Bird-prevention umbrella hat for high-voltage power transmission line insulator

Abstract

The invention relates to a bird-prevention umbrella hat, in particular to a bird-prevention umbrella hat for a high-voltage power transmission line insulator. The bird-prevention umbrella hat comprises an insulator body, wherein a main support umbrella post is fixedly arranged at a central position of a top end surface of the insulator body and is in a vertical state, movable hat plates are respectively hinged with post surfaces of a left side and a right side of a top end of the main support umbrella post by hinge seats, a support force-applying block is arranged at a middle position of a front side of the main support umbrella post, the support force-applying block and the movable hat plate at the left side and the support force-applying block and the movable hat plate at the right sideare connected by force-applying connection rods which are symmetrically arranged, a lifting guide block is arranged right below the support force-applying block, the support force-applying block and the lifting guide block are integrally connected by a short connection rod arranged at a middle part, a rotation disc is further arranged right below the lifting guide block, a disc surface of the rotation disc faces a right forward direction, and a disc body is connected with the lifting guide block by a power push-pull rod.

Description

technical field [0001] The invention relates to the technical field related to electric equipment, in particular to a bird-proof umbrella cap used for insulators of high-voltage power transmission lines. Background technique [0002] The main function of the insulator is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are stipulated. If under the specified operating voltage, lightning overvoltage and internal overvoltage, there will be no breakdown or flashover along the surface; under the specified long-term and short-term mechanical load, no damage or damage will occur; After long-term operation under electric load and various environmental conditions, there will be no obvious deterioration; the fittings of the insulator will not produce obvious corona discharge phenomenon under the operating voltage, so as not to interfere with radio or TV reception. Because insulators are widely used devices,...

Problems solved by technology

In the past, anti-bird thorns were installed. The anti-bird thorns are made of steel bars to make a bunch of thorn-shaped needles and added to the top of the insulator to prevent big birds from landing. This method requires a lot of work, is difficult to install and disassemble, and is expensive. , while the traditional bird-proof umbrella cap structure is often fixed in form, it is easy to cause birds to stop directly on the cap plate, which affects the safety of high-voltage power transmission, and needs to be redesigned
