Combined suspension ring rod protection device

Abstract

The invention provides a combined suspension ring rod protection device. A cylinder at one end of a single-lug ring 3 is inserted in a round hole of a shell. Two clamp blocks 4 are mounted in rectangular grooves of the shell. The two clamp blocks 4 and the cylinder of the single-lug ring are in contact, forming a 90 degree included angle. A conical groove is arranged in the cylinder of the single-lug ring. The front end contact part of each clamp block is provided with a conical inner arc. The two clamp blocks are both pushed by powerful springs, so that the conical inner arcs are clamped by the conical groove in the single-lug cylinder tightly. The powerful springs 5 are limited by two plug screws respectively and elasticity magnitude can be adjusted. A double-lug ring 1 is in hooked connection with a cross rod. The single-lug ring is in hooked connection with a strain insulator string for use. The rod protection principle is that when powerful typhoons or violent typhoons invade and the wind power acting on a lead reaches a specific force value, the conical groove in the single-lug cylinder acts on the conical inner arcs of the clamp blocks to push the powerful spring to retract; finally the single-lug cylinder slips out of the shell and falls off along with the lead; in this way, force acting an electric rod by wind is reduced substantially and electric rod breakage is prevented.

Description

Technical field: [0001] The invention relates to the field of safe operation of power transmission and distribution lines, can prevent tensile poles from being broken by a strong typhoon, and is a device for protecting power transmission and distribution lines against typhoon. Background technique: [0002] Thousands of weather and various natural disasters have caused heavy losses to human society; intensified typhoons, thunderstorms, and bird infestations have caused immeasurable losses to the power system; according to relevant reports, several super typhoons invaded this year, causing a lot of power transmission and distribution lines. Pole is dismantled, so the loss of power outage and emergency repair is heavy. If high-strength pole is replaced, the cost is extremely high; the company follows the national energy-saving and emission-reduction policy, and follows the reliability and intelligent operation management of the State Grid and China Southern Power Grid. Development ...

Problems solved by technology

[0002] Thousands of meteorological events and various natural disasters have caused heavy losses to human society; enhanced typhoons, thunderstorms, and bird encroachments have caused immeasurable losses to the power system; according to relevant reports, several super typhoons have invaded this year, causing many power transmission and distribution lines The poles were broken, so power outages and emergency repairs suffered heavy losses. If high-strength poles were replaced, the cost would be extremely high; the company follows the energy-saving and emission-reduction policies advocated by the state, and follows the grid reliability and intelligent operation management principles of the State Grid and China Southern Power Grid Corporation. Development direction, professional research and development of energy-saving, low-cost protection devices
