Multi-functional modular post insulator

Abstract

The invention provides a multi-functional modular post insulator. An upper fitting 1 is crimped and fastened on the mandrel of an insulator 8; an insert 4 is closely connected with a line pressing seat 2; one end of the insert 4 passes through a hole at the upper end of the upper fitting 1; the tail of the insert 4 is sleeved with and fastened by a spring ring 5; two screw rods are fixed on the line pressing seat 2; a pressing block 3 sleeves the two screw rods; holes are formed at the upper end of the pressing block 3; the lower end of the pressing block is in the shape of a bent hook; the lower part of the multi-functional modular post insulator is provided with a steel pin 9; one side of the steel pin 9 is provided with an arc striking ball 10 ; the arc striking ball 10 faces an arc striking rod which avoids the shed discharge of the insulator and is bent inwards; an optimal discharge gap is set between the arc striking ball 10 and the arc striking rod 7; when the insulator is subjected to lightning strike, freewheeling power-frequency arc can be made to be led to the discharge gap to be burnt, and therefore, a conductor and the insulator can be protected from being burnt out; and an insulating cover 6 is provided with thin-bar-shaped bird repelling devices, so that birds can be prevented from resting and staying on the insulator, and therefore, tripping caused by pollution to a line caused by the defecation of the birds can be avoided.

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. The cost is extremely high; the reproduction of birds is also increasing; according to reports from power departments in many places, power transmission and distribution lines are subjected to birds excreting feces and even building nests, which causes insulation flashover trips, which is one of the main reasons for line trips; With global warming, the weather of thunder and lightning is increasing unabated. The loss of power system caused by lightning strikes is obvious to all. Lightning strikes and disconnections of insulated wires occur frequently; any such kind of power outages and emergency repairs cause heavy losses.
