Description
所属技术领域Technical field
本实用新型涉及电力设备领域,尤其是一种可以减缓架空电线振动的连接部件。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.
背景技术Background technique
在电力领域,随着民用电网的不断扩大,架空电线的布置密度越来越大,且分布结构越来越复杂。而对于架空电线,常常会遇到风力或雨水等冲击,由于目前的架空电线两端固结在电线架上,因此,对于外力的冲击,全部将由电线本身的拉力来平衡,故电线振动幅度大,容易拉断,从而影响到整个电网,造成较大的经济损失,因此很有必要对架空电线的连接方式进行改进。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.

作为优选,所述横向弹簧和纵向弹簧的弹性系数小于由该架空电线减振连接件所连接的电线的弹性系数,使电线在发生拉伸之前,所述横向弹簧和纵向弹簧首先被拉伸。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.
作为优选,所述重块的重量大于由该架空电线减振连接件所连接的电线的重量,以使得风力、雨水等外部冲击力可以大部分转化为所述重块的动能。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.
作为优选,所述横向弹簧具有两个,设置于所述重块左右两侧,所述纵向弹簧具有一个,设置于所述重块背向电线侧。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.
