire. The vibration-reducing connecting part comprises a heavy block, a frame, a horizontal spring and a longitudinal spring, wherein the heavy block is connected with the frame respectively in horizontal direction and longitudinal direction by the horizontal spring and the longitudinal spring, the frame is provided with a thread connecting hole for connecting the electric wire frame and a fixed connector lug for wiring, and the heavy block is provided with a vibration connector lug. The connecting part not only can connect the overhead electric wire to the electric wire frame but also can buffer external impact force from wind and rain and the like and can reduce the amplitude of vibration, so that the overhead electric wire is not easy to break off.

Description

Trolley wire vibration damping connector
Affiliated technical field
The utility model relates to field of electrical equipment, especially a kind of link that can slow down the trolley wire vibration.
Background technology
At power domain, along with the continuous expansion of domestic power grid, the layout density of trolley wire is increasing, and distributed architecture becomes increasingly complex.And for trolley wire; usually can run into impacts such as wind-force or rainwater; because present trolley wire two ends are cemented on the Electric wire support, therefore, for the impact of external force; all will come balance by the pulling force of electric wire itself; so the conductor vibration amplitude is big, breaks easily, thereby has influence on whole electrical network; cause bigger economic loss, therefore necessary connected mode to trolley wire is improved.
The utility model content
For above-mentioned problem, the purpose of this utility model is to provide a kind of trolley wire vibration damping connector, this connector not only can be connected to Electric wire support with trolley wire, and can cushion external impact force such as wind-force, rainwater effectively, reduce the Oscillation Amplitude of trolley wire, make not frangibility of trolley wire.
The technical scheme that its technical problem that solves the utility model adopts is: this trolley wire vibration damping connector comprises pouring weight, framework, crossed strip, longitudinal spring, described pouring weight is connected with described framework respectively in the horizontal and vertical directions by described crossed strip, longitudinal spring, also be provided with the threaded connection hole that is used to connect Electric wire support on the described framework, and the link head that is used for wiring, described pouring weight is provided with the vibration connector lug.
As preferably, the coefficient of elasticity of described crossed strip and longitudinal spring makes electric wire before stretching less than the coefficient of elasticity by this trolley wire vibration damping connector institute wire connecting, and described crossed strip and longitudinal spring at first are stretched.
As preferably, the weight of described pouring weight is greater than the weight by this trolley wire vibration damping connector institute wire connecting, so that external impact force such as wind-force, rainwater can major part be converted into the kinetic energy of described pouring weight.
As preferably, described crossed strip has two, is arranged at the described pouring weight left and right sides, and described longitudinal spring has one, is arranged at described pouring weight electric wire side dorsad.
As preferably, described link head is a bolt head.
As preferably, described vibration connector lug is a bolt hole, and is furnished with a bolt.
The beneficial effects of the utility model are: after this trolley wire vibration damping connector is fixed on the Electric wire support by threaded connection hole, trolley wire is connected on the pouring weight, then externally under the impact of wind-force, rainwater, electric wire is transferred to impulsive force on described crossed strip and the longitudinal spring by pouring weight, absorb the impact fluctuation of electric wire on both direction by spring on the one hand, on the other hand, spring transfers the energy on the pouring weight again, make impact energy change into the kinetic energy of pouring weight, reduced the Oscillation Amplitude of trolley wire thus greatly, made not frangibility of trolley wire.
Description of drawings
Fig. 1 is the structure chart of this trolley wire vibration damping connector.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
In the embodiment shown in fig. 1, this trolley wire vibration damping connector comprises pouring weight 1, framework 5, crossed strip 6, longitudinal spring 7, described pouring weight 1 is connected with described framework 5 respectively in the horizontal and vertical directions by described crossed strip 6, longitudinal spring 7, also be provided with the threaded connection hole 4 that is used to connect Electric wire support on the described framework 5, and the link head 2 that is used for wiring, described pouring weight 1 is provided with vibration connector lug 3.
Above-mentioned trolley wire vibration damping connector, as shown in Figure 1, described framework 5 is the semi-surrounding structure for described pouring weight 1, described pouring weight 1 left and right sides and rear are respectively equipped with described crossed strip 6 and longitudinal spring 7, under external force, can in the semi-surrounding zone of described framework 5, carry out all around vibrating, can adopt welding manner to link between described pouring weight 1, crossed strip 6, longitudinal spring 7, the framework 5.
Above-mentioned trolley wire vibration damping connector, the coefficient of elasticity of described crossed strip 6 and longitudinal spring 7 is less than the coefficient of elasticity by this trolley wire vibration damping connector institute wire connecting, make electric wire before stretching, described crossed strip 6 and longitudinal spring 7 at first are stretched.
Above-mentioned trolley wire vibration damping connector, the weight of described pouring weight 1 be greater than the weight by this trolley wire vibration damping connector institute wire connecting, so that external impact force such as wind-force, rainwater can major part be converted into the kinetic energy of described pouring weight 1.
Above-mentioned trolley wire vibration damping connector, described crossed strip 6 has two, is arranged at described pouring weight 1 left and right sides, and described longitudinal spring 7 has one, is arranged at described pouring weight 1 electric wire side dorsad.
Above-mentioned trolley wire vibration damping connector, described link head 2 is a bolt head.
Above-mentioned trolley wire vibration damping connector, described vibration connector lug 3 is a bolt hole, and is furnished with a bolt.
After above-mentioned trolley wire vibration damping connector is fixed on the Electric wire support by threaded connection hole 4, trolley wire is connected on the pouring weight 1, then externally under the impact of wind-force, rainwater, electric wire is transferred to impulsive force on described crossed strip 6 and the longitudinal spring 7 by pouring weight 1, absorb the impact fluctuation of electric wire on both direction by spring on the one hand, on the other hand, spring transfers the energy to again on the pouring weight 1, make impact energy change into the kinetic energy of pouring weight 1, reduced the Oscillation Amplitude of trolley wire thus greatly, made not frangibility of trolley wire.
