Interval rod used for insulator chain

Abstract

The invention relates to an interval rod used for an insulator chain. The insulator chain comprises a set square, an II font insulator chain assembly and a horizontal connecting rod, wherein the II font insulator chain assembly is vertically arranged on two ends of the set square and is formed through connecting the insulator chain, a parallel hanging plate and a hanging plate in series; and the horizontal connecting rod is connected to the insulator chain at a horizontal direction. Two ends of the connecting rod are provided with connection assemblies which are movably connected to the insulator chain. By using the interval rod, through additionally installing the interval rod on suspension insulators in an electric transmission line, a problem that the suspension insulators swing mutually is solved, and line safety and reliability are increased.

Description

technical field [0001] The invention relates to power transmission equipment, in particular to a spacer bar for insulator strings. Background technique [0002] The insulator string spacer is an important part of the power grid, which directly affects the stability of the power grid and the reliability of power supply. Insulator strings are used to suspend wires and insulate wires, towers and the earth, and are one of the key equipment in transmission lines. However, due to climate change and increasing windy weather, the mutual swing between insulator strings has brought serious threats to safe operation. [0003] In the existing insulator strings, the method of adding heavy hammers, adjusting the position of the tower, and changing the suspension or assembly of the insulator strings is often used to improve the wind damage resistance of the insulator strings. However, there is no good solution for preventing the mutual swing between the suspension insulator strings of th...

AI Technical Summary

Problems solved by technology

However, there is no good solution to prevent the mutual swing between the suspension insulator strings of the transmission line.

The existing insulator string spacers are generally connected by ordinary rod-type insulators and ordinary wire clamp fittings, which is not ideal for suppressing the swinging phenomenon between the insulator strings, causing vibration and mutual whipping between the insulator strings, causing damage to the transmission line, and Due to the simple structure and poor processing technology of the existing insulator string spacers, there are also problems such as poor strength, difficult transportation, short product life cycle and high maintenance costs.
