Description

Vibration-absorbing connectors for overhead wires

Technical field

The utility model relates to the field of electric equipment, in particular to a connecting part that can slow down the vibration of overhead wires.

Background technique

In the field of electric power, with the continuous expansion of the civil power grid, the layout density of overhead wires is increasing, and the distribution structure is becoming more and more complex. For overhead wires, they often encounter impacts such as wind or rain. Since the two ends of the current overhead wires are fixed on the wire rack, all impacts from external forces will be balanced by the pulling force of the wire itself, so the vibration amplitude of the wire is large. , It is easy to break, which will affect the entire power grid and cause large economic losses. Therefore, it is necessary to improve the connection method of overhead wires.

Utility model content

For the above problems, the purpose of this utility model is to provide a vibration-damping connector for overhead wires. The vibration amplitude of small overhead wires makes the overhead wires not easy to break.

The technical solution adopted by the utility model to solve the technical problem is: the overhead wire vibration-damping connector includes a weight, a frame, a transverse spring, and a longitudinal spring, and the weight passes through the transverse spring and the longitudinal spring respectively in the transverse and longitudinal directions. Direction is connected with the frame, the frame is also provided with a threaded connection hole for connecting the wire frame, and a fixed terminal for wiring, the weight is provided with a vibration terminal.

Preferably, the elastic coefficient of the transverse spring and the longitudinal spring is smaller than that of the wires connected by the overhead wire vibration-damping connector, so that the transverse springs and the longitudinal springs are first stretched before the wires are stretched.

Preferably, the weight of the weight is greater than the weight of the wires connected by the overhead wire vibration-damping connector, so that external impact forces such as wind and rain can be mostly converted into kinetic energy of the weight.

Preferably, there are two transverse springs, which are arranged on the left and right sides of the weight, and one longitudinal spring, which is arranged on the side of the weight facing away from the electric wires.

Preferably, the fixed terminal is a bolt head.

Preferably, the vibration lug is a bolt hole and equipped with a bolt.

The beneficial effect of the utility model is that: after the overhead wire vibration-damping connector is fixed on the wire frame through the threaded connection hole, the overhead wire is connected to the weight, and under the impact of external wind and rain, the wire will pass the impact force The weight is transferred to the horizontal spring and the longitudinal spring. On the one hand, the spring absorbs the impact fluctuation of the wire in two directions. On the other hand, the spring transfers the energy to the weight, so that the impact energy is converted into Kinetic energy, thereby greatly reducing the vibration amplitude of the overhead wires, so that the overhead wires are not easy to break.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

In the embodiment shown in Fig. 1, the vibration-damping connector for overhead wires includes a weight 1, a frame 5, a transverse spring 6, and a longitudinal spring 7. Connected with the frame 5 in the longitudinal direction, the frame 5 is also provided with a threaded connection hole 4 for connecting the wire rack, and a fixed terminal 2 for wiring, and the weight 1 is provided with a vibration wiring head 3.

As shown in Figure 1, the above-mentioned overhead wire vibration damping connector, the frame 5 is a semi-enclosed structure for the weight 1, and the left and right sides and the rear of the weight 1 are respectively provided with the transverse spring 6 and the longitudinal spring. The spring 7, under the action of external force, can vibrate back and forth, left and right in the semi-enclosed area of the frame 5, and the weight 1, the transverse spring 6, the longitudinal spring 7, and the frame 5 can be connected by welding.

In the above-mentioned overhead wire vibration-damping connector, the elastic coefficients of the transverse spring 6 and the longitudinal spring 7 are smaller than the elastic coefficients of the wires connected by the overhead wire vibration-damping connector, so that the wires are stretched before stretching. 6 and longitudinal spring 7 are stretched first.

In the above-mentioned overhead wire vibration-damping connector, the weight of the weight 1 is greater than the weight of the wires connected by the overhead wire vibration-damping connector, so that external impact forces such as wind and rain can be mostly converted into the weight 1 kinetic energy.

In the aforementioned vibration-damping connector for overhead wires, there are two transverse springs 6 arranged on the left and right sides of the weight 1 , and one longitudinal spring 7 is arranged on the side of the weight 1 facing away from the electric wires.

In the above-mentioned vibration-damping connector for overhead wires, the fixed lug 2 is a bolt head.

In the vibration-damping connecting piece for overhead wires mentioned above, the vibration lug 3 is a bolt hole and is equipped with a bolt.

After the above-mentioned overhead wire vibration-damping connector is fixed on the wire frame through the threaded connection hole 4, the overhead wire is connected to the weight 1, and under the impact of external wind and rain, the wire will transfer the impact force to the weight 1 through the weight 1. On the above-mentioned transverse spring 6 and longitudinal spring 7, on the one hand, the spring absorbs the impact fluctuation of the wire in two directions; on the other hand, the spring transfers the energy to the weight 1, so that the impact energy is converted into the kinetic energy of the weight 1 , thus greatly reducing the vibration amplitude of the overhead wires, so that the overhead wires are not easy to break.
