Description
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.
