Multifunctional protecting post insulator

Abstract

The invention provides a multifunctional protecting post insulator. A wire clamping base 1 in an insulating cover 5 is crimped and fastened to a core rod of a lightning-proof insulator; two breaking groove-containing screw rods 3 with V-shaped grooves (3.1) are fixed on the wire clamping base 1; a wire crimping block 2 with V-shaped grooves (2.1) sleeves the two breaking groove-containing screw rods 3; and a hole is formed in the upper end of the wire crimping block 2 and the lower end is in a hook form, so that the wire crimping block can rotate upwards to facilitate wire installation; the wire crimping block rotates downwards in place after a wire is installed in place; and two torque nuts are screwed into the groove-containing screw rods 3 and are alternately screwed in place. According to the pole protection principle, when the wind action reaches certain force on the wire in a severe typhoon attack, the V-shaped grooves (3.1) of the two groove-containing screw rods are stretched to crack and the wire slips downwards, so that the action force of the typhoon on a line pole is greatly reduced; and the pole is prevented from being broken off. A steel leg is arranged at the lower part of the multifunctional protecting post insulator; an arc striking ball is arranged at one side of the steel leg; an arc striking rod discharges around umbrella skirts of the insulator and is bent inwards; an optimal discharge gap is set between the insulator and the arc striking rod 7; and a power-frequency arc of a follow current is led to the discharge gap for burning in a lightning stroke, so that the wire and the insulator are prevented from being burnt out. According to the multifunctional protecting post insulator, the insulating cover 5 is provided with thin rod-like bird repellers 11, so that the problem that the line is stained for tripping since birds stop and stay on the insulator to defecate is prevented. The insulator is a four-in-one multifunctional product of achieving wire insulating support, wind prevention and pole protection, arc striking and lightning protection and bird damage prevention; the insulator can be repeatedly used only by exchanging the two breaking groove-containing screw rods or the wire crimping block when the line is repaired and repeatedly suspended; and the insulator has the characteristics of being simple and compact in structure, convenient to install, simple in line, low in cost and the like.

Description

Technical field: [0001] The invention relates to the field of safe operation of power transmission and distribution lines, which can prevent the lines from suffering more and more serious natural disasters, and is a multifunctional protective post insulator for power transmission and distribution lines. Background technique: [0002] In the process of human development, higher and newer requirements have been put forward for energy. At the same time, the emission of greenhouse gases on the earth will also continue to grow, which will bring greater pressure to the development of the social environment. At present, countries around the world have successively proposed the concepts of environmental protection, high efficiency, safety and energy saving. In this concept, in order to truly realize the high efficiency, safety, environmental protection and energy saving of energy supply, the emergence of smart grid is needed. Enhanced typhoons and thunderstorms have caused immeasu...

AI Technical Summary

Problems solved by technology

Enhanced typhoons and thunderstorms have caused immeasurable losses to the power system; according to relevant reports, several super typhoons have invaded this year, causing many poles to break off power transmission and distribution lines. And the cost is extremely high; the reproduction of birds is also increasing; according to the reports of power departments in many places, power transmission and distribution lines are subject to birds excreting feces, and even nesting, which causes insulation flashover and tripping, which is one of the main reasons for line tripping 1. With the global warming, the weather of thunder and lightning has increased unabated. The loss of the power system caused by lightning strikes is obvious to all. Lightning strikes and disconnections of insulated wires occur frequently;
