Insulator with damping function

Abstract

The invention discloses an insulator with a damping function, which comprises a plurality of umbrella trays connected up and down, the lower ends of the umbrella trays are connected with wire clamps, at least one buffer is connected among the umbrella trays, each buffer comprises a cylinder, a piston is sleeved in each cylinder, and a reinforcing ring is arranged on a piston rod at the upper port of each cylinder. An elastic annular corrugated cover is arranged between the reinforcing ring and the upper end of each cylinder, at least four telescopic rods are evenly and symmetrically arranged around the reinforcing ring in a surrounding mode, the outer ends of the telescopic rods are fixedly connected to the inner side walls of the cylinders through transverse springs, and fixing rings are arranged on the inner side walls of the cylinders and located below the transverse springs and the outer ends of the telescopic rods. At least four vertical springs A are evenly and symmetrically arranged between the lower end faces of the fixing rings and the upper end faces of the pistons in a surrounding mode, and at least four vertical springs B are evenly and symmetrically arranged between the lower end faces of the pistons and the bottoms of the cylinders in a surrounding mode. Vibration energy in the horizontal direction and the vertical direction can be buffered at the same time when the power transmission conductor swings, and the damping effect is better.

Description

technical field [0001] The invention belongs to the technical field of insulators for power transmission, and relates to an insulator, in particular to an insulator with a shock absorbing function. Background technique [0002] During power transmission, the transmission wire is suspended on the transmission tower through insulators and clamps. Natural disasters such as storms and rains will cause the transmission wire to swing greatly, resulting in damage or even collapse of the transmission tower, causing huge losses to the State Grid. [0003] In order to prevent the transmission tower from being damaged due to the swaying of the transmission wire, there has been a Chinese invention patent "A Shock Absorbing Insulator for Transmission Wire" with the authorized announcement number CN102509592B, by adding elastic or magnetic fluid between the umbrella plates The buffer can overcome the alternating load of the transmission wire and effectively protect the transmission tower,...

[0002] During power transmission, the transmission wire is suspended on the transmission tower through insulators and clamps. Natural disasters such as storms and rains will cause the transmission wire to swing sharply, resulting in damage or even collapse of the transmission tower, causing huge losses to the State Grid

[0003] In order to prevent the transmission tower from being damaged due to the swaying of the transmission wire, there has been a Chinese invention patent "A Shock Absorbing Insulator for Transmission Wire" with the authorized announcement number CN102509592B, by adding elastic or magnetic fluid between the umbrella plates The buffer can overcome the alternating load of the transmission wire and effectively protect the transmission tower, but the shock-absorbing insulator can only buffer the vibration energy of the transmission wire in the vertical direction, and the shock absorption effect is limited; in order to solve the above technical problems, an improved Insulators with shock-absorbing functions are necessary
