Column type porcelain insulator for high-voltage line

Abstract

The invention relates to a column type porcelain insulator for a high-voltage line, which comprises a ceramic insulating core and a base, and the bottom of the ceramic insulating core is fixedly connected with the base; the ceramic insulating core comprises a ceramic insulating column, a plurality of large umbrella skirts and a plurality of small umbrella skirts, the ceramic insulating column, the plurality of large umbrella skirts and the plurality of small umbrella skirts are integrally formed, and the plurality of large umbrella skirts and the plurality of small umbrella skirts are distributed on the outer side wall of the ceramic insulating column at intervals in the length direction of the ceramic insulating column; one end of the ceramic insulating column is fixedly connected with the base, and the other end is provided with an accommodating groove for accommodating a cable; a connecting stud is arranged in the ceramic insulating core, the bottom end of the connecting stud extends out of the base to form a fixing stud, and the fixing stud is in threaded connection with a fixing nut. The operation reliability and safety of the high-voltage power transmission line can be effectively improved, and the effect of prolonging the service life of the insulator is achieved.

Description

technical field [0001] The present application relates to the field of post-type insulators, in particular to a post-type porcelain insulator for high-voltage lines. Background technique [0002] With the development of modern society, the use of electricity is becoming more and more common. Usually, in order to avoid excessive loss, electricity is usually transmitted in the form of high voltage. High pressure transmission loss is less, and finally it is used after being transformed into a suitable voltage. Generally, High-voltage cables are installed at relatively high places to avoid danger due to accidental touch or other reasons. The cables and poles are usually connected with insulators. The first is high safety, and the second is to prevent damage caused by lightning. Insulators There are many classifications, and the most widely used is porcelain insulators. [0003] Insulators are special insulation controls that can play an important role in overhead transmission l...

AI Technical Summary

Problems solved by technology

[0006] In order to improve the low tensile strength of the existing pillar-type porcelain insulator products, the connecting body part has poor bending moment resistance, which is easily affected by accidental factors, resulting in fracture and damage at the connection between the porcelain insulator body and the base, and affecting high-voltage transmission lines. To deal with the problems of operational reliability and safety, this application provides a post-type porcelain insulator for high-voltage lines
